[SLUG] CD/DVD drive icon disappeared

[Richard Lung]

To Linux members,

A K3B CD/DVD burn icon has appeared on my desktop and works - for burning, but 
the CD/DVD icon now wont appear on my desktop when I put a DVD in the drive. 
So, I can burn CDs from existing files on the hard-drive or from the floppy 
drive, but I cannot play or copy CDs or DVDs on my PC now. 

The totem video player from the menu cannot play.

Is there an untechnical way to get back the CD/DVD play and copy icon, please?
A wimp, I have no knowledge of command lines and wouldnt trust myself with 
lines of code, because there are liable to be too many snags, any one of 
which can make things worse than they were before. You have to know what you 
are doing, and I dont.

Recently, I lost boot-up. (There was a "capable but disabled" message.)

As usual, the CD/DVD drive wouldnt open, on pressing its button, to put in the 
OS CDs. 

(That could only be done from right mouse menu when desktop was available. --- 
Tho, the CD drive does open now by pressing its button now.)

So, I went into the boot menu F11, and arrow keyed down for the PC to 
boot up from the CD drive instead of the floppy. ( I dont have a boot-up 
floppy disk.)
But on not being able to boot up again, when I tried F11 again, the CD-drive 
option was missing: two options instead of three. (I selected the other option 
to the floppy drive, presumably the hard drive.) Hence, when I subsequently 
mounted a CD, the non-appearance of CD drive icon, I suppose.

The computer wouldnt turn itself off but instead of pulling the plug, I 
pressed the CD drive button. Its light went on, the PC turned itself off. And 
next time, the boot-up went on from lighting up the floppy drive to lighting 
up the CD drive, and without much trouble, the PC has booted up alright ever 
since! Absurd but true, otherwise I was really stuck - not having your 
specialist Linux help!
And I dont want to mess with the system, in a way that might put me back to 
losing boot-up, even tho I need the CD drive.

Richard.
