Here I have a host with Windows XP Pro SP3 (32-bit) 4GB RAM. On different other PC's I installed Ubuntu 8.10 and 9.04 (64-bit as a host) with 8GB RAM.
When I installed a guest with Ubuntu. The Problem occurs from start of Version 8.10 I think.
I only install openssh-server and x11vnc which I use to get a login screen after a reboot. I only connect to this machines via PuTTY and tightvnc from Windows machines over the network or internet.
This works fine. But after installing the Guest additions the right mouse click won't work anymore. I reported that in Ubuntu Forums and discussed with the author of x11vnc.http://ubuntuforums.org/showthread.php?t=1264443&page=3
Posted a logfile and did a view tests, somethings going wrong when I install the GA.
But, I thought i have to live with it and have now the other Problem with the resolution. As I did this with older Versions 7.04 until 9.04, editing the xorg.conf worked.
But Now nothing happens after editing xorg.conf, even it kills the gnome desktop.
After this I only can log in in terminal mode and that's it's, now gnome desktop etc.
That's why I'm asking for this solution. But in this moment i have a idea. maybe i can install old VESA display drivers in the VM via synaptic ? These should help me with only 1024 I hope. Or is there a way to only install the GA display driver ?
And as I'm writing. Another Problem after the guest additions was that the resolution was very small and strange, couln't set another like 1024x768. But I could resize the tightvnc viewer like I want. this worked.
