I tried to get AIGLX to work on my Thinkpad yesterday. AIGLX is an API similar to XGL, but is a better implementation. Unfortunately AIGLX requires implementation by the video-card driver (which is good because it allows more performance), but the proprietary drivers of ati still doesn’t support it. (nvidia’s do, note to myself: get nvidia next time).
So I had to revert to XGL. A lot has changed since the last time I installed XGL. Other gentoo overlays, other windows managers, other hacks.
I used the gentoo-xeffects overlay to get Xgl.
Installing Xgl was a lot more straight forward and less of a problem than it used to be. An emerge and writing a simple startxgl script was enough.
The compiz-quinstorm patchset seems to have evolved to a proper branch of the compositing window manager, now called Beryl. It also includes a nice settings manager now.
Even hibernation and suspend finally seem to work. 🙂
One thing left to do: integrate Xgl into xdm.
