I'm new to fvwm, although I used X11 a lot in the previous millenium.
I'm connecting from my Win7 laptop to an Ubuntu box with "tightvnc", running
tightvncserver on the ubuntu box and TightVNCViewer on the Win7 laptop. I get
to the ubuntu box through an intermediate jumpserver, and I have a local port
forward so the Win7 laptop can use the vnc port.
In my "~/.vnc/xstartup" file, the last line runs "exec /usr/bin/fvwm".
When I run the client and connect to the port, I can get to the fvwm context
menu and create an xterm, and from there create other windows.
The strange thing is that after I've been working with this for a few minutes,
and then perhaps switch the focus to other windows on my Win7 box and then
later return to the vnc client window, I find that all I see is a grey fvwm
background. I can create another xterm window, and if I do "ps -elf | grep
xterm", I see the original xterm window, not to mention other windows that I've
created. Also, if I select "Restart fvwm" from the context menu, I briefly see
all the other windows that I've created, and then they disappear.
I've gone through this sequence a few times now, and it's repeatable.
Why might those windows be disappearing? Is this a fvwm problem, or a
