[RV350] screen backlight off after resume-from-suspend when using ATI KMS

Resume works normally if I do not boot with "radeon.modeset=1". Resume technically works, but the screen never comes back. I can log in blind and reboot, etc.

I've forwarded this bug upstream to https://bugs.freedesktop.org/show_bug.cgi?id=24097 and subscribed you to it. Please follow up with them in case they need further information or wish you to test something.

Hi, I have a dell latitude 6400 laptop with an intel 4500 mobile graphics card.
I suspect I have a similar problem, but it does not seem exactly the same, so I need to check with the bug reporter (Kees Cook).

When I resume the backlight is set to 0 (it is not switched off, 0 is the lowest value which let me see everything in the screen) and I can higher it using the special key FN+RIGHT_ARROW.

Doesn't crash the machine per-see. As KMS is not enabled by default this is not a regression as yet :). Moving to medium.

I can confirm this problem on a radeon mobility X700.

Offtopic:
sorry for the great amount of posts. Is there any way to make apport-collect upload all relative information in 1 post like in #1 ?

It seems I can now successfully suspend, at least 5 times so far and resume properly, using the following parameters:

Kernel from mainline - 2.6.32-rc7, using parameter "modeset=0"

and

The ATI driver only from the following PPA
https://launchpad.net/~xorg-edgers/+...e/drivers-only

While this has worked for my HP DV8040, with ATI 200m Video card RS480 5955, I do not know if this works for you.

The fix I posted in #34 above, did not work consistently. I have installed the ati and radeon drive from Jaunty. I can now suspend perfectly. So this bug really applied to a version of the ATI driver that is above the one released in Jaunty.

This is true always for me now in Lucid since KMS for ATI is on by default.

I managed to work around this by adding the following lines to grub.
radeon.modeset=0 noapic

After doing this, suspend to ram has worked 100%.

Hi Kees,

This bug was reported against an earlier version of Ubuntu, can you
test if it still occurs on Lucid?

Please note we also provide technical support for older versions of
Ubuntu, but not in the bug tracker. Instead, to raise the issue through
normal support channels, please see:

    http://www.ubuntu.com/support

If you are the original reporter and can still reproduce the issue on
Lucid, please run the following command to refresh the report:

  apport-collect 434956

If you are not the original reporter, please file a new bug report, so
we can work with you as the original reporter instead (you can reference
bug 434956 in your report if you think it may be related):

  ubuntu-bug xorg

If by chance you can no longer reproduce the issue on Lucid or if you
feel it is no longer relevant, please mark the bug report 'Fix Released'
or 'Invalid' as appropriate, at the following URL:

  https://bugs.launchpad.net/ubuntu/+bug/434956

Hello. This is still an issue in Maverick. Adding radeon.modeset=0 solves the problem.

Not sure if mine is exactly the same issue:

Maverick 64 bit, ATI graphics card

Suspend and hibernate worked on 10.04. Following upgrade (clean install) failed to resume from suspend and hibernate. pm-log indicated success, computer powers up, but display is blank.

Could successfully suspend/hibernate and resume from recovery console using pm-suspend/hibernate.

Adding radeon.modeset=0 meant that suspend and resume now work.... But this messed up my dual monitor configuration and had to create xorg.conf file.

This bug was filed against a series that is no longer supported and so is being marked as Won't Fix. If this issue still exists in a supported series, please file a new bug.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

This bug affects Ubuntu 10.10, Maverick Meerkat. Maverick has reached end-of-life and is no longer supported, so I am closing the bugtask for Maverick. Please upgrade to a newer version of Ubuntu.
More information here: https://lists.ubuntu.com/archives/ubuntu-announce/2012-April/000158.html

This bug is still in Precise Pangolin.

Declined for Lucid Desktop as EOL.

Kees Cook, 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 xserver-xorg-video-ati REPLACE-WITH-BUG-NUMBER

Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful.

Thank you for your understanding.
