--- Comment #6 from Adrien (ker...@asdrip.fr) --- Thank you for your response. With 6.1.3 "ls /sys/class/backlight" returns amdgpu_bl0. Output of "cat /proc/cmdline" returns BOOT_IMAGE=/boot/vmlinuz-linux root=UUID=7d604fa9-81a1-4cbc-ae1d-8brfe544148b rw quiet loglevel=3 splash vt.global_cursor_default=0 resume=UUID=e40cbf4e-5477-4ecb-b1f1-bd8d5890f507 audit=0 nvme_load=yes sysrq_always_enabled=1 mem_sleep_default=deep in 6.1.4 **after** I deleted the "acpi_backlight=vendor" I had. Thank you, dropping acpi_backlight=vendor do bring back amdgpu_bl0 to /sys/class/backlight. However, dmesg now shows "acer_wmi: Unknown function number - 4 - 0" every time the brightness change key are touched, but it does not seem to have any effect (brightness do change) but to spam the log. I don't know if the issue is really related to walter59. -- You may reply to this email to add a comment.
