This works for me, so maybe it's a specific hardware problem? It may well be a driver (or at least something below GNOME) issue. Any idea how to debug this any further? Command line tools etc? All I can say that this used to work in 11.0 on the same hardware... Michael: can you play in a shell with files in /sys/class/backlight? Actually, no, I can't... there's nothing inside /sys/class/backlight :( So... that sounds like an issue with whatever is supposed to provide this (a kernel module?). Let's move to the kernel... I just booted the Ubuntu 8.10 live cd and it works fine there... I have acpi_video0 and acpi_video1 inside /sys/class/backlight Ubuntu uses the following kernel/driver versions: kernel 2.6.27.11 xorg-video-intel 2.4.1 So this is not very different from current openSUSE... maybe a (auto-)config problem in SuSE? openSUSE 11.1 uses following kernel 2.6.27.7-9 This bug is a duplicate of bug #451024 . *** This bug has been marked as a duplicate of bug 451024 *** |
