Windows XP and OS X work around this hardware limitation, most likely by
doing the same thing as the shatter work for Xorg. Basically it splits
the screen into shards and renders them separately which works around
the limitation. However, there is a still a lot of work that needs to be
done for
Regarding Martin's post #62:
Forgive me if this is a dumb question, as I'm new around here -- you say
there's a _hardware_ limitation with the i915/i945 cards and DRI at
2048. Why is it that WinXP can run DX9 quite satisfactorily on the
same hardware? I'm running 2 monitors, 1900x1200

Make that just 915. The 965 supports textures
You're right, I meant to say 915/945. The required texture support is
definitely there for 965, Gx45 and later.

To enable this, you need to patch Mesa DRI driver according to instruction

@aporter: I don't know where the rumors and hunches come from. It is
true that I run out of memory before achieving 4096x4096 resolution but
that results in a decent error message.

Seriously though, I'm not sure what you mean. We are trying to describe
a limitation. If it's a limitation in the hardware, then fine. We
haven't seen anything
The comments in this bug are raising a range of different issues for
different cards (DRI, UXA/EXA accel vs noaccel, different chipsets are
what not). Lumping together a lot of issues mostly makes the bug reports
messy and unusable. There is no point in posting further comments to
_this_
Martin, thanks for the explanation. I sure feel sorry for my not-so-old
laptop with 945, but I know how it works in FOSS world...
PS It would be more honest to set the status to WONTFIX, wouldn't it?;)

I registered for this bug because of this problem on a X4500, which
certainly does support larger textures but is artificially limited to
2048×2048. So this is still a problem for people with i965 and newer
cards that do support large textures. See my comment #51.

@C Snover, you're right. For that hardware you should not be seeing any
limitations of this type at all. Please
Hi,
This Intel DRI limitation, whether it be hardware or driver, still
exists in Jaunty and Karmic.
When I put two 1280x1024 monitors side-by-side, I see:
(EE) intel(0): Cannot support DRI with frame buffer width 2048.
and glxinfo says software rendering
When I put them one-above-the-other,
After reading all the queue bug I have a doubt:
Intel GM945, ubuntu Jaunty, 2 19 monitors of 1440x900 with a total of 2880x900.
It's actually possible with compiz?
Tested with default configuration of jaunty (pretty slow)- Don't work.
Tested with UXA and greedy - Don't work.
Tested with 2.4

Hello,
I'm also interested in this bug, but I just wanted to point out that
you still can use compiz with your dual screen configuration if you
'put' one above the other instead of beside. I know it's a little
messy to work with, but at least it works:
SubSection Display
My symptoms seem to have similar causes, but I'm not sure if this is the
same bug.
I upgraded to the Jaunty RC on April 17, and had decent luck running DRI
and UXA on a dual-screen Virtual 2944x1200.
X did crash every couple of hours, but while it ran, the performance was
great, glxgears

As far as I know, Intel graphics older than the 965 do not support
textures above 2048x2048.
The Intel driver supports textures larger than that on appropriate
hardware already, and has done so for quite a while. Support in Mesa
was the missing part, and has now been fixed upstream.

No dri
The value reported by glxinfo is not accurate. Probably a bug in the
driver. One ugly workaround that works is to edit /usr/bin/compiz and
hard set the value of TEXTURE_LIMIT. So find the line:
TEXTURE_LIMIT=$(glxinfo -l | grep GL_MAX_TEXTURE_SIZE | sed
's/.*=[^0-9]//g')
and change it
