HowTo / Notes

Sugestions about Test result submit

This notes was updated: August 03 - 2013

First of all, thank you for spend your time helping wine to get better,

I like to make some suggestions to make the tests results more organized and better to all users:

  • Put your PC specifications at the Extra Coments section like your video card, cpu, and system memory.
  • It's important to put your video card drivers into extra coments section.
  • Specify if you installed the game into a fresh prefix (or not), and what programs are you installed.
  • Tell what version of the windows emulation you use in your wine (at winecfg).
  • Add a comment about what is don't working.
  • Tell if you put any official or unnoficial path on your game like a diferent version of some .exe or a modification on some config file from the game.
  • Please, don't put tests results like "Everything is working" or "Everything is not working".

These are just suggestions to make tests result more clean and more fast to be submitted.

How-to install the game

You need:

  • A recent version of wine, 1.3.28 or newest, it's recommended the lastest release.
  • A video card with 3D Acceleration suport on your unix.
  • The official 3D driver installed and working for that card.
  • It's not necessary a clean prefix, but it's recommended.

First download steam from here, install following the steps on Steam page and install the game trought steam.

Be sure that 3D support is working, you can check this by typing the follow command:

glxinfo | grep "direct rendering:"

It's also recomended to install the following fonts: tahoma.ttf, arial.ttf and verdana.ttf.

I recommend that you install the Visual C Runtime, download-it from here and here and install on your prefix.

To override the wine vcrun with the native one you need to create a file called vcrun.reg with the follow content:


Then run the follow command:

env WINEPREFIX="(your-prefix)" WINEDEBUG="fixme-all" wine regedit ./vcrun.reg

The game shoud work fine. Any problem, you can see the Troubleshoot notes, post a comment or submit a bug at Bugzilla.


 For problems related with Steam itself, please visit the Steam Official Release page.

Can't change the resolution or go to fullscreen.

Right click on the game at steam and go to: Proprieties > Set Launch Options and type:

-full -w (your width resolution) -h (your height resolution).

Portal 2 is crashing before you enter the menu.

You need to check your game cache, on Steam right-click on portal 2 and go to Proprieties > Local Files (Tab) > Verify integrity of game cache.

Some people with  Portal 2 is still suffering with the problem "crashing before the menu" and verifying the integrity of the game don't work. Solutions that worked for some people:

  • Uninstall portal 2, and download again through steam (don't reinstall from DVD, download-it again).
  • Install steam through winetricks.
  • Disable the Steam Overlay by setting the gameoverlayrenderer library to disabled on winecfg.
  • Set winecfg to emulate Windows 7.

My suggestion is, if you tried everything and still have this problem, submit a new bug, or, ask to reopen the bug #26835.

Portal 2 has some ugly textures, or everything is yellow/green, the light is showing trought the wall.

Set the Multicore Rendering to Disabled/Off on graphics options into the game.

View more details about this bug here (Bug #24684).

When launch Portal 2 i got the "In order to run Steam properly on this version of Windows, the Steam service component must be installed." error.

The solution for this bug is to set the version of windows to XP, to do that, open your winecfg and set Windows Version to Windows XP.

The game is ramdomly crash after some minutes playing.

Try to check the integrity of the game, to do that, on your steam, right click on your Portal 2 Proprieties > Local Files (Tab) > Verify integrity of game cache.

Also, try to install these fonts on your wine prefix (drive_c/windows/Fonts)lucida.ttf, tahoma.ttf, arial.ttf and times.ttf.

The game wont start or crash at start.

Try to install vcrun2005 and vcrun2008, follow the How-To install tutorial.

The game is laggy on some maps, the FPS is very low.

Try to lower the AntiAliasing (AA), or even turn off AA.

