Ubuntu

CD-ROM disappears

Asked by STR8ARO

OK, as near as I can tell:
- run from Live CD: cd-rom configured ok
- install to harddrive: cd-rom configured ok
- install updates (90) : cd-rom configured ok
- enable Desktop Effects - required Nvidia GeForce4 Ti4200 driver to be installed
   reboot
- cd-rom no longer available - Juicer can't find any CD-roms

lshw shows IDE harddrive, no cdrom
/etc/fstab appears same as when cd-rom works
    /dev/scd0 /media/cdrom0 udf, iso9660 user, noauto 0 0
dmesg shows no SCSI cd-rom
lsmod shows no cdrom or sr_mod
modprobe cdrom sr_mod results in:
FATAL: error inserting cdrom (/lib/modules/2.6.20-16-generic/kernel/drivers/cdrom/cdrom.ko): Operation not premitted

I'm new to Ubuntu, used to know enough AIX to be semi-dangerous - not a system admin.

How do I get back to a working cd-rom
(note: when it worked, while playing music cd it "paused" or "went quiet" every 5 secs or so for about 2 secs.)

Sigh, thanks for any help

Hello,

I don't know about your problem but the error you got when modprobing the module is because you need to have root privileges.
You should try with sudo:
sudo modprobe cdrom sr_mod

Yes, sudo modprobe worked better.
CD still skipped/paused when playing.

Installed openSUSE 10.2 that fixed it.
