After an update of my Debian SID, Compiz wont start regulary. Trying some commands, i see the following errors:

acido@hp:~$ glxinfo
Error: glXCreateContext failed

acido@hp:~$ compiz --replace
Fatal: Failed test: texture_from_pixmap support
Checks indicate that it's impossible to start compiz on your system.

acido@hp:~$ compiz-check
Checking for texture_from_pixmap... [FAIL]
Checking for non power of two support... [FAIL]
Checking for composite extension... [ OK ]
Checking for FBConfig... [ OK ]

I have an nVidia video card and I use the proprietary drivers (so i don’t know if the same things happens with Ati or Intel video cards) and these errors happens by an upgrade of xserver-xorg package. You have to recompile yours drivers and that’s all.

linux, debian, compiz, xorg, nvidia
