getting my hands on relevant hardware is in progress


Note that https://lists.debian.org/debian-boot/2021/04/msg00247.html 
implies the affected hardware is _not_ simply "all AMD/ATI or NVidia 
hardware".  Do we know of hardware that is reproducibly affected?

The problem is that:
the older version of GNOME, or Mate, can work with vesa driver,
while current GNOME cannot.


Do non-GNOME-based desktops work (either KDE, or one of the 
lightweight/for-old-hardware ones e.g. icewm), or is the problem further 
down the stack?


Though even if these do work, the performance penalty of using vesa may 
well be too large for this to be a good solution.

Re: Thinking about a "jessie and a half" release

Would it be possible/reasonable (at least for stretch) to have the 
installer detect this and ask "your hardware appears to be too new for 
this release, would you like to enable -backports?"

As I understand it, xserver-xorg-video-modesetting should be used
instead of xserver-xorg-video-intel, for chips supported by the i915
kernel driver.  So the latter should be changed to limit the device IDs
it claims, then both of them should be backported.


This appears to be causing at least one actual problem: 
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=828087


(The other backports-kernel bugs known to me are 
https://lists.debian.org/debian-backports/2016/06/threads.html#00133 
(appears to be fixed in 4.6) and 
https://lists.debian.org/debian-backports/2016/06/threads.html#00139 (no 
details yet)).

Currently 4.6.0 doesn't work with skylake for me when I plug in a
3440x1440 monitor on a Dell XPS 9550, both with and without xserver-
xorg-video-intel installed.  It never has worked reliably on any kernel
version.  Currently, the monitor works maybe 20% of the time - so if
you persist for 5 boots you've got a reasonable chance of getting
lucky. The only noticeable change from 4.5 to 4.6 is in the kernel
backtraces produced - they have got fewer, and they are only warnings
now.


Have you reported this bug (with the full warnings)?  If not, please do so.
