View Full Version : [ubuntu] VNC - unable to do anything... just view

May 10th, 2009, 12:50 PM
I just configured a VNC server on my Ubuntu 9.04 64bit, and it "seems" to be working.
When I connect to it from a VNC viewer, I'm able to see the desktop and all of the items, but when I click with the mouse/keyboard on anywhere, it doesn't seem to do anything.
The strangest thing is that when I'm it does the change, but I'm unable to see it in the VNC viewer.
If I'm near my desktop I see all of the actions I remotely in the local machine, but I don't see it from the VNC viewer.

Any idea what the problem is and how can I resolve it?

Thanks in advance.

It's a known issue with 9.04

Turn off compiz and it'll update correctly.

Here's a script someone else wrote that works to change this on the fly:

compiz=`pidof compiz.real`
metacity=`pidof metacity`
metacity_composide=`gconftool -g /apps/metacity/general/compositing_manager`

if [ -z $compiz ]; then
echo "Debug: Compiz is deactivated"
gdialog --yesno "Current Window-Manager: Compiz\n\nStopping Compiz and starting Metacity."
if [ $? = 0 ]; then
metacity --replace
##If you want to use Metacity Composite, uncomment the next line
# gconftool-2 -s --type bool /apps/metacity/general/compositing_manager true
if [ -z $metacity ]; then
echo "Debug: Metacity is deactivated"
gdialog --yesno "Current Window-Manager: Metacity\n\nStopping Metacity and starting Compiz."
if [ $? = 0 ]; then
if [ "$metacity_composide" = "true" ]; then
gconftool-2 -s --type bool /apps/metacity/general/compositing_manager false
compiz --replace
compiz --replace

exit 0

Hope this helps.

Can I make compiz to be automatically disabled when VNC connection is made?

It's more of a permanent solution, but try:

metacity --replace

Ive done the proposed (disable compiz) and it worked for a while, but now I have restarted my machine and the it is happening again (compiz is disabled) and I'm connecting from a Ultra VNC windows machine.

Any ideas?

I ran the script on my Ubuntu 9.04 64 bit server that was running compiz and I now have screen control. I was pleased that compiz automatically restarts when I log out and back on. Thank you for this advice.

I think it's something with the graphics driver. Try to disable your driver and see if it works. This helps for me.
I haven't found a solution for this.
Update: Net yet tested, but try to disable the visual effects

This is exactly what I have been looking for. I am a little new to linux, so I just have one question where would I actually put that script. Any information would be gladly appreciated. Thanks
