okay, this is quite possibly DRI-related. if you comment out the Load "glx",
Load "GLcore", and Load "dri" lines in xorg.conf, does everything work? failing
that, how about Load "extmod"?

That works around it. I assume this is just a symptom of all the other ATI DRI
madness elsewhere in bugzilla?

Let me know if there is anything else you'd like me to try.

nope, that's all fixed -- looks like a proper driver bug.

Is there still additional information needed (this bug is still NEEDINFO)

Nope, I just neglected to clear that flag. Although, I still need to verify this
with a recent install. I don't suppose you know which package version is
supposed to include this fix?

This is still broken in the Breezy RC.

Just like to confirm that this bug is still there in Breezy.

Any likelihood that this will be fixed in Dapper?

This is quite old so we'll have to get info so I'm flagging this as Needs Info. I would assume it got fixed so please give a shout if it is fixed or not in a Dapper milestone release if its possible for you to test it.

I still had no video without manual intervention when I tried flight 4. Copying over my old xorg.conf (with DRI disabled) "worked" (but I obviously can't do anything requiring GL).

I think I hit two bugs: One broke a bunch of different systems because X autoprobing wasn't working during setup. I believe that is now fixed.

The other is this one, which AFAIK is unfixed.

A recent upload of xorg mentioned that a ton of ATI driver fixes were imported from upstream, so I'll try my luck with a recently daily build as soon as I find the time to back up and reinstall.

I'll let you know if things have changed.

Still broken in flight 6.

Workaround: Comment out Load "dri" in the "Modules" section of xorg.conf.

An interesting line from xorg.log that seems to be related:
"(WW) RADEON(0): [dri] detected radeon kernel module version 1.19 but 1.23 or newer is required for full memory mapping."

Let me know if you'd like any more information attached.

Hi Adam,

Can you upload the full /var/log/xorg.0.log from a failed dapper boot as well? Thanks.

(as title)

Changing status to confirmed since it has been confirmed by at least one other person. Assigning to ubuntu-x-swat.

Thank you for reporting this issue.

I've read elsewhere that this is related to AGP. Another work-around is to add the line

Option "BusType" "PCI"

to the video card device section in xorg.conf. You don't have to comment out the gl related modules, but acceleration still doesn't seem to work - glxgears at about 2 fps.

Changed package to xserver-xorg-video-ati, as this only happens to users with ati driver.

If possible, it would be nice to check if you can still reproduce this problem with the current development of Ubuntu. 3D support was worked very hard on in the last few weeks, and the whole stack of relevant packages (libdrm, mesa, xorg-server and xserver-xorg-video-ati) have been updated.

Note that you won't need to reinstalll your machine. Our livecd attempts to boot and configure X.Org with the correct driver, and the best resolution possible.

You can download it from here -> http://cdimage.ubuntu.com/daily-live/current/

Finally, the *current* (20060823) image is broken (unrelated to X.Org), when/if you download it, please download the image from 20060824 onwards (when it becomes available)

Thanks in advance for the testing.

X works perfectly now (and supports DRI again!). However, the console is now garbled when switching to it from X (control-alt-f1, etc). (console is shifted over -- left half of the screen is black and the remaining text is "ghosted")

I had an smimilar problem! Just changed
driver "nv"
to
driver "nvidia"
and everything was OK (Live-CD->ctrl+alt+f1, edit xorg.conf, restart X)

Radeon Mobility 9000 works here fine as well, in Ubuntu 6.10.
