Subject: [Bug 247492] Re: glxgears runs unsmoothly when several gear windowsare launched.

As mentioned before on the calls, the issue here is that we are using a videocard with shared memory. the basic system with idling desktop uses up 100M of the available 256M. In the minimal HW configuration this leaves 150M Ram for application usage. The i810 X driver that has to be used due to teh requirement for panning and compression modes will use additional 50M with OpenGL support enabled ...
GL was deliberately disabled in this environment to make sure the system doesnt run out of memory during normal operation. I have a patch pending that will enable GL support on all systems with bigger than the minimal Ram configuration, but it will not be possible to enable GL in the lowest Ram setup without generating a bad user experience.
(This would have been solved with various developments that are currently happening in the 8.10 release using certain Ram compression techniques)
