<div dir="auto">Most probable all those desktops require features that are not offered by NX. We have seen many cases where they do not correctly check what versions of x server extensions are available and assume higher versions. I am not sure but maybe EL9 apps are only tested against Wayland and not longer X11?<div dir="auto"><br></div><div dir="auto">Do you have more details when they crash?

<br>
I subsequently discovered that other desktops are similarly affected. All <br>
of them experienced segfaults or kernel traps in parts of their <br>
components, particularly in the Marco window manager that Mate uses.<br>
<br>
I have also tried Gnome, Kde, xfce, Cinnamon & Icewm desktops, again on a <br>
Centos Stream 9 system. Similar results were found on an Alma 9 system so <br>
I do not believe the problem is specific to the 'upstream' / lesser-tested <br>
nature of CS9.<br>
<br>
Apart from Icewm which remained usable even with the segfaults, the other <br>
desktops (particularly Mate which we use a lot for remote working) are <br>
rendered unusable by this problem. None of our Centos 7 systems have this <br>
problem.<br>
<br>
I am running out of ideas to diagnose/fix this problem.<br>
<br>
Any thoughts?<br>
<br>
Thanks<br>
