Hi, I tried the patch today on a Leonvo Z360 running on xubuntu 10.10.
After installing the fix and adding the line acpi_backlight=verdor, I am able to adjust brigthness with the brightness control in the panel. However, the hotkeys don't work (minor issue, I can live with that), but as soon I reduced the brightness once, I can never get back to the original (maximum) brightness, it will always stay dimmer. uname -a Linux Karl 2.6.35-25-generic #44+kamal2~mjgbacklight1-Ubuntu SMP Thu Jan 27 23:45:18 UTC 2011 x86_64 GNU/Linux cat /sys/class/backlight/intel_backlight/max_brightness 4882 Any ideas on how to fix that?
