can't boot to a graphical interface.

[Frank McCormick]

While compiling an application today my Debian bullseye system somehow 
got messed up. It will boot to a CLI but no X, apparently because for 
some reason the system is unable to access some files in 
/usr/share/dbus-1. It keeps saying access denied. The directories and 
files are owned by root, and if I noot to a CLI I have no trouble 
accessing them using sudo and midnight commander.

I tried reinstalling systemd but it ended with the same problem.
Can anyone help?

Thanks
