bitcoin-qt QXcbConnection: Could not connect to display

[walletscat]

After the installation process I receive a notification

Code:

"Warning: The home dir /var/lib/bitcoin you specified can't be accessed: No such file or directory
Adding system user `bitcoin' (UID 113) ...
Adding new group `bitcoin' (GID 122) ...
Adding new user `bitcoin' (UID 113) with group `bitcoin' ...
Not creating home directory `/var/lib/bitcoin'.
bitcoind.service is a disabled or a static unit, not starting it. "

I started opening bitcoin-qt unsuccessfully

Code:

" sudo bitcoin-qt
QXcbConnection: Could not connect to display
Aborted (core dumped)"

I'm using Ubuntu 16.04
user sudo but not root
Is there any way to solve this problem?

How exactly did you install bitcoin core on ubuntu? Is your main OS Windows 10?

If you can't connect to a display, and you're running ubuntu localhost, you'll need to install a X-server.

https://sourceforge.net/projects/vcxsrv/

Then run something like

Code:

echo "export DISPLAY=localhost:0.0" >> ~/.bashrc
. ~/.bashrc

Just tried and it worked for me.
