Take the 2-minute tour ×  I upgraded from 10.04 to 10.10 and
having been trying to fix this issue for a couple of weeks with
no luck.  Copy and pasting text is really wonky. Sometimes it
works sometimes no matter what I do and copy will paste instead.
I use different programs, thunderbird, firefox and gedit.
Sometimes it is fine others I can click all different ways with
no luck at all  Things I have tried:    • Installing various
clipboard programs. (Seems to be making the issue worse)    • I
tried using the esc key also  What does not work: Ctrl + C, Ctrl
+ V, mouse right click nor Edit > copy and paste.  I have a
Microsoft wireless 1000 keyboard/mouse and dual monitors. Just
as a test I put the live CD of 10.04 and could not get the
problem to duplicate. Nvidia graphics card...  Am I so messed up
may have to wipe and reinstall 10.04?  share|improve this
