Loading DRI modules

ConnorBehan · 2007-07-28 04:51:39

Perhaps I'm getting a bad reputation for asking questions about DRI... but http://dri.freedesktop.org/wiki/Building says to add these lines to modules.conf

pre-install <drm module> /sbin/modprobe "-k" "agpgart"
pre-install agpgart /sbin/modprobe "-k" "<agp chipset driver>"

For me that would be:

pre-install r128 /sbin/modprobe "-k" "agpgart"
pre-install agpgart /sbin/modprobe "-k" "intel_agp"

What is the modules.conf file in Arch... is it rc.conf? Back when I used ubuntu, the folks told me that I should just type r128, agpgart and intel_agp in the modules file and not worry about the preinstall command (although I could never get DRI to work).

I know I will not have to compile a thing on Arch... I will get the latest version of X.org when I install it. I will also get libdrm, libgl-dri and mesa and these packages might have scripts that take care of the modules already... Does that mean I can skip this step entirely?

Try something like this in /etc/rc.conf...

# Modules to load at boot-up (in this order)
#   - prefix a module with a ! to blacklist it
#
MODULES=(intel_agp agpgart r128)

Wow that's pretty simple. I guess the freedesktop building instructions give lines that are most likely to work with most common distros. People have also told me to load the drm module.

lsmod says agpgart is used by drm and intel_agp, intel_agp is used by 1 module and drm is used by r128. Does that sound correct? Can someone with DRI verify that agpgart is used by their chipset agp and drm, their chipset agp is used by 1 module and drm is used by their driver?

Sounds about right - I'm using proprietary drivers but I've got a similar output.

Thanks alot, I have the install CD burned (and lightscribed) and im beginning to backup files... Can't wait to install Arch

Oh, question! These kernel modules have to be loaded while booting because they are not included in the vanilla kernel. Would a more bleeding edge kernel like -viper, -beyond, or -nitro have these already compiled in properly?
