Linux – Access Desktop as root user in linux

iso-imagelinuxmountroot

I know the command to get to your Desktop is cd ~/Desktop. This however does not work as the root user. However I need to be the root user because I would like to move a file, from my desktop into my /mnt/disk folder so that I can mount my .iso. I can't click-and-drag either as I do not have permission. I've been trying for about an hour and am quite frustrated; so any and all help would be much appreciated. Thank you.

If you want to access a folder under another users home directory instead of using ~ you need to use ~username. So I would do something like ~zoredache/Desktop. You could also simply use the full path. Typically on a Linux system the home directories are under /home, so you could use cd /home/zoredache/Desktop.

If you cannot access your home directory while logged in as root, then that indicates that you may be try to access a filesystem that was mounted with fuse. As a security measure, by default, fuse will setup restrictions to prevent any else from accessing the filesystem except the user that mounted it.

Linux – Mounting ext4 drive with specified user permission

Use bindfs:

A FUSE filesystem for mirroring the contents of a directory to another directory. Additionally, one can change the permissions of files in the mirrored directory.

Mount the ext4 filesystem as /media/disk:

sudo mount -o user /dev/sdXN /media/disk

Bind the mounted filesystem with permissions for the current user (or any other user/group):

sudo bindfs -u $(id -u) -g $(id -g) /media/disk /home/user/new_disk

Linux – Debian disable su to root user

auth sufficient pam_rootok.so
auth sufficient pam_succeed_if.so use_uid user = privileged
auth requisite  pam_succeed_if.so uid > 0
auth requisite  pam_unix.so

You could do this with sudo in an easier way:

privileged    ALL=(ALL:ALL) ALL
public        ALL=(privileged) ALL
