Created attachment 28904 [details] x1600pro AGP lspci output I own an ATI AGP x1600pro, I've been trying to use the latest kernel versions with KMS enabled with no success. It only successfully boots, if I manually disable APG mode setting on Kernel radeon.agpmode=-1 But, it cannot be used on daily basis. It is too slow to redraw window, scrolling and painfully slow to playback video. It is attached on this message a lspci -vnnx of my hardware. Hope that helps.
Fixing bug title to show up on radar easier. Do any of the other AGP modes work? Could you test with 1, 2, 4, 8 and see if any of those work?
I already did that: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/496653 Also, since last friday, nomodeset stop working on disabling KMS I had to disable compiz to make it usable again.
On the thinkwiki mailing list, there are a few more users reporting this, including me. Running Debian/testing & unstable (I guess that says enough) on a Thinkpad Z61m. which has a VGA compatible controller: ATI Technologies Inc Radeon Mobility X1400. KMS is enabled by default on Linux kernel 2.6.32-5-68, and on Testing/Unstable X (X.Org X Server 1.9.4) won't work if you disable it.. My previous work-around (disabling KMS in /etc/modprobe/radeon-kms.conf) had to be undone. It currently boots fine, but the screen will start flickering after a while. Sometimes the flickering is so fast everything turns into a blur, and sometimes you can still see what is on the screen.. Not sure what is the matter, but on the thinkwiki mailing list it was described as: "The GPU loses somehow its synchronization over time." It resets if I close the lid of the laptop. But it is no fun doing that every 30 seconds or so :-)...

Your cards are not AGP and the symptoms are not related to this bug at all. Please file a new bug and include your xorg log and dmesg output.
