I can set up dual monitor and my monitor size, placement etc in sys settings, but when I want to add a panel or widget to my 20" monitor video dies on my.

Since I am still using the default driver and have never done this i would like some aid.

1) Do I use "additional drivers" to install the prop ati driver or do I take this route:

2) There also seems to be a problem with swithchable graphics:

Which I am not sure I understand. How do I know which graphic card is being used when?

Also I read that my card will go "up to" 1GB RAM. I know it is a dedicated card, but how can I find out how much RAM my card has.
There is nothing in the BIOS which gives my any info.

I tried installing prop drivers once on my older machine and it was a BPOS, so I would like to get my facts straight first

Cheers

No one?

Re: AMD Radeon HD 6470M dual monitor setup?

well under non switchable gfx you would use 'kdesudo amdcccle' and set it up in the drivers config program . if you have tried that then the process might be slightly different for swichable gfx. reading the second link it says not to use the ati driver....

i know thats not very helpful but its all i've got on this one.

Thanks for the response, but you are right. It is not really helpful, just a bit more confusing.
