Comments/Problems:

<Description of the install, in prose, and any thoughts, comments
      and ideas you had during the initial install.>

Install using speech output. Install goes through fine *until* reboot.
Kernel output is visible - systemd etc. - until desktop starts.
Black screen - speech output still running - can enter username and
password but no desktop display.

system. Adding "nomodeset" on the command line makes things work OK.

We *appear* to also be able to reproduce the issue on a similarly-aged
X1 Carbon 5th gen (HD Graphics 620). Adding "nomodeset" there also
makes things work.

An older x220 with Intel HD Graphics 3000 works just fine.

For completeness: the x260 also breaks on i386 mate installation
without speech.

Testing with i386 and lxqt on the x260: the screen also goes black at
X startup unless we add "nomodeset".

Both systems (x260 and X1 Carbon 5th) work fine when installed as
amd64 systems.

This is a problem with the i915 driver on i386 only.
