There are many clipboard managers available.
The first one I used, I found out if messes clipboard history if clipboard contents was multiline - which I found to be very lame and naive
Second one which I use now is also faulty - I wanted recent clipboard content and I found it's not present in history. I deliberately copied piece of text and text is not copied in history so I can't reuse it, although if I select edit clipboard I find the contents that I just copied
Can someone with more experience suggest reliable clipboard manager, with panel icon or indicator icon feature?
I tried Glipper and Parcellite, because they were on the repos. I ended using Diodon because neither of them worked well for me. One of them (I don't remember know which) had a bug that made it copy every single letter from a selection to the clipboard:
If I selected "foo bar" from left to right, I would get "f" "fo" "foo" "foo " "foo b" etc
in the clipboard.
I was using Diodon in 11.04 and I got back to it, even via a third PPA, in 11.10. It works great.
I first installed two managers: Anamnesis and Glippy
Anamnesis had some interesting features, but I dislike it UI window implementation
Then I used Glippy, for a week now, without any issue, and I now recommend it to others who didn't have a chance to try various clipboard managers
To provide promised information:
first one (which makes mess from multiline clipboard) is Glipper
second one (which stalls occasionally, and needs clipboard reset to continue working) is Pastie
This is one of the best indicator-style applications named CopyQ. It is not in Software center, hence a download link. Runs great in Ubuntu 14.10 so I am surprised nobody have mentioned it.
You can check Keepboard. It's been around for a few years and people were not complaining about its stability...
