I845 video chipset

[Desquerre Yohann]

Hi all,

Speaking about the video driver, is there any one which manage to make
work an i845GL chipset up to 1020*868... I would very happy to kown that
!!!

thanks

1020x868?  What an oddball resolution.  ;o)

Seriously though, the horiz width and line pitch has to be a
multiple of 8 pixels.

[mharris@devel X86]$ gtf 1020 868 75

# 1024x868 @ 75.00 Hz (GTF) hsync: 67.95 kHz; pclk: 93.50 MHz
  Modeline "1024x868_75.00"  93.50  1024 1088 1200 1376  868 869 872 906  -HSync +Vsync

There's 1024x868@75Hz, about as close as you can get to 1020 
horiz.

My problem to use 1152*864, my /etc/X11/XFree86config file seems to be
correct but Xfree always chose 1024*768...

Snif... I 'm so sad..

however thanks for your additional information.

A part of me XF86config file :

"Section "Device"
        Identifier  "Videocard0"
        Driver      "i810"
        VendorName  "Videocard vendor"
        BoardName   "Intel 845"
EndSection

Section "Screen"
        Identifier "Screen0"
        Device     "Videocard0"
        Monitor    "Monitor0"
        DefaultDepth     24
        SubSection "Display"
                Depth     24
                Modes    "1152x864" "1024x768" "800x600" "640x480"
        EndSubSection
EndSection
"

Check your X server log file, and it will tell you why it 
rejected 1152x864.  A popular reason for Intel video hardware, is 
because your BIOS CMOS settings limit the video memory to a small 
amount like 1Mb or 2Mb.  Increase the video memory amount in the 
BIOS to 16Mb or more.  Alternatively try using VideoRAM 16384 in 
the config file Device section.

If you are talking to me about the "on chip frame buffer size", it's
limited to 8MB ???

I tried that no success (moreover my chipset have got 64Mo(i tried it
with Win... Xp : Shame on me)).

I didn't say there'd be any error messages or warnings.  There is 
at least 4 or 5 screens or more full of X server startup 
information though, and part of that information is a complete 
detailed listing of every single video mode known to the X server 
and wether it was accepted, or rejected, and if rejected - why it 
was rejected.  That's the information you're looking for.

That's the one.  If you can't set it above 8Mb I recommend 
disabling DRI.
