LINUX AS 4.0 x display

[Cliff Lim Kok Hwee]

Hi Forumer,

I login as user appuser locally and perform export DISPLAY=:0.0

But when running xclock it is prompting display not set.

But when i run remotely from my laptop and having software X CLIENT REFLECTION started and i perform the same export DISPLAY it is OK.

Query: Why it is happening locally on my monitor connected direct to my server? for root user it is OK.

Need forumers advise.

Thanks/cliff

This is extrange. What is the status of SELinux. When I have weird problems, my first action is to disable SELinux.

Also, ensure that when logging directly from the console, no other user has logged into the console before, this is because the console device permissions are set for the first user that logons to the console.

Check if the /usr/bin is in path of the user.

Hi Forumers,

I found out the REASON. Because I login as root on my monitor console which lauch the GNOME desktop and then launched open terminal which open a root session then I su - appuser. Follow by export DISPLAY=

SOLUTION: I login as appuser on my monitor console instead and then launched open terminal which automatically open as appuser session. Dun need export DISPLAY I can launch xclock without issue.
