Hi people, huge long time no see. I was wondering if anyone who has a (recent) Linux Distro (like Ubuntu , Linux Mint, etc.) has ever fiddled with /etc/X11/xorg.conf that defines what it outputs from your graphics card. In this case I'm pointing at motherboards that have "intel" graphics, mostly the ones addressed "Intel GMA".

I've the feeling that intel integrated gfx can handle at least 20Mhz or 25Mhz of pixel clock. Said that I was thinking if anyone would like to take the "leap of faith" and mess with /etc/X11/xorg.conf.

The Driver for the "Device" Section should be "intel". It should be something like this:

Code: [Select]
Section "Device"
    Identifier     "Device0"
    Driver         "intel"
    VendorName     "Intel GMA"
    Option         "TearFree" "true"
    Option         "AccelMethod" "sna"
EndSection

In the "Monitor" Section it should have some "super" resolutions that should tell if the intel GMA is capable of 15Khz both progressive and interlaced. Say something like this (Above 25Mhz pixel clock):

Code: [Select]
Section "Monitor"
    Identifier     "Monitor0"
    VendorName     "Unknown"
    ModelName      "Unknown"
    Modeline "1536x224" 25.530 1536 1558 1583 1624 224 236 239 262 -hsync -vsync
    Modeline "1536x480" 27.570 1536 1602 1665 1754 480 506 512 524 -hsync -vsync Interlace
...
EndSection

I hope anyone who has this kind of Mobo's can tell if Intel (GMAs) can at least output 15,Khz with "super resolutions" from the VGA connector (which are nothing more than extended width resolutions for an integer factor to match many games)

If anyone is interested please list your results (on your linux distro) to check if 15Khz for Intel GMA is feasable

Thanks a lot in advance
