Dell inspiron 5520

Something is wrong here. The OS partition CANNOT BE 3GB. Ubuntu needs at LEAST 5GB just for the installation procedure.

Also I cannot understand this problem with.. "bottons" and the "lighting" and the "x value". Please describe better
or upload a picture - screenshot (if you have).

You can upload screenshots here only if you upload the screenshot to a free image hosting site (eg imgur.com) and then post here the Direct Link.

can i extract the Dell added settings and inject them to 12.04 source and place that source on the sda2 ? (4)
is there an ubuntu 12.04 for inspiron 5520 , which made for the same laptop but new version which i can replace the one on sda2 drilectly with out the need to extract the models and modify a source . (5)

about the 3 bottons i have uploaded a video for them , and i dont know how but they worked again ,
i dont understant , i think those botton lighting view has nothing to do with the OS installed . am i right ?
i dont know what could case that functionality error.
the last botton i pressed is the one that print the value " x " (just the x ) and not on all place , i can use it on notepad while i can't on websites ,
what is the differant between that x and the letter x (6)
what should these letter do on a windows . (7)
here is the video

now after i made upgrade , and the intel driver deletion , how to know if there are more removed Dell models or setting that changed , (8)

the ubuntu sound setting can increase the volume up to 150% or so . i am afraid if the upgrade changed the sound setting which could affect my speakers . (9)

i can't find any power options , how to know the configration that i am using and if there are more profiles .
is those profiles customized by Dell ? (10)

It seems you don't have the Vanilla Ubuntu environment (Unity) but gnome-shell instead. Which version of gnome-shell you have ? 3.4 ?

Ubuntu 12.04 considered as the most stable version of Ubuntu. You can try to install Ubuntu 12.04 from scratch with the vanilla desktop environment (Unity) and see if works ok.

Most of drivers are pre-isntalled, if you need help with wireless of/and graphics card drivers we are here to help.

Download Ubuntu 12.04 from here
http://releases.ubuntu.com/precise/

burn the .iso image to a DVD or USB, then boot from there and install Ubuntu from scratch. Install Ubuntu 12.04 upon 11.10.

If you made an update - release upgrade then maybe something could be wrong. Sometimes this happen.

Retry with an install from scratch.

Is the issue the LEDs on the keyboard? Just to clarify.
