I have upgraded Open Suse to 13.1 (kde 4.11.5) using the online upgrade on a headless workstation. It is configured as a firewall/router for two networks. I access it via VNC. Most things seem to work just fine with the exception of YaST2 which won’t launch from either the menu or from the “system settings”. From the former it opens up a tab on the bottom of the screen and shows a bouncing YaST icon for about 10 seconds which then vanishes as does the tab. On the latter it tells me that “yast is an external application that has been launched” (it hasn’t). In neither of these two cases is anything written in /var/log/YaST2/y2log
This is not super important, just irritating, since I can easily launch it from the command line using yast --qt when root. It behaves ok then although launching any of the sub-applications does result in "Unknown config. Invalid snapshot ''each launch. I have looked this up and it seems that they are harmless, having something to do with snapper which I have not configured. I did try using yast --gtk but it tells me that gtk is unavailable and defaults to qt. Launching it without options gives me the text version OK. If I launch it without being root it just tells me that I can only do non-root things.
When I launch it via the command line much gets written to the log.
This leads me to the slight suspicion that it might be something to do with the inability of the launcher to ask me to type in the root password, but I haven’t the faintest idea how to go about debugging that.
If someone has an idea where I should look, I would be obliged, bearing in mind I do have a command line workaround.
Thanks in advance.
