I've fixed the brightness bug by removing the video module. I.e. I inserted the following line in /etc/modprobe.d/blacklist and rebooted my laptop: blacklist video
This is a trial-and-error workaround, I don't know if it's a good thing to remove this module or not, I just know that it fixes the bug in my laptop. P.s. you may use the following one-liner: while cat /sys/class/backlight/acer-wmi/actual_brightness; do sleep 0.1; done to see the brightness value, while pressing the brightness keys: a) Increasing two by two, before removing the module, b) Increasing one by one, after removing the module So now I think absolutely everything is working OK with Acer Aspire 5920G, I don't think I have any problem at all. Charlie, can you send me the forum topic link? I can't find it... :) -- Acer Aspire 5920G Fn keys not working correctly https://bugs.launchpad.net/bugs/281951 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
