sway / wayland stability

I have been running sway / wayland for a few weeks and while I don't notice any visual difference compared to i3, I've experienced what appears to be hanging.

When I am closing my kitty terminal, it will hang for no apparent reason and will stay there until I properly kill it (kill -9 <PID>).

Additionally, I've experienced some odd behavior in micro when first opening files to edit. It is like the keyboard is stuck and so if I hit CTRL+K to cut a line, it will repeat that until I hit escape or quit.

I'm not sure if these are related or issues with sway or wayland, but originally, I was experiencing issues with notification-daemon segfaulting and so I uninstalled that altogether and instead use mako. I also saw a bunch of ACPI errors and upgraded my BIOS in the process.

Has anyone else experienced some odd behavior on wayland like this?

Is there a reason to use Kitty, I mean I don't know if that is the reason for your problem but AFAIK Kitty isn't Wayland supported.

I use Sway and Alacritty for a very long time and there are no issues, it has wayland USE flag.

Oh, good call, the issue is only when I'm in kitty, perhaps that is the problem.

I haven't gone through my other apps, but suspect that other apps may also be in a similar boat.

I use kitty instead of alacritty because it supports tabs, otherwise, I think for me, they're identical.

Also, I believe kitty does support wayland and automatically detects the underlying implementation.

I exit kitty by exiting each tab via CTRL+D. When it hung, I was unable to use that keybinding (CTRL+Q) to close the window. I had to kill it.

Hi o5gmmob8,

i think you should measure it. Wayland is the future cause of less lines of code and more up to date coding. And because you will report bugs and help to fix it.

Sure you can stay on X11 with a huge amount of known unfixed bucks and spaghetti code.

Just use and bugfix wayland.

This has been occurring more lately and I'm not sure how to best approach it because sometimes when it happens, my system restarts entirely on its own, other times, it seems kitty hangs.

I am on an old machine, Dell Precision M6800, and it is showing its age. I was on another machine (Precision 7540) and it would only hang, not hard reset.

Normally when something segfaults, I can see that in dmesg output, but as this is a hard reboot, I have nothing other than the correlation that anytime I close a tab in kitty, unexpected things may happen.

I think it is fine if I kill the wayland session altogether, but exiting a tab or session, not so much.

The only thing I can think of which I'm unsure on is, I still have X enabled because I think some other applications need them. I am still confused on that, I would think I would want it to be a pure wayland system (if at all possible).

Lastly, kitty supports wayland as it has a wayland use flag.

Any ideas other than don't close any kitty tabs and instead just exit wayland altogether with the hotkey?
