xlib extension error after 11.2 upgrade

After upgrading to 11.2, I get the following error when starting any xclient. Worse, its usually repeated a few times for each client.

Xlib: extension “Generic Event Extension” missing on display <my_ip>

I get this both when using Xming and nomachine.

Any ideas or workarounds?

thanks,
adam

I only get this inside an nx client (which uses a different value for DISPLAY i.e. NOT :0.0) I’m on 64 bit suse. This is hugely annoying!

Same problem, only thru NX after using YaST… but this is a fresh 11.2 install (not upgrade). Any ideas?
