Co mi neni uplne jasne, jak se u on-board karet urci velikost pameti. Hadam, ze se vezme to, co je v biosu prednastaveno jako sdilena pamet. A pripadne se to da upravit jeste nastavenim v xorg.conf. U me je to takhle:

Section "Device"
        Identifier      "Intel Corporation 82865G Integrated Graphics Controller"
        Driver          "i810"
        BusID           "PCI:0:2:0"
        Option          "UseFBDev"              "false"
        Option "VideoRam" "65536"
        Option "CacheLines" "1980"
        EndSection

Option CacheLines jsem vygooglil a bez ni vlc neotevre ani to okno s videem a hlasi chybu

X Error of failed request:  BadAlloc (insufficient resources for operation)

Jak jsem se dopatral, je tato option pro i810 driver, popis je napr. zde:

http://www.x.org/archive/X11R6.8.0/doc/i810.4.html

Option "CacheLines" "integer"

This allows the user to change the amount of graphics memory used for 2D acceleration and video. Decreasing this amount leaves more for 3D textures. Increasing it can improve 2D performance at the expense of 3D performance. Default: depends on the resolution, depth, and available video memory. The driver attempts to allocate at least enough to hold two DVD-sized YUV buffers by default. The default used for a specific configuration can be found by examining the Xorg log file.

Spis se tedy priklanim k nazoru, ze chyba bude nekde v dekodovani MPEG4 streamu. Ales
