Description Adam Huffman 2007-07-24 18:58:51 EDT
Description of problem: With recent kernels I am at last able to suspend to RAM and resume on a Vaio SZ3XP. However, when I resume the screen is far too dark. Even if I modprobe the sony_laptop module, echo-ing values into /sys/class/backlight/sony/brightness doesn't have any effect. Version-Release number of selected component (if applicable): 184.108.40.206-33.fc7 How reproducible: Every time Steps to Reproduce: 1. Suspend laptop to RAM 2. Resume 3. Actual results: Screen is far too dark and the brightness cannot be increased Expected results: The screen should have normal brightness Additional info: Hardware details are here: http://smolt.fedoraproject.org/show?UUID=50e550b8-d9bc-4262-b41f-75b41faf7e0c

I'm now running rawhide on the Vaio and this problem is still there.

Hello Adam, Thomas, I'm reviewing this bug as part of the kernel bug triage project, an attempt to isolate current bugs in the fedora kernel. http://fedoraproject.org/wiki/KernelBugTriage I am CC'ing myself to this bug and will try and assist you in resolving it if I can. There hasn't been much activity on this bug for a while. Could you tell me if you are still having problems with the latest kernel? If you are, could you try rmmoding the sony_laptop module before suspending and then re-loading on resume and see if this works. If the problem no longer exists then please close this bug or I'll do so in a few days if there is no additional information lodged. Cheers Chris

Hello The last time suspending to RAM worked (which was a week or so ago), the darkened screen problem had been fixed. As of today, I can no longer suspend to RAM, so I can't really confirm it currently.

I'm running rawhide now too (F8T2+) and the problem persists. I think this is a HAL quirks problem. I made a launcher that just does a 'pm-suspend --quirk-vbe-post' and it works fine like that. I've opened a bug for my laptop about this here: https://bugzilla.redhat.com/show_bug.cgi?id=301041

Yes, that does work, so feel free to close this bug. Thanks.
