4850 ati driver problem, Debian testing, no adapters found,"XAANoOffscreenPixmaps"
I've tried these drivers: ati, radeon, radeonhd and fglrx.
fglrx seems to work fine, but Firefox is unusable with it. there are some strange stripes all over the page, they occur randomly when scrolling.
"XAANoOffscreenPixmaps" did NOT help at all.
so, i tried reverting to "ati", "radeonhd". but now i get "no adapters found" in xvinfo, so mplayer does not play movies like it should.
also, 'sudo dpkg-reconfigure xserver-xorg' does not work, it just exits.
First, don't use 'radeonhd'. It's undeveloped and unsupported. Use the 'ati' driver and attach the /var/log/Xorg.0.log file that is generated so that we can see what the problem is.
Your kernel reports that KMS is enabled, and your X server says it isn't. This is *often* a sign that the kernel DRM isn't getting loaded to the last minute, when X starts, and KMS doesn't have enough time to activate. Can you boot into run level 3 (or whatever runlevel Debian uses that has X disabled), log in, run 'modprobe radeon' (as root or with sudo) and then try to start X with 'startx'?
i forgot one probably important thing, i upgraded the whole computer: motherboard, cpu, gfx card.. without reinstalling debian.
but that was long time ago.
the problem is that everything about fglrx is already uninstalled in aptitude. I made a mistake by installing it from ati installer instead of aptitude.
they didn't provide uninstaller, except some pathetic sh script that didn't seem to work.
(I also had installed fglrx in aptitude, that might have increased the confusion :/ )
anyway, I'll keep trying to remove it completely.
thanks for the help.
