Hi,
.
I installed 13.1/Xfce in place of 11.2/Xfce. I kept my home as is (with all config files).
.
The keypad seems locked into the “mouse emulation” mode. I used to hit Control-Shift-Numlock to switch between mouse emulation and normal operation; now this is not working anymore.
.
Any hints?
Problem solved.
I desinstalled ibus, and I unchecked mouse emulation in Xfce settings manager.
I don’t know which step solved the problem, or if both were required.
(Looks like I cannot edit the thread title to mark it solved.)
