How i change Xorg resolution to 600x600

[malikawan]

Thanks alot nitram. if you dont mind please give me xorg.conf file which change the resolution to 800x600 and refresh  rate 75. so i will copy this file to core.gz by extract it. Just need xorg file which change the resolution for my requirement. I have tried to change but its not work if you do for me i shall be very thankful to you.

[nitram]

Tried to explain, xorg.conf file can be hit or miss, requires tinkering. You may want to test with method described above before creating new *.gz. This is what i would try first, change intel to what you're using. If you want 24 bit colour, change 16 to 24.

Code: [Select]

Section "Monitor"
Identifier   "Monitor0"
HorizSync       28.0 - 96.0
VertRefresh     50.0 - 75.0
EndSection

Section "Device"

Driver      "intel"
EndSection

Section "Screen"
Identifier "Screen0"
Device     "Card0"
Monitor    "Monitor0"
SubSection "Display"
Depth 16
Modes   "800x600_75"
EndSubSection

but my hardware support 75 Hz. i read the manual

What is the Maximum Screen Resolution for the PXI Controllers?
Hardware: PXI/CompactPCI>>Controllers>>PXI-8106
Problem:
I want to connect a high resolution monitor to my PXI controller, what is the maximum resolution the controller can display?
Solution:
The following controllers can display a maximum of 2048x1536 pixels at 75 Hz on both analog and digital displays.
    PXI-8101
    PXI-8102
    PXI-8104
    PXI-8105
    PXI-8106
    PXI-8108
    PXI-8110
    PXI-8133
I am using PXI-8102

[malikawan]

I am using PXI-8102 using
The Mobile Intel GM45 Express Chipset
(Graphics and Memory Controller Hub) connects to the CPU, DDR2 SDRAM, and DVI-I video

I read from Xorg-log-0 and find that no intel module found so it load vesa module. please any idea

[Juanito]

load xf86-video-intel

What do you get when you issue the xrandr command without arguments?

For example:

Code: [Select]

$ xrandr
Screen 0: minimum 8 x 8, current 1366 x 768, maximum 32767 x 32767
eDP1 connected 1366x768+0+0 (normal left inverted right x axis y axis) 277mm x 156mm
   1366x768       60.0*+   40.0 
   1280x720       60.0 
   1024x768       60.0 
   1024x576       60.0 
   960x540        60.0 
   800x600        60.3     56.2 
   864x486        60.0 
   640x480        59.9 
   720x405        60.0 
   680x384        60.0 
   640x360        60.0 
DP1 disconnected (normal left inverted right x axis y axis)
HDMI1 disconnected (normal left inverted right x axis y axis)
HDMI2 disconnected (normal left inverted right x axis y axis)
VIRTUAL1 disconnected (normal left inverted right x axis y axis)

Once the intel video driver is loaded and you look at Xorg.o.log, do you see something like this:

Code: [Select]

[  3020.100] (II) intel(0): switch to mode 1366x768@60.0 on eDP1 using pipe 0, position (0, 0), rotation normal, reflection none
[  3020.100] (II) intel(0): Setting screen physical size to 361 x 203
I'm not sure, but if you have a monitor connected rather than an lcd, I believe Xorg will query it to see what video modes are supported - if your monitor and xrandr do not show 600x600@75Hz, I believe you will be out of luck.

[malikawan]

After load xf86-video-intel
Xrander output:--
Screen 0: minimum 320 x 200, current 800 x 600, maximum 8192 x 8192
LVDS1 connected (normal left inverted right x axis y axis)
   1024x768       60.0 +
   800x600        60.3     56.2 
   640x480        59.9

   1024x768       60.0 
   800x600        60.3*    56.2 
   848x480        60.0 
   640x480        59.9 
HDMI1 disconnected (normal left inverted right x axis y axis)
DP1 disconnected (normal left inverted right x axis y axis)

Any idea please

..Xorg does not believe your graphics hardware or your monitor support 600x600 - therefore, I do not think you will be able to get it using Xorg.

Sorry i just need to increase refresh rate using 800x600. i know that my hardware support 75 Hz So i just need 800x600 with refresh rate 75 Hz

[Juanito]

Did you try the xorg.conf suggested by nitram above?

[malikawan]

Yes i have extract core.gz and copy same conf file to /etc/X11 with name xorg.conf.vesa and pack core.gz but still no result........
