AMD Radeon HD 6470M dual monitor setup?

Mon Oct 24, 2011 3:32 pm

I would like to set up my laptop as dual monitor with a 20" monitor.

Here is my lspci:

$ lspci
00:00.0 Host bridge: Intel Corporation 2nd Generation Core Processor Family DRAM Controller (rev 09)
00:01.0 PCI bridge: Intel Corporation Xeon E3-1200/2nd Generation Core Processor Family PCI Express Root Port (rev 09)
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
00:16.0 Communication controller: Intel Corporation 6 Series/C200 Series Chipset Family MEI Controller #1 (rev 04)
00:1a.0 USB Controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #2 (rev 05)
00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 05)
00:1c.0 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 1 (rev b5)
00:1c.1 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 2 (rev b5)
00:1c.2 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 3 (rev b5)
00:1d.0 USB Controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #1 (rev 05)
00:1f.0 ISA bridge: Intel Corporation HM65 Express Chipset Family LPC Controller (rev 05)
00:1f.2 SATA controller: Intel Corporation 6 Series/C200 Series Chipset Family 6 port SATA AHCI Controller (rev 05)
00:1f.3 SMBus: Intel Corporation 6 Series/C200 Series Chipset Family SMBus Controller (rev 05)
01:00.0 VGA compatible controller: ATI Technologies Inc NI Seymour [AMD Radeon HD 6470M]
07:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 06)
0d:00.0 Network controller: Ralink corp. RT5390 [802.11 b/g/n 1T1R G-band PCI Express Single Chip]
13:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. RTS5116 PCI Express Card Reader (rev 01)

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 that monitor.

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 Smiley

Cheers

For me all it was needed was to set the relevant options in System Settings. And yes, VGA switching support in Linux is kind of poor at the moment.

Wed Nov 02, 2011 8:33 am Thank you I came across this yesterday and am still a bit wary: http://cisight.com/install-amd-radeon-hd-6470m-and-solve-overheat-on-ubuntu-1110-oneiric/ You can see my comments at the bottom. As of yet no one has responded. Feedback appreciated.
