Resolution problem without "xorg.conf" nor "dpkg --configure -a"

**iperetta** · January 10th, 2010

Hi, there

I'm a beginner with Linux, but I could find myself several times by now. I recently have installed Ubuntu 9.10. The fact is, it hasn't recognized my monitor (a Philips 105E) and it get me stuck with 800x600 unknown monitor. When I try to solve my resolution problem, first I've looked for "xorg.conf" file:

Code:

igor@RatZ:/etc/X11$ ls /etc/X11/
app-defaults             fonts    xinit       Xsession          XvMCConfig
cursors                  rgb.txt  xkb         Xsession.d        Xwrapper.config
default-display-manager  X        Xresources  Xsession.options

And I didn't find it. Next, I've tried "sudo dpkg --configure -a":

Code:

igor@RatZ:/etc/X11$ sudo dpkg --configure -a
[sudo] password for igor: 
igor@RatZ:/etc/X11$

And nothing's happen. Then, I've tried to find out what Ubuntu has detected:

Code:

igor@RatZ:/etc/X11$ lspci |grep -i vga
00:02.0 VGA compatible controller: Intel Corporation 82G33/G31 Express Integrated Graphics Controller (rev 10)
igor@RatZ:/etc/X11$ xrandr
Screen 0: minimum 320 x 200, current 800 x 600, maximum 4096 x 4096
VGA1 connected 800x600+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
   800x600        60.3* 
   640x480        59.9

So, what I got to do or what do I need to update/install to solve my resolution problem?

Thank you for support!

Uff! Finally!

I was really hard to understand how to do it, but I did, thanks to http://ubuntuforums.org/showthread.p...lution+problem.

To make it short (take note because it will change to terminal mode, you'll loose desktop):

Start a terminal. Enter with

Code:

sudo service gdm stop

It'll ask for user and pwd

Code:

sudo Xorg -configure

It'll create a xorg.conf.new in /home/yourself

Code:

sudo service gdm start

Now, start a terminal. Enter with:

Code:

sudo mv /home/yourself/xorg.conf.new /etc/X11/xorg.conf
sudo gedit /etc/X11/xorg.conf

Inside the file, search for << Section "Monitor" >> and make it closer to:

Code:

Section "Monitor"
        Identifier   "Monitor0"
        VendorName   "Monitor Vendor"
        ModelName    "Monitor Model"
        HorizSync AA-BB
        VertRefresh CC-DD
        #UseModes     "Modes0" #monitor0usemodes
        Option      "PreferredMode" "1024x768"
EndSection

Where AA-BB and CC-DD are based on your monitor manual (mine, I found in the manual under Technical Specifications/ Scanning/ Horizontal scanning & Horizontal scanning).

In the same file, search for << Section "Screen" >> and make it closer to:

Code:

Section "Screen"
       Identifier "Screen0"
       Device     "Card0"
       Monitor    "Monitor0"
       DefaultDepth 24
            # (...)
       Subsection "Display"
       Depth       24
       Modes       "1024x768"
       EndSubsection
EndSection

Then, do it again:

Code:
