well i found some one with the same problem on another site and it turned out his EDID info was wrong. so i checked mine and for some reason it can't read the last block. what do you think this could mean ?
Code:
get-edid: get-edid version 2.0.0

	Performing real mode VBE call
	Interrupt 0x10 ax=0x4f00 bx=0x0 cx=0x0
	Function supported
	Call successful

	VBE version 300
	VBE string at 0xc438d "VIA P4M800 PRO
"

VBE/DDC service about to be called
	Report DDC capabilities

	Performing real mode VBE call
	Interrupt 0x10 ax=0x4f15 bx=0x0 cx=0x0
	Function supported
	Call successful

	Monitor and video card combination does not support DDC1 transfers
	Monitor and video card combination supports DDC2 transfers
	0 seconds per 128 byte EDID block transfer
	Screen is not blanked during DDC transfer

Reading next EDID block

VBE/DDC service about to be called
	Read EDID

	Performing real mode VBE call
	Interrupt 0x10 ax=0x4f15 bx=0x1 cx=0x0

The EDID data should not be trusted as the VBE call failed
Error: output block unchanged

You are going to have to define screen resolutions for xrandr...

What are you outputting to as a monitor, and what is it's native resolution???

i finally found the screen name it was default >< so i tried xrandr --addmode default --mode <********> and i got this

Code:
:~$ xrandr --addmode default "1280x1024_60"
xrandr: Failed to get size of gamma for output default

:~$ xrandr --output default --mode "1280x1024_60"
xrandr: Failed to get size of gamma for output default
xrandr: Configure crtc 0 failed
which i think means the modelines am getting from cvt and gtf are wrong , is there another way to get the right one for my screen ?

1680x1050 is the correct resolution for that monitor. Try, "1680x1050_60" with xrandr...

Here is the configuration help page from Ubuntu's wiki for reference;
https://wiki.ubuntu.com/X/Config/Res...s_persistently

One more reference with what are probably your correct modelines:

well i tried to do nomodeset , i used
Code:
 acpi_osi
and
Code:
 acpi_osi="Linux"
both of them got me the same thing, after saving (f10) the comp would go to the os load screen and it was in a higher resolution higher than 1280x1024. but right before the log in screen shows up red text shows up changing really fast i can't read it clearly . then when i boot in the res goes all bad again. but that has happened before without me using nomodeset but ussually instead of the red TXT i get a window telling me am running in low graphics mode but i am unable to do any thing all my input devices don't work . when i restart it goes back to normal. this ussually happens randomly when i restart (sometimes not sometimes yes) . i saw i can set acpi_osi for windows
Code:
 acpi_osi="windows 2006"
this is what al try next if any one has any thing else i can try in grub. like for exapmle i saw a gfx mode setting ... let me kno
