My DisplayPort monitor sometimes will not wake after wake from spleep, but when in text mode its works fine

Ask Fedora

I have three monitors. One connected by HDMI, one DVI, and one DisplayPort.

When I wake my computer from sleep the DisplayPort monitor will not always wake or has a delay before getting signal. Sometimes I have to restart the graphical environment to get it to come on.

If I switch to TTY then all three work fine. And if I shutdown my computer, when I turn it back on the DisplayPort monitor is the first to get signal and this happens almost instantly after I turn my PC on. So this is not a hardware problem.

It would look like the graphical environment is not prioritizing DisplayPort and this is causing the delay that sometimes prevents it from working. What would be causing this.

I have a NVIDIA card with the RMP driver.

The DisplayPort monitor is an ASUS gaming monitor, The HDMI one is a normal 60HZ BenQ, and the DVI is a square Lenovo that I was given.

I am on Fedora 42 Xfce. Could this be a driver problem, Xorg problem, or lightDM ?

Please note that I have not had this problem with TTY just graphical.

You mean the text console reached by Ctrl-Alt-F3?
In that case I assume that the Xfce window manager will not handle the wake up. Are there any error logs when Xfce is in charge of the screen and the wake up happens?

What is RMP?

Sorry RPM*

Yes the text console.

The problem should not be with the Xfce window manager. Before I put my PC to sleep I logout then suspend from the lightdm greeter. When I wake up my PC the greeter will display on my other two monitors but the DP monitor will not show anything until after I login and sometimes it wont even do that. But if I do Ctrl-Alt-F2 or F3 then all will have a display. And then I can go back with Ctrl-Alt-F1 and The DP monitor will not have signal.

If I turn off my PC and turn it back on then there is no problem as the DP monitor is the first monitor to get signal.

Check the Xfce logs. I would think it’s the most likely cause of problem as the Windows Manager is in charge of the display state.

There is only one log file related to Xfce and it contains this after I log in.

libxfce4windowing-Message: 13:09:14.650: Failed to fetch _NET_NUMBER_OF_DESKTOPS; assuming 1

However, pleas recall that I log out before putting my computer to sleep. There are no Xfce processes running only the lightdm greeter. I checked in /var/log and found the Xorg log file, but the only ting of intrest that I saw was this.

I dont know if any of that is relevent. It looks like the problem is being related to the driver witch would make sense. Today when I woke my computer the greeter only displayed on two monitors, but after I logged in the desktop environment displayed on all three.

Here is some more from the log.

Update: The problem is infact with lightdm greeter, but after i updated the driver I no longer have the memory leak bug with the window manager so I dont have to log out anymore and dont have the deal with the problem now.