General Troubleshoot.
  • Verify if your video driver is installed properly.
  • Install steam and Portal 2 to a separated prefix.
  • Set prefix version to Windows XP.
  • Close Portal 2 and steam, and reboot wine by typing wineserver -k.
  • Check integrity of the game trought steam, you can do that by right click on the game and going on Proprieties.
  • You can reinstall Portal 2 and Steam again in a fresh prefix, just copy the folder (your-prefix)/drive_c/Program Files/Steam/steamapps that contain all the Portal 2 files.
Old Problems.

Note: These problems don't affect the newest versions of wine, it's only here for precaution, if you have any of these bug's maybe you should upgrade your wine version.

Mouse randomly jumps around menu or in game.
This is caused by the new implementation of mouse input in wine, to solve-it, you need to run the game in Windowed mode or into a Virtual Desktop.

On wine older than 1.3.28 Portal Exists at Menu Screen.

If you're using a version older than 1.3.28 you're soffer Portal Exists at Menu Screen Problem (More info at bug #26835).

To solve the Portal Exists at Menu Screen, Download and apply this patch to your wine compilation. 

On wine older than 1.3.28 Portal ramdomly crash after 5 or more minutes of gameplay.

If you're using a version older than 1.3.28 you're soffer of the 5-Minutes crash (More info at bug #27877) and you have to apply one patch to solve.

To solve the 5-Minutes Crash, download and apply this patch to your wine compilation.

Portal 2 graphics problem
by Mike Freeman on Wednesday January 29th 2014, 14:06
I'm trying to run Portal 2 via Steam, through WINE, in its own separate WINE prefix, on Linux Mint 13. The computer runs on a Radeon HD 4200 with the latest proprietary Legacy drivers (Catalyst 13.1). I'm currently using WINE 1.7.11, but I've tried several others from 1.5, 1.6, and 1.7 versions.

When I launch Portal 2 from Steam, it displays garbage on the screen, like distorted remnants of old graphics memory, which flickers. I can hear sound (from the startup Valve video, the music behind the main menu, and the bleeps from moving the mouse over each menu option. But I can't see anything useful. I've tried every permutation of settings in the Catalyst control panel I can think of. I've installed every version of D3D library that winetricks offers, and I've tried without it. I have vcrun2005 and 2008 installed. I have tried all the "fixes" suggested in all of the forums I can find, although none describe a problem like mine. I've never seen this happen on any other WINE program.

Does anyone have any ideas of what to try next, other than wait for the excruciatingly-slow-in-coming native Linux version of Portal 2? Thanks!
Fullscreen and Full Resolution not registering
by Benjamin Mintz on Tuesday March 26th 2013, 13:09
On Portal 2, when I try to change the video resolution in the settings, I can't select 1920*1080, I can only select 1280*1024. Also, Portal 2 thinks it's in fullscreen mode, but it's not. Thus, I can't play Portal 2 in fullscreen on WINE; nor can I in full resolution. Any ideas?
New Workaround
by Mike on Thursday March 7th 2013, 9:01
I tried all the work arounds listed above and none of them worked. I search steam support for windows 7 and they suggested modifying the

steam launch options for Portal 2 by adding -Novid.

It fixed the problem for me. Skiped the intro credits and went straight to the splash screen. Just got done playing for 3 hours with no major hickups.
missing images in Portal 2
by Arthur Schüler on Sunday January 27th 2013, 11:40
I bought Portal 2 via Steam and installed the right Driver for my new ATI Radeon HD 4650 GFXCard. Then i launched Portal via Steam and it works fine but i am wondering about the black background at the Portal 2 Picture after the Valve Logo. Also i am getting a short moment with low brightness when i am klicking at something. Also there are many little or big Pictures which arent shown, or shown very dark. In the level editor the objekts are black squares and the walls of the test chamber are dark and black. When i launch the game everything works, there comes the voice and the white letters with "look up" and so. But all i can see its black screen with white letters and this 5 points in the middle. When Portal is loading something with this bluegreywhite circle at upper right and the blue points right down there is also no background image. And i dont know why but the main menu is very laggy too.

