In the old Version 4.x.x under SuSE_13.2, the System Settings granted
the possibility to
setenv DISPLAY <host>:0.0
which was useful for opening remote programs.
As a preparation, there where sufficient some slight modifications to
/etc/X11/xinit/xserverrc
/etc/X11/xdm/Xservers
/etc/X11/fs/config
which consisted in removing the "-nolisten" or "no-listen" parameters.
Now, in the new Version 5.x.x under Leap 15.1, the environment variable
DISPLAY can still be set. But the above modifications are no more
sufficient because the system continues to complain
<program>: can't open display <host>:0.0, aborting
not only at the trial of opening a remote program, but even with a local
program.
How can the useful functionality of "setenv DISPLAY <host>:0.0" be restored?
Best regards,
Wolfgang
