I did a little investigation of my problem and saw this: xorg-server-1.5.3-r6 has a library called This library uses drmOpenOnce(NULL, "pci:0001:01:08.0", ...) to get the graphics card. lspci reports 0001:01:08.0 VGA compatible controller: ATI Technologies Inc Radeon RV250 If [Radeon 9000] (rev 01) So the PCI Bus ID seems to be correct. libdrm-2.4.5 has the function drmOpenOnce(). This function goes down to drmOpen(NULL, "pci:0001:01:08.0") and drmOpenByBusid("pci:0001:01:08.0"). Now drmGetBusid(fd) is called and returns "pci:0000:01:08.0". Which is wrong, because it differs from the original PCI Bus ID. So my graphics card will not be used with hardware accelerated OpenGL. drmGetBusid() calls the kernel module drm via IOCTL DRM_IOCTL_GET_UNIQUE. (see file drm_ioc32.c). So is it a bug in the kernel? Whom can I report this? Thanks for any suggestions Johannes -- ------//-------------------------------------------------------------- // Johannes R.
