Hey all, I'm new to Linux but openSUSE is the first distro I've really felt comfortable with and I'm really starting to transition away from Windows.

Sorry if this issue appears in another thread. I'm not sure how to describe it in a search query.

I used KDE to change a certain setting under "configure desktop" (I think) that had to do with desktop effects, or something like that, and after applying the setting, the screen went blank except the mouse cursor and after a reboot the same condition exists.

I think I might have changed a setting that is incompatible with my hardware or something.

Sorry I can't remember exactly what the setting was.

Does this ring a bell for anyone? Can I boot to a command prompt shell and edit a file to reverse this setting?

Thanks in advance!
