[gentoo-user] Can't boot into X

[gentoo-user] Can't boot into X

[Colleen Beamer]

[-- Attachment #1: Type: text/plain, Size: 1657 bytes --]

First, I looked in the archives and didn't find anything relevant - could be
my stupidity, but I did try!

About 6 days ago, I updated my system and since then, I can't boot into X.
My nvidia driver loads okay and it looks like it is going to start X, but
then reverts to the command line.  I've been sick and haven't really been
able to follow this up.

Also note that I can't provide any output because I am, obviously, not on my
computer.  Details are as follows:

From my kdm log the last few lines are as follows:

(EE) Failed to load module "dri" (module does not exist, 0)
(EE) Failed to load module "dri2" (module does not exist, 0)
/usr/lib/kde4/libexec/kdm_greet:  error while loading shared libraries:
libpng12.so.0:  cannot open shared object file:  No such file or directory

I don't have a dri USE flag in my make.conf file
The dri line in my xorg.conf file exists, but it is commented
I do not build dri into my kernel

Yesterday, I decided to try another update to see if there was an ebuild
that might have corrected whatever the problem was

On attempting to upgrade gtk+, it fails and I get told to run:
emerge --info =x11-libs/gtk+-2.18.9

When I do that, there is a USE line which includes dri and I'm not sure
where that is being pulled from unless it is global because as stated
previously, I don't have a dri USE flag in my make.conf or an active line in
my xorg.conf file.

Regarding libpng - on my first upgrade 6 days ago, I removed libpng prior to
doing the update because the updated libpng file was being blocked by the
existing one.  I don't know if this makes a difference.

Any advice on how to fix this?

Regards,

Colleen

The dri messages are normal for nvidia.

Run revdep-rebuild to fix the png issue.

Fine :)

I have this too, when using ati-drivers. I think the nvidia-drivers also 
have their own dri, so this is okay.

This is the problem. /usr/lib/kde4/libexec/kdm_greet links to 
libpng12.so.0, which you removed. It needs to be rebuilt so it links 
against libpng14.so.0. A simple emerge -1 kde-base/kdm should solve this. 
Use ldd /usr/lib/kde4/libexec/kdm_greet to verify this, there should be no 
'not found' entries.

Better use revdep-rebuild, there might be many other things that are still 
linked to the old libpng. 

You could also try to emerge media-libs/libpng:1.2, this will install the 
old libpng in parallel. At least I do have both on my system, but my kdm 
inks to 1.4. If the revdep-rebuild list is very long, maybe you can get a 
working system faster this way.

emerge -1 `qlist -I -C x11-drivers`

is always a quick test?

Since this is a common problem, create a set with those packages in it 
and then just rebuild the set.  This is my set up:

/etc/portage/sets/xorg-drivers

Which contains the following packages:

root@smoker-new / # cat /etc/portage/sets/xorg-drivers
x11-drivers/nvidia-drivers
x11-drivers/xf86-input-evdev
x11-drivers/xf86-input-keyboard
x11-drivers/xf86-input-mouse
x11-drivers/xf86-video-nv
root@smoker-new / #

This way you don't have to remember the command to list them but just 
re-emerge the set.  Your packages may differ so don't copy mine exactly.

May not fix the current issue but may be handy in the future.

media-libs/libpng-1.4.2 is still ~amd64 and ~x86, so there shouldn't be a need 
to emerge it at this stage.  Alex's suggestion to emerge -1aDv kde-base/kdm 
will most likely fix your problem and you can run revdep-rebuild afterwards 
for good measure.

Thanks for the response.  However, this has opened another can of worms and
I'm bowing to the expertise of this list to help

I don't remember why I unmasked the unstable version of libpng.  However,
following your advice, I first attempted to reinstall kdm.  This had been an
update 6 days ago when all this started.  The emerge bombed.  Therefore, I
fixed my package.keywords file so, the unstable version of libpng would not
emerge and re-emerged libpng.  I can now boot into X.

The can of worms comes from doing revdep-rebuild.  However, the actual
revdep-rebuild bombs and I get told that there are no e-builds to satisfy
PyQt:0.

I admit that I have qt3support as a USE flag. Don't know if this is the
issue and if I should remove it.  Advice?

Okay, this should have fixed a lot of broken things. I guess your revdep-
rebuid list would be even longer without this library.

PyQt is in the kde-sunset overlay which contains all stuff needed for KDE 
3.5. Do you have such things installed? Or is PyQt accidentally in your 
/var/lib/portage/world file? emerge -pv --depclean PyQt should show you 
which stuff pulls it in.
If you think nothing needs it, remove it with emerge -Ca PyQt, and try 
revdep-rebuild again. Or add the kde-sunset overlay with layman.

I do not have it set explicitely, but for me this USE flag is also 
activated, probably because of the desktop profile. I do not have PyQt 
installed.

As it turns out, this wasn't necessary.  On running revdep-rebuild, a
lot of files were looking for libpangocairo.  Thinking that I'm so
smart, I tried to emerge this, but of course, there was no such
package.  A google search discovered that libpangocairo is provided by
pango-1.28.x.  I only had 1.26.x on my system.  1.28.x was masked, but
if fixed my package.keywords file, emerged pango-1.28.1 and that solved
all of my problems - I could even do the remaining updates on my system
which started with gtk+.

Not sure exactly what was going on here, but I'm back and running and
that's all I care about.  revdep-rebuild has been cleared.

Anyway, thanks for all the help.

Regards,

Colleen
