ATI X display flickers badly after system resume

[Swâmi Petaramesh]

Binary package hint: xserver-xorg-video-ati

After resuming from suspend to RAM, X display flickers badly and apparently at random ; image is visible and computer "usable" - not hung - but always badly flickering until reboot. Shifting back and forth to text console then to X doesn't help X. This happened with ati_drv but, in the old days where fglrx did manage this card (until 8.10 Intrepid if I remember well), it was OK. This problem appeared as soon as I had to shift to ati_drv for «fglrx not supporting "old" cards in new Xorg anymore» :-(

WORKAROUND: After resuming from hibernate to disk, display is OK.

Suspending my system using « pm-suspend --quirk-radeon-off --quirk-vbemode-restore --quirk-vbestate-restore --quirk-vbe-post » as proposed in https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/318325/comments/9 doens't help. At resume my system's dispaly's still flickering.

Confirming that on my system X display is correct after resume from "hibernate to disk" even if the display was flickering (from a resume from suspend) at the time the system got hibernated to disk.

Well, next I'd like to forward this issue upstream, but first it must be retested on latest development version of Ubuntu (maverick) to make sure the issue still happens there with the latest code. ISO images are available via http://www.ubuntu.com/testing/. If you can reproduce it in the LiveCD environment, you shouldn't need to modify your installed system. Once you've reproduced it, run 'apport-collect 560104' to attach necessary debug files.

[Bryce Harrington (bryce)]

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.

[Swâmi Petaramesh (swami-petaramesh)]

This bug is still there and has been there for around 4 years without a fix.

Swâmi Petaramesh, thank you for your comments. Could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:
