glxgears is blank on savage

[Mark Cass]

savage driver team,   when i run glxgears a window appears but nothing is displayed. the shell from which glxgears was run displays the usual frames per second and no other information. i checked glxinfo and dri is enabled. also found nothing unusual in the X log file. i have two options set "APGMode" to "4" and "AGPSize" to "32". i tried without using these options with the same result. the system is using the savage twister with 32 MB and AGP 4X. it is detected and reported as such in the X log file. the X server is running at 1280x1024 and using 16 bit color.   what is strange is that this same code (no recompile, code was compiled on a intel based machine) works on another system i have. this other system is an AMD Athlon processor using a 32MB AGP 4X savage 4 video card. glxgears runs properly (i see gears spinning). i use the same settings for the x server and savage options as mentioned above. i have had dri working correctly in the past on the twister but it was way back in march of 2004. at that time it worked fine.   the code i am using is from an earlier version (before the kernel 2.6, X org change over). i have to use the old driver that works for the linux 2.4 kernel (no choice, blame it on management). i think the version dates back to about May of 2004.   if you have any ideas please let me know.   thanks in advance, mark   ps.   some time ago i worked out the details for texture compression. i did not go as far as to include the 'on the fly' compression stuff. i have tested the loading of compressed textures and sub textures and both perform as expected. if you would like to include this in your latest stuff just let me know and i will post the source code files. all the files are commented quite clearly concerning the changes made.
