Latest update has huge errors

[Adam-Cosner]

Currently running the latest git commits, and ever since I updated I have to restart multiple times for it to load the compositor, as there are panics and errors blinking on the screen from XWayland and Smithay faster than I can read them

Can you log into another desktop and post the logs of journalctl --user _COMM=cosmic-comp?

[gabriele2000]

Can you log into another desktop and post the logs of journalctl --user _COMM=cosmic-comp?

Ok I'll do that too, my issue is the same (#1114)

[Adam-Cosner]

The issue says "thread main panicked at 'No seat?': src/shell/seats.rs:69

Can you log into another desktop and post the logs of journalctl --user _COMM=cosmic-comp?

I have a similar issue but now it crashes before the login greeter. I edited my comment to include my other test machine with dual monitors. This one allows me to get into the DE but only one monitor works. Just in case it helps they run on different GPUs.

********This error line continues to go on forever^

[Adam-Cosner]

Tracked the general cause down to the switch to the new DrmOutput API

[nishithshowri006]

Having the same issue..

[marchaesen]

I have the same problem.
The only way I can login is by removing the ~/.config/cosmic folder. But then after logging out, the login fails again.

[nishithshowri006]

@marchaesen as a work around I had installed gnome-session, gdm3 for now 😅

[Drakulix]

42af2af should fix this.

[marchaesen]

Unfortunately not. I just tried 7f69244, and still cosmic-comp failing to start:

Latest cosmic-comp still crashes, after rm -rf ~/.local/state/cosmic-comp/outputs.ron, I can login, but cannot to change display settings (layout and refresh rate changed after deleting that file).

EDIT:
Also after reboot, it crashes again, and to login I need to delete that file again.

I replicated the crash and immediately after: journalctl --user _COMM=cosmic-comp --since="1 minute ago"

Jan 07 14:37:20 pop-os cosmic-comp[18982]: thread 'main' panicked at 'No seat?': src/shell/seats.rs:69

That is the crash that got fixed on master, are you certain you are running the latest commit?

[Drakulix]

Latest cosmic-comp still crashes, after rm -rf ~/.local/state/cosmic-comp/outputs.ron, I can login, but cannot to change display settings (layout and refresh rate changed after deleting that file).

saus. 07 15:12:30 vilius-pc cosmic-comp[2517]: Failed to set new config.

So this line indicates that some output-settings fail to apply, which would explain the behaviour you are seeing. Can you run cosmic-comp with RUST_BACKTRACE=1 (e.g. on a different tty or by editing /usr/bin/start-cosmic) and post logs again so I can figure out, what exactly fails to apply here?
