XFCE Freezes entire Pi 4b when using Remote Desktop? (Issue Identified)

johntdavis84 · 13 August 2021 23:47

EDIT 3 (Saturday, August 14, 2021 @ 11:59 pm US Central): So, I’ve made a bit of progress. tl;dr via VNC, I’ve been sitting at the login screen (LightDM with default greeter) for at least 10 minutes. Pi has yet to freeze. I’ve got Qtile installed, but not configured. I’m going to try logging in to that and see if I get the same issue. If I don’t, I’ll just write this off as a corrupted XFCE settings issue.

EDIT 4 (Sunday, August 15, 2021 @ 12:57 am US Central): Fixed. Blasting out the XFCE settings stored in ~/.config/xfce/* was the answer. No idea what was corrupted in there. Any ideas?

EDIT 5 (Sunday, August 15, 2021 @ 1:36 am US Central): It happened again. Something is just very wrong with XFCE. No idea what. I suppose I finally have an excuse to force myself to use Qtile now.

Hello!

I’m having very strange behavior. It’s been a while since I tried to use a headless remote desktop setup with my Pi.

I set up nomachine again last night, and I’m finding some oddities:

The window decorations are missing from some applications (e.g., no window title bar buttons); 2) the whole UI, and the Pi, hard freezes after 5 minutes.
All connected SSH connections also die.
I’m seeing the same behavior in nomachine and VNC (using RealVNC server).
I’m overclocked, but that’s never been a problem running remote desktop servers in the past.

I’ve not tried to set up a remote desktop for at least 3 or 4 cycles of major system updates.

I know this isn’t much information to go on, but I’m a bit lost about where to start with this. What information would be helpful?

EDIT: Adding replies with inxi and Xorg log info.

in raspberry os you would normally set a screen size in config.txt.
maybe try that.

Interesting. Do you have an example of what that looks like?

I’ve run nomachine before with the posted config.txt, and never run into any problems.

Fixed. Blasting out the XFCE settings stored in ~/.config/xfce/* was the answer. No idea what was corrupted in there.

I take it back. That just solves the problem for anywhere from an hour to a day or so.

Unclear what’s happening, but it doesn’t effect the LightDM login screen, Qtile, or IceVM.
