Try to select another openSUSE kernel in Advanced Options as I suggested already. Does that work maybe?
At the moment, I entered root as the user name after choosing the Rescue option of the Net Install disk on the computer in question (a relatively new installation). I am then given a command line that says: Rescue (in red).
What should I type to continue? My purpose is to make openSUSE useful again. Can using the Rescue option of the Net install disk accomplish that?
I guess so. But as you can boot your openSUSE 13.1 installation to text mode at least, you could do it easier there.
You said the problem is cause by X not loading. So how can I get it to load? Furthermore, I need it load in relation to the installation on the hard drive, rather than with the Net Install disk.
No idea yet.
You would have to find out why it doesn’t start, the Xorg log as mentioned earlier should provide a clue.
Try to login as “root” (you may have to press Ctrl+Alt+F1 to get to a text mode login prompt) and try to run “init 5”.
Does X start?
What does “systemctl status xdm.service” say?
Also, I have been using Openbox as my window manager with the XFCE4-panel on another OS and am impressed with it’s speed and stability. If I have to reinstall open SUSE, perhaps I should use that option instead of Gnome (if Gnome and it’s X Window Manager - Metacity) are responsible for this problem.
GNOME doesn’t use metacity anymore, it uses mutter now.
But yes, this could help, depending on where the problem lies.
I wouldn’t re-install just yet though.
Try to set “xdm” as display manager in YaST->System->/etc/sysconfig Editor. (Desktop->Display manager)
You can run YaST in text mode by just typing “yast”.
You can also reinstall openSUSE’s boot loader with YaST. Just enter System->Boot Loader and just select OK immediately. The boot loader should then be reinstalled.
