How to get 1280x800 on intel 855GM


Hey all, I recently Just fixed the resolution on my Laptop, so i am going to tell u how .

Slackware was not letting me increase my resolution any higher than 1024x768, and the resolution i wanted was 1280x800. I had spent a long time trying to work out how to do this.
I tryed editing my /etc/x11/xorg.conf file, but it just didn't like any resolution above 1024x768.
So this is what i did: (btw any newbies out there, DON'T worry it is very easy )



1: + Download the program 855resolution from: perso.wanadoo.fr/apoirier/
+ Unpack: tar -xvzf 855resolution-0.4.tgz
+ Enter directory: cd 855resolution
+ Install:

make
su
make install

###
#Now the program is installed we have to make sure it runs everytime your reboot.
###


2: + Open "/etc/rc.d/rc.local" in your favourite text editor. (should be quite empty)
+ add the following line:


# The following sets the "3c" VBIOS mode to 1280x800
855resolution 3c 1280 800


+ Save, and quit.


###
#And finally, editing your "/etc/X11/xorg.conf" file
###

3: you only have to edit your "Modeline" and "resolutions".

To make this easier, i am going to paste my xorg.conf file below.
The bits in RED are what i edited (they about 4/5's of the way down the script, so keep scrolling down ):

+ So now that you have done that you can now reboot and start your X server and you should have your 1280x800 resolution.. enjoi!!

Useful post. I used the same trick to get my 1280x800 wide screen resolution working on SUSE 9.2 Professional. But why it doesn't work on Fedora Core 3 and 4?

A better way:

First, you should make sure the monitor supports the resolution at the refresh rate you want. I went to windows and looked at those settings to make sure I had the right settings. Then go to the X Modeline Calculator and enter the values into the form (all you really need to enter are width x height and refresh rate, leave the rest blank). It will then give you a modeline. put this modeline in your Monitor section of the xorg.config file. Now put "1280x800@60" (or whatever the modeline is called) in the Display section. This should work.

Here is part of my xorg.conf

Code:
Section "Monitor"
	Identifier   "Toshiba LCD"
	HorizSync    31.5 - 64.3
	VertRefresh  50.0 - 90.0
	Modeline "1280x800@60" 83.91 1280 1312 1624 1656 800 816 824 841
EndSection

Section "Device"
	Identifier  "Intel Extreme"
	Driver      "i810"
	ChipSet     "852GM/855GM"
	Card        "i810 852GM/855GM"
EndSection

Section "Screen"
	Identifier "Screen"
	Device     "Intel Extreme"
	Monitor    "Toshiba LCD"
	DefaultDepth     24
	SubSection "Display"
		Viewport   0 0
		Depth     24
		Modes    "1280x800@60"
	EndSubSection
EndSection
as you can see I only have one resolution mode defined...it's the only one I use anyway.

For Fedora core, I think it remembers the previous resolution you were using, so you'll have to either:

A) switch resolutions (there is a key combination, but I can't remember it)
or
B) remove all other modes from xorg.conf. If you want the options of the other modes, just put them back in after you start x at least once.
