How to keep display always on

#1

Dear All,

Does someone know how to keep display always on for Debian 17.04 (or later)?
In recent version, display will be blank after 10 minutes.

[ 2284.679853] msm 1a00000.mdss: vblank time out, crtc=0 [ 2284.739865] msm 1a00000.mdss: vblank time out, crtc=0

I also tried to do the commands below, but all are invalid.

setterm --powersave off --blank 0
xset s off

Thanks!

Daniel

Answer by myself.

The screen timeout can be configured via XScreenSaver.

apt-get install xscreensaver

You can configure by running xscreensaver-demo

Once you set Mode to “Disable Screen Saver”, display can keep always ON perfectly.
