I have ASUS 1015CX Netbook on which I have installed Ubuntu 12.04LTS. All seem to work fine however there is an issue with brightness settings; changing the brightness (both through settings and with hotkeys) has no effect.
However once I log off or power down the screen brightness drops to minimal level. I have to log in and out again for the brightness to increase.
How can I fix this?
ls /sys/class/backlight
andcat /sys/class/backlight/*/brightness
to the question. have you installed the proprietary CedarView driver? ASUS 1015CX specs.ls /sys/class/backlight
:acpi_video0 psb-bl
cat/sys/class/backlight/*/brightness
