Hi guys, I need some help with this:
today, I updated gentoo, the following packages got emerged:

sys-kernel/linux-headers-3.18
sys-libs/glibc-2.20-r1
dev-libs/libffi-3.2.1
sys-devel/binutils-config-4-r1

Most of which are just dependencies, but after this update, I noticed these emerge errors:

This package will overwrite one or more files that may belong to other
packages (see list below). You can use a command such as `portageq

NOT file a bug report. A bug report is only useful if it identifies at

If a collision occurs and you can not explain where the file came from
then you should simply ignore the collision since there is not enough

a bug report at http://bugs.gentoo.org unless you report exactly which
two packages install the same file(s). See

After restarting my system, glx didn't work anymore:

I downgraded the 5 ebuilds which caused the errors before by masking each of them:

but no success, glx remains dead...

does anyone know how to fix this?

I checked some settings and found something really really weird:

Code: Select all

# eselect opengl list
Available OpenGL implementations:
  [1]   nvidia
  [2]   xorg-x11 *

The update must have changed that, but I have no idea how...
changing it back, fixed glx, so the module can be loaded again, but I'm not sure if I should update the masked packages again. I might try though to see if there's a bug involved

Utsuho Reiuji · Post by **Utsuho Reiuji** » Mon Jan 05, 2015 10:00 pm

ok, I could confirm my suspicion. unmasking the 5 packages in my 1st post and running your world update will break glx.

I'll create a bugreport..

Naib · Post by **Naib** » Mon Jan 05, 2015 10:57 pm

There already is a bug report. The newer eselect-opengl & xorg have caused a few issues with proprietary drivers and their libglx implementations

It hit me too. Downgrading did not resolve it here.
I´m kind of stuck with it.
Looks like a screw-up in eselect-opengl to me.
Any news on when the bug is fixed?

In my case, everything is Ok appart 1 aplication:
after an update - primusrun error - only for 1 aplication
https://forums.gentoo.org/viewtopic-t-1 ... ight-.html

I did try everything, downgrade everything connected to X, video drivers, to early December version - did not help.

Code: Select all

or

   Current serial number in output stream:  24

Looks like something during an update was over-writen, and reemerging standard packages did not help, but what was over-writen? Maybe it will be useful be to check packages, who gave files with colisions?
Eg. - how to check which package gave khrplatform.h?

Shortened output, basically no GLX,

lshw, lspci http://pastebin.com/PbKNAN4D

No idea how to fix that issue. Legacy Driver is maybe different to current implentation if you have a newer card.

My workaround is emerge-webrysnc and use a date 30-12-2014 or earlier

as the bug suggests:

get rid of your old xorg.xonf. I suggest you rename and keep the old xorg.conf

create this file, as suggested in the bug-report

Code: Select all

localhost roman # cat /etc/X11/xorg.conf.d/nvidia.conf

localhost roman #

restart your x-server and check if it works. It works for myself.

I highly recommend an eselect news about this.

I'm really tearing my hair out with this issue. I've been stuck with a working Gentoo KDE Session but with no OpenGL acceleration for over a month now...
I'm using Nvidia 340.65. I've tried everything I can think of (downgrading xorg-server and eselect-opengl, using different kernels, etc., etc.)

I've not seen / received any (eselect) news items about this bug... How did you hear about it?

Removing my xorg.conf file and just running with:

Try this... this should work.

Code: Select all

#cd /usr/lib64/xorg/modules/extensions/
#ln -snf /usr/lib/opengl/nvidia/extensions/libglx.so libglx.so
systemctl restart gdm

Thank you very much Cr0t !
I had the same problem and your advice worked for me. (only that I 'm on x86 so I had to change /lib64 to /lib )

This issue is solved for me.

I think I'll have to file a separate bug report about the problem I'm experiencing... I just can't seem to work around it

Thanks

In effect, you're saying that this link must be removed manually when eselect opengl is fixed?

Thank you, I understand. I actually found some stale links in that folder from 2009 which I removed before I created the new one!

One reason I've recounted all this in this thread is so I can go back when the next revisions come out, hopefully with bug fixes, and sort it out easily; and also so that others who have read these threads have all the information.

What I don't understannd is why people are prefering todo the ln method (and potentially setup a dormant failure when the eselect-opengl fix is realised) rather than doing what is recommended in the bugreport

ie

1) do not have an /etc/X11/xorg.conf
2) use /etc/X11/xorg.conf.d/* files
3) MAKE SURE it is only the 10opengl.conf file that has any file declarations

ct85711 · Post by **ct85711** » Tue Jan 20, 2015 10:40 pm

I believe partly why, is because of the 10opengl.conf file is causing some of the issues. When I first encountered this, I had no xorg.conf file and only a single file in xorg.conf.d only specifying to load the nvidia driver (no file declarations anywhere). Having xorg look for 32bit drivers first on a 64bit system compounded the issue.

When I looked into the issue myself, I found out the 10opengl.conf file wasn't being remade properly in the first place; which was causing all the issues. Luckily I knew how the files are loaded up, and saw it was trying to load a invalid file (that the old eselect left behind as a dead link). As I mentioned before in one of these various posts for this issue, I removed the invalid link, and corrected 10opengl.conf to point to the correct location (which should be the correct thing done).

The problem also lies in that people just what it to work, they don't want to fight with some "new" way, specially when this new way is NOT compatible for anyone with a old xorg.conf file that works for everything they needed for a while. I would have been in the same boat, except I'm running ~amd64 and for a while didn't have ANY xorg.conf(.d/*) till I switched drivers.

joe4379 · Post by **joe4379** » Tue Jan 20, 2015 10:41 pm

That's only one possible solution in that long and winding thread.

A better question may be why don't they push a fix or at least a news alert.

new x11 update breaks glx

new x11 update breaks glx
