It seems like hibernates set the actual_brighttness to 0

--- Comment #3 from Takashi Iwai tiwai@suse.com --- AMDGPU can create backlight controls in several different ways, and we need to figure it out at first. Could you try to boot with drm.debug=0x0e, and give the dmesg output?

--- Comment #5 from Takashi Iwai tiwai@suse.com --- Also, for the headphone and the speaker playback, I quickly fiddled with UCM profile.
Below is a totally untested profile. Please expand it under /usr/share/alsa, and restart PA / pipewire.

Created attachment 860941 [details] dmesg output with 0x0e
cat /proc/cmdline BOOT_IMAGE=/boot/vmlinuz-6.0.0-rc1-3.g7bd57d5-default root=UUID=67e5381b-1f65-49ec-9b58-2e392c6b5d9a splash=silent resume=/dev/disk/by-uuid/eeb7aaf9-93ab-4dc2-841a-c09ada050b9f mitigations=auto quiet security=apparmor drm.debug=0x0e
Thanks. This indicated the standard backlight.
Could you test the following? - Boot without drm.debug option, but with amdgpu.backlight=0 option. - Verify whether you can control the backlight - If yes, turn on the debugging echo 0x0e > /sys/module/drm/parameters/debug then go to hibernate. Do resume, and get the dmesg output. Turn off the debug again echo 0x00 > /sys/module/drm/parameters/debug
- If the backlight isn't controlled properly with amdgpu.backlight=0 option, try amdgpu.backlight=1 option instead. Then perform the same procedure as above (debug-on/hibernate/debug-off).
Upload the dmesg output taken in the test above.

The backlight slider works with amdgpu.backlight=0

--- Comment #13 from ted chang monkeyboyted@yahoo.com --- I do not use hibernate so I rarely notice hibernate bugs. I can confirm Tamara is right and it works. Closing this bug report. I do not think I need to post dmesg logs.
