XFCE screen brightness level changes at every login
Hello, A little severity issue to report regarding the XFCE desktop. Every time I login to my desktop the brightness is usually too intense then I adjust it by the XFCE power settings, hoping it holds the setting, but then it reset at next reboot. Wonder if there is a configuration file to set which cannot get rewrote by XFCE settings in order to keep the last brightness level I chose. Thanks and BR, -- Marco Calistri Build: openSUSE Tumbleweed 20210106 Kernel:5.10.4-1-default Desktop: XFCE (4.14.2)

I am not sure but it could be related to what I have reported here: https://bugzilla.opensuse.org/show_bug.cgi?id=1180591 Cheers, -- Maurizio Galli Xfce Team https://en.opensuse.org/Portal:Xfce

Ciao Mau, My case is different because brightness is adjustable as I wish, the only problem is that it does not maintain the same level when you reboot, in this case it always jump to higher brightness.

Hi Marco, try setting the this boot parameter in /etc/default/grub or via YaST: i915.enable_dpcd_backlight=0 I could not find anything specific to your Lenovo model but this helped with other models. So maybe it works with yours as well. Cheers, vinz.

Hello Vinz, Mau! I sorted out this issue just by following the suggestions reported by by Takashi Iwai from the bugreport: https://bugzilla.opensuse.org/show_bug.cgi?id=1180591 This was my previous setting: cat /sys/class/backlight/intel_backlight/brightness 4882 This is the value I put: echo -n 400 > /sys/class/backlight/intel_backlight/brightness I rebooted and brightness now stays at the right level!

This was my previous setting:

Hello! Vinz, I have applied your suggestion now because after some time I noticed that the value into /sys/class/backlight/intel_backlight/brightness get restored at default 4882! Now I'm using the string: i915.enable_dpcd_backlight=0 in my /etc/default/grub and so far so good!
