I'm using beryl in a laptop with a Mobility Radeon 9700 (01:00.0 VGA compatible controller: ATI Technologies Inc RV350 [Mobility Radeon 9600 M10]). My question is if there's any way of tweaking the GL_MAX_TEXTURE_SIZE value in order to get dualhead configs greater than 2048, which is actually the max texture size my system supports according to glxinfo. Thank you very much. _________________________________________________________________ Un amor, una aventura, compañía para un viaje.

I don't know what the max texture size is for r3xx hardware. Alex > best, > Jerome Glisse > |

Pretty sure that 2048 is a hard limit for maximum texture size for all=20 radeons up to and including r3xx/r4xx, IIRC all drivers for all OS=20 announce this value. So, no, there is absolutely no way you're going to=20 tweak that value, apps really need to take this limit into account and=20 work around it or they will not and are not going to work. Roland |

What does windows annouce for r3xx and r4xx? Is it possible that the 2048 is a hold over from the r200 driver? Alex > > Roland > |
