I've tried this I can't seem to get it to work. I can see in xorg_log
that I got the git master version of xf86-video-intel so I think it's
because the bits from the drm tree is not getting installed correctly.
I have provided some feedback on the drm installation instructions below.
I also have two questions:
1) I was under the impression that with DRI=false in xorg.conf then
the libdrm bits is not used? Did I just misunderstand that?
2) When I build the drm tree I see drm.ko and i810.ko but with a
G45 I won't be using i810.ko right? For G45 I typically will use
i915.ko, on? Is that not built from this drm tree?
Feedback on the installation instructions in README for the drm tree:
I would like to see the following changes if possible:
Don't write "run configure" because configure doesn't exist. Instead say
that --prefix etc should be passed to ./autogen.sh (isn't that what
they mean anyway?)
It says I should copy the *.ko into:
but I believe the target location was updated in 2.6.27 to (maybe mention both
locations for a while but certain .27 location should be mentioned at least):
It would be very useful with some method for verifying that the installation
went well. Even if I "modprobe drm" with no error, how can I tell if I got
the new version of that module loaded? For example, what if I got the prefix
wrong and it's loading my old distro version?
