It was a fresh install - over the top of an existing KDE4. As always, I install and wipe my /boot and / partitions, everyhting else being untouched. I used the DVD which I'd downloaded. It most definitely was perfect yesterday after I installed Mageia 5; looked like a totally normal log in. So, that's how I can be 100% sure that it was there after install yesterday and not this morning. Bear in mind that after I did the install yesterday, I worked the rest of the day on it (Mageia 5). It was the standard reboot after install to take me into KDE that showed the standard login screen and bog standard KDE4 desktop.
Something got corrupted/uninstalled somehow, there's no absolutely doubt.
On install I do as I've done for years and years through Mandrake and Mandriva. I selected a custom install, selected KDE and on top of the standard ticked boxes, also chose development and a few other installs like database, server etc. Exactly the same as I always do.
I can't stress enough that yesterday it was perfect. I did quite a lot of post install tinkering such as installing Qt Creator, Cutecom and all the other packages that I use on a day-to-day basis and it worked the whole of yesterday perfectly.
The login manager that is currently selected is KDM. the only other option I have is XDM. At login, the screen looks blue on my main screen, one screen is about half blue and the rest white, with the other two screens white. The login is achieved by typing my user name into the first box, hitting enter, then entering my password. At this point, now, after reinstalling KDE from MCC, all four screens are normal and their orientation just fine.
It says KDE 4.14 on the start menu.
What's really weird is that the login screen looks corrupted, whichever one it might be. I could take a photo and upload it if it would help.
