This bug is awaiting verification that the linux-oem-6.11/6.11.0-1010.10 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-noble-linux-oem-6.11' to 'verification-done- noble-linux-oem-6.11'. If the problem still exists, change the tag 'verification-needed-noble-linux-oem-6.11' to 'verification-failed- noble-linux-oem-6.11'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

Login to a system to console mode, set brightness to 5% (light -S 5 or direct in sysfs), run compositor from command line. Screen brightness go up. 2. Turn brigtness down to 5% in wayfire screen, switch to text console and back to wayfire - again screen brightness goes up. 3. Turn brightness to 5% in wayfire and then screen blanks at idle. Touch key or mouse - screen again runs on the much higher brightness. In all cases in the /sys/class/backlight/amdgpu_bl0 directory brightness keep the value I set (5%) - but the actual brightness is different. So system somehpw ignores the value in brightness and not setting actual brightness the same but fill it with some default. == Proposed fix https://github.com/torvalds/linux/commit/4f26c95ffc21a91281429ed60180619bae19ae92 (in v6.12-rc7, and d83c747a1225d as in v6.11.8) To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/2090789/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
