I don’t know (yet) how stupid I can get. I had kind of thought that I wouldn’t touch Gnome 3 with a ten-foot pole (nor, for that matter, not again mess around with a new release of openSUSE) because I don’t know how to fix anything.
Since I enjoyed Gnome shell with Ubuntu 9.10 (but Ubuntu runs too slow on this computer for my druthers), I thought it would be fun to check out gnome shell on 11.3. I thought that since my 11.3 has gnome 2.30, that the gnome shell in the software manager would be a concomitant version, so I installed it. I then followed the directions given in the second posting of Enabling Gnome Shell in 11.3?
When I logged back in, I selected Gnome 3 Preview [even though I hadn’t thought that that was what I’d installed – (has openSUSE retired all older versions of Gnome shell?)]. The desktop won’t boot (I don’t know what the correct way of saying it is). The splash shows, but the icons just intermittently flash off and on at random intervals, never quite making it all the way “on.” When I right click the bottom of the screen, I can select “terminal” (when I can accurately coordinate my double-click with the random, intermittent flashing), but then the terminal also does the random, intermittent flashing as well. So I can never get anything typed in. When I reboot, there’s no login box.
How do I undo this mess? Any help would be much appreciated.
