It is an older Dell XPS X2 laptop (5 years old) with 2 graphic cards.
Intel and nvidia. I am using the nvidia as I have a second monitor and
the only way to make it work is by using the HDMI output (nvidia should
be on). The processor is second generation Intel (Sandy Bridge) and the
intel card may be on it.

Experimented with turning off Open CL and it looks like the speed
improved. My security patches are up to date as released by ubuntu.
What kind of hardware? A 'real' video card (nvideia, radeon) or a
'fake' (intel or built in the cpu?
They did some changes to the opencl to turn off if it is a 'fake'
video card.
• OpenCL: properly discard CPU-based OpenCL devices.
