I updated one of our servers to Ubuntu 11.10. Previously We were using CentOS 6.1. When using CentOS I was able to connect to it using VNC Viewer from Windows 7 Machines. But after installing Ubuntu 11.10, when I connect, I can connect and view the Desktop, but there is nothing on the Desktop. No menus, or gadgets can be seen. If I try to invoke some GUI like
gedit Its giving me an error
Xlib: extension "RANDR" missing on display ":0"
Keyboard inputs also does not work properly. When I pressed
d key on keyboard it minimized the terminal window. I can't understand what is happening. Is there any solution for this?
