Hello user, I have installed Debian wheezy today on my setup: Intel i5 2500k and HD 7870 but i'm having trouble to even start using it, At first i select debian to be booted instead of my windows 7. After that some error pop up and the main one is
"Radeon kernel modesetting for r600 or later requires firmware-linux-nonfree"
And i think that is causing me to crash at the desktop because as soon as i log in i have a blank desktop nothing but the wallpaper and after few seconds i get a crash saying something about recovery of the system.
I would like to inform you that im new to linux and i have no idea what i have to do, so if you guys tell me to do something try to explain it, like you would be explain it to a complete idiot. Sorry for any grammar mistakes or spelling, English is not my first language.

When the machine has finished booting and it crashed, press CTRL-ALT-F1. You'll see a login prompt. Login as root, using the root password you specified during install.

Then enter this command:
Look for a line:
The bold part is important. Ignore something else in http://http.us... It can be another URL.
The red part contrib non-free can be there or cannot be there. If it is not there, add it.
Save and close the file. Editing instruction are in the footer of the nano program.
You are now back in the command prompt.
Enter:
Once this is done, enter
reboot
It should be fixed now

Hello jilinkels, sorry for such a late replay but i had no time to test your solution. Today i have tested it everything went ok. Some how i manage to get on the system once and i restarted it to see if its fixed but nope, my system freezes after login in and i cant even access the cmd using ctrl+alt+f1 because even if i press that i freeze the system.

The error looks like this

I have googled it and its something about audio so i dont think this is causing my system to freeze when ever i press ctrl+alt+f1.
bug unable to handle kernel paging request at........
Cant give you the rest because there is more of that. I tried to using my phone to capture the image but its just too quick and my phone is bad. It took me 2 restars to look at the first line because you only have like a half of second to look at it. I only captured a bad image of it but it might help so i will give it here.Unless there is a way to access something like a log file then i can give you the whole thing. I have debian and debian rescue mode, so i still have my terminal on the rescue mode.

It is not very clear to me what happens. I can't open the images you sent.

Radeon HD 7870 is managed by either:
-the open source radeonsi open source driver on Linux. This is the one that comes preinstalled. Problem here is that this radeonsi driver is under development and wheezy has an older version of it. Additionally using this driver you need some other new components too (lvm/clang, mesa) + the X sever to work properly is restricted to the glamor acceleration method which isnt present at all in Wheezy. The Debian Testing/Unstable version has most of these components in place (still dunno about glamor, i have Testing and i have to compile it myself since its missing from the repos).
Installing latest versions of the open source driver is a bit of hassle, you have to compile various system components (mesa,llvm, clang, drm, glamor etc).

-the proprietary (still free) catalyst driver. This driver comes directly from AMD and should work out of the box. Now Wheezyy has old verrsions of this too, but the latest can be downloaded from AMD's site. This driver doesnt require other new system components. I recommend using this one on Wheezy, especially if you are new to Debian.

What do you mean you cant open the images? Well is there something like an error log file or something like that? that will let me see the error i've been getting.
Well how do i do that? Since im from windows my only way of installing is; "download-open-next,next-exit DONE" but this is linux so its different and the only way i can install it is using the rescue cmd ( because like i said before whenever i ctrl+alt+f1 my desktop freezes and i cant even get the norma desktop up) So if you wouldn't mind giving me the commands etc... i will be very greatfull.

Can anyone figure out how to solve this? i can provide any data that is needed if told how. Im guessing reinstalling linu doesn't help like it does on windows.

Rescue mode should be good enough to install the fglrx driver. How you do it is described in the Debian Wiki, start with that: https://wiki.debian.org/ATIProprietary
When choosing the correct driver for your card, go for the 12.6, not the 13.1 Legacy.

But what is in installtion part, Jlinkels has already told me to do that, and made it worse since i can only get to terminal in rescue mode, whenever i try to enter it with the shortcut ( since i dont have a proper desktop loaded ) it just freezes. What should i do now? Can you tell me how to get to log file ? Because before the login screen appears there is a error poping up for about 1 second, i cant even read the first line propely and there like 20 of them. The first line says something like that; bug unable to handle kernel paging request at. Im guessing im not going to be using this linux, can you guys recommend me any other linux version of debian or anything else for beginners ( Not ubuntu or backtrack none of them work too ). I know that backtrack wont work because of my setup configuration; hd 7870 and intel i5 2500k, so what ever you recommend would be nice if it would work on my setup.

@edit. i went on this site of AMD; http://support.amd.com/en-us/kb-arti...ler-Notes.aspx
To see how to installs the proprietary drivers as Gardin recommended, but it keeps on saying; 'navigate to the drivers you downloaded' and im guessing its saying downloaded as in going to the website and downloading it with GUI, but i cant do that since im not able to get to my desktop. Im probably missing something really easy to do, but im noob when it comes to linux

Navigate is context-sensitive. Since you are logged into a text only terminal, you will have to navigate in text mode giving the required commands. You have to know the full path of the downloaded file, and give the 'cd downloadedfilefolder' command using full paths for the folder where yu sownloaded your file.

BTW using Linux without the slightest knowledge of text mode commands will leave you frustrated. Go back to Windows or learn basic terminal usage.