I hope you can help me. The GFXCard have got 512MB Ram and my Computer have got 2048 MB.

Everything works fine. except the 3D things...
by Arthur Schüler on Friday January 25th 2013, 5:54
So, i bought Portal 2 via Steam and launched the Steam client with wine and the game via this client. Everything works, the menu, the level editor and the options. But if i want to launch Singleplayer Game i am getting a white screen and nothing else. If i want to launch a self created level i am getting a black screen with a text "Left klick to make a blue portal". This text is wandering slowly down, out of the screen. and that was it... I dont know whats the problem! I hope you can help me!

The Steam service component must be installed.
by Cheeseness on Friday August 17th 2012, 4:25
Following today's update, I started receiving this error when launching Portal 2:

"In order to run Steam properly on this version of Windows, the Steam service component must be installed."

I was able to get around it by setting the Windows Version option in winecfg to Windows XP (it was previously Win 7).
frequent lags and random crashes
by Yaroslav on Friday July 13th 2012, 15:40
I experience random lags/freezes/hangs on most portal shoots and door openings. Game crashes sometimes.

This is "fixed" by setting shader detail to medium or low. I also disabled GLSL, don't know if this needed or not.

System crashes after ~10 minutes of Portal 2
by Moritz on Monday June 25th 2012, 10:08
After 10ish minutes of Portal 2 my system crashes: The sound hangs, the keyboard does not react to anything (not even the numlock-led). Only a hard reset helps from there.

Cant find anything in log files, because they also can't be written on a complete hang-up.

I'm having the same trouble everyone is having below, but on 1.5.4. I have winetricks installed with Visual C++, the latest fglrx drivers for my AMD HD 7870 and kernel. I'm at a loss. I uninstalled and reinstalled to no effect.
Perpetual Testing Initiative
by Cheeseness on Tuesday May 8th 2012, 23:27
I'm tooling around in the new editor that came out with today's DLC release, and it *seems* to work OK. I haven't tried publishing anything yet (I'll submit some test results when I get around to that).

Unforunately, the Steam overlay still doesn't work with Portal 2, so none of the documentation for the editor is accessible :(
crash bug for wine 1.4
by caleb dutton on Wednesday May 2nd 2012, 0:00
just like the 1.3 bugs, but im exceeded that mark, the patch did not seem to help unless i downloaded it wrongly,
heres a report
i cant seem to get winedebug=fixme+all or err+all working, perhaps because there were no fixme's or errors, just warnings, hmm

by Alberto on Tuesday April 3rd 2012, 12:01
Please add this to the "crashing before entering the menu" section:

* Make sure you don't have any absolute pointer device connected (drawing tablet, touch screen).
* Run directly portal2.exe with wine instead of opening the game in steam.

After finding out those quirks (I have wine 1.4) I can play in a multiseat box (single computer, two screens, two keyboards, two mice and two graphic cards with two user sessions).

Black Screen with Crosshairs
by Pryoidain on Tuesday March 13th 2012, 14:03
When loading Portal 2, everything appears to work (The menus do this goofy thing where they start really faded out then jump to being lit up) until I get into the game. I have full sound, I know I have mouse movement (because even though the game screen is black if I move the mouse up it responds in game), and a crosshair.

But everything else is black.

Running Gentoo Linux, wine-1.4, compiled with win32 options, opengl, etc etc etc, fixed ntlm_auth problems with steam, have corefonts installed along with the vc runtimes, and recently i went full hog and installed ALL the directx dlls. I also have glsl disabled.

Steam "Incomplete Installation" and "Completing Installation" errors
by Jeff Cook on Wednesday December 21st 2011, 0:03
If you get messages like "Completing Installation ... 1%" followed by errors like "Steam servers were too busy to fulfill your request. Error Code (2)" or "Error Code (55)", Steam is yelling at you for these reasons:

1. You are not running Steam from its normal installation path on C:\Program Files\Steam. Go into winecfg, make sure your C:\ drive is configured, and make this path exist.

