Can not set up the resolution with xorg (solved )

[james_liu]

Change the resolution null and void, no matter what I set the value, such as 1024x768 or 800x600, It always displayed as a screen resolution of the biggest 1280x1024.
My chipset is intel 945gm, and Puppy is 400. How to solution it? Thansk for any help!

Thank you for your reply, I will try this way.
Can tell me why when I run xorgwinzard to choose any screen resolution when, xsever always automatically set to the largest screen resolution?

the intel chips seem to ignore the resolution in xorg.conf, as the resolution is set in the graficscard.
So you must use instead "915resolution".
That utility seems to set the resolotion in the graficscard itself.

According to the http://www.murga-linux.com/puppy/viewtopic.php?t=32462 said, every time I have to use 915resolution set to start in resolotion before startx.
Really need it?

[MU]

yes, I think so.

Readme from Muppylinux:

915resolution sets a video bios mode for intel graficscards.
It must be run before X starts.

For example add a line like this to /etc/rc.d/rc.local

915resolution 45 1024 600

(mode width height)

use:
915resolution -l
to see available modes

I found in my xorg.conf contains the following lines:

Code: Select all

Section "Monitor"
	#DisplaySize	  340   270	# mm
	Identifier   "Monitor0"
	VendorName   "BNQ"
	ModelName    "BenQ FP71G"
	### Comment all HorizSync and VertRefresh values to use DDC:
	Option	    "DPMS"
	HorizSync    31.0-83.0
	VertRefresh  56.0-72.0
	#UseModes     "Modes0" #monitor0usemodes
	Option      "PreferredMode" "1024x768"
	EndSection
	
Section "Modes"
	Identifier "Modes0"
	#modes0modeline0
EndSection

The "UseModes" is not set. Is it because of intel ignored to write resolution to xorg.conf?

[james_liu]

Can I write the "Modes" to xorg.conf and set it to take effect?

[MU]

the modes can set very specific things for the monitor, like frequencies.
For LCD monitors, this usually is not needed, only for few models, that cannot sync with the graficscard by default.

To set the permanent resolution, you must edit /etc/rc.d/rc.local as written in the readme.

Do not have any way to replace the 915resolution? For example, by modifying the xorg.conf, after all, hardware platform will not change/

[james_liu]

The resolution question I had already solved, the question left in screen refurbishing rate. It is not unnecessary to use 915resolution.
modify xorg.conf:
change

Code: Select all

HorizSync         31.0-80.0
VertRefresh      50.0-72.0

to

Code: Select all

HorizSynv         31.0-50.0
VertRefresh      40.0-72.0

then restart x,the resolution is changed to your hoped.
Thanks MU once more !
