Remote X glx problems

[jesnow]

I log into my headless server using konsole with ssh -Y mostly, and work with the files on the shares using nfs on the clients. But every so often I need to use X applications directly on the server. This works fine for many applications (meaning that remote X is working just fine). Xosview (my favorite) and pcmanfm-qt both do their thing no problem.

BUT kde apps require glx and glx won't start. It used to work, usually I would start dolphin, to move files around directly on the server (for example) or access linked spreadsheet files from the time when that machine used to be my main desktop. That server is the only machine in my local network I can easily access from work, and sometimes I need to run things on it with the back end there and the display on my work or road machine. It all used to work. A little slow, but so what.

This question is not about RDP, VNC, NoMachine or any remote desktop solution, I know all about those. If I have a problem with them I will ask about that. It's only about getting something that requires glx running on a remote X window.

So when I go to start dolphin I get:

Geez, man, that chaos.....
Right now I have an impression that you can run KDE apps over SSH, but you can't run them locally on the server after you physically walk up to that machine, which makes it effectively your workstation and there is no point in even mentioning that SSH, because you're not using it when the problem occurs.

What are you trying to do on which machine and it doesn't work?
