am going to bump this cuz ihate my current res, i have tried a look at other forums and faQs i keep getting told to edit my Xorg.config file in X11, but i don't have one (i don,t think 12.04 Lts has one .) but ive even tried to make one and copy and paste , still no good

user9697 10-19-2012 04:54 PM

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

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???

user9697 10-19-2012 10:45 PM

am using an acer 22inch (model x203w) its about 1680x1050

user9697 10-21-2012 04:52 AM

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 ?

JaseP 10-22-2012 03:51 PM

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:

user9697 10-24-2012 11:45 PM

i tried every mode line i can get my hands on, am still getting. xrandr: Configure crtc 0 failed


i don't even know what the next thing is . i can't even get a new board right now if i had enough money :( ....

Hmmm, ... Tried booting with a nomodeset option in grub, vs quicksplash?

user9697 10-28-2012 12:27 AM

no , how would i access the options in grub ??

user9697 11-01-2012 01:26 AM

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
