== Ubuntu 5.10 (Breezy) ==

The drivers for the i915 (or similar) chipset are not available neither in Hoary, nor in Breezy.

As a result, GDM might not be able to reach the maximum resolution.

Steve Tomljenovic provides a very nice workaround for this, called '''915resolution'''.

It is available from: http://www.geocities.com/stomljen/

All I had to do was:

 1. Download ''915resolution''

 2. run ''"915resolution -l"'' as root

 3. Pickup an unused resolution ('3c' for me)

 4. run ''"915resolution 3c 1400 1050 32"'' as root

 5. Edit ''/etc/X11/xorg.conf'' to add

{{{
Option "ForceBIOS" "1920x1440=1400x1050"
}}}

and check if the driver is right ('''"i810"''').

As a result, the ''/etc/X11/xorg.conf'' looks like: {{{
<SNIP>
Section "Device"
        Identifier "Intel 915GM"
        Driver "i810"
        BusID "PCI:0:2:0"
        VideoRam 65536
Option "ForceBIOS" "1920x1440=1400x1050"
EndSection

Section "Monitor"
        Identifier "Generic Monitor"
        HorizSync 28-72
        VertRefresh 59.0 - 75.0
        Option "DPMS"
EndSection

Section "Screen"
        Identifier "Default Screen"
        Device "Intel 915GM"
        Monitor "Generic Monitor"
        DefaultDepth 24
        SubSection "Display"
                Depth 24
                Modes "1600x1200" "1400x1050" "1280x1024" "1024x768"
        EndSubSection
EndSection

<SNIP>

Section "DRI"
        Mode 0666
EndSection
}}}

 1.#6 make ''915resolution'' run on every boot, before starting X:

add to ''/etc/init.d/bootmisc.sh'', before "exit"

{{{
/usr/sbin/915resolution 3c 1400 1050 32
}}}

 1.#7 restart the system or restart X (using Ctrl+Alt+Backspace + "''startx''" at the command prompt)

For further information:

== Ubuntu 6.06 (Dapper) ==

 1. enable 'community maintained' (universe) repository from the Synaptic package manager or modifying the file etc/apt/sources.list (apt sources list)

 2. install 915resolution:
{{{
# sudo apt-get install 915resolution
}}}

 3.#3 follow instructions contained in {{{/usr/share/doc/915resolution/README.Debian}}}
