I have found a work around for changing the brightness on the Samsung R610. Full brightness was really hard to look at all the time!
1. Press CTRL+ALT+F1 and login (as running the command to change brightness from a Terminal in X does not seem to have any effect) 2. sudo su root (as applying the following command with just sudo results in a permission denied error) 3. echo -n 50 > /proc/acpi/video/NVID/LCD/brightness (to change brightness, where '50' is the brightness value ranging from 40 to 100 as depicted by the result of 'cat /proc/acpi/video/NVID/LCD/brightness') 4. (optionally) exit (to get log out of root terminal) and exit again (to log out of user account) 5. Press CTRL+ALT+F7 (to return to your X session, noting that the change in brightness is maintained when switching back) Hope this helps, people. Unfortunately, due to the need to switch to a root terminal to change the setting, I'm not sure if this functionality can easily be linked to the brightness key presses without more low level changes. You should be able to use this in a start-up script however to make the brightness start at about 50% for example. -- Some hotkeys don't work on Samsung R610 https://bugs.launchpad.net/bugs/356952 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
