I'm really sorry that I can't put this issue in more precise words. I hope you can understand what I mean.
I now run Mageia 6 on all my machines, using the default Plasma desktop. One of the few modifications I have made is that I have chosen the Air desktop theme because I don't like Breeze.
After installing the latest updates a few hours ago, I noticed that the desktop no longer had translucency (which Air normally does), and that the rounded corners of the menus were not drawn properly. This is not a big issue, but seemed odd.
What is a big issue is that I can now no longer log into my user desktop at all after a system reboot. The computer starts up and so does the X server. The graphical login screen appears, and I can enter my login and password. But when I click on "Login" or press the Enter key, the Plasma desktop doesn't start. I'm stuck on the login screen. I have waited for a long time, and I have tried this several times after rebooting. I can't log into IceWM under my usual user name either, so the issue is probably in my user directory.
I am still able to log into another user profile (created just for testing purposes and essentially blank) using either Plasma or IceWM. So I can use the machine in graphical mode, and I have access to my documents if I become root. But I'd like to know what has gone wrong with my login, and how I can fix it.
Any ideas?
