Rootless X is owned by xuser, the problem is xuser doesn't have permissions to write usb storage when the type of filesystem is not one of ext2/3/4 or btrfs. ... mount /dev/sdb1 on /media/sdb1 type ext4 /dev/sdb2 on /media/sdb2 type vfat /dev/sdb3 on /media/sdb3 type ntfs /dev/sdb4 on /media/sdb4 type btrfs /dev/sdb2 on /media/sdb5 type jfs /dev/sdb1 on /media/sdb6 type xfs ... ls /media/ -al drwx------ 3 xuser xuser 1024 Apr 10 09:08 sdb1 drwxr-xr-x 2 root root 16384 Jan 1 1970 sdb2 drwx------ 1 root root 4096 Apr 10 09:12 sdb3 drwx------ 1 xuser xuser 0 Apr 10 09:14 sdb4 drwxr-xr-x 2 root root 6 Apr 10 09:39 sdb5 drwxr-xr-x 2 root root 256 Apr 10 09:39 sdb6 ... The usb storage is mounted to dir `/media/sd**' by a udev's mount.sh script, Modify the script to change the group owner of dir to `disk', and grant w/r/x permissions to it, so the one (such as xuser) in the disk group could access the storage. There are two solutions to do according to the type of USB's filesystem. 1, For vfat, fat, ntfs, add mount option `gid' and `umask'. 2, For others, invoke chgrp and chmod after mount.
