[SOLVED] screen resolution ubuntu 9.10

[daemon52]

hi all
I am having a problem with the screen resolution, unable to get above 800x600. I have tried various things suggested on this forum, including editing xorg.conf ( twice needing a visit to the recovery console) all to no avail. I know the monitor(Yuraku MJ7CNA) is capable of 1280x1024 but that option is not in the display settings.
lspci gives me

Try using "via" driver and if it doesn't work, use "vesa" driver.
Check Monitor's Manual for supported HorizSync and VertRefresh rates.

Section "Device"
	Identifier	"Configured Video Device"
	Driver		"via"
	BusID		"PCI:1:0:0"
EndSection

Section "Monitor"
	Identifier	"Generic Monitor"
	Option		"DPMS"
	HorizSync	30-71
	VertRefresh	50-160
EndSection

Section "Screen"
	Identifier	"Default Screen"
	Device		"Configured Video Device"
	Monitor		"Generic Monitor"
	DefaultDepth	24
	SubSection "Display"
		Depth		24
		Modes		"1280x1024" "1024x768" 
	EndSubSection
EndSection

Section "ServerLayout"
	Identifier	"Default Layout"
	Screen		"Default Screen"

thank you so much . the via driver wrecked the display but the vesa driver added both new resolutions to the display preference panel and i was able to set the correct resolution.
my friend...you walk on water..thanks again
