Unloading or loading it does absolutely nothing (/sys/class/backlight is always empty). I've only found in dmesg: [ 8.670586] video: probe of LNXVIDEO:00 failed with error -5 When un/loading the video module, there is further no such message. It is only in dmesg's history. * The 'acpi_osi=Linux' kernel option seems to have no effect * The 'acpi_backlight=vendor' leaves the brightness at bootloader level and cannot change the brightness further in booted system * The 'acpi_backlight=legacy' restores the default 12.2b2 behaviour: it dims backlight to minimum during boot and leaves it at that level. Cannot change it further. Need to poweroff and increase the brightness when in bootloader. Plain reboot doesn't help - brightness is not adjustable even in bootloader. Note: I tried this all after upgrading to 3.4.4-2-desktop SMP PREEMPT x86_64 In 11.3, /var/log/messages I have only (after wakeup): [ 1529.359389] video LNXVIDEO:00: Restoring backlight state Looks like some problem in acpi/video for me. At least the dimming did work, once at boot. I'll now try RC1, but I doubt anything changes there. -- 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.
