Thanks for coming back so quickly
(1) Come to think of it, it might be better if I didn't use the GNOME desktop with VNC, especially if it's going to screw up my desktop settings every time...
This is my /$HOME/.vnc/xstartup script:
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
According to the VNC tutorial at fedoranews.org, the two lines "unset..." and "exec..." should be uncommented, presumably so that I'd get the GNOME desktop. If I comment them out, would I just see the "grey weave" twm display (i.e. what I want)?
(2) I'd better clarify this question
On Windows (esp. ME and older), VNC just works for every user who wants to connect. If I understand correctly, on VNC/Linux as I've set it up right now, only user "tim" (i.e. me) will be able to make use of VNC, as that is the only user in /etc/sysconfig/vncservers.
If I want my brother to be able to SSH into my Linux box from outside and tunnel a VNC display through the connection, would I need to add him to /etc/sysconfig/vncservers?
(3) This question (how would I disable wallpaper display through VNC, to save bandwidth) is probably redundant now, if I switch from GNOME to twm as above.
