Description Max Staudt 2018-02-15 16:20:56 UTC

Up to now, the 3D driver for the VC4 GPU on the Raspberry Pi is installed by default. This causes the 'modesetting' DDX to activate the GLAMOR acceleration for 2D, which in turn causes the graphics subsystem to run out of memory, and possibly lock up the machine.

Since this is due to hardware limitations in GPU memory management (no virtual memory on the GPU side), let's disable this driver by default by splitting it off into its own package: Mesa-dri-vc4.

This package can still be interesting for someone driving the 3D chip directly, such as in Wayland style applications. But in the standard case of Xorg based desktops, not installing this 3D driver obviates the need for manually disabling GLAMOR on Raspberry Pis.
