You dock out the notebook. Then your brightness is set to minimum (the screen is nearly unreadable) and the brightness control is broken - you can't adjust the brightness. When you dock the notebook back in, the brightness is restored to the normal level and you can control it. If you start your notebook outside of the docking station, this bug is not experienced at all (even if you dock in and dock out, everything works). This is a regression with kernel-3.13.2-200.fc20.x86_64 , if I boot kernel-3.12.9-301.fc20.x86_64 then everything works OK. I have this confirmed on Thinkpad X220: 00:02.0 VGA compatible controller [0300]: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0126] (rev 09) and also on Thinkpad T520. I guess both use Intel HD 3000? I don't see anything useful in the logs. I attach journal snippet when I undock the notebook. You can see brightness-related systemd printouts, that's when I try to change the brightness (or some of that happens automatically during docking out).

If you adjust the brightness in any manner, do the values of brightness/actual_brightness in /sys/class/backlight/acpi_video0 and/or /sys/class/backlight/intel_backlight change?

[Bug 1308674] Re: [Lenovo ThinkPad X220] kernel 3.13 i915 brightness settings broken when going from docked - undocked
I've a X220 with 14.04 and I'm facing the above problem aswell. In my setup I do have a docking station with an external monitor hooked up. Undocking my notebook darkens the notebook screen. Docking it again gives normal brightness and undocking again gives again regular brightness. So the problem occuse only the first time of undocking. A solution would be great.

[Bug 1308674] Re: [Lenovo ThinkPad X220] kernel 3.13 i915 brightness settings broken when going from docked - undocked
I just tried this with kernel 3.13.0-34.60 and I'm still experiencing the problem. Brightness set to minimum and not adjustable after undocking. I originally encountered another (duplicate?) bug post which suggested to upgrade the x220's BIOS, so I'm also running the latest BIOS version (8DET69WW / 1.39).

I can add that docking and undocking again re-enables brightness adjustment. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1308674 Title: [Lenovo ThinkPad X220] kernel 3.13 i915 brightness settings broken when going from docked - undocked To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1308674/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Daniel Hahler, thanks for the update on your issue. As per the Ubuntu Kernel Team, for linux (Ubuntu) bug reports, one would would mark this bug Triaged when the original reporter has tested this to the mainline kernel. As well, the OR would want to provide as much information, for example check for a WORKAROUND, if BIOS has a hand update it, regression bisect, etc. Given that your issue is resolved, let us wait for input from the OR. ** Changed in: linux (Ubuntu) Status: Triaged = Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1308674 Title: [Lenovo ThinkPad X220] kernel 3.13 i915 brightness settings broken when going from docked - undocked To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1308674/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
