You can also try to verify sysfs interfaces such as below example $ ls /sys/class/backlight/ intel_backlight $ cd /sys/class/backlight/intel_backlight $ cat max_brightness 12 $echo 12 | sudo tee brightness $echo 6 | sudo tee brightness If this does not change brightness, something is wrong with VGA (or BIOS) brightness interfaces. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1890055 Title: Brightness control does not work with 5.4.0-42.26 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1890055/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1890055] Re: Brightness control does not work with 5.4.0-42.26
Hello, 3 questions here: 1. Can you adjust the screen brightness with the hotkeys? 2. Can you adjust the screen brightness with the slide bar in Settings -> Power? 3. If not, does it work for you with these 2 methods above on older kernels (and which version)?
