Hello,
I try to install debian jessie on a windows 10 It Works TW891 tablet
(with attached keyboard)
using the hybrid 32/64 bits dvd, I could install jessie with xfce.
But... it's installed in portrait mode (the screen need to be seen with
the longer size vertical), when the keyboard expect a lanscape mode, so
it's really unfriendly :-).
I could make the *initial terminal* (text mode), to display in the right
position, adding to the grub2 kernel line:
vga=791
fbcon=rotate:1
video=efifb
nomodeset
may be one of these options is not right, but I couldn't test all. not
the question here, probably.
but as soon as X takes over, the screen fallback to portrait.
xfce panel do not have any option other than "normal" for orientation.
video is intel vga (no other detail)
xrandr --output default --rotate left
fails with "cannot use rotation left"
I could add a mode 1280x800 following

but with "configure crtc 0 failed"
any hint?
thanks
jdd
