Tim's driver was merged into cvs a while back. > My X log has this to say: > (EE) SAVAGE(0): Memory manager initialization to (0,0) (1024,478) > failed > (==) SAVAGE(0): Backing store disabled It looks like you don't have enough memory for the mode/colordepth you want to use. try a lower res/depth or allocate for videoram in teh bios if you can. right now the driver just blindly allocates space for front/back/depth and textures. if you don't have enough space the back buffer could allocate part of the front buffer which looks like what happened in your case. I'll be adding some checks to make buffer allocation more sane at some point soon. > > And /proc/mtrr reads thusly: > reg00: base=0x00000000 ( 0MB), size= 256MB: write-back, count=1 > reg01: base=0x0f800000 ( 248MB), size= 8MB: uncachable, count=1 > reg02: base=0xd8000000 (3456MB), size= 8MB: write-combining, > count=2 > reg03: base=0xde000000 (3552MB), size= 16MB: write-combining, > count=1 > reg04: base=0xdc000000 (3520MB), size= 32MB: write-combining, > count=1 > reg05: base=0xda000000 (3488MB), size= 32MB: write-combining, > count=1 > > X is running at 1024x768x32. > > 2) Fullscreen 3D stuff (TuxRacer) creates snow; windowed stuff > creates > both snow and blinking artifacts on the lower half of the screen (it > looks almost as if some double-buffered memory is being overwritten). > Is > this 'normal' (being in development), or is something wrong with my > setup? This is probably do to the back buffer wrting on the front buffer for the above reason. Alex > > Thanks! > > - Chris K > __________________________________ Do you Yahoo!? Yahoo!
