X hangs at startup (segfault in fglrx?) after Natty beta upgrade

[Jon Bailey]

Just did Natty beta upgrade, rebooted. System hung during X startup. Had
to use Alt+SysRq+R to get keyboard control back and switch to another
virtual console. Xorg.0.log mentioned that fglrx had segfaulted.

Worked around problem by purging all 'fglrx' packages, then using updatedb/locate to find all files on the filesystem containing the string "fglrx", checking to see which of them were actually owned by packages with:

for filename in $(locate fglrx); do dpkg-query -S $filename; done

and renaming out every file that wasn't part of a package (the only two that were were:
app-install-data: /usr/share/app-install/desktop/fglrx-driver.desktop
x11-common: /usr/share/apport/package-hooks/source_fglrx-installer.py
)

With all of those renamed out, X started OK (non-accelerated, using the 'radeon' driver)

I've had the same issue on my Upgrade from Maverick to Natty. I didn't use fglrx on Maverick, but had it installed once. Mainly removing /usr/lib/fglrx and /usr/lib32/fglrx manually solved the problem. I guess those where some leftovers from an incomplete Maverick fglrx uninstall.

[Christian Roessner (christian-roessner-net)]

I can confirm this bug, too. But I would need the fglrx driver working, because the radeon-HDMI-sound output does not work. It did in Maverick.

same problem here, after upgrade from 10.10 X doesent start, fglrx driver crashed:

[Michael B (a-launchpad-bretterklieber-com)]

I had to completely remove the fglrx, removed xorg.conf, rebootet with opensource radeon driver, and than I did a fresh install with jockey, this solved the problem.

It looks like a problem with the upgrade procedure, the fglrx kernel module was not build

Hey hobart,

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.

[bugbot (bugbot)]

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.
