FVWM key bindings not working on remote VNC connection on Ubuntu 14.04.5 LTS

Problems with decorations or key/mouse bindings? Or perhaps you have a cool mouse/key binding you want to share.

FVWM key bindings not working on remote VNC connection on Ubuntu 14.04.5 LTS

Postby trivedia » Wed Dec 14, 2016 7:26 pm

On Ubuntu 12.04.5 LTS I had been successfully running FVWM on a VNC server (I have tried vnc4server and tightvncserver) and then accessing it remotely using a VNC viewer (I have tried xvnc4viewer and ssvnc). However, when I recently upgraded to Ubuntu 14.04.5 LTS, everything still works, but the key bindings on this remote FVWM session do not work (On a local, non-VNC FVWM session there is no such problem).

At this stage I am not sure where the problem lies, whether in Ubuntu 14.04.5 LTS or VNC server/client software, or something to do with FVWM or its configuration while running on a VNC server (see below for the two versions of ~/.vnc/xstartup that I have tried). However, other desktop environments that I tested, for example gnome-session and openbox, do not show such key binding problems.

I would appreciate if someone could give me a solution or ideas for obtaining a solution.

~/.vnc/xstartup, version 1
--------------------------
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
fvwm2 &

~/.vnc/xstartup, version 2
--------------------------
export XKL_XMODMAP_DISABLE=1
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS

[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &

exec fvwm2

So far the solution for me has been to install the FVWM version that worked with Ubuntu 12.04.5 LTS (Precise Pangolin), which is version 1:2.5.30.ds-1. This version works continues to work with Ubuntu 14.04.5 LTS (Trusty Tahr) (The FVWM version that came with Trust Tahr is 1:2.6.5.ds-3).

To add more information for the original problem, I think it may already be encapsulated in the following bug report:

There was also a debian bug on this and it was due to a patch in the 2.6.5 debian source. In the newest 2.6.7 package in Debian this patch is no longer applied and this should work. I know the package has made it into ubuntu, unsure the best way to get it as I don't know how the universe works in ubuntu.
