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,
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!
Best regards,
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!
