16:10 with a Intel 900GMA

Hi !

  I have a desktop with an onboard Intel 900GMA graphic card and a 16:10 LCD Flat Panel.  I want to have a 1280:800 resolution (or anything 16:10 would do actually), but when I set it and run X, I got a different resolution and most of all, I have to drag my mouse to the screen border to see an hidden part of the screen (like if I was zoomed in).

Here a part of my xorg.conf:

Section "Monitor"
  ...
  HorizSync 64.6
  VertRefresh 59.9
  Option "DPMS"
  DisplaySize 433.4 270.9
EndSection

Section "Device"
  ...
  Driver "i810"
  ...
  Option "Accel" "true"
  Option "DRI" "true"
EndSection

Section "Screen"
  ...
  DefaultDepth 16
  SubSection "Display"
    ViewPort 0 0
    Depth 16
    Modes "1280x800"
  EndSubSection
EndSection

Section "DRI"
  Mode 0666
EndSection

I used the official spec of my monitor for the refresh rate and the screen size.

Thanks a lot for your help !

PS: Forgot to mention that I use arch64 ... but suppose that it's the same as archLinux.  I have an archLinux install on my laptop, and I get everything right and the same screen, but with an nVidia driver ... so the problem really seem to be from the i810 driver.

Re: 16:10 with a Intel 900GMA

You probably need 855resolution or 915resolution to be run before starting xorg (e.g. from /etc/rc.local or xinitrc). Search the forums or read the docs for these utils for detailed description.

EDIT: and if you would like to have correct resolution for the console too use kernel26beyond because it has vesa tng and you can specify 1280x800 as the resolution too.

I've got 16:10 on my Dell LCD, unfortunately it uses 1680x1050 but maybe the thread is useful for you.

Passing

video=vesafb,1280x800-8

to the kernel at boot time should put your framebuffer at 1280x800x8 bit. I've tried it with 1680x1050 but it doesn't work even though it should. I don't even get a warning or error or anything.

If you use a different framebuffer driver than vesafb, you probably need a different boot argument.

I'm using this in my /boot/grub/menu.lst

title  Arch Linux Beyond (vesafb)
root   (hd0,1)
kernel /boot/vmlinuz26beyond irqpoll video=vesafb:ywrap,1280x800-24@60 root=/dev/sda2 ro
initrd /boot/initramfs-beyond.img

This assuming that you're running kernel26beyond or your own kernel patched for vesa-tng.

1280x800 may possible not a mode in the vbe, nor does it look to me that this resolution is vesa compliant.

Re: 16:10 with a Intel 900GMA

I tried the 915resolution solution, and everything is Ok now !!! Thanks a lot lanrat !!! Your help has been really appreciated !!!

Thanks for your help too FUBAR, but my Xorg.conf file was correctly configure, I really had to hack my card bios.  Like I mention, if I connected the screen with my portable (also archLinux), it run fine, but my portable have a nVidia card, not an Intel one !

Have a nice day !
