Update - if I suspend/resume AFTER modifying /proc/.../LCD/brightness directly, the display brightness is not dimmed after resume.
HOWEVER, if I unplug AC power and then plug back in, the brightness reverts to the dimmed value. For example, this is after resume (with a previously modified /proc/.../brightness): <PROMPT>$ cat /proc/acpi/video/VGA/LCD/brightness levels: 20 24 29 36 44 53 63 76 100 current: 100 AC adapter unplugged: <PROMPT>$ cat /proc/acpi/video/VGA/LCD/brightness levels: 20 24 29 36 44 53 63 76 100 current: 29 AC adapter plugged in: <PROMPT>$ cat /proc/acpi/video/VGA/LCD/brightness levels: 20 24 29 36 44 53 63 76 100 current: 44 -- Screen Dimmed After Resume https://bugs.launchpad.net/bugs/409664 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
