--- Comment #2 from Tobias Burnus
a small comment: you should use sysfs to change the brightness and no longer the proc interface.
Actually, I usually simply use the Fn+brighter/darker buttons, which works (8 brightness steps); otherwise I want that kpowersave works. In terms of sysfs I have: /sys/class/backlight/thinkpad_screen/ brightness/actual_brightness (0 to 7, same problems as described above) max_brightness (always 7) /sys/class/backlight/acpi_video0/ actual_brightness brightness max_brightness: always 100 /sys/class/backlight/acpi_video1/ actual_brightness between 20 and 100 - this value actually seems to work -- I get 8 different % values. brightness - remains at 100 [I'm using the Fn-brightness buttons] max_brightness (is 100) Using "echo 50 > brightness", I often end up with actual_brightness = 20; I have to use the command once or twice again to get the desired value. Why does acpi_video1 work and thinkpad_screen does not? -- 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.
