Hi Zhenyu,

Thanks for your reply. I'm running kernel version 2.6.18-4-amd64
(Debian). The driver being used is i810, itsd man page says it
supports the chip:

       i810 supports the i810, i810-DC100, i810e, i815,  i830M,  845G,  852GM,
       855GM, 865G, 915G, 915GM, 945G, 945GM, 965G, 965Q and 946GZ chipsets.

Not sure how to check the modules version modinfo prints the following:

german:~# modinfo drm
filename:       /lib/modules/2.6.18-4-amd64/kernel/drivers/char/drm/drm.ko

Also, the drm and intel_agp are not being loaded at startup (but
loading them does not solve the problem). Do I need to upgrade?
