I'm trying to change/set the default brightness settings which are found in /sys/class/backlight/acpi_video0 (I think this is the correct place for that). Whenever I try to save any of the values though, I am unable to save them (even though I am sudo). Some instances, it complains about not being able to save a backup, other instances it just refuses to save.<br /> <br /> Why is this? <br /> <br /> I'm trying to edit them with sudo and gedit (if it makes a difference).<br /> <br /> Thanks. http://www.linuxformat.com/forums/viewtopic.php?p=106467#106467 leke Wed Jun 20, 2012 11:33 am http://www.linuxformat.com/forums/viewtopic.php?p=106467#106467
