After both patches, that indeed fixes things as soon as X is started, but the
console is still broken. After loading the module, the panel just switches
off, though the console is still usable. Plugging my DisplayPort screen in
also reenables the LVDS panel, although the image is wrapped around by around
100 pixels. (Left part of my prompt is on the right of the screen.)
Wraparound might be related to the different resolution for the ext display;
the external screen only shows the nonwrapping part of the image (and is
therefore missing the first characters of the prompt). Either way that's a
separate bug...
Apart from the above, I now have working graphics (including 3D) on an UEFI
native booted HP EliteBook. I'll clean up my hack VFCT patch and send it to
dri-devel.
P.S.: The laptop also needs your backlight control patch, thanks a zillion for
that - you wouldn't believe how nuts that was driving me.
