Over time the software packages we use evolve; normally adding support for new hardware and features, and occasionally doing spring cleaning to drop support for old hardware. The version of mesa we use in LE11 (mesa is responsible for 2D graphics like the Kodi GUI) has done spring cleaning since the version used in LE10 and the GMA950 card appears to be one of the casualties.
Options are:
a) Custom image that uses an older (pre spring-clean) mesa version
b) Disable onboard video (if possible?) and use a newer supported card
c) Stick with LE10
A is not guaranteed to be possible, but also not hard to try if you have some self-building skills. If tempted with B, pick a newer Intel or AMD card, not nVidia (else you are forced to use the Generic legacy version of LE). C is the easy option.
