XFCE black screen and cursor loop

LaeMat · 2024-11-12 04:20:46

Hello. Recently I updated my laptop (sudo pacman -Syu) and I came back to it looping between the terminal and a cursor. I rebooted and it persists, rendering it unusable. I can access TTY through the usual shortcuts. I do have network access, so I can install and uninstall packages if needed. I'm not sure what to start with, as many of the results on the forums and wiki are unrelated (I'm using a Celeron N3060 with an iGPU, nothing Nvidia. I also can't access the greeter or see the login screen.) I have provided the systemctl and startx logs. For extra clarification, I installed this last year through archinstall with the XFCE profile. Thanks.

Just my two cents, disable lightdm and start from xinitrc...(if you didn´t try that already).

https://wiki.archlinux.org/title/Xfce -> pretty much high up on the page..

That's not something I had tried yet. Not sure how I didn't realize I could do that.
XFCE boots, but stuff such as xfce4-panels does not load. Not sure what to do next.

Is not from a ligtdm start, you'll find that in /var/log (as well as the lightdm logs)

pacman -Qikk lightdm-gtk-greeter lightdm gtk3

Possibly your gtk theme?

In doubt see https://wiki.archlinux.org/title/Core_d … _core_dump and https://wiki.archlinux.org/title/Debuginfod for a full backtrace.

Regardless of that, if this is a de-facto single-user system I tend to agree w/ jocheem67 and skip any DM and boot straight into a (in doubt locked) GUI session.

LaeMat · 2024-11-12 15:52:41

I was able to get it working again. In lightdm.conf, the greeter-session was commented out. I set it to this, and it now works as intended.

greeter-session=lightdm-gtk-greeter

I was able to run xfce4-panels with dbus-launch (After a MIME update and session cache clear), and that seems to have brought back panels, but I don't know if every app works.

That looks ok and there's a xfce4-panel that doesn't look dbus-launched at all?
What happens if you don't dbus-launch and just run xfce4-panel ?
If it's just about the panel not starting w/ the xfce4 session, that's probably rather the session config.

If I quit xfce4-panel and relaunch it, it now works fine. It opens on startup anyway. I'm not sure what changed, because before doing so, i'd get this:
