... even the Intel HD are very conservative in their hardware GPU
implementation :(

For the pre-HD the driver exposes an OpenGL 2 API when the hardware it's
only made for OpenGL 1.4; probably they did this to run Vista/Seven on
these (if you turn off the aero stuff, of course :D). My toughbook was
indeed sold with vista and is seven compatible!

It makes me mad that doing the same things (simple sprite blits) it's
much more faster using 1.3 than using 2.1 (tested with SDL vs SDL2).
Probably just enabling 2.0 switches on some software emulation even for
the same things!

Too bad that except for the high-end CF-31, the panasonic ruggeds always
have low power gpus (for both battery and thermal issues... since they
have no fan and run forever from batteries)

The last consumer grade laptop (AMD APU, something like an i3 with an
embedded GPU) however survived about 8 months on the field :P hydraulic
oil and cheap plastic don't mix very well! Even the APU is *way* better
than the intel HD... the intel HD is usable unless you ask for a lot of
tracks. Then it's *way* faster to use the wx/GTK view (which is IMHO
prettier but that's a personal opinion)

Also got random reboots with the HD; seems to be thermal issues because
it became *really* hot!

Morale: don't get an intel gpu if you ever want to use the gpu.

Still can't use the opengl pcb mode :(((

End of rant. On the list so people will in future know that they will
have issues with intel gpus. Like they have with AMD gpus and OSS
drivers for other reasons...

CAN'T THEY DO A FSCKING WORKING GPU without having to hack the drivers
to get them installed?!
