Fedora 38 external HDMI monitor freezing

cnmirose · October 3, 2023, 5:12am

Hi Folks,

I have a lenovo laptop running fedora 38. I use KDE under X11. I’ve got the nvidia drivers installed so the monitor is recognized (this was an initial problem with only the nouveau driver).

HOWEVER: the external (HDMI) monitor freezes – reliably, not intermittently. The usual etiology is

move mouse all around between monitors (works fine)
grab window to move it to monitor
glitchlette on grab
start moving window to other monitor
nada shows up
mouse now doesn’t show up either (monitor frozen)

This can be reset by futzing with the display/monitor control in the gui control panel, but that fix does not last. I tried a few different monitors (LGE and two samsungs). The LGE freezes immediately, the Samsungs put up a good fight, but still freeze eventually (measured in minutes).

And here are two cutenesses:

none of this seems to happen using KDE under Wayland. (but I prefer X11 because Wayland seems to have latency issues with certain window operations).
if I disable the laptop screen and attempt to use only the monitor, the lag gets STOOPID – basically unusable. (I did this only once on a lark).

Does any of this sound familiar? Has anyone found a solid fix? I HAVE seen similar monitor freezing threads, but no resolution as yet.

I’ll post system info to the cognoscenti as appropriate.

Cheers,

Chris

have to ask, but do you have external monitor connected when you boot up and log in?

i mean i had also black screens and freeze when i boot up connected on external. If i boot and log in without external monitor all works fine.

No not in general (connect AFTER boot). But I did just tonight try on boot. Same behavior. And I’m having NO problem booting (so far ). The ONLY problem is the freezing external monitor under X11 – which hints at a deeper problem I suspect. And that suggestion about shutting down the laptop screen was a great one since it showed TRULY outre behavior on the external monitor – didn’t freeze, but the lag became ridiculous. So there’s something going on above my basic user paygrade.

The laptop apparently has dual gpu with nvidia as the dGPU.

I have found that there is one config file that is provided when installing the nvidia drivers from rpmfusion that may aid in your symptoms on xorg.
The file /usr/share/X11/xorg.conf.d/nvidia.conf could be copied to be /etc/X11/xorg.conf.d/nvidia.conf, then reboot and log in with xorg. It makes a bit of change in managing the external monitor port and for me has always worked. I have never had the persistent gui problems you describe but it may assist in your case.

This also may be related to the particular nvidia gpu in your laptop. Please post the output of inxi -Fzxx and dnf list installed \*nvidia\* so we can see the full details

Thanks so much, Jeff!

I’ll in the meantime futz around in /usr/share/X11 and /etc/ as you suggest and see what I see.

Thanks again!

Oh, and I was using Wayland Above. Here’s inxi -Fxzz under X11. Both this and above were (obviously ) with monitor attached (a Samsung TV). NOTE: I upped the pixel count using the display-control gui (control panel).

UPDATE:

HEY JEFF!!!

While I’m reluctant to do a premature happy dance, copying the nvidia.conf file from /usr/share/… to /etc/X11/xorg.conf.d SEEMS TO HAVE WORKED!

NO glitchlette on window grab
NO freezing

I’ll keep playing around, but the behavior is DISTINCTLY different.

And I’d have NEVER figured this out on my own. If this is indeed a happy dance moment, is there a way to promulgate this info in a coherent way to the fedora/Xorg squad?

Cheers,

Chris

UPDATE II:
Sigh, no joy. lasted longer than ever before but ultimately froze. That said, no window-grab glitchlette!

By the way,
If you use the </> button it provides preformatted text tags and retains the screen formatting of what you post. As you can see the block quote button " does not retain the formatting.
