The above post helped me to set backlight dimmer on my Asus EEEPC 1101HA, running ubuntu 12.04. But the commands have to be changed somewhat to actually change the file /sys/class/backlight/psb-bl/brightness
2) chmod 666 /sys/class/backlight/psb-bl/brightness to give yourself permission to read/write (711 actually only gives execute permission) 3) Using a text editor (I use vi) gives Fsync errors (/sys is not a normal filesystem), so use the shell to write to the "file" instead: First choose the number, for example 50. The command is: echo 50 >| /sys/class/backlight/psb-bl/brightness 4) done. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/429942 Title: ASUS 1101HA brightness hotkeys don't work, generate ACPI errors To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/acpi-support/+bug/429942/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
