To ATI or not to ATI

May 11, 2007 3 comments

I am planning on building a MythTV HTPC in July and I have started spec’ing components.

My requirements are as follows:

  1. Must use energy efficient components
  2. Must handle DVB-S and DVD-T
  3. Must output digitally (DVI & analogue audio or HDMI) in 1080p
  4. Must be capable of S3 suspend to memory and resume
  5. Must support Linux (obviously)

At first I thought this would be relatively easy. Most processors are energy efficient these days, so there is no problem there. Either a Core Duo or AM2 65nm EE should do the trick. 1GB of DDR2 and a 2.5” laptop hard-drive are also easy choices.

Graphics should be integrated on the motherboard to save a few extra watts and keep things cooler and should be Linux compatible… that should be easy… right? Wrong, Intel’s 965G chipset looks interesting, the 965G spec allows for integrated DVI, the drivers are fairly well supported by Linux out of the box, the GPU even handles MPEG2 and WMV decoding in hardware. The only problem is that there are no actual 965G ATX or m-ATX boards with DVI or HDMI, only VGA.

Next choice, AMD’s new 690 chipset looks interesting. I particularly like the MSI K9AGM2-FIH on Dabs.ie with integrated HDMI and VGA. The AMD690 chipset has lots of good value boards with HDMI and or DVI and or VGA. But the GPU is ATI and has all sorts of issues like not supporting XVideo and messing up S3 suspend and resume.

NVidia are not really an option at this stage because I have yet to find a board with integrated HDMI or DVI.

I know AMD marketing recently announced at the RedHat summit that they are going to improve their ATI drivers for Linux, but how much of this is fact? Their track record for keeping promises of that sort is not exactly very good.

Have I missed out on some other option? Should I wait until something better comes along? Or should I just buy the AMD690 board and hope for the best?

Dell Latitude X1 and FC4

December 22, 2005 1 comment

I got a new notebook a couple of days ago, a Dell Latitude X1. I have been using the “Traces of Martins State” site and blog which shares the experiences of an FC4 user in tweaking Linux for this laptop.

I’m using a fully updated FC4 build (as of 21 December 2005), and bios version A4.
So far, I have full video resolution 1280×768 working with Vesa. ( no DRI yet, it seems that my i915GM video card may not to be supported by http://dri.freedesktop.org/wiki/Intel?action=highlight&value=CategoryHardwareVendor yet – I’ll have to investigate more if Vesa prooves to be too much of a bottleneck for working with video.)

Getting full resolution to work was quite tricky. The card does not advertise it’s default 1280×768 resolution to software and so X has to be convinced that this resolution is possible using an application called 915Resolution

Wireless Lan seems to work using the instructions available here.

Everything else should work fine, except for the closed source Ricoh SD card reader. And the Modem (haevn’t tested these yet)

So far I am very happy with the X1, except for the battery – which only apparently lasts for about 1Hour & 40 Minutes – although I have yet to confirm this.