2. You may think it'd be clever to symlink or something. Do NOT do this. Newer Valve games like LFD2 and Portal 2 choke to death if the folder used to access the game doesn't have certain likeable attributes (unsure what these are). A symbolic link will not fix anything, you will continue to get the same errors. You must move the Steam and steamapps folders into that path for real in order to launch.

I do not believe this is a WINE bug as many Windows configurations experience similar issues if Steam is not placed in the expected path or drive.

Spent a couple of hours struggling with this tonight. Portal 2 seems to run great after this workaround. Hope it helps someone out there.

Crash before menu
by Konrad Tlatlik on Thursday September 29th 2011, 15:48
I've installed portal2 according to the howto, experimented with the settings for quite a time, and I still can't get it to work. The crash looks exactly like the bug, but I'm using wine 1.3.29, so it shouldn't occur. Human sacrifices in the name of Cthulhu don't work either, however the blood splattered on my laptop does look pretty cool. Any help?
"5 minute crash bug"
by Cheeseness on Friday September 9th 2011, 2:48
The second patch in the howto is not the same patch listed as fixing the "5 minute crash bug". Wording of the howto might need to be changed if that patch is still required.

I'm still getting very frequent crashing (sometimes less than a minute) with 1.3.27 (from Fedora updates-testing) on F15 with UseGLSL disabled. Is anybody else still having problems too?

Crash when seeing yourself through portals in singleplayer
by Yann Kaiser on Wednesday September 7th 2011, 15:01
Noticeable especially when the first portal opens after you exit the motel room. The game will freeze for an instant and crash(inf recursion?). It does not happen in CO-OP.

fglrx / wine 1.3.27 / UseGLSL=disabled / borderless window
by Paul Moir on Sunday August 14th 2011, 21:12
Yes it's working for me now, with no cracks ever being used. (Only 4 months after purchasing the game. Thank you Valve, I'll remember that next time. Oh and a big non-sarcastic thank you to the Wine Devs!)

I did have some old PlayOnLinux stuff that was causing a bit of a problem because it was launching an older wine. Try running Steam.exe and portal2.exe from the command line.

I'm running Kubuntu, but I doubt that makes a difference. Same kernel and everything as you. I'm using the Ubuntu Wine PPA for installation.

Now just need to get sound working...

Ah, got it. Went over to ALSA:
Close all wine programs. ps -ax to make sure they're all gone. winecfg->Audio - uncheck OSS and check ALSA. Test Sound button produces sound. Now I get sound in portal2.

Only an annoying blinking cursor left to kill.
Portal 2 on Ubuntu Natty?
by Line Noise on Sunday August 14th 2011, 5:46

Has anyone had any success getting Portal 2 to run on Ubuntu Natty? (Without the SkidRow crack.)

I've installed Wine 1.3.26 which should have the patch that fixes the bug that was crashing Portal 2 before the menu. Unfortunately I haven't seen any change in behaviour.

If I run portal2.exe directly from the command line it just exits before the menu appears. If I run it from Steam then I get the "Completing installation ... 1%" dialog and then it says "Incomplete installation of Portal 2 (2)" :-(

I've tried verifying local game cache files. They all verify OK.

I've tried deleting server.dll and client.dll, then verifying. Steam re-creates those two files. Still doesn't work.

I've tried copying the game files from a working Windows installation. No dice.

I've completely deleted my Steam Wine prefix, reinstalled Steam and re-downloaded Portal 2. No luck.

Noone has reported that they have it working in Ubuntu Natty without the crack and as the patch that is supposed to fix the problem was to do with a more strict Linux kernel I'm wondering if perhaps the kernel that comes with Natty is even more strict and might need some more patching to Wine. I'm just guessing, though.

Any ideas?

