HOW TO: Configuring Xorg for use with Intel i810 and higher video cards

[lgiraud]

I try all the tricks given here with bad results... So I succed by my own :
I got a Knoppix-debian version that works with my I810 ( ) video card. So I edited the XF86Config file and just copy in the right section the "modelines" and other VideoRam, HorizSync and VertRefresh.
This is a little bit ugly but it works.

If its help, this is a part of my now working xorg.conf:

This didn't work for you?

I've seen a lot of people having issues with integrated Intel video chipsets. I though I'd share my success story (well, mostly success. There is one minor problem addressed at the bottom of this how-to). I successfully ran Xorg on an integrated i915 chipset, but I believe this will work for any i810 or higher video chipset since I'm using the i810 driver.

In my case, the specific problem I was dealing with is that the Hoary installer gave me the vesa driver, which is servicable, but not great. After running dpkg-reconfigure xserver-xorg and manually selecting the i810 driver, my LCD monitor would fail to accept the requested video mode unless I commented out the horiz and vert refresh lines in my xorg monitor config, then it would force me to use 640x480. This is apparently because a faulty video bios that doesn't report valid video modes. Thus, I needed to use a program called 855resolution to force a better video mode. This how-to walks you through the process of installing and configuring 855resolution, then changing your xorg.conf file to start with the i810 driver.

Let's go...

- run 'wget http://ftp.psn.ru/debian/pool/main/8/855resolution/855resolution_0.3-4_i386.deb'
- run 'dpkg -i 855resolution_0.3-4_i386.deb'
- run 'sudo gedit /etc/default/855resolution'
- add config from modes list

Mode 30 : 640x480, 8 bits/pixel
Mode 32 : 800x600, 8 bits/pixel
Mode 34 : 1024x768, 8 bits/pixel
Mode 38 : 1280x1024, 8 bits/pixel
Mode 3a : 1600x1200, 8 bits/pixel
Mode 3c : 1400x1050, 8 bits/pixel
Mode 41 : 640x480, 16 bits/pixel
Mode 43 : 800x600, 16 bits/pixel
Mode 45 : 1024x768, 16 bits/pixel
Mode 49 : 1280x1024, 16 bits/pixel
Mode 4b : 1600x1200, 16 bits/pixel
Mode 4d : 1400x1050, 16 bits/pixel
Mode 50 : 640x480, 32 bits/pixel
Mode 52 : 800x600, 32 bits/pixel
Mode 54 : 1024x768, 32 bits/pixel
Mode 58 : 1280x1024, 32 bits/pixel
Mode 5a : 1600x1200, 32 bits/pixel
Mode 5c : 1400x1050, 32 bits/pixel

eg. (you need 3 lines in the file)

MODE=58
XRESO=1280
YRESO=1024

(look in /usr/share/doc/855resolution/README.Debian for more configuration information if you want)

- run 'sudo /etc/init.d/855resolution start' (should provide feedback that the patch is complete)
- run 'sudo gedit /etc/X11/xorg.conf'
- In gedit, change your video driver to i810 (Driver "i810") in your device section. It is probably set to vesa by default.
- Restart X by pressing ctrl-alt-backspace or rebooting your computer.
- If X won't start after doing this you can go into command prompt mode from the Grub menu (recovery mode) and edit /etc/X11/xorg.conf to change your driver back to what it was (probably vesa)

- Note: on my system there is a problem where X initially starts in an invalid mode and my LCD won't display it. I switch to another terminal (ctrl-alt-F1) and then switch back to X (alt-F7) and then it works. I believe this is a refresh rate problem. I will update this how-to with a solution when I find it.

Got this to work. Also check out this thread regarding the fix to 640X480 problem: http://www.ubuntuforums.org/showthread.php?t=55614

HI,
I just wanted to post my xorg.conf as a reference, this is how I got mine to work...

http://www.majikstreet.org/xorg.conf

[TestDummy!]

I helped somebody with an i810 chipset.

I tried to follow this but in the end, this soulution did it..

All I did was add in the Hoirzontal Sync, Vertical Refresh and the Video RAM into xorg.conf, like so

Section "Device"
Identifier "Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device"
Driver "i810"
BusID "PCI:0:2:0"
VideoRam 65536
EndSection

Section "Monitor"
Identifier "SyncMaster"
Option "DPMS"
HorizSync 30-70
VertRefresh 50-160
EndSection

(Generic Disclaimer: Settings used for example, yours will vary depending on what monitor you have and what you have your BIOS set to allocate system RAM for video. Not responsible for blowing up your monitor or something )

From what I gather on here, the i810 chipsets sometimes get a bad count of memory from the BIOS and get X to think there is only 1MB to use for video, or something.

[Pancetilla]

Hi everybody, new to the forums, been using Ubuntu since July or so and now have bought a laptop:

I had the already known problem with the i810 but I could not work it out with the monitor frequency workaround. So I inserted the new Ubuntu 5.10 live preview, copied i810_drv.o from /etc/X11R6/.... to Ubuntu 5.04 and now it works alright, without changing anything in xorg.conf. The i810_drv.o file from 5.04 must be broken or something.

You can also get working i810_drv.o in the web, I think.

Bye and hope it helps.

So is direct rendering now enabled? What does glxinfo tell about direct rendering?

[tregetour]

I managed to get it to give me 1280x1024.

But: It's drawing everything twice in weird places. The refresh rate according to the screen resolution dialouge is 75 -- acording to my moniter it's 60. Could this be the problem? And if so ... how do I fix it? Thank you!

When I change the driver in xorg.conf to 'vesa' everything works peachy and the moniter says 75.

[the moniter is a BenQ FP731 -- the computer is an HP pavillion a600y]

thank you in advance.

I have very low fps on my acer notebook Intel 855GM
About 250 fps, after installation of DRI drivers.
There is no direct rendering how to switch it on?

I have similar problem 855gm and installed DRI following instruction (for intel i915) HOWTO: Enable DRI (3D support) on SAVAGE cards.
Fps is about 300, and lsgrep is showing:

lsmod | grep drm
drm 74168 2 i915
agpgart 34792 3 drm,intel_agp

but: glxinfo is showing no 3D rendering
$ glxinfo |grep rendering
libGL warning: 3D driver returned no fbconfigs.
libGL error: InitDriver failed
libGL error: reverting to (slow) indirect rendering
direct rendering: No

Any idea how to fix it?
