Description Kristopher Ives 2018-12-15 18:36:15 UTC

SUMMARY
Ejecting a CD/DVD drive causes it to open and immediately closes the tray as if something is repeatedly issuing a "close" command to the CD/DVD ROM drive.

STEPS TO REPRODUCE
1. Press the Eject option in Dolphin or run the `eject` command

OBSERVED RESULT
Tray opens and then immediately closes.

EXPECTED RESULT
Tray should open and stay open long enough to take a disc out, usually automatically closed by the hardware itself or until the user presses the eject button again.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: 
(available in About System)
KDE Plasma Version: 
KDE Frameworks Version: 
Qt Version: 

ADDITIONAL INFORMATION
This started on /r/kde on Reddit via this discussion: https://www.reddit.com/r/kde/comments/a69sec/kde_doesnt_leave_my_cdrom_tray_open/

We observed that it does *not* happen if you exit KDE and run the `eject` command manually. It does happen if you run the `eject` command while inside a KDE session. Also does not happen in other non-KDE based distros such as Ubutnu 18.04

Sorry if the location of this bug is invalid it's hard to find the right place for such a bug in KDE.

Thanks Nate.

The sysctl workaround solved the Redditor's problem. Any reason why this happens with KDE but not other distros?

Comment 4 Nate Graham 2018-12-18 04:50:39 UTC

No idea, sorry. If it does indeed happen with KDE but not other DEs, then maybe there is indeed a problem for us to solve. I'll re-open 398465.
