- I installed Ubuntu 11.10 amd64 and it used the default settings and vga driver : unknown both screens sere working regardless of the errors of turning the laptop's off then both go off forever!
- so I tried installing nvidia driver in both ways, I. from the additional drivers current-driver way and II. the manual:
sudo service lightdm stop
sudo sh Nvidia..._.run
sudo service lightdm start
both had the same results,
in system info : Graphics : UNKNOWN , in display settings : one UNKNOWN display is detected "the laptop's" and cannot detect my other display
what i did is that i modified the display's settings from nvidia settings as a root in order to save the settings
LG Display > enabled , res : 1920- 1080 , 60hz , left of (separate display options)
Laptop Display > right of
now the external screen can turn it's lights on but not useful at all i can't make it the default primary screen nor i can use it as primary if i disable the laptop's the other turns off along with it
I believe if the Graphics : unknown problem is solved then all is solved the system doesn't recognize the driver as if it is on it's own
nvidia admins said it is a problem of the system not the driver
"it was working properly with ubuntu 10.04 with nvidia manual driver installation"
