I have ubuntu 10.10 with the 64-bit desktop version. When I copy-and-paste into any window, including firefox, terminal, java swing app, remote desktop, often I get 4 random letters (a 32-bit value?) if I try to copy again it may work this time or I might get another corrupt sequence.

This happen more often than not. I have tried to search for a solution but it doesn't appear to be a common problem. Any suggestions on what I should try next to fix this?

It appears that copying twice helps ^C^C often works.

EDIT: I have traced the problem to using remote desktop to a tightVNC server. When this is running the copy/paste doesn't work well. When I don't that this running there is no problem.

That's very strange! Try using a clipboard manager to see what is happening a little better. Parcellite is in Software Manager, and the far more comprehensive Glippy can be found on Launchpad. I don't have an answer because I've never come across this bug, but these programs might help you diagnose the problem better. –  Deadite81 Dec 16 '10 at 16:18
    
@Deadite81, I don't have a clipboard-manager installed AFAIK, as I have only found them to cause problems in the past. I will try Parcellite to see if it makes a difference. –  Peter Lawrey Dec 16 '10 at 16:36
    
parcellite -c prints ²½ (plus 3 special chars not show here) –  Peter Lawrey Dec 16 '10 at 16:40
    
Really? I can't live without a clipboard manager! I can live without Ubuntu 64bit though. I had so many problems with it I went back to 32. Maybe it's a bug only affecting 64bit systems. –  Deadite81 Dec 16 '10 at 16:42
    
Hm. That's beyond my expertise! –  Deadite81 Dec 16 '10 at 16:44

You should report the issue to the TightVNC developers so that they can fix the issue:
