I don't even know where to begin to diagnose this one. Usually, when a command finishes, the prompt prints itself for the next command. However, that is not happening. Hard to explain with words, I'll just use an example:
User@Machine:~$ cp /mnt/mountname/directory/textfile.txt .
After waiting several seconds (far too long for this operation on a small file) I press Enter, and see:
User@Machine:~$ cp /mnt/mountname/directory/textfile.txt .
User@Machine:~$
User@Machine:~$
So clearly the operation had finished, but the prompt didn't display... until I pressed enter, and then BOTH prompts instantly displayed.
This basically just seems to be a lag issue overall. There is no real predictability on what causes it. I tried upgrading to 12.04.3 (3.8 kernel, lts-raring) and that did not help.
Update: Just now I did an fgrep on a large text file and it returned correctly. But then I typed ls immediately afterwards and THAT didn't print anything until I pressed enter again. This behavior seems inconsistent more than anything else.
Update2: At some point I think a number of packages got deleted. I compared dpkg --get-selected with the 12.04 manifest; here are the packages that are not installed. Could any of them being missing cause the problem?
