My Ubuntu 10.04 shuts itself down low on graphics

[Langjan]

Ubuntu shuts itself down and displays message that it is running low on graphics, giving me options to run in low graphics mode or to troubleshoot. I have been given the following advice but have no idea what to do:

You are using the open driver i915 as you are using an intel based video
chip.

Sounds like you need an xorg.conf file to define the display a little better as udev is not detecting. Here is a sample file you can start with: (Refers to a URL that led me to this forum)

You can ignore any sections and entrys regarding keyboards as udev is
pretty awesome at picking those up

lspci | grep -i vga
00:02.0 VGA compatible controller: Intel Corporation 82G33/G31 Express Integrated Graphics Controller (rev 10)

Cannot find /etc/X11/xorg.conf

Press Alt+F2 and type this

gksu gedit /etc/X11/xorg.conf

It will open xorg.conf file in Gedit with root privileges.

Delete all contents of xorg.conf file, if there are any. Copy following contents and paste in xorg.conf file :

Section "Device"
       Identifier "Configured Video Device"
       Driver    "i810"  
EndSection

Section "Monitor"
         Identifier "Configured Monitor"
         HorizSync 31.5 - 70.0
         VertRefresh 50 - 160
 EndSection

Section "Screen"
        Identifier "Default Screen"
        Monitor "Configured Monitor"
        Device "Configured Video Device"
        DefaultDepth 24
        Subsection "Display"
             Depth 24
             Modes "1280x1024" "1024x768" 
        EndSubsection
EndSection

Save file and reboot machine.

Many thanks. The restart/shut down works now, but I receive the following message on restart:

Ubuntu is running low in graphics mode. The following error was encountered:
You may need to update your configuration to solve this.
(EE) Failed to load module "i810" (module does not exist, 0)
(EE) No drivers available

Then I select the option to run Ubuntu in low graphics mode for one session and everything seems to run fine.

Replace "i810" with "intel" in /etc/X11/xorg.conf file.

Section "Device"
       Identifier "Configured Video Device"
       Driver    "intel"  
EndSection

In case it doesn't work, replace it "intel" with "vesa".
vesa is a generic driver and works fine with most of Graphics Cards.

Thanks, I have implemented all of these suggestions but the problem persists.

How much memory you have allocated for video in BIOS setup.

[Langjan]

Have not allocated anything, unable to locate video settings in bios setup, where do I find these?

Error message now being received is:

(EE) VESA: kernel modesetting driver in use, refusing to load
(EE) no drives detected

[devils casper]

Remove Driver line from xorg.conf file.

       Identifier "Configured Video Device"
