Screen dim on wake up from suspend
Hey everyone!
I installed antergos on my hp-ac042tu laptop. When I reopen the lid or when I wake the device up from suspension, I get the login screen. After login, the screen is extremely dim and unusable. I tried taking screenshots and they seemed to be at normal brightness when I checked later i.e. after rebooting the computer.
How do I fix this?
Use xbacklight to set the brightness of your screen (e.g. try the command: xbacklight -set 60), if it works you can create a script in /etc/pm/sleep.d/ so that it’s automatically executed when resuming:
sudo gedit /etc/pm/sleep.d/99-set-backlight.sh
with this content:
#!/bin/sh
case “$1” in
resume|thaw)
export DISPLAY=:0
xbacklight -set 60
esac
