Problem with display

[abelito8]

Hi there,

I installed Kubuntu 9.10 on an Acer Aspire One 160 GB HDD and 11" screen but the definition I have is not ideal for my screen (whose size is not even recognised by the system). If I go to setting>display it gives me only one option, the current one

Am I missing a driver?

Execute this in Terminal :

sudo lspci | grep -i vga

Post the output here.

Post the contents of /etc/X11/xorg.conf file here, if any.

Thanks
that's unexpected, I have typed the command in the alt-F2 window and in the terminal....
and the system refuses to open it (it demands the password and then fails to start it)....

I have restarted the computer but nothing...

I am lost, anything I can do?

[elija]

In the ALT + F2 window, enter the command

gksu gedit

Enter your password

Open /etc/X11/xorg.conf

[abelito8]

The problem was that gedit was not included in the install I made...as far as I knew it was in by default...once I found out I just had to install it and it worked, now I just have to find the ideal resolution. Thanks

You can try any text editor like nano, pico or vi.
