Ubuntu 8.04 display resolution story

Screen One week ago, I brought some old hardware from my parent’s to my flat in Seville. I brought an old router, some network wires, a Pentium IV, etc. However, here I only have a SVGA screen and this CPU was connected and configured to work at 1024×768.

Once I turned the machine on, I realized that Ubuntu doesn’t reconfigure itself when a new monitor is attached. So I understood I would have to change this by hand.

In first place, I thought of changing xorg.conf file, but there was not anything like “Display” subsection. It seems Gnome/Ubuntu 8.04 does not care about xorg.conf.

Reading some forums on the Internet, I was prompted to run “dpkg-reconfigure xorg-xserver”, but it seems that this only reconfigures my keyboard. “X -configure” did either.

Later, after so many tests, I thought that it may be stored in a different place. So I asked one friend for some hints (he is an KDE enthusiast) and finally located a file called “monitors.xml” under “/home/$home/.gnome2/”. I replaced 1024 by 800 and 768 by 600. (See highlighted lines) and rebooted. Later everything ran okay.

Contents of monitors.xml:

<configuration>
<clone>yes</clone>
<output name=”DVI-0″>
</output>
<output name=”S-video”>
</output>
<output name=”VGA-0″>
<vendor>TAT</vendor>
<product>0xcfbb</product>
<serial>0×0030feba</serial>
<width>800</width>
<height>600</height>

<rate>60</rate>
<x>0</x>
<y>0</y>
<rotation>normal</rotation>
<reflect_x>no</reflect_x>
<reflect_y>no</reflect_y>
</output>
</configuration>

I hope this helps.

    I installed Gnome on that machine as a Windows replacement. However, right now it is my Minix development box and I seldom open Gnome. Once I am finished with Google summer of code, I’ll get rid of Gnome from that computer.

    P.S: post updated pointing to your blog.

    If you do not know how to set it up in control panel, you can start your computer in Ubuntu Restore mode, and it will reset for your new display card.

    @Mark: I tried that too, but it didn’t work for me.
