- 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
sudo nvidia-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"
Hardware info: computer type: laptop, type: ASUS f8sn, CPU 2. 4 core 2 due T8300 santarosa penryn, vga: Nvidia geforce 9500m gs, motherboard: ASUS, bus: Intel, chipset: Intel, external screen: LG E 2205, DVI connector: DVI-D Single link
I posted this after maybe the 15th reformat and reinstall of Ubuntu to fix this problem
