(In reply to comment #8) > Is this still an issue with kms or newer versions of the driver?
Yes, it is (sorry for my lack of updates), but with KMS is different. I'm currently using Debian Squeeze: xserver-xorg-video-radeon 1:6.13.1-2 xserver-xorg 1:7.5+7 xserver-xorg-core 2:1.7.7-8 libdrm2 2.4.21-1~squeeze3 linux-image-2.6.32-5-686 2.6.32-26 (it contains drm from 2.6.34) When KMS is turned on (default behaviour), the flickering stars when (I think) the kernel module is loaded (I don't know if radeon or drm) and when Xorg starts, the flickering is fixed (just like Xorg change some values) and virtual consoles work again. How can I help to debug this issue? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/175243 Title: [Mobility 9000] screen flickers only if text tty entered (radeon) Status in xserver-xorg-driver-ati: Invalid Status in xserver-xorg-video-ati package in Ubuntu: Invalid Bug description: I "upgraded" to Gutsy by doing a clean install a couple of days ago and now have noticed a strange screen flickering bug. I have a radeon mobility 9000 on a Dell Inspiron 600m, and did not have this problem previously with Feisty Fawn. The bug is screen flickering in text consoles _and_ X. Interestingly, though, this bug does not occur if I boot into splash and then it goes straight to X. I am able to log on and use desktop effects and such without any flicker. However, the moment it has to switch to a text tty/vt, whether through a Ctrl-Alt-Fn or after I log out when X restarts, it starts flickering and the flicker makes everything pretty much unusable (well quite annoying at least). I tried booting with vga=normal but that doesn't change anything. No splash on boot doesn't help. I believe this has something to do with the new text tty changes in Gutsy vs Feisty, but am not sure exactly what these are, so if someone has some advice maybe on something I can do to try to mess with these that would be great (I'm pretty sure it's not an X issue per se b/c it does not seem to happen the first time X starts and I log on after splash; oh yeah also it does _not_ happen when BIOS is starting and in the initial splash; however after we go to tty I can't get the flicker to stop).
