[Novalug] More ? on Ubuntu, ATI drivers and Compaq Presario

[Bonnie Dalzell]

We had a really nasty thunderstorm Sunday afternoon and we had no power 
until last night and no phone (thus no internet) until five minutes or
so ago.

Back to the Compaq 1800T

Well all of you certainly helped me to understand the problem and here is 
what the final solution involved. I had to implement ati in xorg,conf 
after installing the ATI drivers through Applications/Add-Remove. There 
was a page on the internet that I found which had an xorg.conf for the 
Compaq 1800T's LCD screen/monitor.

To get things working I had to try different settings for 
DefaultDepth    under Section "Screen".

I do not know how to change the color depth except to edit that 
number. So I started with 4 and then worked up until 
System>Preferencses>Screen Resolution  would 
not supply the 1024x768 mode as a choice.

Under Ubuntu Hardy it would do a 1024x768 display with a DefaultDepth of 
16 but under Ubuntu Intrepid I had to use DefaultDepth of 15.



here  is my modification of that part of xorg.conf - remember to start 
off with a low value for DefaultDepth:


     Section "Device"
         Identifier  "ati"
         Driver      "ati"
     EndSection

     Section "Monitor"
         Identifier  "Generic Monitor"
         HorizSync   31.5 - 48.5
         VertRefresh 50-70
     EndSection

     Section "Device"
         Identifier	"Standard VGA"
         VendorName	"Unknown"
         BoardName	"Unknown"
         Driver     "vga"
     EndSection

     Section "Screen"
         Identifier  "Default Screen"
         Device      "ati"
     	Monitor		"Generic Monitor"
     	DefaultDepth	15
     	SubSection "Display"
     		Depth		1
     		Modes		"1024x768" "800x600" "640x480"
     	EndSubSection
     	SubSection "Display"
     		Depth		4
     		Modes		"1024x768" "800x600" "640x480"
     	EndSubSection
     	SubSection "Display"
     		Depth		8
     		Modes		"1024x768" "800x600" "640x480"
     	EndSubSection
     	SubSection "Display"
     		Depth		15
     		Modes		"1024x768" "800x600" "640x480"
     	EndSubSection
     	SubSection "Display"
     		Depth		16
     		Modes		"1024x768" "800x600" "640x480"
     	EndSubSection
     	SubSection "Display"
     		Depth		24
     		Modes		"1024x768" "800x600" "640x480"
     	EndSubSection
     EndSection
