After apparently completing successfully today's updates (i486 pae Mate) using synaptic, I now have a shed load of problems:
1. No task bar (therefore no menu system or tool tray).
2. Cannot move or reposition windows.
3. Desktop wallpaper has changed and the original SparkyLinux wallpaper is not available to select, just a lot of green shading to blue desktop wallpapers.
There are probably many more, but not being able to navigate the system well, or able to run many programs (due to no menu), it is difficult to say.
Changing to an older kernel (upgraded 30 Sep from 3.14.2 to 3.16.1) makes no difference.
Any suggestions will be gratefully received.
