Bugzilla Bug 260325

The X server won't start but initially crashes with this message.

Reproducible: Always

Steps to Reproduce:
1. Follow Guidelines in #251832 and install Xserver 1.5.3 and the rest of the
zoo.
2. Rebuild xorg.conf with 'X -configure'. Reuse that config.
3. Start X. Here you are.

X -configure is mildly broken. Please try running X without any xorg.conf and
please attach the full resulting Xorg.0.log.

Thanks

Unfortunately running without xorg.conf works neither.

well, appending lspci for completeness.

Seems like the built-in configuration falls back to fbdev, which probably
happens because of the crashing intel driver.

xorg.conf - forcing intel

In http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=512200 a reporter says that
this could work with kernel 2.6.26 for now

Xorg.1.log - forcing intel

dmesg happens to say:
[drm:i915_gem_object_bind_to_gtt] *ERROR* GTT full, but LRU list empty
[drm:i915_gem_object_pin] *ERROR* Failure to bind: -12

Well of course it's going to work with kernels <2.6.27 since those don't have
GEM and the driver falls back to older code paths...

Thomas, could you try removing the fbdev driver which somehow seems to have a
higher priority than the intel one?

Oh, and if you have any sort of kernel framebuffer driver (vesafb, uvesafb or
intelfb), please disable them.

Thanks

It even kind of works with kernel 2.6.27 ... however dri won't work:
xserver 1.5.* requires >= mesa 7.3 and that uses GEM instead of TTM which OTOH
requires >= kernel 2.6.28

So with that in mind it becomes clear that we shouldn't go stable with xserver
w/o dri. We need to get X running on kernel 2.6.28 - or we will crash intel
cards.

Nope, xorg-server 1.5 works fine with libdrm 2.3 + mesa 7.2 + -intel 2.4 as
well. I actually recommend this combo if newer versions of the intel drivers
don't work out for you.

I think we'll stabilize the latest versions, but we will definitely keep the
versions I just mentioned for a while, at least until things start to work for
a really high percentage of users.

Thanks

Remi, you are only partly right.

1) yes, xorg-server-1.5.3 also works with mesa 7.1 / 7.2

2) however TTM has been disabled after mesa 7.0.4 ! See commit log for details:
http://cgit.freedesktop.org/mesa/mesa/commit/?h=mesa_7_2_branch&id=eb10cdc838fc31ea2cf59f556f6f7d8b072f5bae

So X will work with the proposition in comment 14, but dri still won't work -
as TTM got disabled...


Any other helping ideas ? - If not I propose to not yet stabilize until this
issue gets a reliable resolution.

> So X will work with the proposition in comment 14, but dri still won't work -

You'll get the old DRI, the one that existed long before TTM. The one that's
been available for the better part of this century. Yes, you'll get the warning
message that will tell you TTM is not available, but it's only a warning. Just
ignore it.

No, we will continue the stabilization effort. We cannot hold back so many
improvements any longer, even if some users are going to be temporarily left
out.

The real solution is to fix this upstream as there's nothing I can do to help
you, I'm just a packager.

Please try the libdrm/mesa/-intel combo I suggested, that should get you a
running system.

Well, Rémi, I did already as you suggested try your combo and the result is
sloooooooow. GLPerformance is dropping from 400 to 25 !

Please consider upstream issues and don't blame all the intel users, only
favoring radeon and nvidia hardware.

Listen, I'm not blaming users, I'm myself very much impacted by all the new
code that's hitting Xorg these days. I have an 855 laptop, I know it's
difficult.

Meanwhile, I want Gentoo to move on, like EVERY distro is doing. I know very
well this upgrade WILL upset some users, it's not something I enjoy doing.
Trust me, I'd rather things were different.

Try to understand *my* point of view when I say I *cannot* support every single
Intel laptop out there. We just can't, not with the resources we have.

So please, if you want to vent your frustration, go talk to upstream. They are
the *only* ones capable of fixing your bug.

Thanks

Oh and for the record, the X11 team's policy is to never ever again get held up
by proprietary drivers.

With that in mind, I don't think it's fair for you to accuse us of favoring
those users...
