Dennis,
if your 2nd email is to be believed, you are indeed using Ubuntu 18.04, which will be 18.04α.
1) How did you attempt to install GQRX? What hardware
platform is in use?
2) If you wish to run GQRX under Ubuntu, why not run Ubuntu 16.04, which is the most recent LTS (long term support) version?
Alpha versions of operating systems (OSes) are great fun to play
with, but not to be relied upon for anything that matters to one.
An alpha install is really a trash install, since one can not rely
upon the underlying structure not to change by the time the OS
version gets to release.
3) The error message seems to indicate that one is attempting to run GQRX as root, rather than as a normal user. [For stuff like this, your favourite search engine is your friend!]
Cheers,
Robin, G8DQX

because I don't have a 16.04 machine available.

somebody is trying to execute a GUI application over a remote ssh
connection. But I assume that is not the case, because if it was, you
would have mentioned that "little detail" in your mail.
In any case, this error is unlikely to have anything to do with gqrx,
surely you get the same error when trying to run other GUI
applications also?

If I try to run Gqrx in Wayland, I get the following error:
potentially break all Qt applications would make it into a release.
AFAIK there are ways to run X in Wayland and I'd assume that this is
enabled by default in Ubuntu.

There are some errors, because some ppa's are not available for 18.04,
but Gqrx starts fine.

Dennis,
1) The PPAs that you are using will not yet have packages for Ubuntu 18.04 (Bionic Beaver)
2) Unless you wish to compile GQRX from source—which is a lovely learning experience in itself—you are far better off installing Ubuntu 16.04 LTS on the host machine, if running GQRX is your prime aim.
If the machine is yours, then you may wish to establish 2 or more partitions for OSes, should you really wish to run a pre-release version of Ubuntu.
If the machine belongs to someone else, then one might either talk them in to installing 16.04, or yourself install 16.04 to a bootable USB device.
If you're not very familiar with installing Ubuntu, the process is very painless these days, though one does need to keep one's wits about one! You'll waste far less time installing 16.04, and then installing GQRX on top of it. As you have discovered the hard way, the GQRX PPAs do not yet formally support Ubuntu 18.04, which is itself not yet stable.
Running on 16.04 reduces the number of things to be debugged.
3) Another possibility for the display problem is somewhere in Wayland, unless you have switched to the native X-server option.
4) Although Alex Fasching installed 18.04 in a VM, that VM will be using a virtual display, and be running on top of a well debugged OS.
Of course, "You pays your money and you takes your choice". The rest of it is up to you!
Cheers,
Robin, G8DQX

packages for bionic. Maybe I will build for it.

See the attached screenshot for that. I wouldn't expect it working very
well though.
Do other GUI applications, specifically Qt applications, work?
