Video resolution

[FabioBraso]

Hello.

I'm new in Linux world.

I installed ubuntu 9.10 in PC with pentium III 933MHz, 512Mb RAM and Matrox G400 32Mb video card.

There is a small problem with video resolution.
Ubuntu doesn't allow me to setup a resolution higher than 800 x 600.

Can someone help me?

Thank you

Fabio

I've got a similar problem, got an intel 910gl integrated graphics card. Stuck on 800x600 resolution. I think the solution involves making an xorg.conf file (since I don't seem to have one/or an empty xorg.conf) and inserting some values into it, though i am unsure of the exact procedure.

Thank you for your interesting,

I had check in folder /etc/X11 but there isn't xorg.conf file.

How can i create it?

Thank you

To create empty xorg:

sudo gedit /etc/X11/xorg.conf (save & close)

configure it:

sudo dpkg-reconfigure xserver-xorg

have a look here:

that link should solve anonymous1986's problem because it is also intel.

Hello Temüjin,

Here attached the log filese.

Your problem...

(WW) MGA(0): Unable to estimate virtual size
...
(--) MGA(0): Virtual size is 800x600 (pitch 800)

So specify the virtual size manually in your /etc/X11/xorg.conf so the file looks like:

Section "Device"
        Identifier      "Configured Video Device"
EndSection

Section "Monitor"
        Identifier      "Configured Monitor"
EndSection

Section "Screen"
        Identifier      "Default Screen"
        Monitor         "Configured Monitor"
        Device          "Configured Video Device"
        SubSection "Display"
             Virtual 1280 1024
        EndSubSection
EndSection
