on starting a number of apps I am seeing multiple lines of
Xlib: extension "Generic Event Extension" missing on display ":0.0".
I've read several postings saying ignore not a problem, unfortunately it is a problem for a number of bash scripts we use with Xdialog as it gets those messages instead of the users input !
I unfortunately read it is related to xcb and saw in synaptic there was a newer version available, to install that it removed vlc. the update did not resolve my issue and now of course I would like vlc back, but synaptic tells me it cannot install due to dependency issue(s)
