MX Linux Forum

Posted: **Tue Sep 27, 2022 6:40 pm**

I'm on a fresh install of MX Linux. I've changed my screen resolution from 3840x2160 to 2560x1440 via xfce4's display tool and I've changed my theme to "MX Dark Thick Borders" with the MX Tweak tool.

If I let my machine idle for about 10 minutes, it'll turn off the screen (as specified by the power settings) but instead of staying off, it will come back on after a short period of time and change the resolution back to 3840x2160. This happens reliably every single time it's idle. If I happen to manually lock the computer by way of the whisker menu, the resolution stays the same.

A possibly related issue is that my theme will sometimes revert to what looks like MX Dark and I suddenly have blue borders around windows. This happens less frequently but I can't figure out what's causing it.

I don't see anything in the logs for either issue. Any ideas as to what's going on? As a workaround I'm going to leave the higher resolution on and try to enable scaling. Thanks!

Here's my quick system info:

A followup: I tried changing the resolution with the MX Tweak tool instead of xfce4's display settings and the same behavior exists with the resolution changing.

This time around my theme appears to have changed as well (I now have blue borders again). I'm not sure if the two issues are related or not.

Some searching online has pointed to screensaver issues causing this but I noticed that the xfce4 interface for screensavers doesn't exist in the settings manager on MX. I'm not sure which package might provide that.

Posted: **Tue Sep 27, 2022 8:17 pm**

debian (and us) don't have xfce4-screensavers installed. so light-locker could be a factor, especially if manually locking the screen doens't produce the issue.

I have switched on my own machine to xscreensaver and removed lightlocker. I have xscreensaver set to lock the screen, which unlike light locker does not affect the actual running session.

I think your likely right and I'll make those changes and reboot the rig tomorrow sometime.

As further evidence of that, I enabled the "Lock screen when system is going to sleep" option in the Power Manager and set the "Automatically lock the session:" option to "When the screensaver is activated". This solved the issue of the resolution changing but I"m unsure if it solved the theming issue because I still have blue borders.

Thank you for the reply!

Another thing that might be happening is that your display manager might be re-detecting the monitor each time you unlock your session. What I would try is (assuming you have Xfce not KDE) go to Settings/Display, click the Advanced tab (after setting it to the correct resolution on the General tab), click the icon to create a new display profile, name it whatever you want, then set it to automatically enable profiles when a new display is connected. From then on it should apply the saved profile including the resolution even if it keeps detecting the monitor whenever you unlock the display.

Some gtk3 apps use client side dectorations and so wouldn’t have window manager borders and some would use the window manager theme.

That makes sense. I've gone ahead and made those changes and I probably should've done that anyway as sometimes I have an additional monitor for this desktop.

I understand that but the blue borders happen to show up across all applications. The entire theme is switched back to "MX Dark" rather than the "MX Dark Thick Borders" I had selected.

I replaced light-locker with xscreensaver, set the former to kick on at 8 minutes of inactivity and the power manager is set to blank after 10 minutes and is still set to "Lock screen when the system is going to sleep". Hoping for the best. I'll report back after a reboot and some idle time to see what happens.

Oddly with the current configuration, the display never seems to go to sleep. Perhaps removing light-locker or setting the xscreensaver time to a shorter duration than the power manager is the issue there?

I really don't care much if the screen locks, I'd just like it to turn off after a period of inactivity. I've set xscreensaver to 10 minutes to match the power manager and I'll see what happens. I didn't experience a resolution change this time, though.

in the xscreensavers settings you can configure the power down time. it kind of takes over some of the display management functions.

here's what I meant about the borders (screenshot). Not all apps will display the thick borders. in the shot, my thunar window has them, but the Appearance app does not. Appearance users gtk3 client side decorations, but thunar does not, so it picks up the window manager decorations.

I'll tinker with xscreensaver's settings some more.

I understand what you're saying about the borders. In my case, thunar does not have blue borders when I have chosen the mx dark thick borders theme from mx tweaks, nor do gtk apps (say for example baobab). After some arbitrary conditions I've not yet experienced, *all* of my windows will have the blue border (except maybe qt applications). I still haven't figured out what's kicking it off. I also didn't have this issue when I was running MX 21.1 or 19. I'm not too worried if I don't ever solve it, though. The borders don't bother me that much.

I really appreciate all the replies. I love this distro and I'm glad I was able to get it running again.
