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.

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.
