The secondary display resolution is lost on Plasma on current
by coltfire from LinuxQuestions.org on (#5FXKY)
Hi
I am using current with KDE Plasma.
I have a laptop with two displays attached:
1) ASUS vz279he connected with HDMI (Main display)
2) DELL u2312hm connected with USB-C adapter to DVI
At the boot time both displays have 1920x1080 resolution and that what I use.
But after some period of inactivity (and power manager shuts both of the displays),
the second display (DELL), while turns on, looses it's resolution and the KDE display manager
shows only 1280x1024 available.
The ASUS display resolution stays fine.
Any suggestions?
