Could anyone suggest me what should I do?
The problem is:
When I attach usb device or insert CD or DVD disc, I get warning(see attachment)
with this text
Unable to mount "KAM":
Rejected send message, 1 matched rules; type="method_call", sender=":1.44" (uid=1000 pid=25577 comm="exo-mount) interface="org.freedesktop.Hal.Device.Volume" member="Mount" error name="(unset)" requested_reply=0 destination="org.freedesktop.Hal" (uid=0 pid=1770 comm="/usr/sbin/hald))
I can mount any device successfully as a root
So the problem must be I don't have enough rights
I added myself to cdrom group with: usermod -a -G cdrom "username"
and looked in /etc/group
There is a line: cdrom:x:19:"username"
so it seems everything should work, but it doesn't, what would be your advices?
