Double sized after resuming from suspend.

Post by hans123 » Fri Aug 10, 2018 5:31 am

After resuming from suspend om my LM 19 Mate 1.20.1 system the HiDPI screen shows the desktop double sized sometimes / half of the time. To get it right I have to log out and back in. This is with a NVidia GT1030 graphics card and with the NVidia propr. driver 390.48-0ubuntu3 and also with the Nouveau driver 1:1.015-2

In this forum a similar situation was resolved a while ago with a new Linux kernel version. Is there something I can do / investigate to fix the resume error?

Thanks.

I thought this was: Solved / Fixed by a change in the BIOS: in the Power Mgt - section, ErP was Enabled now Disabled. This relates to S5 (shutdown) state.
But, alas, it is not. I have tried many things, the current state (seems to be): On resolution 3840 * 2160 resume works fine. With HiDPI set via Preferences / General in Cinnamon, resume results in a black screen. SSH into this machine is the nezt step to test ...
