CentOS

I installed KDE from terminal and it's successful.
[b][color=#0000BF]yum groupinstall "KDE Plasma Workspaces"[/color][/b]

now i'm unable to find login button for kde when i log out of gnone session.
can i reinstall KDE from terminal?

There should be a little circle thing that looks a bit like a cog wheel next to the Sign In button, press that and it should let you select which desktop to use.

yea, trevor, i got it. it's working.
