of no help whatsoever, but I have a theory! Do you use xfce? And try a few things for me..> can you flip over, or mouse over, or otherwise task switch and type elsewhere, then return to where you wanted to and still not type?>Load the clipboards with something and try cut-n-paste a few letters into where text should go, try douibleclick paste from a terminal and from a text file ctrl-v and right-click menu it it's an option, THEN return to where the copy came from and test the paste...?with the answers I may only say "huh, interesting.."But this seems similar to an issue I get every so often, the mouse, or pointer, gets divorced from the keyboard. Mouse focus doesn't move the keyboard focus. That's why I'm asking for you to go back and forth and see if this is happening.
