Summary: The Witcher 2.0 (Gog.com): black screen on launch,
                    have to kill X
           Product: Wine
           Version: 1.3.21
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

On my ubuntu 11.04 laptop, where glxinfo | grep str says
OpenGL renderer string: GeForce GTS 360M/PCI/SSE2
OpenGL version string: 3.3.0 NVIDIA 270.41.06
I can install Witcher 2 and run its config utility,
but launching the game itself yields a black screen
even if you tell it to run in a window on a virtual desktop.
Killing the game doesn't fix the screen, so it kind of sounds
like a problem with the X server.
Some people in the appdb have reported success with 
  winetricks glsl=disabled d3dx9
but that didn't help here.
