gnome-shell slow when using brightness shortcuts
Whenever I'm in Xorg and make use of fn + f11 / f12 the gnome gets frozen and the brightness goes to the maximum or pussy until I freeze the graphical interface.
with the command:
ls / sys / class / backlight /
get two dell_backlight
and intel_backlight
folders
the services are leaving the boot slow. systemd-analyze critical-chain
systemd-backlight @ backlight: intel_backlight.service @ 1.468s +968>
└─system-systemd \ x2dbacklight.slice @ 1.198s
all distributions with gnome-shell occurs this and there is no solution, many dell notebook users have this problem, I use arch linux on a dell 5548 intel 5500u + amd r7 m265.
thank you.
