Another Display Issue

wstapl · 8 July 2021 17:24

Like the topic says I am having a Display issue, but I think mine is bit more unique, if this is a duplicate please kindly post the duplicate.

I am new to Garuda Linux, and Arch Based Linux. I come from a headless Debian based background so displays is something I never deal with.

Firstly, the display was working. I have 4 displays in total. 3, 1920x1080 displays and 1, 2K display, the 2K display being the trouble. I just installed some programs the only anomaly programs I can think of installing was snap, otherwise everything else was in the AUR like chrome, or an App Image Lychee, Prusa Slicers. I had rebooted the system fine, but when it went to sleep and I woke it up my 2k display didn't turn on.

However it would load the Grub and show the Kernel launch, and even the splash screen. However as soon as the desktop load, the display turns off, If I shutdown, during the final stage of shutdown will the display turn on just to turn back off when the system stops.

When I unplug and plug in the display. The display manager sees that there is something, and says "A new output has been added" the display manager flickers, like when you make a change and applying, but the display still doesn't show up.

I tried load an old snap from before I installed of my programs, no dice. As well tried a different display manager, nothing.

I do see a fault in the journal, but not sure what to make of it and google seems to show that error being all over the place.

This looks like a nvidia bug (search for this).
Have you tried management with nvidia utilities? What happens?

Did you try changing output ports (HW)?

Check in Xorg logs for useful messages to “what happens and the monitor gets vanished?”.

In linux, we call SDDM, GDM as Display Managers. What do you mean exactly? Which DMs have you tested and how do they fail? Did you try restarting them?

Also, try using less monitors, but keep the broken one (2k) in the active ones.

Try enabling scenarios using xrandr commands.

Compare logs/errors from different troubleshooting procedures.

Ask nvidia support about this.

After messing with cables and un-plugging and plugging back in the displays. I did at one point get a prompt which looks like a prompt you would get for a disabling a projector, or laptop screen, perhaps? Not sure what that menu is called for Garuda.
Anyways, with that menu I was able to activate the 2K display once more, with one of the display disconnected. As soon as I plugged the other display back in, the 2K display shut back off, but I was now able to go into the display settings and saw the monitor was disabled in my display drop down options. I was able to enable the monitor, and it turned back on but It still didn't show in the monitor layout, and the screens layout was all messed up.
I closed the Display Settings and opened it back up and the 2K display was finally there in the monitor layout, once I re-positioned the displays and applying it I finally got it back to the state it was.

I have tried re-creating the issue to figure out why it happened, but have yet to do so at this point. System has went to sleep multiple times without issue and display is working as expected.

So with that I do have a couple questions:

What is that menu that pops up to disable screens?
Why did rolling back to a prior Snap using Timeshift not revert any potential settings that my have caused this? I am NOT including Home Directories.
Any reason that it wouldn't show up in the Display Settings if it was just disabled?

I will be willing to try to re-create the problem again, but need a bit more information here.

It’s Plasma Display utility, for this exact point, adding and configuring newly added monitors.

Because your issue is related to $HOME configuration files.

Possibly because of new settings not refreshed properly in the app, or the app was open when doing these changes.

Hey that happens to me when there is a powercut to second display and I disable it manually or through start+p when system is running after that if u don't enable it and shutdown pc next time when u switch on it can no longer see the monitor it even happens in windows 11 and then u have to replug the monitor . Note I have only one external monitor and I use laptop
