[virt-tools-list] virt-manager can't open display



Hi there,

I suddenly found that virt-manager suddenly stopped working, throwing in a  "RuntimeError: could not open display"
root rakcal ~]# echo $DISPLAY
localhost:10.0

[root rakcal ~]# virt-manager 
Traceback (most recent call last):
  File "/usr/share/virt-manager/virt-manager.py", line 383, in <module>
    main()
  File "/usr/share/virt-manager/virt-manager.py", line 286, in main
    raise gtk_error
RuntimeError: could not open display


Has anyone seen this before? the same thing happen to "virt-viewer" as well:

[root rakcal ~]# virt-viewer winxp1
Cannot open display: 
Run 'virt-viewer --help' to see a full list of available command line options

Does anyone know what might be the problem? Reinstalling "virt-manager" didn't bring any good. Any help would be appreciated.

Cheers,
Santanu
