SUMMARY Plasma cannot detect CD/DVDs when inserted i.e. an CD/DVD is not shown in Disks & Devices widget and Dolphin. But if it is inserted when the system boots/mount it manually/open k3b/other access to it such as dd, it is detected and shown. Sometimes two identical device is shown in Disks & Devices widget if it it is inserted when the system boots. Automount is enabled in system settings. Tested various CD/DVDs. STEPS TO REPRODUCE 1. *After* the system boots, insert a CD/DVD 2. It is not detected by plasma, but /dev/sr0 exists and no error message in dmesg 3. Mount it manually/open k3b/other access to it such as dd 4. Detected by Plasma OBSERVED RESULT As described above EXPECTED RESULT Whenever a CD/DVD is inserted, Plasma should detect it. SOFTWARE/OS VERSIONS Operating System: Gentoo Linux 2.17 KDE Plasma Version: 6.3.5 KDE Frameworks Version: 6.14.0 Qt Version: 6.9.1 ADDITIONAL INFORMATION None.
Correction: Showing two identical devices does not require ”CD/DVD inserted when the system boots“ to occur.
For what it's worth, I can't reproduce this issue on my Fedora KDE 42 device that has a DVD drive.
