I wonder if anybody has any suggestions for me to try with this problem. After I upgraded to 13.2, my external monitor no longer works if I am logged in as a user. If I log in as root, all is fine. As a user, nothing I can do with the external monitor connected lets me see anything but garbage. If I remove the external monitor, <ctrl><alt>F12 and then <alt>F7 I get back to my original screen with nothing lost. I have tried both unified outputs and non-unified outputs in configure desktop/display with the same results.
I suspect that there is a config file screwed up in my user directory, but have no experience with video so don’t know which. (40 years experience with command line 
)If I knew how to do something from a command prompt I am sure I could fix it, but cannot get into any KDE graphics tools with the external monitor connected.
Here is my config:
Tosh Satellite L300D
LG Flatron L1511S monitor
cat /etc/os-release

Any help would be appreciated!
