Multiple problems using vnc4server under Meerkat beta livecd

[Kalman Reti]

In the beta livecd, I did "apt-get install vnc4server".

This worked in previous releases.

Although the install worked and the vncserver started, the first problem was that attempting to
type in the terminal window made it disappear!

I started an emacs on that screen, and the same thing happened.

Looking at the processes, I noticed x-window-manager was running, so I kill it, installed
open-motif-clients and started mwm instead.

All the windows came back (now decorated Motif-style), so they were still there.

I remember using that emacs for a little while without any problems.

Later I started up another emacs, and it dumped core, saying

Gdk-ERROR **: Failed to get keymap

When I tried to report that as a bug using the bug-reporter, the firefox that came up
on that screen had strange colors which made the page unreadable, i.e. the background
was a deep bloodred.

None of these problems existed in older livecds.

The typing a key causing the application to disappear seems to be related to bug 638686.

The strange colors happen only if I make a depth 32 vncserver, the colors are OK if the depth is 24.

With the default window manager (x-window-manager) and vnc4server, typing a "d" to a terminal window makes the window disappear. However, if you kill the window manager, it comes back undecorated.

I loaded the lesstif-bin package to get its mwm, started it on the x-server screen, and can type commands that
window normally, i.e. 'd' doesn't do anything special.

What I did to reproduce the problem:

boot meerkat beta livecd
apt-get install vnc4server
vncserver -depth 24 -geometry 1920x1200

look at the vnc screen with a vnc viewer (on Windows, in case it matters)

typed uptime at the terminal window, got its output

Tried to type "date", but the d made the window disappear.

sudo apt-get install lesstif-bin

ps -eaf | grep x-window-manager

to get pid of window manager

kill <pid>

and undecorated window appeared

mwm -display :1.0 &

and window grew motif-like decorations

and typed "date"
