Re: DRM/DRI accelerated (3D) graphics?
Just to update on the below, after Sending I double-checked if HP AGP
was actually selected in the Kernal config.. which it wasnt, doh! With
that on and hp-agp forced to load as a module that bit is ok, but with
KMS enabled I get no screen and instant beeping error.
With no KMS I get:
[ 275.231] drmOpenByBusid: drmGetBusid reports pci:0000:80:00.0
[ 275.231] (II) [drm] DRM interface version 1.4
[ 275.231] (II) [drm] Mapping SAREA for DRM lock failed.
[ 275.231] (EE) RADEON(0): [dri] DRIScreenInit failed. Disabling DRI.
This is with Emeric's patch on hp-agp , same no matter I think. I think
Ill try the other AGP card again (above still with R300).
