Thank you for the reply,

I have tried the 855resolution program.
	Chipset: 855GM
	VBIOS type: 1
	VBIOS Version: 2880
	Here is the output of version 0.2 for 1024x768

	Mode 34 : 1024x768, 8 bits/pixel
  	(Modeline : 65000 1024 1047 1183 1343 600 697 704 805)
  	(Modeline : 78750 1024 1039 1135 1311 600 692 696 799)
  	(Modeline : 94500 1024 1071 1167 1375 600 692 696 807)


	Mode 45 : 1024x768, 16 bits/pixel
  	(Modeline : 65000 1024 1047 1183 1343 600 697 704 805)
  	(Modeline : 78750 1024 1039 1135 1311 600 692 696 799)
  	(Modeline : 94500 1024 1071 1167 1375 600 692 696 807)

	Mode 54 : 1024x768, 32 bits/pixel
  	(Modeline : 65000 1024 1047 1183 1343 600 697 704 805)
  	(Modeline : 78750 1024 1039 1135 1311 600 692 696 799)
  	(Modeline : 94500 1024 1071 1167 1375 600 692 696 807)

	Version 0.4 gives the same without the mode lines



Based on these modelines would anyone be able to tell me the proper modeline
for xorg.conf? I have tried -

 Modeline  "1024x768" 75.0 1024 1048 1184 1328 768 771 777 806 -hsync -vsync
 ModeLine  "1024x768" 65.0 1024 1048 1184 1344 768 779 785 806
 ModeLine  "1024x768" 65.0 1024 1047 1183 1343 600 697 704 805
 (And a crap load of others)

I can't find anything more out about the LCD screen in the laptop but XP
reports
	Vertical Refresh = 60Hz at 1024x768 32bit
	Font Resolution = 96dpi

Gateway M305CRV (do not but Gateway)
Thanks 
Mark

Hi Mark.

This problems is caused because your bios doesn't list the 1024x768
video mode and i810 driver needs it listed to enable the mode.

To workaround, you will need the 855resolution:
http://perso.wanadoo.fr/apoirier/

This utility enable you to *write* an specific resolution mode to your
in-memory copy of bios so driver is able to find it. I'm using it here
right now to be able to use my native 1400x1050 resolution.

It is very simple to build. Also, you will need to make it run everytime
you boot as the info is lost when shutdown. I added it to my
/etc/conf.d/local.start:

/usr/sbin/855resolution 3c 1400 1050 > /dev/null


The 3c is an unused slot where I can store my configuration. Have a look
at readme inside the tar.gz file to know how it works.



I hope it helps.
