GPU Compatibility List

The purpose behind this page is to give a compatibility probability list for unsupported chipsets, and to confirm these when possible.

-- All GPU's listed here are considered UNSUPPORTED -- though this matrix seeks to give you solutions we will not automate, but have figured out as workarounds. All GPU's not listed here are currently believed to be supported. If not please notify L3mce preferably in IRC, or at the forum.

Some common information you will want to get and use. Please give this data when creating a ticket or forum post about a card not working/not listed here.

• Begin any of this sort of work as root. All commands in this matrix assume you are root. If you have ssh'ed into your MD, you are already root. If you are on a hybrid then:

sudo -i

• Update PCI IDs

update-pciids

• Detailed card information

lspci -nn | grep -w 'VGA'

• Card PCI ID

lspci -nn | grep -w 'VGA' | sed 's/.*://;s/\].*//'

• Audio cards that ALSA can see

aplay -l

• Look at ALSA config file

cat /etc/asound.conf

• Look at xine config file

tail -4 /etc/pluto/xine.conf

• Check ALSA version

apt-cache policy alsa-base | grep Installed

• Check ALSA backports installation status

apt-cache policy linux-backports-modules-alsa-$(uname -r) | grep Installed

All together, minus rooting:

update-pciids
lspci -nn | grep -w 'VGA'
lspci -nn | grep -w 'VGA' | sed 's/.*://;s/\].*//'
aplay -l
cat /etc/asound.conf
tail -4 /etc/pluto/xine.conf
apt-cache policy alsa-base | grep Installed
apt-cache policy linux-backports-modules-alsa-$(uname -r) | grep Installed

Audio: For the terms of this list, "audio" refers to digital audio from the card, typically HDMI audio. For further understanding of how audio currently works, please see the new audio scheme for possible resolution of audio issues without installing things you do not need. If your cards audio device shows up in aplay then nothing more is required to install, only a configuration change is necessary, as detailed in the link.

nVidia

Intel

ATI

dpkg

Should any of the solutions below throw back dpkg errors then:

dpkg --configure -a

A working system should NOT produce any result. If it DOES produce output, then it has tried to fix itself. Try commands again. If there are STILL problems, you need further assistance to stabilize your system.

MythTV

Some of these configurations cause MythTV to not utilize !default correctly... so in the MythTV front-end (NOT backend) setup/general, you may need to specify HDMI or plughw:1,7 (example assumes you are on card 1, device 7) from the detected options available in the audio setup. In some rare cases with ATI or Intel you may find it necessary to drop the device number... so turn its auto-detected "plughw:1,7" into "plughw:1". I recommend using a keyboard with a delete key, because in myth, backpsace takes you back a menu.

To get to MythTV general setup, open MythTV, once it finishes tuning a channel, press escape. Don't do it to quick or myth will think it died and try to respawn. This will take you your recorded programs most likely. Press esc. Choose Setup. Choose General. Audio is on the second page as memory serves. Left and right in the Audio field will scroll through the options.

Solutions

All solutions here can be copied/pasted, but assume you are root. Please begin sessions by typing "sudo -i" without quotes and enter your pass when prompted. It is recommended that you reboot after any of these solutions. /usr/pluto/bin/RebootWithAVWizard.sh is probably best for testing after applying solutions.

Add Intel Advanced Support

apt-add-repository ppa:kernel-ppa/ppa
apt-add-repository ppa:glasen/intel-driver
# For additional performance issues, the following may help
# apt-add-repository ppa:f-hackenberger/x220-intel-mesa
apt-get update

Add nVidia Current Driver Support

With the 304+ nvidia driver we recommend pulling down alsa .25 at the same time as prescribed here.

/usr/pluto/bin/Stop_X.sh
add-apt-repository ppa:ubuntu-x-swat/x-updates
apt-get update
apt-get install -y nvidia-current

Add ATI Catalyst Support

/usr/pluto/bin/Stop_X.sh
wget -P /tmp http://www2.ati.com/drivers/linux/amd-driver-installer-catalyst-12.10-x86.x86_64.zip
apt-get install unzip
unzip /tmp/amd-driver-installer-catalyst-12.10-x86.x86_64.zip ~/
sh ~/amd-driver-installer-catalyst-12.10-x86.x86_64.run

Then follow the instructions.

Add ALSA Backport .24 Support

apt-get install -yf linux-backports-modules-alsa-$(uname -r)

Add ALSA .24 Support

add-apt-repository ppa:team-iquik/alsa
apt-get update
apt-get install -y alsa-base
apt-get install -y alsa-utils

Speaker Test

NOTE: This command sequence requires the user set the cParam and dParam values

Where cParam=<your card #> and dParam=<your device #>. For the standard discovery need, these will be revealed by:

aplay -l | grep -i hdmi

nVidia GT chipsets reveal device numbers 3, 7, 8, and 9. Almost all of them are device 7. If you see the devices in aplay and you do not have audio, test each until you get signal.

cParam=
dParam=

if [[ -n "$cParam" ]] && [[ -n "$dParam" ]]; then
. /usr/pluto/bin/Utils.sh; if [[ "$AlternateSC" -ge "1" ]]; then 
speaker-test -c2 -l1 -t sine -Dplughw:${cParam},${dParam}
else 
speaker-test -c2 -l1 -t sine -Dplughw:${cParam}
fi
else StatusMessage "You must set the variables for both cParam and dParam. They cannot equal null"
fi

Upgrade Kernel to Natty

CurKernel="-generic"
if uname -r | grep "pae"; then CurKernel="-generic-pae"; fi
NewKernel="linux-image${CurKernel}-lts-backport-natty"
NewHeaders="linux-headers${CurKernel}-lts-backport-natty"
apt-get -yf install "$NewKernel"
apt-get -yf install "$NewHeaders"
apt-get update
apt-get -yf dist-upgrade

Upgrade Kernel to Latest Oneiric

CurKernel="-generic"
if uname -r | grep "pae"; then CurKernel="-generic-pae"; fi
NewKernel="linux-image-3.0.0-26${CurKernel}"
NewHeaders="linux-headers-3.0.0-26${CurKernel}"
apt-get -yf install "$NewKernel"
apt-get -yf install "$NewHeaders"
apt-get update
apt-get -yf dist-upgrade

Solutions to Supported GPU's that are not working

Due to some bugs, things which work for just about everyone do not work for a few oddballs

nVidia

GT series (including ions)

=Nothing in aplay

• Confirm aplay -l is being run as root.
• Run the list of commands here and see that backports AND alsa-base .24 are not both installed.

No audio:

• Use speaker-test to determine which, if any, will make noise, using the output of aplay -l to assign the correct card number.
• Change line 225 of SetupAudioVideo.sh CardDevice from 7 to X where X is the device number you could hear.
