Xorg 7.4 + dri = frozen machine

M

mdg

I am running 7.2-Stable with Xorg 7.4 and things run fine as
long as I disable DRI and DRI2 in xorg.conf. I would like to
get dri working, if possible, to see if it gives me better
performance.

If I enable DRI and DRI2 in xorg.conf, then my machine freezes
on starting with startx and all I get is a blank screen and I
need to use the power button to restart the machine. I have
HAL enabled and I have tried all kinds of variations on my
xorg.conf as recommended (setting AddEmptyInput, AutoAddDevices
etc) with the same result - a frozen machine.

When the system freezes I do not even get an Xorg.0.log file.
I can force one by using X -probeonly and I have included that
below. One thing that I notice is that DMA never gets enabled.

Any suggestions? Attached are my Xorg.0.log (using X -probleonly), xorg.conf, and the output of dmesg.

i can assure you have an intel graphics card... look around a little and you'll see, this is an xorg + intel drivers issue, i tryed everything you can found on google in linux + freebsd forums, irc chatrooms, etc... the only way i can think of it's to downgrade to the latest "stable" xorg release 7.3 (Released: 2007-09-06 as listed here http://www.x.org/wiki/Releases?action=show&redirect=XorgReleases) so let see how this thread grows :)
 
FYI, no cards support DRI2 on FreeBSD, though I doubt this is the source of the lock up. Does it work if you disable DRI2 but leave DRI enabled?

add this (Option "AllowEmptyInput" "off") on your xorg.conf just like this.
Code: 
Section "ServerLayout"
	Identifier     "X.org Configured"
	Screen         "Screen0" 0 0
	InputDevice    "Mouse0" "CorePointer"
	InputDevice    "Keyboard0" "CoreKeyboard"
        Option         "AllowEmptyInput" "off"
I modify your xorg.conf have a look and try it.

Is this a complete freeze of the system or can you remotely access the box after X locks up on you?

ericturgeon: Tried your conf file. Still have the same problem. Thanks

adamk: It is a complete freeze. Cannot remotely access the box.

I tried loading the mach64 kernel module.
Code: 
kldload mach64
and this enables dma, but still no luck.
 
Do you get any errors (at the terminal or in dmesg) if you manually load that kernel module?

I think you might need to post on the freebsd-x11 mailing list, though I'm not sure if the current DRI maintainer has any mach64 hardware to test on.

Re: Xorg 7.4 + dri = frozen maching

No errors on manual install of mach64 module either at the
command line nor in dmesg. Here are the last few lines of
dmesg
Code: 
GEOM_LABEL: Label ufsid/4a1c15c136d8e46a removed.
aue0: link state changed to UP
drm0: <3D Rage Pro AGP 1X/2X> on vgapci0

[Solved] Xorg 7.4 + dri = frozen machine

I finally got DRI working on this old 3D Rage Pro AGP 1X/2X
in an old HP Pavilion 4455 with a Pentium 2.

Somehow, building a custom kernel did the trick. I commented out
over 150 lines of stuff that I neither need nor can use and that
seemed to make the difference. The problem is that I do not know
what I eliminated that made the difference. Could it be that
I removed the wireless HAL driver?

I also needed to load the mach64 kernel module either by hand
or in loader.conf, but that did not work until I rebuilt the
kernel.

BTW: I needed to comment out AllowEmptyInput and
AutoAddDevices as below
Code: 
Section "ServerFlags"
        Option         "DontZap" "Off"
#       Option         "AllowEmptyInput" "Off"
#       Option         "AutoAddDevices" "False"
EndSection
in xorg.conf to let HAL do its job. Otherwise my keyboard and moused did not work properly.

One problem that remains is that Ctrl-Alt-Bksp does not kill
the X server even though I have turned "DontZap" off as you
can see above. Any suggestions? I still can kill the server
using the fluxbox command.

Thanks for the help from this forum.
 
Try running this command and then killing X with control-alt-backspace:

setxkbmap -option terminate:ctrl_alt_bksp
 
adamk:
That worked! Thanks.
My WM is fluxbox. Any advice on making that keymap the
default?
