Xorg dri problems, intel "failed to initialize TTM" [EXPLAINED]

Hi everybody,

I know this is sort of like double posting, but my issues are with different cards on different computers, so I think this is appropraite.

Now i have an intel 82845G/GL "brookdale" intel onboard graphics controller.  Post Xorg upgrade, I could get say, 700-900 fps in glxgears, with no error messages, now post-upgrade I've noticed:

1) If I don't specify modes in my xorg, xorg will make bad choices for the defualt resolution which will cuase Xorg to completely lockup unless I use the vesa driver or the NoAccel option.  That's not too bad, I can fix this by specifying modes

2) I get a new error message when running glxgears:

Failed to initialize TTM buffer manager.  Falling back to classic

3) For some reason, when I open a Terminal after starting xfce a (random?) character will be repeated as input until I hit the backspace key, after which things seem fine.  This doesn't happen if I open another terminal.  (that's the xfce-terminal, to be precise).

Here's my Xorg.conf:

Note that before I specified:

    Option           "AllowEmptyInput" "off"

I couldn't get input devices to work anywhere near properly, probably becuase of the new hotplugging being enabled. 

I've tried with a color depth of 16, but this doesn't seem to help.

And here some excerpt from Xorg.0.log, these are out of order from which they appear, warnings are listed first, then errors:

I've tried "xaa" mode rendering, but this doesn't seem to improve things.

It looks like I still have some problems with my input devices, but since they are more or less working, I'm not extremely concerned about the errors regarding keyboard, mouse, and kvm switch, I think the warings and the last error might give some clue as to why I'm having trouble with acceration.  Any advice will be appreciated.

On the plus side, I can finally get Xorg to default to starting 1600x1200 mode.

Re: Xorg dri problems, intel "failed to initialize TTM" [EXPLAINED]

Hmm, I get the same error when running glxgears

Re: Xorg dri problems, intel "failed to initialize TTM" [EXPLAINED]

TTM has been removed in the intel xorg driver, GEM is replacing it, but needs support in the kernel (it should be in 2.6.28). So you fall back to classic.
See the following gentoo bug: http://bugs.gentoo.org/show_bug.cgi?id=237468
I can alleviate the performance loss slightly with the following ~/.drirc:

Re: Xorg dri problems, intel "failed to initialize TTM" [EXPLAINED]

TTM has been removed in the intel xorg driver, GEM is replacing it, but needs support in the kernel (it should be in 2.6.28). So you fall back to classic.
See the following gentoo bug: http://bugs.gentoo.org/show_bug.cgi?id=237468
I can alleviate the performance loss slightly with the following ~/.drirc:

<driconf>                                                                                                                                                                 
  <device screen="0" driver="i915">                                                                                                                                       
      <application name="Default">                                                                                                                                        
            <option name="vblank_mode" value="0" />                                                                                                                       
      </application>                                                                                                                                            
  </device>                                                                                                                                               
</driconf>

So basically, the latest upgrade removes functionality for intel cards until 28 is out?

Re: Xorg dri problems, intel "failed to initialize TTM" [EXPLAINED]

I wouldn't say that functionality is removed, more exactly performance is degraded. This comes from a lack of coordination  in the development of the kernel and of the xorg driver. Obviously this concerns upstream, archlinux as a distro is totally innocent

Thanks for the info, patrocio7, you wouldn't happen to know if this would effect cards using the "r128" driver as well, would you?

Does anyone know when the 28 kernel is expected to hit testing? Considering whether to downgrade until then.

What are benefits of GEM?

Because I have Mandriva Cooker with 2.6.28 rc5 kernel, Intel Driver 2.5.1, latest mesa, xorg and libdrm packages and performance is horrible.

Re: Xorg dri problems, intel "failed to initialize TTM" [EXPLAINED]

As you can see in the gentoo bug report the sequence of steps needed to enable GEM is quite complex, so I am unable to say if in Mandriva you are actually using GEM. Moreover I have never used GEM, I have only read that it should restore the performance which was given by the old i810, with less bugs and a more solid architecture.

I  have same problem.
Why does we have intel driver 2.4.3? Acceleration won't work even after upgrading to the kernel 2.6.28. This driver useless for Xorg 1.5.

Re: Xorg dri problems, intel "failed to initialize TTM" [EXPLAINED]

Acceleration works(but the performance is slower), dri is enabled, and this driver is expected to be much less buggish than the previous releases of the driver. Moreover it is released and arch adopts always the most recent working releases. You should complain with upstream, not with the distribution.

