[RV515] screen flickers in lucid lynx beta1 [Needs pll quirk]

[Aurélien Begel]

As already reported by other users in bug reports #544662 or #543045, my laptop screen flickers in Ubuntu Lucid Lynx beta1. This can happen at boot time of after a few minutes, but when it begins it stays until shutdown or reboot.

As for other users, this issue is solved by passing "radeon.new_pll=0" parameter to the kernel at boot time, or by passing "new_pll=0" parameter to "radeon" kernel module.

My laptop is a Dell Inspiron 6400 (aka E1505), an ATI Radeon Mobility X1400 video adapter and a 15.4" 1680x1050 panel. (See attached files for details)

[Steve Conklin (sconklin)]

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:

http://people.canonical.com/~sconklin/test-i915/

Thanks!

[Aurélien Begel (pcrider-gmail)]

Thanks Steve,
nevertheless I am using amd64 architecture, so may I get either an amd64 kernel, or the source code so that I can compile it myself?
(I can of course set up a new i386 system, but I think this will take more time.)

[Steve Conklin (sconklin)]

Sorry, I'm building amd64 now, I'll post a note when it's available

[Aurélien Begel (pcrider-gmail)]

Steve, I eventually set up a new Ubuntu system using i386 architecture, and then set up http://people.canonical.com/~sconklin/test-i915/linux-image-2.6.32-18-generic_2.6.32-18.28~spcintelfixes01_i386.deb package.
However the bug is still there...

Aurélien Begel, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, 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:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.11

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.
