[gentoo-user] xorg-x11 screwup

[gentoo-user] xorg-x11 screwup

[Matthew R. Lee]

I upgraded my xorg-x11  the other day.  I followed the upgrade how-to, and 
everything seemed to go fine.  However when I rebooted it was screwed up.  
The xorg.conf was a mess.  I tried fixing it from memory but I couldn't sort 
it, and I'd forgoten to make a back up MY FAULT.  Anyway I downgraded to 
xorg-x11-6.8.2-r8 and got x back and sorted out the problem with the 
xorg.conf and made a backup.  I then attempted another go at upgrading and 
here's the problem.  I follow the guide again and after 'emerge xorg-x11' it 
says there is nothing to download, compiles nothing, cleans up and claims it 
is done.  I wasn't convinced, however I tried rebooting.  No X, so I logged 
in and issued 'startx', nothing so I checked '/usr/bin/startx', it's not 
there, clearly it hadn't installed x  So back to xorg-x11-6.8.2.-r8.  I've 
tried another emerge --sync to see if that would fix the problem but no joy.  
So the question is, how do I force portage to down load and recompile the 
packages from scratch?

This is a really weird issue that's been coming up, where the packages
are "installed" but files are missing. What filesystem(s) are you using?

You could try `emerge -ep xorg-x11`.

When user upgrades to modular X.org there is a block that requires him to 
remove xorg-x11-6.8*. Then the user upgrades, reboots and finds out there is 
something wrong. So he downgrades. But when downgrading there is no block 
requiring him to remove modular X first. So he merges xorg-x11-6.8 which 
overwrites a *LOT* of modular X files like e.g. startx and only unmerges 
xorg-x11-7.0 which is a very small package. Now the user decides to upgrade 
again so he unmerges xorg-x11-6.8 again and it removes all the files but 
portage still thinks modular X is installed except of xorg-x11-7*. So when he 
emerges xorg-x11-7* that package is the only one which is remerged...

That's a definite possibility. But I don't _think_ everyone encountering
this problem has hit it, although I could be wrong.

nichoj experienced a similar thing with java-config-1.2 vs. 
java-config-wrapper. It wasn't many but there were a few who did this. 
Anyway, in this case the OP specifically stated that he did just this.

yes I hit it too - back before it hit stable.  It seemed that going xorg
modular is a one way trip as you cant remove modular xorg easily unless
you keep an independent record of every package installed.  I was pissed
because modular didnt work and I couldnt uninstall it!  Eventually
updates caught up with and fixed the problem, but in the meantime I had
an unusable system.  I realised the problem when I coulnt even downgrade
from 7.1 to 7.0 - this loss of control is a major pita with modular X.

Maybe what is needed is an enhancement to portage to allow the removal
of a meta-package to (optionally) also remove the 'real' packages
which it caused to be installed.

Heard of emerge --depclean? Use it with care, though.

ummmm think about this.

new system, no gui installed.

I install kde-meta, which installs xorg-x11 as a dependency.

I decide I want gnome, I install gnome which doesn't install xorg,
because it is already installed.

I decide I do not want kde because i prefer gnome. I unsinstall
kde-meta. Under your scheme it would also uninstall xorg-x11. But that
is not what you want!

Hmm, it can be done with "garbage collector principe". Each
package will have counter which increases when some package which depend on
it is installed. Decreased, when the package is uninstalled. If counter is
zero, "dependency" package can be uninstalled along with package specified
for uninstalling.

No, that still doesn't work. When the user unmerges kde-meta, with your
proposal it will unmerge X11. The next step is that the user emerges
gnome which first emerges X11 back again. This isn't so bad with a
binary distro if the packages are on a CD, but on gentoo it's murder.

The only sane thing to do is to emerge dependencies when required and
unmerge only thinks specifically asked for to be unmerged. You can't
even reliably prompt the user with a dialog that says "The following
dependencies of the package about to be unmerged are needed by no other
package. Shall they be unmerged?" because of *deep* dependencies.
Reverse constructing a multi-node tree and applying logic to it is no
joke, hence the wise decision to have portage ignore this amazingly
efficient bug-injecting process.

Yes, its not so easy, i see now. ;-) Like Bo Andresen wrote --depclean is the
best way.

Except i this example you are likely to install GNOME before removing
KDE, otherwise you'd be left with no desktop.

If you have the disk space to spare, set FEATURES="buildpkg". Then
reinstalling a package is as quick as with a binary distro.

The further complication there is that in this hypothetical situation
you are also likely to be changing some USE flags, and the prebuilt
buildpkg packages may need in fact to be built again against a new set
of libraries.

All of which is why I am glad I don't have to maintain portage and its
associated tools :)

Changed USE flags won't normally stop a program running. Re-emerging the
previous version gets you working again in no time at all. you can then
recompile if you wish, while still being able to use the computer.

I guess what I would do in your situation would be to just nuke everything in 
the x11 categories:

# grep x11 /var/lib/portage/world
# cd /var/db/pkg && emerge -Cva x11*/*

The first gets a list of the x11 packages that you had in your world file. The 
second removes all of it. Then I would emerge modular X.org again and make 
sure not to overwrite it by emerging monolithic X.org.

That's gonna remove lots of non-xorg stuff, and not catch all xorg stuff.

You can grab a list of all modular X packages at
http://www.gentoo.org/proj/en/desktop/x/x11/modular-x-packages.txt and
run this:

emerge -1 $(<modular-x-packages.txt)

I'm running ext3 file system
I've had a look at the above but it want's me to unmask a whole bunch of 
packages. I'd prefer to stick to the stable stuff.  I've only the one laptop 
and a lot of work on at the moment.  I can't afford to be out of action for 
too long

Try removing all the media-fonts and x11-apps stuff from there.

You can try this. It only emerges packages that are already installed:

# while read pkg; do equery list "$pkg" | grep -q "$pkg" && emerge -1 "$pkg";
	done < modular-x-packages.txt

In the end I did an emerge -e xorg-x11.  It was a huge 194 package.  It ran 
into some problems, a bunch of xlibs wouldn't install which cause futher 
problems cascading down the list.  (32 packages failed to emerge, I can 
provide a list if you need it)  Anyway I went past them with 
emerge --resume --skipfirst.  After the emerge -e xorg-x11 had finished I 
went back and emerged the failed packages individually.  Everything emerged.  
Does that mean portage was trying to emerge the packages in the wrong order?
I've rebooted and my new x environment appears to be working fine.
Thanks for the help
Moral of the story: make back ups of critical conf files you've changed 
yourself before embarking on major upgrades like this :-)
