(12.10) Radeon HD 7850 & Intel HD 4000

[shouthouse]

I'm having quite the rough time figuring out how to install my graphics drivers correctly. Ubuntu runs fine off of the integrated 4000, however I do not have a screen that has vga. I need to use the mini displayport from the Radeon HD 7850. (I have to use my girlfriend's screen while setting ubuntu up which means she can't use her computer)

I have tried many things including http://askubuntu.com/questions/20511.../210565#210565


However when I got to the first reboot in those directions ubuntu would only boot into low graphics mode and would stop recognizing my input devices. Thus I am stuck. Spent about 8 hours yesterday screwing around with all of the different ways I could.



ASRock Z77 Pro4-m
Intel i5 3570k w/ integrated HD 4000
MSI Radeon HD 7850 2gb
8 gb Corsair Vengeance 1600 MHz

I don't have dual graphics cards, but this thread seems to fit your setup quite well:

Wow thanks I am going to try that out. I hope I am able to get to the terminal to purge. I gave up last night when it went wonky on me again. I am anxious to figure this out. I rather enjoy Linux except for I'm a noob so I get frustrated.

Reading through this it seems that it should not work. At the end of the thread it explains that it isn't working on a 7570 or most setups, and that it is for 12.04.

I again got to the reboot and it is saying that it cannot properly detect the settings. Ugh... hmmm I am so curious... Tomorrow I may uninstall and try again from a clean untainted system.


EDIT: Anyone know what I may be doing wrong?
Ugh I really have no idea. Starting over agaaaain.

Is there anything I may be able to do from UEFI to force the computer to only use discrete card upon boot?



Definitely does not work. Complete bummer.

there is a workaround to just use intel driver, http://techhamlet.com/2012/05/ubuntu...able-graphics/
I have the same problem i guess, a lot of people do- there is a bug that may apply https://bugs.launchpad.net/fglrx/+bug/1068661, read it carefully, as there is a bit of a mix between this kind of bug, and people needing the legacy drivers for radeon 4000 and other earlier ones... When stuck at low graphics mode purge all fglrx* this should get you back to your home screen. My problem then was overheating comp, and poor battery. So i switched to sandybridge for my intel card.

As far as i can see on AMD's site my card isnt suported by thier proprietary drivers, you might want to check.
