I wonder whether anyone can help me please?
I am a private individual and have been using Ubuntu for many, many years and am now 76 years old. I have no programming experience at all but I can following instructions if they are clear enough for an amateur to understand and apply.
During the years using Ubuntu I have not experienced any problems until now. I am using Ubuntu 16.04 64 bit. I was using the computer a couple of weeks ago and a Security Update flagged up and as usual I installed it.
When restarting the computer later that day it loaded showing only my desktop but without ‘sidebars’ and the cursor was a black ‘X’. I was unable to move or exit from the desktop without switching off the computer. Right clicking the mouse showed a number of options but nothing to enable me to exit. I restarted and an error message popped up;- Executable Path /usr/lib/x86_64 linux-gnu/unity/compiz-config-profile-setter. Package Unity 7.4.5 +16.04.2017..
I was able to re-start in ‘Recovery Mode’ and the desktop appears I believe with all the relevant items that were there before, but the screen is elongated from left to right.
I shall be grateful for any assistance you can give to enable me to correct this situation and would like to express my thanks in advance for your help.
Best wishes,
Godfrey Dingley-Jones
