OS: Linux

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.

AhsayOBM for Linux v8.5.2.x and above, now force 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 DISPLAY variable was set” error.

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 & 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.
