unless proven otherwise this is an xorg/xwayland issue

The xwayland service did crash twice and I suspect this commit 6967a31450441fc5605c05db6f65505dace4b263 . I will run Hyprland with this 6967a31450441fc5605c05db6f65505dace4b263 and the previous commit to test rootless xwayland.

I am running xwayland with no issues

It was running for a while and suddenly crashed. I was using intellij-idea and intellij-idea was suddenly shut down, launching intellij-idea from kitty revealed that it was xwayland services that had stopped. Something like the following error.

Just the same problem after today's upgrading...

hdm9527 commented 5 months ago

That's all the info I have so far, no way to reproduce it yet, XWaylan crashes randomly. From coredumpctl it looks like it's an internal XWayland call error.

displayfd write failure causes Xwayland to abort server.

vaxerski commented 5 months ago

wayland display or X display?

if wayland, maybe it's simply overflowing the buffer? Though idk why that'd happen.

X display? Only the xwayland app is affected. This commit 6967a31450441fc5605c05db6f65505dace4b263 has this problem after merge.

MCSeekeri commented 5 months ago

Same problem, hard to reproduce, some days it can work for hours without errors steadily, other days it may crash multiple times in half an hour. My computer is Intel+NVIDIA, and the logs don't give any further information at the moment.

Thanks. The reason is that fs.file-max is not limited by default. https://github.com/systemd/systemd/commit/a8b627aaed409a15260c25988970c795bf963812

❯ sysctl fs.file-max
fs.file-max = 9223372036854775807

I don't think modification fs.file-max can help to solve this problem. I still got this problem! This time, even the chrome browser can not started again.

It is really not solved, more like a file descriptor leakage. My problem is all xwayland apps are simultaneously closed. Refer https://github.com/swaywm/sway/issues/5946

And is any way to solve it? I had to siwtch to other DE to work...

Downgrade to Hyprland v0.40.0 or use other WM/DE.

Well, seems nothing else to do...

vaxerski commented 5 months ago

if you still have crashes, report them to xorg developers. It's xwayland crashing after all, not hyprland.
