In particular, according to what I understand from http://marc.info/?l=freebsd-current&m=133341372825281&w=2 helping with the brightness seems to require a quite broad understanding of ACPI and/or EC, and maybe also a good overview of how things work currently in FreeBSD. Both of these seem to be far beyond anything that I can reach in a reasonable amount of time :-( Still, my offer stands, and if anybody can think of anything useful I can do or learn, please don't hesitate to tell me so. > Good news is that Konstantin's latest patch works with FreeBSD 9-STABLE so > no longer need to run HEAD. I would love to see resume work, though. I'm not sure whether this is the right place to ask for such help, but I haven't been able to get it working as much as I would like. More specifically, I checked out 9-STABLE, and merged all 14 commits listed at the end of http://wiki.freebsd.org/Intel_GPU I then added WITH_NEW_XORG="YES" and WITH_KMS="YES" to /etc/make.conf and compiled x11/xorg metaport with default options, except for KMS=on for graphics/libdrm. It seems that adding i915kms in /boot/loader.conf freezes the system, but that's only a minor inconvenience. Now I kldload it just before starting slim. The screen resolution is correctly detected, everything in Xorg.0.log and `dmesg` looks fine, DRI2 is enabled, xdriinfo reports i915 dri activated for the screen. Well, all in all, as far as I can tell everything is fine, except I don't see any acceleration : it takes up to a whole second for my rxvt-unicode to refresh its 80x56 window (whether scrolling or switching tmux window, and no image background is set), opaque window moving is very jumpy (but I can live without it), and armagetron runs at 7-12 fps (to test whether 3D acceleration fared better than 2D acceleration). Do you see the same behavior? Would you have any idea on how to diagnose whatever could be wrong? Thanks for your help, Natacha Porté
