Title: GtkRadiant - Intel GFX Troubles
Post by: Learts on August 30, 2008, 11:50:55 am

Thanks for the guide, but i have a problem:
When I click on "clipper" or on "select face" and so on I get an error:

"radiant: vbo/vbo_split_inplace.c:97: flush_vertex: Assertion `max_index >= min_index' failed.
Aborted (core dumped)"

?

Sorry for my English, I'm Italian :P

Aah, that's actually a problem with the underlying 3D subsystem and not Radiant. Are you using an Intel graphics chip? I had this problem on the i915 a while ago.

Yes, Intel i815 or i915, I don't remember :|
Damn.

I think this bug may have been fixed - you can try updating or upgrading the DRM and Mesa packages from your distro, but if this doesn't work then you'll need to checkout the latest sources from the freedesktop git repository and build them manually, if you're l33t or feeling lucky.

You can always try and see if you can get Radiant working in Wine <_<

if you're confusing between i810 and i915 i guess that you're using the i810 driver on the i915 chipset (the i810 driver supports i915)
as taiyo suggested already, upgrade Mesa/DRI/DRM, and switch to the intel driver instead, also, try using INTEL_BATCH=1 when using 3D apps (such as tremulous or radiant), it was reported that it gave a really good boost
see your distro's manuals on setting 'global' environment vars

also, sometimes you might get crap with radiant, and also 3D window stacking in general if you have composite and/or AIGLX enabled

PS: erm, maybe split this?

I've checked:

Code: [Select]

00:02.0 VGA compatible controller: Intel Corporation 82945G/GZ Integrated Graphics Controller (rev 02)It's 945.
And I'm using i810 driver.
(Ubuntu 7.10 kernel 2.6.22-14 generic)

About Mesa/DRM, i found this: http://www.intellinuxgraphics.org/download.html, last drivers are dated 25 7 2008..
But i must compile them, aren't anything precompiled for ubuntu? :|

(I agree with espy, maybe a split would be better)

Split, and good luck!

The latest drivers precompiled for Ubuntu are those that come with the Ubuntu development or testing repositories, however installing those would probably pull in half of the development distro as a dependency. You'll get the most up-to-date driver from the freedesktop.org git repository than using the normal downloads - follow the instructions at http://www.intellinuxgraphics.org/download.html

Also, have you tried changing the driver in your xorg.conf? Change Driver "i810" to Driver "intel"

try installing the xserver-xorg-video-intel (http://packages.ubuntu.com/hardy/xserver-xorg-video-intel) package if it's not installed already and switch to the intel driver in xorg.conf like taiyo told you
