help getting hw-accel OpenGL on Pismo
I'm running Debian Sid on my Apple "Pismo" Powerbook G3 Firewire.
I'm trying to get hardware-accelerated OpenGL working. The Powerbook
comes with an ATI Rage 128 Mobility M3, 66 MHz AGP 2x (rev. 02) bus
and the card has 8 MB SDRAM. Standard 1024x768 display.
glxinfo is telling me that there is no Direct Rendering, and also says:
OpenGL vendor string: VA Linux Systems, Inc.
OpenGL renderer string: Mesa GLX Indirect
OpenGL version string: 1.2 Mesa 3.4.2
Not sure if this is helpful or not, but lspci tells me:
00:10.0 VGA compatible controller: ATI Technologies Inc Rage Mobility M3 AGP 2x (rev 02)
I'm using the current 2.4.22-ben2 benh kernel (thanks Ben!) and it's
configured to use:
Console Drivers --> Frame-Buffer Support:
CONFIG_FB (Frame-buffer support *experimental*)
CONFIG_FB_OF
CONFIG_FB_CONTROL
CONFIG_FB_CT65550
CONFIG_FB_ATY128
Character Devices:
CONFIG_AGP (/dev/agpgart)
Apple UniNorth Support
CONFIG_DRM (Direct-Rendering Manager -- Kernel-level support for DRI)
and it says I should use CONFIG_AGP.
CONFIG_DRM_R128
Regarding my XF86Config-4, in my "Module" section, I'm loading (among
other things) GLcore, dri, & glx.
Other, possibly relevant sections look like:
