[Bug 680822] New: openSUSE 11.4 Intel 4500MHD screen brightness slightly dim and not easily changeable
https://bugzilla.novell.com/show_bug.cgi?id=680822 https://bugzilla.novell.com/show_bug.cgi?id=680822#c0 Summary: openSUSE 11.4 Intel 4500MHD screen brightness slightly dim and not easily changeable Classification: openSUSE Product: openSUSE 11.4 Version: Final Platform: i686 OS/Version: SuSE Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel AssignedTo: kernel-maintainers@forge.provo.novell.com ReportedBy: bummmm@mailinator.com QAContact: qa@suse.de Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; Linux i686; rv:2.0b12) Gecko/20110222 Firefox/4.0b12 Hi, I have an Acer 4810T laptop with Intel 4500MHD graphics running openSUSE 11.4 KDE. I used to run 11.3 for the full 8 months. There is a new bug introduced with 11.4 that makes the screen brightness be slightly dimmer than maximum. It starts off in the first stage of KMS during the bootup, the lizard splash screen appears full brightness in the wrong resolution, then after a few seconds the screen flashes and the lizard appears again with the correct widescreen resolution. At this point the brightness dims slightly. And it it remains that way all the way into the KDE desktop. This is more irritating because the brightness can not be easily changed due to bug #668694. But I have been using the setpci screen brightness workaround. However it constantly reverts back to the slightly dimmer level. After resuming from DPMS power saving, it reverts to a dimmer level, and the same when resuming from suspend. There is a solution: Install kernel 2.6.38 from the kernel repo, and it behaves the same as the 11.3 kernel which didn't have the bug. Thanks for looking into this.

Install kernel 2.6.38 from the kernel repo Rui/Matthew: Do you eventually have an idea which patch came in between 2.6.37 and 2.6.38 fixing this (which might even be worth to submit it to stable@)?
