I have a lenovo S9e running Intel integrated graphics. Here is my lspci output related to the graphics:

00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller (rev 03)
Subsystem: Lenovo Device 3870
Flags: bus master, fast devsel, latency 0
Memory at f0580000 (32-bit, non-prefetchable) [size=512K]
Capabilities: [d0] Power Management version 2

I want to know how I can make sure OpenGL support is running in full on an Ubuntu 10.04 installation. I have a few hints to think that it is not:

The "Desktop Effects" will not load
Apps such as stardock, when attempting to use OpenGL rendering, will display black boxes instead of transparency
In the games Pioneers, the number-tile icons are suspiciously just black circles
Windows games running with Wine will only support software rendering, not hardware rendering
When I boot into a Knoppix LiveCD, the desktop effects do work, splendidly, meaning compiz detects my computer as capable.

My problem with troubleshooting is that Canonical has basically eliminated the conf-file-based mechanism of X11 as far as I can tell, thus making it even harder to ensure graphics modules are loading properly.

How do I debug and test OpenGL on m Ubuntu 10.04 installation?
