Could you please advise if you built from source? I am assuming you did if you are running bulseye.
I suspect this is due to Gmocappy expecting to find a X windows environment when the default Debian desktop environment uses Wayland so the expected files do not exist on your system.
You may get more cluses if you open a terminal windo and run linuxcnc from there as more error mesages will be displayed. Please share the output.
Could you try this to get rid of Wayland.
at a terminal type:
Code:
sudo apt-get install
tasksel sudo tasksel
Select XFCE and install it
Logout back to the logon screen. Place your cursor in the password field and a cog will appear bottom right and select XFCE and login normally.
If the problem goes away well and good.
If it doesn't, then its missing some other dependency. I suspect this would be because the Gmocappy maintainers have not included all dependencies in the Linuxcnc .deb build system.
In either case, please report your issue here so th edevelopers can investigate.

It would be helpful
