I installed the KDE desktop environment with the software center but can't seem to remove it

Asked by Steven D. Shown

I am running Ubuntu 11.04 and decided to try installing the KDE desktop, so I did so from the software center. But I am not satisfied with it as it drastically slows down my computer when the desktop effects are enabled. This doesn't happen in GNOME, and I realize that all I have to do is boot into Ubuntu or Ubuntu Classic at log in, but the KDE packages are just sitting there eating space on my hard drive and I wish to remove it. All attempts at uninstalling from the software center have failed, and sudo apt-get remove isn't doing the trick either. Is there any way I can remove this package and reclaim my disk space?

If you run:

sudo apt-get --purge remove `dpkg -l | awk {'print $2'} | grep kde `

It will remove all packages with kde in the name, you can then run:

sudo apt-get --purge autoremove

to remove the rest. HTH

Thank you very much actionparsnip, that corrected the problem. But I can't help but wonder why the kde desktop brought my system to a dead crawl when the desktop effects were activated, but when running the gnome desktop I can switch on the effects, have full aero-glass to the menus and window borders, etc and the system is still lightning fast. If you or anyone knows the answer to this problem I would sure like to know! Again, many thanks.

KDE uses kwin as its WM, you can make KDE super fast by disabling some of the effects.
