In the spirit of being short and sweet, that fits very well with the concepts of Glucose:
- it's an OpenGL based acceleration architecture (as XAA and EXA);
- it uses Software/Xgl code, so it accelerates everything using exactly the same paths as Software/Xgl does, so there's no duplicate code/work;
- all driver code is limited to just initialising it (a call to glucoseDriverInit).
- Xorg will crash if the number of clients reaches zero.
- Changes to the screen geometry via RandR extension are not yet supported.
Source is only available from Git and for Intel cards. You need to follow the instructions to build a modular Xorg, but using instead:
- yuv-porting branch from pixman module,
- master of Software/glitz module,
- glucose-2 branch from xserver module,
- glucose branch from xf86-video-intel module. Then add the following line to the Device section of you xorg.conf:
Option "AccelMethod" "glucose"
If things are slow check on the resulting /var/log/Xorg.0.log for the following (or similar) lines:
... AIGLX: Loaded and initialized /usr/lib/dri/i915_dri.so ... intel(0): Using GLUCOSE for acceleration ...
If either is missing then you're either using glucose with GL software rendering, or no glucose at all.
