What happens if you go to Settings > Power > and set Automatic brightness to off? This is just to help isolate the problem. Tried to disable automatic brightness when idle (only option I have here), does the same behavior. Btw, now running stock Fedora Kernel 4.4.6-300.fc23.x86_64 so I guess there's no relationship between this and the brightness changes. Just observed some more behavior: After a while, the brightness stopped changing itself. A half hour later, my battery was about 15% so I plugged the AC adapter. On plugging the power supply, the brightness began changing itself again for a while, so the problem is definitly energy saving related. This message is a reminder that Fedora 23 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 23. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '23'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 23 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed. |
Created attachment 1128940 [details] The part of journalctl that matters Description of problem: I'm running Fedora 23 with a new skylake laptop (HM170 chipset). Laptop bios and Fedora are up-to-date. In order to get Intel HD 530 Graphics acceleration working, I had to switch to a newer kernel which is 4.4.2-300.vanilla.knurd.1.fc23.x86_64 found on fedora's thl repository. I'm running without kernel options, but disabled cstates in bios because linux couldn't boot. Now every few minutes, gnome3 shoes the backlight control (the small square that appears when you would change backlight intensity), and indeed the intensity modifies. This isn't a keyboard issue, the brightness just changes itself. I've checked in journalctl and indeed the backlight log is there. Attached files are journalctl part, dmesg and glxinfo.