I can provide debug output if needed.

wine 1.3.22
Portal 2 Steam version

I'm using Debian Squeeze x86_64 with Ubuntu wine packages.
The game was installed on a clean wine prefix with corefonts, vcrun2005, vcrun2008 and vcrun2010 installed via winetricks.

I have a NVidia video card (GeForce 8600GTS) and I'm using the proprietary drivers, version 270.41.06.

The game runs very smoothly aside from this problem.

by Dheart on Saturday May 7th 2011, 6:12
According to the steamforums that bug is fixed, however the game still doesn't work on wine and exhibits the same behavior? I suggest we reopen the bug as now it is certain that it is a wine bug.
File Systems

Is there anybody here who is running Steam and Portal 2 off an NTFS partition?

My girlfriend's laptop had what seemed to be the same problem under Windows. Converting her primary partition to NTFS sorted out the problem on that machine. I'm curious to know whether it makes a difference under Wine as well.
by Matt Helsley on Monday May 2nd 2011, 17:37
Would people please stop posting references to a certain crack?

It is NOT a fix if it exposes me to losing or having any restrictions on my steam account (or worse!). It is NOT a fix if it needs to be supplied by Valve rather than the Wine community.

All the posts reporting that "I got it to work" with this method are USELESS and, for some of us on this world, would require us to do something that is illegal. Notice how it also doesn't matter what I believe about DRM -- it's still illegal.

So please stop -- we understand that it "works". Now let's focus on working without it.

crashing question
by monkeyslayer56 on Wednesday April 27th 2011, 7:23
out of curiosity since in steamforums it seams the crash is filesystem/DRM related what filesystem do you guys have steam and portal 2 installed on? I have my steam and portal2 installed to a EXT4 filesystem and i get the crash, and i tried moving portal2 files to a NTFS partition and running from there (steam still on ext4) i still got the crash. i read were some guy got it to work on an ext3 with crossover. so just curious what filesystem you guys are using and if it crashes or not

appid not configured and jumpy mouse
by luke on Thursday April 21st 2011, 19:17
If you get an "appid not configured" error, and then the no steam message, run the game at least once BEFORE you apply the crack/patch.

If your mouse is "jumpy" and accelerates incorrectly, use the developers console to set the max fps to something like 30: "fps_max 30" and enable vsync.
Mouse constantly moves up and to the left during gameplay
by Jack Peirce on Thursday April 21st 2011, 16:28
My cursor is constantly moving up and to the left during gameplay. This does not happen in the menus.

If I set the in-game option "Ignore Windows Mouse Speed" this stops, but no movements of the mouse get registered at all and I can't look around.

This does not happen in other Windows games, or in regular use of my mouse.

by cyphaw on Thursday April 21st 2011, 14:53
Using skidrow's crack, the game works fine, but that is until chapter 8 (yes I played a lot), where new textures appear, making the fps drop to less than 1.

fixme:d3d_surface:fb_copy_to_texture_direct Doing a pixel by pixel copy from the framebuffer to a texture, expect major performance issues
err:d3d_surface:fb_copy_to_texture_direct Texture filtering not supported in direct blit

Nvidia users, please test the game without GLSL enabled:
./winetricks glsl-disable

And check if you have crashes on new game start or second level/save from second level loading.
And, please, check if it crashes or lags when you looking upon yourself though portals.

If it do any of this, please post corresponding backtraces (you'd better run the game with -nominidumps -nobreakpad command-line options) to corresponding bugs from list above.

New and fixed crack

If you're running with the SKIDROW crack to get past the splash screen, and you're getting intermittent or suspiciously well-timed crashes (such as 30 seconds after loading the first repulsion gel area in ch6), make sure to upgrade to the *new* SKIDROW crack named "Crack Fix".

managed to get portal 2 to run and load a saved game, but it crashes out after 20-30secs.

The DVD release works ridiculously well out of the box.
