I have 12.1 installed on my box and today I did the over the air upgrade using Konsole. I followed the commands but skipped some errors that were blocking me.
12.2 loaded successfully and I can see all the 12.2 graphical changes, except for when you choose which os version you want to use, I choose 12.2 and it goes from there to a black screen with a command line, and when I log in and give pwd; all I have is the konsole.
It's just the command line...that's it.
I did some research and used some commands given and nothing has worked.
I know that's not really a good explanation but if anyone has suggestions or further questions, just ask.
Thank you in advance.

what errors ?
one of them might have been installing NEEDED things


You DO have a full back up of YOUR data , music,photos, documents , web bookmarks,encryption hashes ,...
do a clean new install and move over your data from your backup

I have never had a "upgrade" ( except for CentOS5 5.1to 5.2 to 5.3 ... and Scientific Linux6.1 to 6.2 to 6.3 ) work ,never.

and suse has a LOT of incompatible third party repos ( THAT DO change system files !!!)
Packman for starters then OBS
