Gentoo: Please select pinentry-gnome3 as default pinentry provider

Create `/run/host/etc/portage/package.use/gcr` with the content of: app-crypt/gcr gtk
app-crypt/pinentry gtk

Then rebuild: `sudo emerge -avuDN @world`. Now `eselect pinentry list` should also list `pinentry-gnome3`. To select it:
sudo eselect pinentry set pinentry-gnome3

X forwarding from a distrobox on a remote host

X11 connection rejected because of wrong authentication.

Assuming ssh is set to allow X11Forwarding, on a remote host .Xauthority will be created. But if you enter a distrobox on the remote host, the file can't be found. So in distrobox, export `XAUTHORITY` to point to the host's .Xauthority
distrobox-enter archbox
export XAUTHORITY=/run/host/home/username-on-host/.Xauthority
xeyes
It also works same when waypipe is used.

tigervnc: Service deactivets immedietly after start

cd /etc/X11/Sessions
mv Xsession Xsession.backup
ln -s fluxbox Xsession
