I'm also having the same issue (with compiz enabled) when maximizing the video player. I'm on 9.10, NVIDIA Driver 190.32, Quadro NVS 110M (256 MB with TurboCache) My xorg.conf is: Section "Monitor" Identifier "Configured Monitor" EndSection Section "Screen" Identifier "Default Screen" Monitor "Configured Monitor" Device "Configured Video Device" DefaultDepth 24 EndSection Section "Module" Load "glx" EndSection Section "Device" Identifier "Configured Video Device" Driver "nvidia" Option "NoLogo" "True" EndSection Note that I have COMPIZ_OPTIONS="$COMPIZ_OPTIONS --indirect-rendering " in /usr/bin/compiz to avoid the full-screen black windows problem for example: attila@blackbird:~/Desktop$ vlc urka.avi VLC media player 1.0.2 Goldeneye [0x16a3888] main libvlc: Esecuzione di vlc con l'interfaccia predefinita.

This probably reflects a bug in the program. The error was 'BadAlloc (insufficient resources for operation)'. (Details: serial 353 error_code 11 request_code 133 minor_code 19) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) attila@blackbird:~/Desktop$ mplayer urka.avi MPlayer UNKNOWN-4.4.1 (C) 2000-2009 MPlayer Team mplayer: could not connect to socket mplayer: No such file or directory Failed to open LIRC support.
