Description Tommy He 2010-03-09 19:11:10 EST
Created attachment 398970 [details] dmesg information Description of problem: Version-Release number of selected component (if applicable): gnome-power-manager-2.29.2-1.fc13 How reproducible: Steps to Reproduce: 1. Start GNOME DE. 2. Close the lid of the laptop. It goes into suspend automatically without problem. 3. Open the lid and resume the laptop. Actual results: The LCD panel is dim and there is no way to adjust the brightness. No slider in gnome-power-preference. Gnome-panel brightness applet says 'unable to acquire the brightness of the laptop'. Keyboard shortcuts do not work, either. Logout or restart make no difference. Expected results: Automatically restore to the previous brightness after resume. A slider in gnome-power-preference to adjust the brightness. Applet and keyboard work. Additional info: The problem persists no matter I use nvidia binary driver 195.36.08 from rpmfusion or nouveau gallium3d. Running the same nvidia binary driver on Fedora 12 does not have this issue. Smolts: http://www.smolts.org/client/show/pub_0b8133aa-815e-4c11-9e5f-f5ca20f88bb6 The only way I can adjust the brightness is to use a Fedora 12 LiveCD.
Comment 1 Tommy He 2010-03-09 19:52:21 EST
Fedora 13 Alpha LiveCD KDE spin does not have this issue while GNOME spin has. Both running on the same laptop with nouveau driver. So I assume it would be a gnome-power-manager problem.
Comment 2 Tommy He 2010-03-09 20:35:04 EST
Switching to KDE DE gives me the ability to adjust the brightness again. Tested on the same laptop with nvidia binary 195.36.08 driver.

same problem here on dell inspiron 1755 - and happens even before suspend/resume (ie unable to change screen brightness in gnome, kde works ok). fedora 13 installed from alpha rc4 live, + all updates video is 01:00.0 VGA compatible controller: ATI Technologies Inc M92 LP [Mobility Radeon HD 4300 Series]
Comment 5 Nigel Jones 2010-03-11 15:16:46 EST
Same problem here too Chipset: "ATI Mobility Radeon HD 3650" (ChipID = 0x 9591) Occurs with KMS off and on.
Comment 6 Nigel Jones 2010-03-11 15:17:23 EST
Workaround is echo 15 > /sys/devices/virtual/backlight/acpi_video0/brightness or similar

Please see bug 572896 and test the scratch build referenced there (x86_64 only). If it works, close this bug as a duplicate of 572896. Thanks.

Alright, I see that Tommy He uses i686, so I've now started an i686 scratch build too: http://koji.fedoraproject.org/koji/taskinfo?taskID=2048407

(In reply to comment #10) > > Sadly, it does not work with :-) > > http://koji.fedoraproject.org/koji/buildinfo?buildID=161370 I know. That's gnome-power-manager-2.29.91-2.fc13 which is known to have the bug. > (In reply to comment #9) > > Alright, I see that Tommy He uses i686, so I've now started an i686 scratch > > build too: > > http://koji.fedoraproject.org/koji/taskinfo?taskID=2048407 But what about this scratch build instead? From your comment I did not quite understand whether you tried it or not.

From your comment I did not quite > understand whether you tried it or not. Sorry, my fault. I did not notice the m1 tag. I thought it was the one I tested yesterday. Yes, the scratch build works. I am going to close this bug.
