Screen resolution???

JNaas · 05-27-2005, 08:14 PM

Hi all!

I'm new to Ubuntu, and so far i am pretty happy with it!
I've been able to do all the things i've told it to!

but during install i had to choose screen resolution and i just chose dafault 1024x768 but my screen is a wide-screen and are able to go to resolution 1200x800 wich i saw in that list during install(butt didn't pay much attention to!)

Now i would like it to go to that resolution, but the max I'm able to choose is 1024x768... So i assume that the thing i did during install was to define the maximum resolution that my screen is able to show!!

and now the question!: how do i redefine the max resolution that it is possible to show on this screen?

THX Jnaas!

You could try editing manually your xorg.conf. That feature on Ubuntu does not work very well, or so I've learned. Well, open a terminal and type:

sudo nano /etc/X11/xorg.conf

Find a line called "Screen Resolution" in that file. Here is an example:

Code:

Section "Screen"
	Identifier	"Default Screen"
	Device		"NVIDIA Corporation [GeForce FX5200]"
	Monitor		"Generic Monitor"
	DefaultDepth	24
	SubSection "Display"

As you see, my computer is set to start at a default of 24 bits color dept. So looking down a little further, I find:

Code:

	SubSection "Display"
		Depth		24
		Modes		"1280x1024" "1024x768" "832x624" "800x600" "720x400" "640x480"
	EndSubSection

That's how xorg will try to initialize. When xorg file is executed, it will start at 24 bits mode and try 1280x1024. If it fails, it will try 1024x768, and so on. Basically, add the resolution you want at the beginning of that line. Eg:

Code:

	SubSection "Display"
		Depth		24
		Modes		"1200x800" "1024x768" "800x600"
	EndSubSection

The above should work fine. Save that file (ctrl + o to save and ctrl + x to quit). Restart X and hope for the best

That may work. What I had to do to get 1024 x 768 (as opposed to 800 x 600) was also find out (from my monitor's manufacturer's website) what the HorizSync and VertRefresh rangers were (this is also within the xorg.conf file).
