I had the following error when I was trying to play Diablo 2 Code: [igor@virus ~]$ wine .wine/drive_c/Program\ Files/Diablo\ II/Game.exe fixme:advapi:SetSecurityInfo stub err:wgl:X11DRV_WineGL_InitOpenglInfo couldn't initialize OpenGL, expect problems err:d3d_caps:WineD3D_CreateFakeGLContext Can't find a suitable iPixelFormat. err:d3d:InitAdapters Failed to get a gl context for default adapter After a week of googling, crazy ideas and tries, I finally added my username to group called video and it solved my problem. Code: [root@virus ~]# id igor uid=500(igor) gid=500(igor) skupiny=500(igor),1234(dokumenty) [root@virus ~]# usermod -aG video igor [root@virus ~]# id igor uid=500(igor) gid=500(igor) skupiny=500(igor),39(video),1234(dokumenty) newbie mistake :)
