Issue

When the displays go to sleep and wake back up, the scaling is turned back to 100% and the window id resized wich makes it really hard to read on a hidipi 27.5 Samsung screen.

Steps to reproduce

1. let the system go to sleep
2. wake up the system
3. there it is! Everything is so tiny...

Expected behavior

leave the original scaling ratio settings as it was (and all other settings) at 175%.

Other information

on wake up, if instead of entering my password, I do a 'ALT-CTRL-BACKSPACE', occasionally it will wake up normally, but it is not constant.

Configuration info, if applicable

If this bug report is related to an Applet, Desklet or Extension, please paste (or use a pastebin service) the offending extension's settings, if it has any. You can obtain this by opening its configuration, clicking the 'hamburger' button in the upper-right corner of the window, and selecting "Export to a file". Please be sure to review the contents and remove any personal data it may contain.

I'm experiencing the same issue. If my system comes back from suspend-mode after the lid was closed (notebook), the monitor scale will be reverted to 100% (instead of 125%).

Same as Inrumpo.

My Surface go 2 has the same bug, and I am sure it's caused by the screen saver. (After closing the screen saver, the monitor settings will not change waking from sleep)

Hi.
On my system I have never activated the screensaver while I have lock on sleep and the problem exists although it is not constant.
On my system I have fingerprint login enabled and I have noticed that when I wake up it asks me for the fingerprint the system restarts fine while if it does not ask me for the fingerprint but the password then it forgets the settings.
I hope this will help.

Hi, please take a look at this comment:

linuxmint/cinnamon-screensaver#416 (comment) Thanks

I updated and the issue now sometimes come and sometimes does not.

It resets the multiple screens configurations (including the percentage) upon suspend and resume.

Thanks,

It is worth noting that not only the screens configurations are reset, but also the voice (both input and output) configuration is reset after waking up from sleep.

Regarding the screens configuration:
I noticed that when switching on of the screens off and then on, the last manual configuration is restored. So, currently after every turn on the computer forgot about the manual configuration that I made. Then I switch off then on one of the screens and the configuration that I made is used again.
