Mageia forum

Just a warning. I've filed https://bugs.mageia.org/show_bug.cgi?id=5098 for this, but if you are a GNOME user and want your system to remain usable, avoid updates for the moment!

EDIT: This bug has now been fixed.

I have added the following comment in bug 5098:

I can confirm this bug. My test system has both
KDE4 and Gnome installed and was defaulted to
boot up into KDE4. In KDE4 I logged in, updated,
then rebooted then logged into KDE4 again,
successfully. I then logged out of KDE4 and
attempted to log-in using Gnome and got the
same full screen error message reported here.

Subsequent testing tells me that so long as
Auto Log-in is disabled I can successfully
log in to KDE4. For now I am going to leave
Auto log-in turned off.
