I've re-installed twice with the same result. The applets in the notification tray are in visible (such as nm-applet, battery etc), but if I hover over them they work fine.
If I run nm-applet from the command line it will launch another instance (still invisible) but it does give a GTK-WARNING about icon size allocation and I notice the width of the icon is being set to -24.
Any ideas?
Thanks much!
I'm using an old gateway laptop and Gnome Classic sessions.
ps Don't have access to the logs here, so I can post if needed later today. Thanks!
