There are other similar questions related to mine (e.g. VNC viewer issue - showing black screen ) - my case seems a little bit different: I start vncserver on my CentOS 5.8 host, which acts as a VMware Workstation 8.0 host, and use TigerVNC to open a desktop window from my Fedora box.
I get the twm desktop as expected (have several similar setups), and start vmware (relevant here, I think).
All seems to work like a charm, i.e. I operate on the VMware WS GUI, able to start/stop, or enter/exit each VM console etc.
But if I leave it inactive for a while, the VNC window goes suddenly black... and the whole VMware environment that was running is killed... all the VM instances are gone ! (vmrun list count is 0 !). A most undesirable situation - as I must then hurry to restart them via ssh.
Closing the TigerVNC client doesn't help - when opening it again, the black screen continues showing. Only killing vncserver (vncserver -kill :1) fixes this... until the next occurrence...
The vncserver configs are the default ones.. and as said other machines that I have are stable (can leave the VNC client desktop open for days at once).
Any hint ?
Thanks in advance!
