Acer B326HK – not finding a signal when the linux host wakes up out of sleep
Posted by jpluimers on 2018/07/02
Problem:
6 unlabeled buttons: I can not force the input to display port and monitor is searching other ports when host is sleeping. Getting no output when I wake up the host. 😞
Btw, this is for an Acer B326HK monitor. Other than issues with the UI, seems like a decent 4k monitor.
Solution:
my mistake was to use Display Port (Choice was DP or DVI) and the workaround is to disable power state changes on Display Port with something like “
xset -dpms“
