What's the contents of 70-persistent-cd.rules? I recently had the same |
| 15 |
problem on a HP laptop; the DVD drive worked in most things, but not in |
| 16 |
K3B, and I tracked the root down to the fact that while I could see |
| 17 |
/dev/sr0, the symlinks for /dev/[cdrom,cdrw,dvd,dvdrw] weren't there. I |
| 18 |
could mount /dev/sr0 and the drive worked, but K3B never found the |
| 19 |
drive. I believe I fixed it by editing that rules file somehow. I |
| 20 |
can't remember while laptop it was on, but here's the two |
| 21 |
70-persistent-cd.rules files I have: |

(I think this one was the one that worked) |
