Non-functional system after disconnecting USB-C monitor

gnojus · 03-01-2024, 02:12 PM

Hi,

I'm having trouble with my system after unplugging my USB-C monitor. I think it started after upgrading to Fedora 39 from 38. The graphical session is KDE wayland.

I'm not really sure how to describe, what's going on. Basically, many things are going wrong, for example:
- most of KDE taskbar features doesn't work, firefox does not start
- tty logins are slow: it takes ~10 seconds for shell prompt to show up after correct credentials
- sudo does not work at all: it hangs, and you can't ctrl-C or ctrl-Z it
- `systemctl reboot` fails with "call to reboot failed: ... restart/sleep already in progress"
- you can click shutdown in KDE, but it does not succeed. After some stop jobs it fails to unmount /home, and finally waits on "Powering off"
- after force shutdown via holding the power button, the system seems to work ok

Does it makes sense? Any idea what could be going on?
I can obviously provide logs, but just wasn't sure where to look, etc.

Thanks

Sounds like the kinds of problems that could occur if it were interrupted while doing updates.
Open "Updates" and check if you are up to date.

In some cases a monitor is needed to continue programs.

Upgrades have always been a sore spot.

If you are talking about Fedora package updates, I don't think those are related.
I have uninstalled/disabled Fedora auto-updater (don't even seem to have a GUI software app),
I refresh dnf cache and install upgrades manually via dnf cli.

As a side note, this is not a once-time thing -- it happened a few times already.

Ok, after a bit more of messing around:

Looks like it's consistent, that is it happens every time I disconnect said USB-C monitor.
After checking journalctl, looks like there is a panic in some kernel module?

Does the same thing happen in an X11 session instead of Wayland? Does the same thing happen in an IceWM session instead of Plasma?

SDDM could be playing a part too. I've stopped using it in Fedora. I use either XDM, LightDM, KDM or TDM in Fedora 39 & prior for running Plasma.

Does your normal connectivity require wireless? If not, switch to another method, such as static IP, and/or use something other than NetworkMangler. My Fedoras all use systemd-network, same as all my other installed systemd distros.

It appears that problems with r8152 being non-functional after reconnection are known. Success after using ethtool to disable scatter-gather is reported toward the end of that.
