It's a new bug, there are some reports like bug #140839 and bug #140572, and probably bug #117327.
In my case, this time g-p-m is using 6 as the unit to add/subtract to current brightness level. According to acpi, my brightness possible levels are: 12 24 36 48 60 72 84 100. So, if I'm at 100, then g-p-m subtract 6 and sets 94, I end up at 84 (the next level below), but when g-p-m adds 6 to 84 and sets 90, I'm still at 84, since I need 100 to be at the next level. -- gutsy: g-p-m 2.19.6-0ubuntu4 breaks brightness control https://bugs.launchpad.net/bugs/136346 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
