I tried this but it didn't help. Maybe because I am using VNC? I actually did find that VNC might be the problem.
RHEL5 uses vnc4. RHEL6.8 uses tigervnc1.1 I tried to install vnc4 in RHEL6.8 and it solved the problem. Though I'm sure there is a config somewhere that I can simply tweak. Anybody have any idea? I realize I'm pushing my luck here, since it looks like it's not related to SGE. Thank you anyway to all who replied. -----Original Message----- From: Dobbie, Brad [mailto:[email protected]] Sent: Tuesday, July 18, 2017 9:39 To: John_Tai; [email protected] Subject: RE: DISPLAY problem in RHEL6.8 We recently hit this issue in RHEL6.

I am using SGE6.2u6 I use VNC to connect to a linux server. By default the DISPLAY is set to :4.0 and I can start GUI jobs locally: # echo $DISPLAY :4.0 # xclock However if I submit a GUI job it gives me a display error: # qrsh -V -b y -cwd -now n -q mailto:test.q@ibm065 xclock Error: Can't open display: :4.0 At this point I set the display by adding the hostname and I can successfully submit the job: # setenv DISPLAY `hostname`:4.0 # echo $DISPLAY ibm041:4.0 # qrsh -V -b y -cwd -now n -q mailto:test.q@ibm065 xclock At least, it is successful in RHEL5. However in RHEL6.8 setting the display with hostname doesn't allow GUi jobs to start either locally or remotely: # setenv DISPLAY ibm046:4.0 # xclock Error: Can't open display: ibm046:4.0 # setenv DISPLAY ibm046:4.0 # qrsh -V -b y -cwd -now n -j y -q mailto:test.q@ibm065 xclock Error: Can't open display: ibm046:4.0 Hopefully somebody has experienced it before.