Where does the file .drirc need to go? I see somewhere refered to as ~/ all the time but still haven't figured out where it actually means? /root?

It goes in ~/.drirc as stated above. "~" will always be the home directory of the current user. So if you are logged in as root it is "/root", if you are logged in with your normal user it will be "/home/username".

Re: Xorg dri problems, intel "failed to initialize TTM" [EXPLAINED]

So. I upgraded on kernel 2.6.28-rc7 - no positiv effect

As far as I know we need also libdrm-2.4 and intel-driver 2.5, both not in tree.
Okay, Arch is using the current official release, that is okay. But way we use a official release, if we know that their is a major failure in it?
80% of laptops and 50% desktops computers are now not usable for 3D applications...

If I know firefox-3.2 has a big security problem it will not add it to my distro, even when it is officially released?

Re: Xorg dri problems, intel "failed to initialize TTM" [EXPLAINED]

Stop calling features bugs please!!! Go "blame" the the intel devs for being so stupid as to make their driver modern and make use of enhanced stability. Maybe first investigate about something before making claims. If you want performance and less complex systems - use Windows!

It seems most people still don't get that open source means constant DEVELOPMENT! And that it actually is a good thing.

And if you had investigated a bit more you'd have known that only kernel 2.6.28 won't be enough but GEM needs to be enabled in mesa, libdrm, intel-dri as well. If you want to use that, have fun using -git releases (available in AUR). And goddam stop whining about features!

as I found here ( http://marc.info/?l=dri-devel&m=121127531521174&w=2 ), GEM is no better than TTM
then why to replace it>

What you are suggesting is pure insanity, that I have been running away from when I switched from gentoo to Arch.  From a software engineering perspective it a clear mistake of intel devs to release their driver in this state, while none of the dependencies have been released.  It is plainly rude towards users.  Software is not for devs but for users.  Any dev forgetting that is shooting his own feet.

I admire and appreciate that intel devs work on this driver and make it available for us - this does not mean they do not make mistakes.  And this is clearly a mistake for me, as far as I can see.  This mistake has likely cost more time of users (in total) than these guys have spent developing the driver release.

Re: Xorg dri problems, intel "failed to initialize TTM" [EXPLAINED]

Perhaps we should be careful with words. It is not true that the dependencies of the driver have not been released. The intel driver works with classsic buffer management. The GEM stuff is required to enhance performance, but this is not what is usually considered a dependency. Nonetheless I understand that it is awkward to abandon an old system when the new one is not ready, falling back to something even older. Anyone somebody with some technical specific skills on the subject should complain with upstream (the distribution is TOTALLY innocent, because there are no bugs, no security risks etc. and so it is right to follow upstream)

dito...

other distros have exactly the same problem. In Ubuntu my 3D performance is even worse...
Fedora (or Fedora Rawhide) uses a GEM-patched Kernel as far as i know. The peformance there is fairly decent (as far as i read)

Re: Xorg dri problems, intel "failed to initialize TTM" [EXPLAINED]

Ok, some explanation:
- libdrm 2.4.1 and xf86-video-2.5.1 are buggy. And by buggy, I mean buggy. You don't want those on your system.
- The TTM message is useless. I'll patch it out of the next intel-dri release
- TTM is dead, it was replaced by GEM before it made it into the kernel and the server. That's why DRI2 got delayed.
- The Vblank setting limits your framerate by turning on VSync. This should not affect performance, because you can't see the higher framerate on the screen anyways.

I had reports about broken DPMS when AIGLX is enabled with VSync enabled, so I'm thinking about reverting that default.

most users who run glxgears will do a simple calculation: 1+1=2:
- they get 60fps performance
- there's a weird warning nobody understands
result:
There must be a bug that causes this warning and limits my framerate to 60fps, which is the wrong assumption.

Well, I have stumbled on this page not because of glxgears - I do not care about it.  I stumbled on it because I was tryin to understand why Maryo has become jerky recently.  Of course there could be other reasons, but this looked plausible.

Re: Xorg dri problems, intel "failed to initialize TTM" [EXPLAINED]

I just installed Arch (coming from Debian) on my X61 Thinkpad, which uses the Intel 965G integrated graphics.  In Debian I get about 1000fps in glxgears.  In Arch I get 49fps, with the "Failed to initialize TTM buffer manager.  Falling back to classic." error.

Urban Terror plays smoother in Arch than I have EVER seen it play in Debian.  This error doesn't correlate to any graphics problems on my machine at all.

Thanks ^ JGC
