Thanks for taking your time! =)
Here's what my /proc/driver/nvidia/agp/status looks like:
AGP Rate: 4x
Fast Writes: Disabled
I'm using 2.4 and I will try 2.6, just had some troubles with the nvidia driver in 1.6, but I havn't tried so much yet.
And here are some errors in the XF86 log:
(WW) The directory "/usr/lib/X11/fonts/cyrillic" does not exist.
Entry deleted from font path.
(WW) Open APM failed (/dev/apm_bios) (No such device)
(II) LoadModule: "pex5"
(WW) Warning, couldn't open module pex5
(II) UnloadModule: "pex5"
(EE) Failed to load module "pex5" (module does not exist, 0)
(II) LoadModule: "xie"
(WW) Warning, couldn't open module xie
(II) UnloadModule: "xie"
(EE) Failed to load module "xie" (module does not exist, 0)
I've googled them, and it seems like I just should ignore them.
And finaly, the glxinfo looks good, no errors or strange things.
I'll try more tomorrow
thank you so much!
