Xorg & i810 graphics / loader.conf / kldstat

[OgreNaut]

Hi, I'm somewhat of a FreeBSD noob, but not a *nix noob.

I'm having problems getting Xorg to work properly with my hardware. I'm running 7.0 on an old Compaq Deskpro EN 733PIII. It has i815 Intel graphics, which is supported by the i810 driver packaged with 7.0.

I've been reading copious amounts of documentation and experimenting to get this going. With both Gnome and KDE, I just get a messed up screen; I can see bits of each desktop environment and the mouse works, but they're unusable. I have my monitor settings perfect, including the arcane Modeline settings.

Following the FreeBSD X11 config guide (http://www.freebsd.org/doc/en/books/.../x-config.html), I have set agp_load="YES" in /boot/loader.conf, but when I do a kldstat, the agp.ko module isn't listed. This agp.ko module is essential to getting the i810 driver to work. What gives? Why isn't agp.ko loaded, even though I've specified it in loader.conf???

The agp module is part of the GENERIC kernel, you don't need to load it.
kldstat doesn't show the modules built in the kernel, to show the modules in the kernel, use the -v flag.

I'm having problems getting Xorg to work properly with my hardware.

What problems exactly?

You should use intel driver instead of obsolete i810. In my experience one of the common
reason for failure of X server with intel driver that it supports only DefaultDepts up to
24 even though your hardware might support something higher (32).
Force X server to use DefaultDepth 24 by editing xorg.conf file. Also try to increase
vertical and horizontal refreshing rates.
Finally put something reasonable for Modes "1024x768" comes to mind.

And did I say that you sould read your xorg.log file:--)

Indeed, you're right about the kldstat flag! There's my i810 driver!

$ kldstat -v | grep agp
                408 hostb/agp_ali
                409 hostb/agp_amd

Here's some interesting stuff from my Xorg.0.log. Important?

...

drmOpenDevice: open result is -1, (No such file or directory)

[drm] failed to load kernel module "i810"
(EE) [drm] drmOpen failed.
(EE) I810(0): [dri] DRIScreenInit failed.  Disabling DRI.
...

Any ideas??? I've been working at this for a few days.

If you're getting a "mixed up desktop" with multiple images showing, then your resolution and refresh rate are set incorrectly, which points to either an invalid ModeLine setting, or an incorrect resolution setting.

What happens if you comment the VertRefresh, HorizSync, and ModeLine lines?

[OgreNaut]

What happens if you comment the VertRefresh, HorizSync, and ModeLine lines?

This is what I get, with no inkling of GUI loading:

Fatal server error:
AddScreen/ScreenInit failed for driver 0

Isn't THIS message a major indicator of what's going on?:
(From my previously posted Xorg.0.log)

[drm] failed to load kernel module "i810"

Kind of a strange message. Hmmm...just looked in /boot/kernel for i810 module. Found i915.ko, but not i810.ko. Normal, or weird? Perhaps i915.ko IS the module file that contains the i810 driver, as well as a few others?

Forgot to mention that this has been checked and double checked. The detected values by "Xorg -configure" match the manufacturer's specs:
HorizSync: 24-80
VertRefresh: 50-75

I checked it against the monitor's manual.

Have you tried the "intel" driver yet? It really is recommended over the unsupported and unmaintained i810 driver.

Also, the i810 kernel module Xorg is trying to load is for 3D functionality. It really should not be impacting your normal gnome or KDE desktop.

DRI/DRM is not enabled (causing various errors on screen)

Add this to your xorg.conf

Section "DRI"
	     Mode 0666
EndSection

[adamk]

The reason that DRI/DRM is not enabled is due to this:

[drm] failed to load kernel module "i810"

And I really doubt it has anything to do with his normal 2D desktop corruption, though I have been wrong in the past.

Adam

[richardpl]

You missed fact that following lines are displayed before error you mentioned.

drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is -1, (No such file or directory)
drmOpenDevice: open result is -1, (No such file or directory)
drmOpenDevice: Open failed
drmOpenDevice: node name is /dev/dri/card0
drmOpenDevice: open result is -1, (No such file or directory)
drmOpenDevice: open result is -1, (No such file or directory)
drmOpenDevice: Open failed

[richardpl]

To OP:

Make sure that drm.ko & i915.ko are displayed in kldstat output.

[adamk]

That's the result of the i810 kernel module not being loaded and being unloadable.

[richardpl]

There is no i810 kernel module.

[adamk]

That's my point :-) Which is one of the reasons I suggest he move to the "intel" driver... Well, other than the fact that the intel driver is newer and actually maintained.

[richardpl]

There is very little difference from user point of view when enabling DRI with intel Xorg driver or i810 Xorg driver.

In both cases, with i810 or intel xf86-video driver same kernel module: i915.ko is used (plus drm.ko).

Also user do not need to replace i810 with intel in xorg.conf file, user just need to deinstall xf86-video-i810 and install xf86-video-intel.

Anyway, DRI works with both Xorg drivers(on graphics cards that such drivers suppport).

AFAIK intel is maintained but have much more bugs than obsolete i810 driver (now also marked as broken port) for old cards.

In other words switching Xorg drivers will not improve OP situation in any way (as side efect it may make it even worse).

Already fixed this. No dice.

Neither of these are present in output from kldstat OR "kldstat-v". I grep'd 'em to make sure.

Now what? Manually load those in loader.conf?

Where might I find this mythical intel driver thou speakest of? From what I can tell, there is no maintained "intel" driver for FreeBSD anymore. The FreeBSD ports archive states that it was last released in 2007 and has now been deemed deprecated (http://www.freebsdsoftware.org/x11-d...deo-intel.html). Of course, I could always try building from source using the code from the good folks at http://intellinuxgraphics.org, but that seems like it should be unnecessary if the FreeBSD folks have decided to omit it from 7.0.
