I needed to restart my gnome-shell. I did this on the tty1 via

export DISPLAY=:0.0 gnome-shell --replace

This helps to keep all the open programs, but all KDE program have a different (e.g. ugly) window decorations. Then I tried kwin --replace which looked pretty cool for 5 secs and then I found out, this won't work :)

Is there a way to get back the former looks?

(QT and XUL programs still look fine, firefox and others)

  • In Gnome shell you can use 'Alt'+'F2' then enter 'r' to restart the shell.

    Wilf: the gnome shell wasn't working that well, so I used the tty. But now I've tried your command, and all programs look fine...

Just restart the shell as you did in the TTY using

export DISPLAY=:0.0
gnome-shell --replace

(An alternative for the second line would be gnome-shell --replace & disown so then you can close the TTY)

Then you can restart it from the shell by pressing Alt+F2 and entering r - this should resolve problems with the theme.
