  1. Slak 12 does not see CD/DVD drives

    Installed Slack 12 on a test 40GB drive this afternoon. Very slick. One
    tiny problem:
    it does not see my two CD/DVD RW drives (hdc and hdd). When I try to
    access them or
    mount via KwikDisk, I get a panel saying I do not have
    rights/permissions to open these
    items etc.

    Any Ideas?

    Read the thread Alt.OS.Linux.Slackware FAQ pointer, you'll find that
    whilst I had the same problem there was a solution.

    OK - what you seem to be saying (FAQ) is that Slack 12 has some
    libraries missing
    from the distribution. Not quite ready for prime time are we? For the
    nonce, I'll stick
    to Slack 10.2.

    Not quite, for some reason when I installed the installation system
    wouldn't accept kdeedulibs-3.5.7, in order ot ge them in I had first to
    sort out how and what HAL did, which with the guidance fo Robby
    Workman's excellent advice I did. Having done so, I could then read the
    CD and install using pkgtool the missing lib.

    I did whilst I installed and used 11.0, however as 12 seems so much an
    improvement I'll put that, (12.0), onto the partition on the other disk
    where 10.2 is.

    AN UPDATE: - problem appears to be not missing libraries but just a
    simple comment "out" of
    the /dev/cdrom line in /etc/fstab. Removed the "#" , rebooted, and voila
    - the cd/dvd drive
    is recognized. We go forward. Thanks for your help.

    I don't think that you've got that quite right, put the # back where it
    was, and add the user to the appropriate part of /etc/groups. Do what I
    did, re-read the advice from Robby Workman again.

    Although it may be that you have got it right, and I have got it wrong,
    but it all seems to be working for me, and I can't believe that the
    maintainer would have commented out part of the fstab without good
    reason.

    Works for me. At this point, it is the fix of my choice - i.e. least
    effort.
    I spent half a lifetime scrutinizing code for mistakes. Now that I am
    retired
    and am not getting paid for it, the least effort method is the one I go to.
    Try it. You and Workman may have it wrong.

    Thanks again.

    I guess there's more ways to skin a cat. I cant get Robby Workman's
    method working so I have to have an entry in /etc/fstab for the
    devices.

    One thing is that you have to set the owner in fstab to "user" or else
    the users cant mount the devises.

    From what I remember that was always the way I did it, I used the
    example from that excellent resource 'Userlocal'
    http://www.userlocal.com/tips/usermounting.php for several versions.

    In fact it was mRgOBLIN's printing article that I also used to run
    printing in Slackware, I could never remember how I'd set it up last
    time when the next version came out so I'd turn to 'Userlocal' with
    each new version. Its just that Robby Workman's way of making devices
    work for users was on this newsgroup, perhaps 'Userlocal' should get
    him to let them put it in with all their other useful stuff, and maybe
    it could also be a contribution to the FAQ.

    For another reason I rebooted the computer and now it works like its
    supposed to without the entry in /etc/fstab

    I hate it when **** like this happens. I'm a slacker and I'm supposed to
    be in control! But f?cking no.

    Almost certainly due to the fact that the messagebus service had not
    been restarted. Rebooting, of course, fixes that :-)

    Maybe, but I thought that '/etc/rc.d/rc.messagebus reload' would fix
    that. But HAL is something completely new to me. so I could be wrong-

    I'm coming into this discussion fairly late (still catching up; you guys
    were busy while I was on vacation!), but (and perhaps it's just me) I
    was under the impression that HAL and DBUS and the rest of these things
    were supposed to make it *easier* to use removable devices. It looks to
    me (though I've not yet seen Slackware-12.0) as though it has been made
    more complicated.

    They (the kernel and "rest of the system" developpers) had something
    that worked just fine: add a line to fstab with appropriate options and
    ordinary users would be able to mount removable disks. Now they've gone
    and broken that so the kernel can mount the disks for you???

    >

    I think the thread titled "what does HAL do?" (or whatever the exact
    wording was) seemed apt, not the thread but the question, because
    Slackware 12 is the first I've heard of it. I looked it up, and
    the "d-bus" too, but I haven't really studied what I searched for,
    so I still only have a basic idea of it all. Before we can really
    make it work, we've got to figure out what its purpose is.

    When I installed Slack 12 on Monday, I simply told the install to
    not start the two relevant daemons. It seemed to be the simplest
    solution, not that I've gotten far enough to play with it but just
    given the posts and the lack of clarity about its purpose. I can
    always turn them on later.

    I basically haven't done anything with the install, it's on a different
    partition, so I can't say whether or not things work with the daemons
    off, like they used to, or if there is some other problem.

    We don't have to adapt it, unless something else has had to be
    adjusted to compensate. I don't use a GUI that much, and the introduction
    seems to be for the GUI-users. One thing I did catch from the quick
    glance is that some later version of KDE will depend on it.

    Nothing is broken in that regard. If you prefer the old behavior, it
    still works exactly like it used to work; you don't even have to disable
    HAL, contrary to what a lot of whiners have posted in various places.

    In fact, you can get the best of both worlds if you want. You can add
    lines to fstab with appropriate options and ordinary users can mount
    removable disks -- either via HAL/DBUS or the "old" way. It all hinges
    on "appropriate options" - it seems that many people "forgot" that
    the default option of "owner" on /dev/cdrom does *NOT* allow normal
    users to mount it, so this happens:
    1. Uncomment /dev/cdrom line in /etc/fstab
    2. Try to mount it from command line - permission denied
    3. Try to mount it via DBUS/HAL - permission denied
    4. Whine
    5. Blame HAL/DBUS for all that is wrong in the world
    6. Whine

    Hope that helps :-)

    Yes, I've been finding that, having finally installed Slackware-12.0 on
    a couple of laptops. I'm still working on getting these "fully
    configured" but they're certainly in a usable state, and work quite well
    (one is low on disk space for some things I want to do, but that's not
    Slackware's fault).

    Yes, I see. In my case, at this point, I've opted for a slightly
    different approach than any that I've seen discussed so far: I modified
    /etc/dbus-1/system.d/hal.conf as follows to permit any human users to be
    able to mount and unmount pluggable devices (and removable disks) via
    HAL/DBUS, so far without any difficulty:

    --- /etc/dbus-1/system.d/hal.conf.original ...
    +++ /etc/dbus-1/system.d/hal.conf ...
    @@ -66,8 +66,8 @@



    -
    -
    +
    +





    Basically my intention was to permit mounting of devices without needing
    to always remember to add new users to the "plugdev" group: all human
    users (and only the human users) on my systems are in the "users" group
    by default. The group file is cleaner, and in the long run this
    achieves the result with the least amount of work. Granted, I feel it's
    still too soon to know whether I've broken anything by this, but I've
    tested with two different types of USB storage devices (one a flash
    "disk" and the other a portable hard-drive) and some CDs without any
    trouble. In fact, I find it works quite well.

    My fstab on this system has no mention of any of the removable devices.

    I'd be interested in knowing if anyone is aware of any caveats I should
    consider regarding this approach, of course ...

    Nothing at all wrong with this approach. In fact, this is exactly how
    I configured HAL in the first build that went on SlackBuilds.org, and
    I *think* there is/was a note in the README about editing the hal.conf
    file this way if that behavior is desired. In short, that's a perfectly
    valid configuration, and for some purposes (including yours), it's by far
    the easiest way to do it.
