direct rendering results in black screen, voodoo3, xorg 6.9.0

hi there everyone,

i have recently tried to get the direct rendering extension for working on my 3dfx voodoo3 card. i have recompiled the kernel (2.4) and its modules (including the kernel dri manager and the appropriate tdfx module) and enabled the dri extension in xorg.conf. however, when i execute startx (both as user and root), all that happens is that the screen goes blank and nothing more.

i have already tried other solutions (ie reducing colour depth to 16 bit, etc) but to no avail.

any ideas?

thanks in advance.

ps, using slackware 10.2.

Is X picking up the driver? check the log to see what its actually using. Did you specify the correct driver in the config for the graphics card? also if the module actually in the kernel does lsmod list it?

Sorry if this is what you've already done, but gotta ask.

thanks for the quick response!

obviously at the moment i'm running X without dri, but i tried another attempt with dri enabled in xorg.conf, and here is what happened:

agpgart and tdfx (EDIT plus tdfx_drv now ) are both loaded modules, but lsmod says that they are both unused. when compiling the kernel i tried to get drm as a module so as to follow instructions completely, but it would only compile built-in.

<<edit>> i discovered that you have to compile the drm kernel modules yourself (duh!), so i have now done that and X starts well. it also says in the Xorg.0.log that direct rendering is enabled. however, when i run glxinfo it still says that it is disabled, and a test run of graal (which indicates whether you have direct rendering enabled or not on startup) gives the same output. the 'vendor' string of the glxinfo output still gives Mesa etc etc. help, please!
