I'm currently running Redhat 7 and I was messing around with the KDE control panel when I saw a button labeled "window manager". I clicked on KDE, and it said to restart the X server, so I did. When I came back on I had no desktop. Only the menu bar at the bottom of the screen was there. The rest of the screen was just blue. It won't let me right-click on where my desktop used to be. Does anyone know what happened? Please help. Also, I heard from a friend that I can play windows games in linux using a program called whine. Where do I get this and how do I use it? Thanks.

actually it's called..........wine or for games using directX you can use winex/cedega

you can get wine at www.winehq.com. As for the KDE thing, log into just the cli and bring up your home directory. type ls -a. This will list all the files (even hidden ones). Still erasing the (rm) the file that would read something like .kde...blah. Then restart X. See what happens.

.kde is a directory so it would have to be rm -r .kde
When you login, check what session or wm type your selecting before you enter your password, are you sure KDE is still selected and not something like twm?

My friend told me to use "switchdesk kde" and when I did it said something like "now set for KDE" but when I restarted X nothing new happened. I still don't have a desktop. I typed switchdesk again and it said "for system defaults, remove /home/user/.xclient". What does this mean? Anyone have any ideas? Thanks.

wine is different from winex. Winex is now known as Cedega. Wine is free and open source but not for gaming. Cedega is a commercial project and I would say your damn lucky if a game runs fine in it. Some games do work well, only way to find out is to experiment. UT series, Quakes, and RTCW all have Linux ports which work great (and no cedgea is used).

Did you remove .kde from your home directory? When it said "remove .xclient", just remove it. Then it will use ".xclient-default" instead.

I tried to, but i don't know the console command to remove something. Anyone?

Just one to push this back up to the top.

rm -r ~/.kde

Should remove the directory.
