Video display via Thunderbolt docking station (Lenovo/Lenovo)
I recently got a Lenovo Thinkpad P1 gen 2 laptop and an accompanying
Lenovo Thunderbolt 3 docking station. Windows 10 came preinstalled, and
I promptly carved out space for a Debian partition.
Debian installed flawlessly - it went *much* more smoothly than when I
set up my previous Thinkpad! The only thing that didn't immediately
Just Work on the laptop itself was the wireless ethernet adapter, which
required me to install a 5.4 kernel, and that got it working with no
further issues. (Side question: Is there any virtual package I can
install to automatically get updates to the 5.4.x kernel line?
linux-image-amd64 is no help here, since that's tracking 4.19.x instead
of 5.4.)
So then it was on to the docking station, which also mostly Just Worked
with charging, ethernet port, and a USB mouse running through the dock.
But I am having no luck with getting an external monitor to work. The
monitor I'm currently using for testing is connected via HDMI (but I
could also use DisplayPort if that would make things easier) and it
worked immediately when connected in Windows, but Linux just does not
want to see it - no matter how many times I've gone round and round with
nvidia-driver and primus, including installing both from backports,
xrandr continues to insist
$ xrandr --listproviders
Providers: number : 1
Provider 0: id: 0x43 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 3 outputs: 1 associated providers: 0 name:modesetting
and sees only the laptop's built-in screen:
$ xrandr -q
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 16384 x 16384
eDP-1 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 344mm x 193mm
(list of modes omitted)
I suspect that at least part of the problem may be an overly-new
graphics card, as nvidia-detect says
$ nvidia-detect
Detected NVIDIA GPUs:
01:00.0 VGA compatible controller [0300]: NVIDIA Corporation Device [10de:1fb9] (rev a1)
Checking card: NVIDIA Corporation Device 1fb9 (rev a1)
Your card is only supported by the updated drivers from
buster-backports.
See https://backports.debian.org for instructions how to use backports.
It is recommended to install the
nvidia-driver/buster-backports
package.
...even though...
$ sudo apt-get install nvidia-driver/buster-backports
Reading package lists... Done
Building dependency tree
Reading state information... Done
nvidia-driver is already the newest version (440.59-1~bpo10+1).
optirun/primusrun are also currently nonfunctional, as primus conflicts
with the nvidia-driver metapackage. Specifically,
primus : Breaks: libgl1-nvidia-glvnd-glx (>= 0) but 440.59-1~bpo10+1 is to be installed
Breaks: nvidia-driver-libs (>= 0) but 440.59-1~bpo10+1 is to be installed
When I choose to let those packages be removed so primus can install,
optirun/primusrun still fail, due to not being able to locate
libgl.so.1.
So I'm pretty much out of ideas here. Does anyone know what I need to
do to get this working, or at least what the next step would be for me
to make some progress?
