Dear Maintainer,

booting to Debian Installer fails on a 6th Generation Lenovo ThinkPad
X1 (type 20KH-006MMX) with the following symptoms:

* Boot from a Debian installation media (mini.iso 2018-05-18 on a USB
  drive). Also tested with Wheezy, Jessie, Stretch and Testing amd64
  ISOs.

* GRUB menu (version 2.02-2) shows options "Install", "Advanced
  options" and "Install with speech synthesis".

* On entering "Install", the screen goes blank. The machine is still
  powered on and the keyboard leds respond to, e.g., the "mute"
  button. Switching to virtual terminals does not help as the screen
  appears dead.

Similar problems with a blank screen have been reported on earlier
versions of the ThinkPad X1 (see
https://bbs.archlinux.org/viewtopic.php?id=210007) with workarounds
involving boot parameters intel_pstate=no_hwp or
intel_pstate=disable. In this case, this does not help. Also, the bug
appears on several kernel versions (from 3.16 in Jessie).

Booting to a live environment using debian-live-9.3.0-amd64-gnome.iso
is not affected by the bug. The live system uses a full 2560x1440
resolution on a 4.9.0-4-amd64 kernel. However, the "Install" option on
the same ISO results in a blank screen.

Awesome - thanks for confirming. Closing this bug now.
