AhsayOBM: 8.5.2.x and above, 9.1 and above
Operating System
Linux
Symptom

Using VNC and try to launch AhsayOBM, the user interface will not be displayed in the VNC session. Instead, it's opened in the display :0.

Cause

AhsayOBM for Linux v8.5.2.x and above now forces OBM to show in "display 0" (Host/Hypervisor Console) to resolve certain Linux GUI environment issue where not setting a DISPLAY target will encounter "No X11 DISPAY variable was set" error.

Resolution
  1. From your Linux client, locate the AhsayOBM directory and edit $OBM_HOME/bin/RunCB.sh, to find "DISPLAY=:0"
  2. Make the changes according to either of the following options:

    Option 1: If you only control OBM from a specific VNC display number, change 0 to the VNC display number you use.

    Option 2: If you control from the host & different VNC displays, comment out the line: #DISPLAY=:0
  3. Save the changes
  4. Try to launch OBM again and see if it loads up successfully.
If you commented out the line and got "No X11 DISPLAY variable was set" error when trying to launch OBM, revert the changes in 2 and use the other Option stated above.
