Yes. Multiple times. Installed Debian Sid - armhf and arm64 - multiple times, as well as Kali current - armhf and arm64. I installed both through the manual way and the GUI way. The "waiting for xwayland" screen does display afterward, which I imagine wouldn't happen if qxdisplay wasn't installed? I did double check by running this in the folder where those rpm files were downloaded: Code: devel-su zypper install lxc-templates-desktop-1.1-4.noarch.rpm qxdisplay-0.1-2.armv7hl.rpm harbour-containers-0.4-1.armv7hl.rpm It said they were already installed and there was 'nothing to do'.
devel-su zypper install lxc-templates-desktop-1.1-4.noarch.rpm qxdisplay-0.1-2.armv7hl.rpm harbour-containers-0.4-1.armv7hl.rpm
