Installing then uninstalling FGLRX makes Oneiric's Unity unbootable

Can you please try removing fglrx again, and before you reboot do:
sudo dpkg-reconfigure libgl1-mesa-glx

I doubt this is a compiz bug , it probably something with fglrx's posrm script

I will as soon as I can, I am currently away from a stable connection (in case something goes wrong, I wouldn't be able to fix it)

That command did NOT work. Same broken environment upon restarting.

OK. What about
sudo update-alternatives --config x86_64-linux-gnu_gl_conf
and you choose /usr/lib/x86_64-linux-gnu/mesa/ld.so.conf, and reboot?

Even better, just post the result of
cat /etc/alternatives/x86_64-linux-gnu_gl_conf after you remove fglrx

Just tried it myself on another install; it is broken; this is after removing fglrx:

Reinstall libgl1-mesa-glx solves the issue; so fglrx should have a update-alternatives trigger...

This is not compiz bug, it's fglrx's

šumski: did you remove fglrx manually (e.g. with sudo apt-get remove fglrx) or through Jockey?

Alberto, i used jockey for both installing and uninstalling. Will try both with apt-get

I too have this bug. I tried all of the previous fixes and none worked. I am on 11.10 x64 beta 2, and I can say this problem has occurred on both of my computers and I have tried each with jockey and with apt-get, both achieving the same result.

My laptop is running an mobility radeon hd4250 and my PC is running a radeon hd 6950

Edit on my previous comment:

I ran this command 1 last time and received this result:

After reboot it did in fact fix my desktop.

So for some reason, after removing fglrx in the onieric builds, mesa-glx is not getting reinstalled

same for me but when i run the re-install comand for libgl1-mesa-glx : (sorry, it is in french, but the last line, the error, is in english)

I had the same issue, I got around it by installing synaptic and telling it to reinstall both libgl1-mesa-glx AND libgl1-mesa-glx:i386. Hope that helps you.

Also, is anyone actually working on this bug?

please try to reproduce the issue and attach your /var/log/jockey.log or I won't be able to see what's going on (and fix it)

Here you go !

On 64-bit Oneiric

sudo apt-get install --reinstall libgl1-mesa-glx

did help after removing fglrx , now I'm able to run gnome-shell again without top panel being corrupted.

whatever is happening here, it should definitely be fixed by SRU.

Agreed, for non-techie users it’s going to break their systems in a way they can’t fix (neither Unity nor Unity 2D work with the broken libGL).

I did the procedures suggested by @jiri-gronroos and @shroudedcloud, with these reuslts:

    E: Internal Error, No file name for libgl1-mesa-glx

Did you do what I said in comment #16? (I.E. also get libgl1-mesa-glx:i386?)

Aha. In trying to use --reinstall, I ended up hitting another bug, #859188. On that bug, commenter Sal Mazzola (@salmaz) suggests using this alternative method to work around it:

    apt-get download libgl1-mesa-glx libgl1-mesa-dri
    dpkg --install libgl1-mesa-*.deb

I now have working GLX again!

Good point, Jonathan. For copy/paste convenience for folks:

    apt-get download libgl1-mesa-glx libgl1-mesa-dri:i386 libgl1-mesa-glx:i386
    dpkg --install libgl*deb

I've just uploaded the fix in precise and in oneiric-proposed

Hello Jonathan, or anyone else affected,

Accepted fglrx-installer-updates into oneiric-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

Confirming the fix in oneiric with fglrx 8.881-0ubuntu4.1.

Thanks a lot !

But "link group x86_64-linux-gnu_gl_conf is broken" itself is NOT fglrx problem as the same happens even without fglrx installed! Inability to circumvent it or sometimes uninstall correctly may be, of course. I don't have "unbootable" problem, but GL still does NOT work normally on Oneiric, with versions - fglrx, fglrx-updates and downloaded Catalyst (the same which DID work perfectly on Lucid!) - differing in specific failures.

It's about mesa GL packages for Oneiric:
libgl1-mesa-dri libgl1-mesa-glx libglapi-mesa libglu1-mesa
In Synaptic they all are flagged as installed, but "installed files" lists are unavailable because packages are not installed, and an attempt to reinstall any of them causes this very error.

P.S.: another error on reinstall has libxrender1 (dependency of fglrx). "E: Internal Error, No file name for libxrender1"

TBeholder: the underlying problem is tracked as the Bug #859188, you might want to track it.

Since I upgraded it yesterday, it has become impossible to wake up my monitor from its energy-saving state. Whenever it has kicked in, only a hard reboot makes the monitor come back. No action on mouse or keyboard; the monitor remains pitch black.
I do NOT say it has to make with this package, but I never had this before and it totally coincides with this upgrade.
Details are available under bug 886496.
Contact me for a solution, or further details, please.

@udippel: I don't think my changes could ever caused what you described in the bug report. You can try removing fglrx and see if you can still reproduce the problem without it.

Can anyone please just tell me how to fix / reset this so I can install libGL again!???
