Fixing epoll-shim on FreeBSD causes strange bugs on NVIDIA. (was: Strange behavior of XFCE after update to xlibre-server-25.0.0.7)

[elgithubo]

After the update to xlibre-server-25.0.0.7, XFCE refused to start.
Workaround: Each time before starting XFCE delete the file ~/.config/xfce4/xfconf/xfce-perchannel-xml/xfwm4.xml.
FreeBSD 14.3-p1, NVIDIA-FreeBSD-x86_64-575.64.05

Could you provide logs what happened: at least xorg log and and if it is written .xsession-errors at you home dir.

[elgithubo]

.xsession-errors does not exist.
I have attached xorg log and startx output (stdout & stderr).

Xorg.0.log

startx.console.log

Thanks.
Can you please also post the output of glxinfo -B ?

[elgithubo]

While the session hung, I switched to a tty and issued glxinfo -B -display :0.
The output is attached.

glxinfo.log

Sorry for the delays, I have read all the logs and can't really find the cause from them, and I don't have NVIDIA hardware to test, I think it would be best to send these PRs to the XLibre Xserver repo.

From 25.0.0.5-25.0.0.7 the only thing changed in the ports themselves was that I fixed the epoll-shim dependency, And I'm running it fine on my non NVIDIA hardware so it is unlikely to be that.

This bug has already been fixed upstream.

[elgithubo]

@callmetango now I am a bit confused.
I found the cause of this issue to be the newly introduced epoll-shim patch which can be seen here:
patch-include_meson.build
By removing that patch from the build the issue is fixed (and also the one I have closed as duplicate: #11).
Are you sure that this has been fixed upstream?

P.S.: Details:

Isn't X11Libre/xserver#554 the same as this issue?

Yeah it is the same issue but I closed it cause the problem is in the FreeBSD port (here) with the epoll shim.

I think this issue needs a rename, something like: Fixing epoll-shim on FreeBSD causes strange bugs on NVIDIA.

Thank you! I understand.
