    Question Not authorized...

    I used the USB installation of Knoppix 7.6.1 for a while with great success and decided to Install this version on HD.from the Live DVD. I used "KNOPPIX HD Install" as offered in the menu.
    All went well and smooth. Right now I'm struggling with two minor issues:
    1) On the top of the screen I have a taskbar/panel or the like, with no reaction to
    mouse clicks. See attachment "Quasi taskbar"
    2) I have no access to other partitions. Using the PCMamFile manager or dolphin.
    When trying to mount a partition with either NTSF or ext3,4 file systems on it, I get the message: Not authorized to perform operation.See attachment "NotAuthorized"

    I appreciate any response, help, solution...


    PS.: I was not able to figure out how to attach the screenshots...?
    Why am I not allowed to...?

    Just some additional remarks to this issue: I thought it has to do with the ownership of the partition I want to access but it isn't the case. On the USB install and on the HD install the ownership of /media is root and the ownership of the content of /media is knoppix. From the USB install I have absolute no difficulties to access the partitions of my other systems (Ubuntu, LM, WINDOWS)

    More additional Info concerning the mystery taskbar/panel: I randomly selected the 5045485-knoppix-wallpaper.png, which is most likely a full desktop screenshot and should not be used as wallpaper at all. So this is solved and I'm going to delete this part 1) from the original thread.

    Check if /etc/fstab is corrupted and fix it.

    Thanks for the response, Joselb, I checked /etc/fstab of the USB-installation and compared it with /etc/fstab of the HD installation and I did not find a difference except the line for sdc1 which is the HD partition where Knoppix is installed. The difference is only that /dev/sdc1 is / and not /media/sdc1.
    This is the fstab of the HD install.

    PHP Code:

    I'm not knowledgeable enough to figure out what could be wrong. Could you please help?.

    Additional info:
    When I use the terminal and mount the partitions with:
    knoppix@Microknoppix:~$ su
    root@Microknoppix:/home/knoppix# mount /media/sda7
    root@Microknoppix:/home/knoppix# mount /media/sdb5
    root@Microknoppix:/home/knoppix#
    then I have access, although, if I want to unmount from the File Manager (e.g. Dolphin) I get the same message - Not authorized to perform operation.

    I have never installed knoppix in hd, in fact it's a very bad idea (you should install another gnu/linux system like ubuntu, linux mint, etc).But I think that installing it it's very possible the owner and group permissions have changed. Check in terminal with ls -l /media/*

    I suppose that the Live DVD and the USB install both have some kind of -root privileges-
    to manage directories, folders and files and these privelidges are not given in HD installation.

    Yes, I think so.

    I figured out that the file systems of the hard drives sda and sdb are not detected after boot.
    Could this be the reason for not being able to mount?
