I bet it's the back button.
I usually get it by pushing the mouse left until it hits the screen border
Too bad this actually brings up the left bar on Ubuntu and it covers the button itself.
This actually requires to move the mouse again to clear the bar and then retry to center the button again.
Bad design decision.
Time to give Gnome 3 a try.
it may be stylish and minimalist, but do you think that your grandma could understand that she need to touch the circle and drag it around?
This is a geek oriented lockscreen, not one targeted at the mass market.
The iphone lockscreen is lightyears ahead:
I've seen children unlocking the phone the first time they've seen it without anyone telling them how.
I think Android needs an equally strong UI metaphor to appeal to a broad user base.
What can you use to convey the sliding action?
Take a look at this (badly) photoshopped (actually GIMPed) proof-of-concept:
I bet even the most techno-phobic can understand that he needs to pull and slide the zip.
Note: at the first try I've used the image of a zip from a blue jeans, but the risk of a two-way joke was too high, and that's not the spirit of this post.
Some time ago I added a second hard disk to my machine and I joined it to the root volume group. I've also created a logical volume with a /data filesystem on it.
Now I need to move that data disk to a new machine, but as long as it's part of the root volume group I can't easily move it without making the whole machine unbootable.
These are the steps on a Red Hat 5.4 machine:
First, make sure that the disk you want to migrate does not contains logical volumes that are spanned on other disks also: I checked it with the system-config-lvm GUI, that shows how logical volumes are mapped to physical volumes, and I saw that my logical volume lv_data was entirely on /dev/sdb.
This is the initial fstab with the /data mounted from VolGroup00
now split the root volume group creating a new VG_data
[root@testlvm /]# vgsplit VolGroup00 VG_data /dev/sdb New volume group "VG_data" successfully split from "VolGroup00"
you can see that the logical volume lv_data now belongs to the newly created volume group.
if you get an error, read at the bottom of this post.

But if one does not understand italian, what would he see? A string puppet? Or a man who's falling, but not because of the water on the floor: because he's beeing pulled from his feet with ropes.
In comics, the movement effect is done with lines that follow the subject in his motion, they don't trail it.
