HP Pavilion dm1 (E-450/HD 6320) and Ubuntu 11.10

Wireless (BMC4313) Drivers:

There seems to be some issues with the current range of broadcom drivers, there are several options and some barely work and give very poor wireless signal and flaky connections.

Check you wireless card
lspci | grep Broadcom

Output:

03:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01)
Installation:

There are two options here:

Option 1

You should also be able to use the drivers in Additional Drivers, the “Broadcom STA proprietary wireless driver”, however before doing this you need to run these commands to install the required headers and tools as it seems this step was missed out:

sudo apt-get install build-essential linux-headers-generic
sudo apt-get build-dep linux

To check to see if you have this directory do this:

ls /lib/modules/`uname -r`/build

Now go to Settings > Additional Drivers and simply click install on the “Broadcom STA proprietary wireless driver”, reboot and you should experience much better wireless signal and connection stability.

Option 2

If this doesn’t work for you un-install those drivers and download the source drivers and build them from source and this works well, these can be found here: http://www.broadcom.com/support/802.11/linux_sta.php.

 


Graphics (HD 6320) Drivers:
Installation:

These can be found in Settings > Additional Drivers.

Install and reboot.

NOTE: This driver doesn’t account for sound over HDMI, the sound will continue to come out of the speakers. I’m looking in to a fix for this.

Fixing the “AMD Ubsupported hardware” Watermark:

You’ll probably now notice a watermark at the bottom right hand of the screen, reading “AMD Ubsupported hardware”. While the drivers are working away, they seem to think it’s unsupported. You can either remove the propriotry drivers and use the open source version. Or you can run the following script (found here) to remove it:

[gist][/gist]

To run, either right click and save as on the link to “view raw” or copy and paste in to a file and save the file as “fixwatermark.sh”

Make executable:

chmod +x fixwatermark.sh

Run:

sudo ./fixwatermark.sh

(Thanks to Andy pointing out in his comment, this needs to be run as root (I’ve added the sudo above).
Reboot your system and the driver will still be running but the watermark will be removed.

    Many thanks for this – my new Toshiba Satellite Pro C660D-1CE (catchy name) has the same graphics chipset and the same “Unsupported Hardware” watermark issue.

    Just a quick heads-up to anyone else who reads this; you do need to run the fixwatermark.sh as root (in a terminal, sudo ./fixwatermark.sh) or it’ll just throw a bunch of permissions errors.
