Install AMD and NVIDIA graphics on same os ?

[kdeuser]

Hello,

I want to add an extra graphics card to my os (an nvidia ) , as this has hardware acceleration and mkv videos would smooth out.

Gone through so many installs that a couple more would n`t hurt.

Keep getting errors though :

Reelbox login : dyndnsd: dyndns turned of in
* Doing sanity -checks (startup)
* Checking Battery
......lots of other gibberish followed by :

nx sensor is disabled in `/usr/Nx/etc/made -cfy`
*EAnabling additional executable binary formats bin fnt-support
Trying to start Nx servers
Nx>122 service started
Nx>999 Bye
Trying to start Nx statistics :
Nx>723 Cannot start Nx statistics
Nx>709 Nx statistics are disabled for this server
Nx>Bye

Reelbox Login : Cat: /tmp/vdr.wakeup: No such file or directory
Setting Reelbox Frontpanel LEDs (startup)

login screen and repeating over again.

More konsole output :

ata 5 status : (dry ERR)
ata 5 status : (DNC)
ata 5 exception Emask 0x0 Suct 0x1 SErr 0x0 action 0x0
ata 5 cmd 60

So with both cards in place i boot up , let the os go through it`s motions and just when it seems as though the splash screen is about to appear the screen goes black with a prompt for login.

Does n`t end there , a few seconds later and the above text in code displays.

Help much appreciated - thanks.

Sounds like a Mission Impossible.

At startup the system needs to decide what video driver to use to paint the screen, in this case it'll result in confusion.

There is one exemption I know of, it is a combination of an Intel chip on the MB for simple stuff plus an additional nVidia card for the heavy lifting
The system is known as Optimus and for Linux there is the Bumblebee project to make this possible.

What you want is not covered and I don't think it'll ever will.

Sounds like a Mission Impossible.

Installed the nvidia driver in the end and running separate to amd but no audio ( on both ).

Loaded in some updated sound drivers from another forum and this solved it - partially .

I now have a hard drive with no mount point , so it won `t mount .

On top of that i can`t write to my other drives ( not so good )

I will start a new topic on the drives.

Thanks to every one that helped.
