[RV530] screen flickering, lucid lynx beta 1 [Needs pll quirk]

[magnunor]

Binary package hint: xserver-xorg-video-ati

Starting at the loading screen at boot, and continuing until shutdown: the screen flickers horizontally and occasionally "jumps".

Adding radeon.new_pll=0 to the kernel command line solves the issue.

Reassigning to the kernel because it needs to use new_pll=0 by default on this device.

[Aurélien Begel (pcrider-gmail)]

I am affected by this problem too, but with an ATI Radeon Mobility X1400 (RV515).
Adding radeon.new_pll=0 to the kernel command line solves the issue (or passing new_pll=0 to the "radeon" kernel module).

Please tell me if you need more details, or if I need to make a separate bug report.

See attached lspci.txt

Aurélien Begel: Please file a new bug by running ubuntu-bug linux so we can have all of the info. If you don't mind, add the tag needs-pll-quirk to it as well after you file it. Thanks!

I've built a test kernel with Robert Hooker's patch on top of the Lucid tip, please test it and see if it resolves the problem.

The kernels are here:

Thanks!

+1 on this issue - card is a ATI Radeon Mobility X1400 on a Dell E1505 laptop

Solved my adding the radeon.new_pll=0 to the grub boot...

[Gert (mar-rocca)]

Same issue - Radeon Mobility X1400 on an ASUS A6j series running ubuntu lucid

Adding radeon.new_pll=0 allowed an usable system but minor flickering on the right side while scrolling on fullscreen windows remains.

Hi,

got the same problem with lucid beta 1 as of 04.04.2010.

Adding radeon.new_pll=0 to kernel options solved this as it seems.

System is a Thinkpad R60 with Radeon Mobility X1400.

[Gert (mar-rocca)]

the flickering on the right side remains with kernel 2.6.34rc1 BUT it goes away changing the resolution to 1200x780 (instead of 1200x800, which I've *always* used)

[Aurélien Begel (pcrider-gmail)]

Linux kernel version 2.6.32-20-generic fixes the problem on my computer. Thanks!

[magnunor (magnunor)]

Kernel version 2.6.32-20-generic fixed the issue; no more flickering or screen "jumping".

[Jeremy Foshee (jeremyfoshee)]

magnunor,
      Thanks for following up on this. I am glad the issue is resolved for you. I have marked this bug Fix Released.

Thanks!
