Graphical applications cannot be started after changing the hostname #773

AlexanderZhirov commented 6 months ago

After the hostname has been changed in the running icewm-session, the applications refuse to start. The following messages appear in the logs:

Authorization required, but no authorization protocol specified
xterm: Xt error: Can't open display: :0
Authorization required, but no authorization protocol specified
qt.qpa.xcb: could not connect to display :0

Works after the icewm session is restarted.

GUI windows do not open after calling hostnamectl set-hostname <name>.

Icewm doesn't concern itself with authorization. That is the responsibility of the X11 server, which we don't do. Icewm is an application itself.

Please don't submit the same issue twice!

@gijsbers If this is not an icewm problem, then what could it be related to? It is strange that changing the hostname affects the operation of the icewm session.
