[SOLVED] Issues with xorg-server and intel 945 (i915)

segmentation_fault · 11-13-2013, 02:41 PM

After last saturday's update the x server doesn't start with the following errors:

Code:

I have xorg-server-1.14.3-r2 and xf86-video-intel-2.99.905-r1 This also happens with r1 server and the last stable intel driver (2.21.15)
The kernel is 3.12.0 with KMS enabled. The use flags for the packages are:

Code:

$ eix xorg-server
[...]
     Installed versions:  1.14.3-r2(08:25:16 PM 11/13/2013)(nptl suid udev xorg xvfb -dmx -doc -ipv6 -kdrive -minimal -selinux -static-libs -tslib -xnest)

$ eix xf86-video-intel
[...]
     Installed versions:  2.99.905-r1(10:15:15 PM 11/13/2013)(dri glamor sna udev uxa -xvmc)

I added the glamor flag at intel driver to test if it made any difference. I am happy to provide any more info needed.
Thanks in advance.

You should use wgetpaste and post the link to full Xorg log. Also, emerge --info output could be helpful.

segmentation_fault · 11-23-2013, 03:27 PM

Ok, here is the latest xorg log http://bpaste.net/show/152456/
and here is emerge info http://bpaste.net/show/152457/

Emerson · 11-24-2013, 07:41 PM

Simple things first, you did

Code:

emerge @x11-module-rebuild

?

segmentation_fault · 11-25-2013, 04:28 AM

Yes, I did that. And after changing kernel I did emerge xorg-server and then @x11-module-rebuild.
In the meantime kernel was upgraded to 3.12.1 , still no X.

Emerson · 11-25-2013, 06:01 PM

Alright, undefined symbols error pops up when kernel and display driver do not match. You sure you had your /boot mounted when you upgraded your kernel?

segmentation_fault · 11-26-2013, 09:19 AM

It's not on a separate partition, so it was mounted. I can confirm the running kernel with uname. This has happened before but it was resolved by dowgrading the intel driver. This time, however, I can't find a working combination.

Emerson · 11-26-2013, 09:06 PM

Do you still have the same issue with USE="-glamor"

segmentation_fault · 11-27-2013, 06:03 AM

I am trying now with -glamor and will post back.

EDIT:
Nope, still getting errors. Here is the latest xorg log http://bpaste.net/show/153490/
However, previously I got

Code:

Failed to load /usr/lib/xorg/modules/drivers/intel_drv.so: /usr/lib/libglamor.so.0: undefined symbol: glamor_egl_make_current

but now

Code:

Failed to load /usr/lib/xorg/modules/drivers/intel_drv.so: /usr/lib/xorg/modules/drivers/intel_drv.so: undefined symbol: vgaHWGetIndex

and on both cases

Code:

[  2144.323] (II) LoadModule: "glamoregl"
[  2144.323] (II) Loading /usr/lib/xorg/modules/libglamoregl.so
[  2144.492] (EE) Failed to load /usr/lib/xorg/modules/libglamoregl.so: /usr/lib/libglamor.so.0: undefined symbol: fbCreatePixmap

Is it possible that there are some left-over files causing a conflict? Can I get rid of them somehow to try a clean install of intel module?

revdep-rebuild should tell if there is cruft left behind.

Revdep says it's ok. Also did depclean and then revdep again, just to be sure.

After yesterday's updates X works again. The working combination is
kernel 3.12.2
xorg-server 1.14.99.903
xf86-video-intel 2.99.906

I am marking this as 'solved', however I don't know what was wrong. Perhaps it is due to linux-headers update to 3.12 which was just now released even in ~arch.

Emerson · 12-04-2013, 07:01 PM

For sake of clarity, the only package that depends on linux-headers on a Gentoo system is glibc. Once glibc is rebuilt with new headers the upgrade will be imminent.

segmentation_fault · 12-07-2013, 11:49 AM

It's broken again, after upgrading to xorg-server-1.14.99.903-r1
Same errors on Xorg log. Even downgrading doesn't fix it. I think this time glib or glibc was also upgraded, I don't know if it is relevant. I tried rebuilding both of them and then xorg-server and modules, still no change. I also recompiled the kernel, deleted the matching /lib/modules/x.x.x and reinstalled them. I just can't figure out what is going wrong. I'm thinking about wiping the disk and start over again.

segmentation_fault · 12-07-2013, 12:07 PM

Somehow it worked. I recompiled glibc, glib, xorg-server and xf86-video-intel in that order and worked again.
