Bug Description

The MAX_TEXTURE_SIZE reported by the dri drivers shipped in Breezy for my ATI
9200mobility is 512. The actual value is 4096 (or so).

This may be something upstream, and if so I apologize as I'm not sure where such
a bug should be posted.

This is still the case for Dapper.

1024 in Ubuntu 6.10 edgy with 9000mobility. And it's definitely not 4096, only the very newest cards (NVIDIA 8800GTX / Radeon X1900) support bigger than 2048x2048 textures I think.

Still a problem in feisty,

It should be 2048x2048 for a mobility 9000 in a Latitude D600 (I checked in windows)

Hmm, might be actually fixed in hardy, or then I cannot undo my own fix... anyway, the workaround was to put:

<option name="allow_large_textures" value="2" />

in /etc/drirc. But it'd be good to get a verification that in a clean hardy glxinfo -l | grep GL_MAX_TEXTURE_SIZE is indeed 2048 without any changes.

The actual package might be libgl1-mesa-dri instead of xserver-xorg-video-ati.

Yep, booted from Ubuntu 8.04 alpha 1 CD, max texture size is now 2048.
