Two days ago I have updated my system from openSuse 11 to 11.1. Everything during installation was OK. After installation I have noticed that after loading my system is freezing and I can not do anything. Even mouse is not mooving. I have installed it on my laptop HP Compaq (HP Compaq nc6120 / Intel Celeron M 1.5GHz/1GB RAM/HDD 40GB/Grafika Intel 915GM System-OpenSUSE11.1/KDE4.1).
So, when plug is connected laptop immediately freezing, at this moment I can work only when I use battery, without charger.
You said you did a upgrade. Is that what you mean - or did you do a full new install.
Might be worth clearing all boot arguments and just type in the number:
edit to the above for clarity:
Pause the boot by moving the down arrow, then back up to the default boot. But now press backspace, it should delete any text where you can see VGA=.
Remove all text and now type just the number:
and hit enter
at the login type your user name and then password
then the root password
login as user and then go su and do
It has to be said I would favor a fresh new install always. You can keep /home as it is of course.
