Your password is probably for "sudo" operations, not for becoming root itself. Does root even have a password? (/etc/passwd, and /etc/shadow should tell you that). Debian, and I assume (perhaps rashly) Ubuntu, use group permissions for CD devices, so that /dev/hda (CDRW) here is; brw-rw---- 1 root cdrom 3, 0 2007-07-27 17:14 /dev/hda Read and write to group "cdrom" gets us CD access. Typically the permissions are set, or reset, at boot, and shouldn't be changed manually. You should just assign users to the relevant groups. As for why it happened. What changed? Someone fiddled ;) I'm unclear if you are dual booting, and if these are independent installed operating systems. If it affects two completely separate installs on the same computer, then it seems likely it is hardware, or bios. If the installs share something, even a home directory, all bets are off, since one or the other, may have done something the other doesn't like. Only way to resolve that is see if you can clear it, if a shared home directory, try a newer with no files, or possibly a live CD boot. -- The Mailing List for the Devon & Cornwall LUG http://mailman.dclug.org.uk/listinfo/list FAQ: http://www.dcglug.org.uk/linux_adm/list-faq.html
