Bug Description

Binary package hint: xorg

I recently upgraded to natty narwhal and lost X. I have been using the OSS radeon driver in the meantime, but prior to the upgrade, I was happily using FGLRX via the ATI Catalyst Driver. After the upgrade, X wouldn't launch and there is a seg fault in the Xorg log file (attached). Any extra information can be provided as the crash is easily reproducable (for me).

Why don't you give me the output of the following (typed into the terminal):

LIBGL_DEBUG=verbose glxinfo | grep render

NOTE: The first time you try the above command it may require you to install "glxinfo". YOu can do this by:

sudo apt-get install mesa-utils

Also, the output of ...

/usr/lib/nux/unity_support_test -p

Thanks.

I am not sure if I made it clear, but the X server does not launch, at all... When I have fglrx installed and I have X configured to use the fglrx driver, I can only get a text console. If I type those commands into the console, I only get "Cannot open display."

With X configured to use the radeon driver, and fglrx "purged" (using `dpkg --purge`), I can get into X. So, using the radeon driver, the output of those commands is as follows -

Please try this after installing fglrx:

* Uninstall fglrx if it's still installed
* rm -rf /etc/ati
* Install fglrx again
* Reboot

Does X start successfully after this?

I don't have an "/etc/ati" folder... In fact, when I produced that stack trace above, I had uninstalled fglrx via:

sudo dpkg --purge fglrx fglrx-dev fglrx-amdcccle

and then I reinstalled by downloading the debs directly from the ubuntu repository and installing them (just in case a prior attempt at installing debs generated from the ATI-provided catalyst download [ati-driver-installer-11-4-x86.x86_64.run] had confused my apt database).

Then following the previously-linked directions for launching X in gdb.

I can go through it again, but the fact that this crash happens consistently is the reason I filed the bug.

I am not sure if I should close this bug, but I downloaded and installed the catalyst driver from here -
http://support.amd.com/us/gpudownload/linux/Pages/radeon_linux.aspx?type=2.4.1&product=2.4.1.3.42&lang=English

The version number on that page was 11.5, after having it build packages for natty, the following files were created -

fglrx_8.850-0ubuntu1_amd64.deb
fglrx-amdcccle_8.850-0ubuntu1_amd64.deb
fglrx-dev_8.850-0ubuntu1_amd64.deb
fglrx-installer_8.850-0ubuntu1_amd64.changes

After installing them, I am now able to launch X with 3d acceleration sufficient for running unity!

The only reason that I am not closing this issue is that I am not sure if maintainers are planning on moving to this new version of catalyst as well. If the bug should be closed, let me know or just close it. Thanks again guys!

Hey wesw,

You filed this bug report against natty, but I see it's still open and
doesn't appear to have much activity recently. So, now that oneiric
is released and stable, this may be a good point for you to upgrade
and re-test if this issue is still present there.

If it's solved in the new release and you think it's worth backporting
the fix, please indicate that. Or if having the fix in the new release
is good enough, feel free to close out the bug (or let us know and we'll
close it.)

If it's not solved, leave the bug report open. I can't promise we'll
get to it (we get way more bugs filed than we can usually get to), but
your testing and feedback can help out if and when we do.

Bryce, I haven't upgraded (yet) past natty, but I don't think the fix is worth backporting... As mentioned in a prior comment, building debs from the catalyst driver downloaded directly from ATI fixed the problem months ago and I haven't had to worry since. I am not sure what status that leaves this issue... whether unconfirmed, fix released, or simply letting it stay at incomplete until it expires on its own. I'd rather leave it up to you guys to mark it appropriately so that it is out of your hair. If/when I upgrade, if I have further problems I can always reopen or create a new issue. Thanks again for the work you guys do!
