[Bug 668694] New: Broken screen brightness on openSUSE 11.4, Acer 4810T
https://bugzilla.novell.com/show_bug.cgi?id=668694 https://bugzilla.novell.com/show_bug.cgi?id=668694#c0 Summary: Broken screen brightness on openSUSE 11.4, Acer 4810T Classification: openSUSE Product: openSUSE 11.4 Version: Milestone 6 of 6 Platform: i686 OS/Version: SuSE Other Status: NEW Severity: Major Priority: P5 - None Component: Basesystem AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: bummmm@mailinator.com QAContact: qa@suse.de Depends on: 668691 Found By: --- Blocker: --- +++ This bug was initially created as a clone of Bug #668691 +++ Created an attachment (id=411587) --> (http://bugzilla.novell.com/attachment.cgi?id=411587) hwinfo User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US) AppleWebKit/534.10 (KHTML, like Gecko) Chrome/8.0.552.215 Safari/534.10 Hi, I am testing openSUSE 11.4 on an Acer 4810T laptop. I will attach hwinfo. Screen brightness is broken. The KDE power management widget in the taskbar has a screen brightness slider, which does not change the brightness. Likewise, the KDE power management settings should dim the screen when power is disconnected, but this also is broken. And worse, when I manually change the brightness with Fn+Arrow Right/Left, the brightness changes, but it results in a laggy, unresponsive system. In my most recent test, the mouse kept moving but I couldn't click on anything after changing the brightness this way. Basically the same problem exists on this system with openSUSE 11.3 too. Thanks for your help!

Basically the same problem exists on this system with openSUSE 11.3 too. Did it ever work as expected?
Does the video.ko kernel driver give you a backlight directory in sys?: find /sys |grep backlight ? Please try: acpi_backlight=vendor boot parameter and make sure acer-wmi kernel driver gets loaded.

Please try: acpi_backlight=vendor boot parameter and make sure acer-wmi kernel driver gets loaded. Does this help? Nope, the Fn+arrow keys do nothing when I boot with acpi_backlight=vendor. The acer-wmi module is being loaded correctly.
Thanks very much for any help you can give me with this. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
