Public bug reported:

When I updated my system today (
), logged off and logged in, the GPU rendering stopped working. Now
using glxinfo it outputs:

Before libegl1 was required I hadn't it installed, but as now it is
unavoidable, it became a big problem.

The only way to make GPU rendering work on this machine is to create a
xorg.conf file at /etc/X11 and use the driver intel, but it is said this
is not recommended to use it with hardware newer than 2007.

Intel Core i3-6100U
Intel HD Graphics 520
8 GB of RAM

  If libegl1 is installed, modeset fails and rendering falls back to CPU
