K3b CD/DVD刻录软件

Question

如何解决K3b的权限问题？

Answer 1

什么“权限问题”？我得猜一下。

您的userid是cdrom组的成员吗？

这些命令帮助了我：

walt@bat:~(16)$ ls -l /dev/cdrom
lrwxrwxrwx 1 root root 3 Sep 11 01:30 /dev/cdrom -> sr0
# /dev/cdrom is /dev/sr0 on my system               ^^^

walt@bat:~(0)$ ls -l /dev/sr0
brw-rw----+ 1 root cdrom 11, 0 Sep 11 01:30 /dev/sr0
# /dev/sr0 is a Block device Read-Writeable by user `root` and members of group `cdrom`

walt@bat:~(0)$ id
uid=1000(walt) gid=1000(walt) groups=1000(walt),4(adm),7(lp),20(dialout),27(sudo),101(systemd-journal),106(input),113(lpadmin),142(motion)
# I'm not in the `cdrom` group

walt@bat:~(0)$ sudo adduser $USER cdrom
[sudo] password for walt: 
Adding user `walt' to group `cdrom' ...
Adding user walt to group cdrom
Done.
# And now I AM a member of group `cdrom`, when I logout/login, or...

walt@bat:~(0)$ newgrp cdrom
# (starts a subshell with GID set)

+walt@bat:~(0)$ id
uid=1000(walt) gid=24(cdrom) groups=24(cdrom),4(adm),7(lp),20(dialout),27(sudo),101(systemd-journal),106(input),113(lpadmin),142(motion),1000(walt)
# I AM a member of the `cdrom` group

+walt@bat:~(0)$ exit
exit
# And now I'm not
walt@bat:~(0)$ id
uid=1000(walt) gid=1000(walt) groups=1000(walt),4(adm),7(lp),20(dialout),27(sudo),101(systemd-journal),106(input),113(lpadmin),142(motion)
