Hi,

I have some annoying problems. After downgrading from kubuntu 11.04 to 10.04, some programs (firefox, google desktop, deluge, avidemuxGTK...) have ugly, old-styled graphics. To show you what I mean, I include some screenshots:

I created a new user and in this, everything was the way it needs to be. So there must be some settings in my home folder from 11.04 in conflict with 10.04 (I used the same user throughout two installations). So, which folder do you think I have to delete? I don't want to delete every setting, cause don't want to lose all of my settings...

thanks for helping me out

If you don't want to lose all of your personalized settings, you pretty likely have to spend some time moving things around and doing logout-login cycle. I'd start with directories like .gnome(2) and .gconf under your home directory; create a temporary directory and move those dot-something directories there one by one, log out and in and see if something changes. After login those directories are probably re-created, so if you're not satisfied, simply move the original directory back from the temporary directory, overwriting if needed. I don't remember which ones held the relevant configuration files, but I've had similar problems in the past and this helped then (I'm not outruling other possibilities, though--I bet there is no "official" support for downgrading a distribution, and personally I'd expect problems in any case). Only I was lazy and simply removed a bunch of the directories, as I found it easier to re-do some settings (takes a moment or two) than spend a day moving files and directories around one by one, hunting for "the right one". Another possibility is to start going through the relevant documentation about where GTK-related settings are stored nowadays, but it'll surely take time.

Shortest route: just clear any directories under your home directory whose names begin with a dot, unless you know you don't want to remove them, e.g., have modified them yourself earlier. Clear means here "move to a temporary directory, restart desktop, and if nothing is broken, remove temporary directory".

I've found it quite fast actually. Just searched the net and found that GTK settings are stored in the file /home/.gtkrc-2.0-kde4 . Just delete this file and everything is fine as normal!

Thankx for help
