Marten, you might want to try something like this in your /etc/rc.local: brt=`cat /sys/devices/virtual/backlight/mbp_backlight/brightness` abrt=`cat /sys/devices/virtual/backlight/mbp_backlight/actual_brightness` logger -t rc.local "brightness was $brt , actual_brightness was $abrt" if [ "$brt" != "$abrt" ] ; then echo $abrt > /sys/devices/virtual/backlight/mbp_backlight/brightness afterbrt=`cat /sys/devices/virtual/backlight/mbp_backlight/brightness` logger -t rc.local "changed brightness to $afterbrt and actual_brightness is $abrt" else afterbrt=`cat /sys/devices/virtual/backlight/mbp_backlight/brightness` logger -t rc.local "no brightness change needed, brightness is $afterbrt and actual is $abrt" fi
This should give you a log entry in /var/log/messages that will show some helpful information when /etc/rc.local executes. So, after booting, check the log with: $ grep bright /var/log/messages and see what happened during boot. It seems like you could have a different problem since your /sys/ entry is different than ours. Take a look in /proc/ to see if you have any more places where brightness is set or shown: find /proc/ -iname '*bright*' hth -- display is fully dimmed after resume from suspend https://bugs.launchpad.net/bugs/451282 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
