3. try to eject the disc via Disks & Devices systray applet

Is this a regression compared to the Plasma 5.19 applet?

no

Phew, I didn't break it. :)

Still, seems important to fix.
Comment 4 Nate Graham 2020-11-26 03:27:40 UTC 
Confirmed.

Comment 6 Nate Graham 2020-11-26 03:31:35 UTC 
This appears to be a distro/hardware/user configuration issue. See https://wiki.archlinux.org/index.php/Optical_disc_drive#Disc_tray_autocloses

I can reproduce this issue on my hardware in the KDE Neon live session, but running `sysctl -w dev.cdrom.autoclose=0` fixes the issue.

The correct solution would appear to ask distros to set this, if appropriate, or figure out why it's not already set.
Comment 7 Nate Graham 2020-11-26 03:36:38 UTC 
Filed Bug 429667 for Neon.
Comment 8 Patrick Silva 2020-11-26 10:01:08 UTC 
I have already added "dev.cdrom.autoclose = 0" to my /etc/sysctl.d/60-cdrom-autoclose.conf file
as workaround to bug 398465, but the bug described here persists. "Disks & Devices" offers no way to eject a unmounted optical disc. The disc is ejected as expected when I press the button of my optical device.

Operating System: Arch Linux
KDE Plasma Version: 5.20.3

Comment 9 Nate Graham 2020-11-28 20:02:49 UTC 
Still, the issue cannot be in the Disks & Devices applet. The issue is deeper, either in Solid (bug 398465), systemd, the device firmware, etc. But there's nothing the applet can do to work around those issues. I guess we can mark this as a duplicate of bug 398465.
