No hardware surfaces in SDL

Samuel_E_Bray · November 23, 2002, 5:55am

I have already asked this over at nVidia, so please spare me the:

“This is a driver issue, dumbass” response.
Thanks in advanced.

I’ve got this problem, and I’ve had it for a while (actually 2 problems,
but I think they are related)
The first is with SDL, and yes I’ve already asked over at #sdl on
openprojects.net.

I’ve go a Gforce4 MX 440, and the drivers seem to be installed right
(they are in the right place, I can run and compile GL/GLx programs),
however cannot seem to get a hardware surface or hardware accelerated
drawing.

Here is what SDL reports as being available:

Flag: Hardare Surface Available: hw_available = 0
Flag: Window Manager Available: wm_available = 1with antialiasing turned
on everything is super slow (even the most basic AA)with antialiasing
turned on everything is super slow (even the most basic AA)
Flag: Accelerated Hardware Blits: blit_hw = 0
Flag: Accelerated Hardware Blits with Colorkey: blit_hw_CC = 0
Flag: Accelerated Hardware Blits with Alpha: blit_hw_A = 0
Flag: Accelerated Software Blits: blit_sw = 0
Flag: Accelerated Software Blits with Colorkey: blit_sw_CC = 0
Flag: Accelerated Software Blits with Alpha: blit_sw_A = 0
Flag: Accelerated color fill: blit_fill = 0
Video Memory: video_mem = 0K (but I’ve got 64mb of ddr)

Here’s the code that provides the above information:
