I recently upgraded my Dell Inspiron 5558 to Ubuntu 18.04. Ever since the upgrade, the DVD drive keeps opening automatically at random times. How do I resolve this issue?

Does Ubuntu 18.04 have the setcd
package available? If it is, install it and then run:
sudo setcd -s /dev/sr0
It should output something like this:
/dev/sr0:
Auto close tray: cleared
Auto open tray: cleared
Use O_NONBLOCK flag: set
Lock tray: set
Check CD type: cleared
If "Auto open tray" says "set" instead, running sudo setcd -o0 /dev/sr0
should fix your problem until the next reboot.
The root cause might be a tool in your desktop environment that can be used to mount removable disks. It polls the DVD drive every now and then. If the "Auto open tray" is set, the tray will open when the poll is done and the tool stops accessing the drive.
If disabling the "auto open" feature helps you, you might want to disable the "auto close" feature too, as it might try and close the drive just when you're about to place a disc on the tray. I had this problem with my system back in Debian 7 or so with KDE.
Ubuntu 18.04 has systemd
, so probably the best way to make these settings persistent is to create a service file to run the necessary setcd
command at boot time.
So, create a file in /etc/systemd/system
with a descriptive name and a .service
suffix. For example, let's call it /etc/systemd/system/dvd-stop-open.service
. The contents of the file should be:
[Unit]
Description=Disable DVD auto-open
Documentation=man:setcd(1)
[Service]
Type=oneshot
ExecStart=/usr/bin/setcd -o0 /dev/sr0
RemainAfterExit=yes
[Install]
WantedBy=multi-user.target
Once the service file is created, enable the service:
sudo systemctl enable dvd-stop-open.service
Test by starting the service and verifying that the Active:
field in service status says active (exited)
:
sudo systemctl start dvd-stop-open.service
systemctl status dvd-stop-open.service
Thanks, this seems to have solved the issue. How do I make these settings stick on boot? – Kunal Jagadish – 2018-07-27T04:40:00.117
