tring to edit brightness
- by Martin Mobbs
i'm tring to edit the /sys/class/backlight/max_brightness file to stop ubuntu 12 returning to maximum brightness on each reboot.
gedit won't save the file after i have modified it i have used chown to change ownership to me which was successful.
I then changed gedits settings so it won't save a backup but it still won't save.
It returns with this error,
Could not save the file /sys/class/backlight/acpi_video0/max_brightness.
Unexpected error: Error writing to file: Input/output error
is this yet another bug?
