Simon, I have had success in the past by using NICE DCV (now owned by AWS but you can get licenses for on prem) https://www.ni-sp.com/products/nice-dcv
An alternative would be VirtualGL
Altair Access (though more likely to work with PBS!) https://altair.com/access%5C

On our cluster we’ve noticed that if we use the native x11 slurm plugin (PrologFlags=x11) then X applications work, but are really slow and unresponsive. Even opening menus on graphical application is painfully slow.
On the same system if I do a direct ssh connection with ssh -YC from the head node the same applications are quick and responsive.
Any suggestions for what might be causing this, and how I can get the native x11 to have the same responsiveness as a direct ssh connection?
Many thanks
Simon.
