the mouse does not hangs.

So its the problem with gnome-shell.

Bug reported on redhat bugzill is availiable at bugzilla.redhat.com.

So for those guys this is really an annoying thing, there is a temporary solution  .

Go to tty1 by pressing

Ctrl + Alt + F1

On successful login

pkill gnome-shell

Now go back to GUi by

Ubuntu 11.10

It seems like Ubuntu dropped Gnome shell and replaced it with Unity. Oneiric Ocelot will be shipped with Unity as default. But they say it will be much more improved.
Also heard a rumor that Fedora 16 will be shipped with unity.
Oneiric Ocelot will be powered using Linux Kernel 3.0 final
Other changes are improved application switcher, smoother compiz grid plugin and software center also got some improvements.

Gnome3 Customization | Change Panel Colour n Transparency

The default opaque panel on top of gnome3 is like eating milk n chala curry.
The /usr/share/gnome-shell/theme/panel-border.svg is the main file to be changed to change its appearance.

Now wake the gimp expert in you

open the file /usr/share/gnome-shell/theme/panel-border.svg in gimp

must be root to do it


sudo gimp /usr/share/gnome-shell/theme/panel-border.svg


modify the file as you wish


here i deleted the whole image

ctrl + a
Del


then took the brush tool choose colour black (default)

set Opacity to 52

made the brush image large enough to cover the full image

painted once in the image

then choose orange colour,

set Opacity to 100


painted a line in the bottom, this will appear as the bottom border.

saved it as

panel-border.png

because in gimp does not support saving a file in .svg format.
Also i don't know whether svg can handle alpha channel.

now the pic will look like as shown

Now open up the file /usr/share/gnome-shell/theme/gnome-shell.css


/usr/share/gnome-shell/theme/gnome-shell.css


goto the section

#panel {
    color: #ffffff;
    background-color: black;
    border-image: url("panel-border.png") 1;
    font-size: 8.5pt;
    height: 1.86em;
}


change the line border-image: url("panel-border.svg") 1;

to

border-image: url("panel-border.png") 1;

save the file

reload the gnome3 desktop by hitting

Alt+F2

then enter

r

hit Enter

Gnome3 Customization | Change Alt+Tab color

To change the color or transparency of Alt+tab App switcher in Gnome 3, you need to edit the file "/usr/share/gnome-shell/theme/gnome-sll.css"
You can do much if you know css basics.




Open the file

sudo gedit /usr/share/gnome-shell/theme/gnome-sll.css


go to the section

.switcher-list

use search to find it (ctrl + f)

the line

background: rgba(R,G,B,A);


The R,G,B for rgb values of the colour
Change it by referring here

A stands for alpha channel. use a value from  0.0 to 1.0
0 is transparent.

example :

.switcher-list {
    background: rgba(173,255,47,0.5);
    border: 1px solid brown;
    border-radius: 24px;
    padding: 20px;

    font-size: 9pt;
    color: brown;
}

In the example above i have changed the border colour to brown.

open the file in gedit or any text editor you like
