How to change screen refresh rate?
How to change screen refresh rate?
Hello.
I am using puppy525.
I want to change the screen refresh rate to 75Hz.
In menu >> setup >> Xorg Video Wizard >> Resolution Changer >> 1280x1024@60.*+
I have also installed "Xorg High -GLX For Radeon and Intel Cards" form QuickPet Drivers.
But still could not find a way to change the refresh rate.
Any help
Thanks.

menu->setup->xorg video wizard->xorgwizard
select probe.
Set resolution.
Select test.
Select test X now.
After test results - select OK.
Select tweak.
Select tweak_xorg.conf
Select tweak_refresh
Scroll up or down ( some selections you will not see without scrolling)
High-lite desired refresh
Select OK
Select test X now.
If you select one that your hardware will not support, it will stall for a few sec. and fall back to last good setting.
Finish xorgwizard

The things they do not tell you, are usually the clue to solving the problem.

This usually means the graphics driver you are using does not support the higher refresh rate for that resolution setting.s3u wrote:I have tried it. But it did not work
The refresh rate still remains at 60HzReport on X test:
Resolution 1280x1024 pixels
Horizontal frequency: 63.98 KHz
Refresh frequency: 60.02 Hz
Video card: intel
Maybe someone with an Intel graphics card can give advice on better driver to use.
What Intel graphics does your computer have?

In Quickpet Driver's tab when I click "Click here to test you graphics card" icon, it gives a message that
Puppy Recommends:
For your Intel video card, Intel Corporation 82Q963/Q965 Integrated Graphics Controller (rev 02) we think the best add on driver is Xorg_High. It would be required for some programs and games with high graphical content and your desktop might seem a bit more snappy. Your selection should be below or there are other versions in PPM and Quickpet

This doesn't guarantee that this linux driver has the capability to drive your card at 75Hz as W7 does.
What is exactly the problem to run at 60Hz?

Sorry for being a console fan, I sometimes find the console more convenient for solving technical problems.
When I want to switch resolutions I tend to use the xrandr program (/usr/X11R7/bin/xrandr). Typing xrandr on its own produces a list of resolutions and refresh rates, e.g on my system typing xrandr produces
The default setting as per above is 1024x768 @ 75.0 refresh rate.
A minimum of 60 and maximum of 87 is available. To change the resolution the command is
The size can be a single integer that relates to the lines that xrandr without arguments outputs. For example 1024x768 is line 0 in the above example.
To change the refresh rate to 1024x768 @ 85, the command is
To change the resolution to 640x480 @ 60 Hz the command is

xrandr only sets the resolution for the current session, AFAIK some versions of PuppyLinux allow the xrandrshell (a graphical front-end to xrandr) utility to store resolutions which are stored somewhere in the /etc folder. I used to use it to keep resolutions between restarts of Xorg/Xvesa when using a live CD.
There is a nifty looking utility similar to xrandrshell shown in Barry Kauler's blog at http://bkhome.org/blog/?viewDetailed=01881
It is also possible to edit /etc/X11/xorg.conf to set resolution & refresh rate if you know what you are doing.

Peterm321,
Not sure if your method really works for all video cards.
I can use xorgwizard to select 1280X1024 @ 60 HZ
And it seems to give me that.

As you can see below. My xrandr does not even show that 60HZ refresh option.
Graphics card adjustment and driver selection is a black art. Nothing ever seems to be a simple answer.

I can't give authorative advice because configurations vary from system to system. I take it as read you have made sure that it is Xorg (not Xvesa) that is being run. If you are not 100% sure Check
ls -l /usr/X11R7/bin/X
there is also a utility called ddcprobe which returns information about the video and display resolutions. On my system it is located at
/usr/sbin/ddcprobe
With reference to Xorg I would search the Internet for the search string "xorg.conf" +<your graphics card> [ to find sample xorg.conf files for your configuration].
and
"xorg.conf" +<your monitor model>
The video display unit model number may be relevant particularly if it is a CRT.
NB there is also a section in /etc/X11/xorg.conf to tell Xorg what refresh rates the video monitor uses, for me it is:
Code: Select all
Section "Monitor"
# HorizSync source: xconfig, VertRefresh source: xconfig
Identifier "Monitor0"
VendorName "Unknown"
ModelName "CRT-0"
HorizSync 30.0 - 70.0
VertRefresh 50.0 - 120.0
Option "DPMS"
