Summary:
  What works:
    Installation, Patching, Intro Video, Cinematics, Gameplay
  What was not tested:
    Extended gameplay
  Needed to install properly:
    1 - create dvd images of the disk and mount those
    1 - install both 'vcrun2010' and 'd3dx9_36' (using winetricks)
    2 - disable GLSL using: 'winetricks glsl=disabled'
    3 - set the correct amount of video memory: "VideoMemorySize"="1536" (set the correct amount for YOUR Video Card)
    4 - run 'wine Configurator.exe' to set the correct video settings
    5 - run 'wine witcher2.exe' once, to get the launcher working (drag it to an edge of a screen to use the menu)
  Test system used:
    Qosmio X500-15F gaming laptop:
      video card: NVIDIA GTX 460M - 1536MB
          memory: 8GB SO-DIMM DDR3-1333
             cpu: Intel i7-2630QM Quad Core @2.00Ghz
  
Extended Problem/Solution Guide:
(Windows partition or VM => NOT NEEDED, all run on Ubuntu)

Assumptions:
 you use the following wine prefix:
   WINEPREFIX="~/wineprefixes/TheWitcher2" 

problem:
   half way through the installation it asks for dvd 2, but replacing the dvd and pointing it to the correct device doesn't help
solution:
  create an Image of both DVD disks(for example using dd)  and mount those:
    1 - insert dvd1
    2 - sudo umount /media/TW2_EFIS_Disc1
    3 - sudo dd if=/dev/cdrom of=~/thewitcher2_dvd1.iso bs=1M
    4 - wait until the command completes, and then type 'eject'
    5 - insert dvd2
    6 - sudo umount /media/TW2_EFIS_Disc2
    7 - sudo dd if=/dev/cdrom of=~/thewitcher2_dvd2.iso bs=1M
    8 - wait until the command completes, and then type 'eject'
    9 - sudo mkdir /media/disk1 /media/disk2
   10 - sudo mount -o loop ~/thewitcher2_dvd1.iso /media/disk1
   11 - sudo mount -o loop ~/thewitcher2_dvd2.iso /media/disk2
   12 - cd /media/disk1
   13 - wine setup.exe
   14 - when asked to insert dvd 2, just give the new path name 'z:\\media\\disk2' (as in replacing the '1' with '2')

problem:
  wine Launcher.exe => doesnt work yet

  start the game once directly through 'wine witcher2.exe'

problem:
  can't click menu items in Launcher
solution:
  drag the Launcher to an edge of the screen first

problem:
  the cinematics are black and blurry
solution:
  use 'wine Configurator.exe' in the bin folder of the game, and lower your video settings
