SarPi on rpi4 libX11 error - no usable X

Hi all

i recently installed sarpi-current on a raspberry pi 4.
This is a headless setup but I did once -after the setup which was done over ssh as explained in https://sarpi.fatdog.eu/index.php?p=setupnic - connect a kb/mouse/tv to test the hdmi output. It worked fine and I started up XFCE.

Now I try to "ssh -Y" and I get the following error

~$ xlogo xlogo: symbol lookup error: /usr/lib/libX11.so.6: undefined symbol: xcb_get_file_descriptor

Googling does not bring this error up so I figure I must have messed the configuration somewhere:

sshd - I have enabled X11 forwarding.
ldd - seems OK

after the base installation (which was done on 3rd of August), I incrementally installed and configured some stuff on this RPi (dhcpd, bind, vpn, firewall stuff like that). The package installation goes like this :

As you see the is a few things that were installed after 3rd of August, of which the ones most related are the vnc* packages. Yes I did try to reinstall libX11 just to make sure a little while ago.

I am not sure what else maybe wrong here. Do you have any ideas?

Thank you in advance!
