Is there anymore builds with Nvidia Legacy drivers at all? Anywhere?
Did I do something wrong when I used Minimyth.conf.mk like this?
Some info: I used Ubuntu 10.10 x86_64 with Intel Core 2 Duo T7200 and 2 GB of ram on ext4 filesystem but don't know if this is interesting. Target machine is running 1 GHz VIA C3 with 320 MB of memory and it boots of 4 GB (too big, but that shouldn't harm) CF-card. I also tried with another machine that is virtually allways power on, just because I don't want to keep my laptop running all night long. It has Ubuntu 10.04 LTS i686, AMD Sempron 2 GHz and 512 MB of mem and it's using ext3 as FS. In both cases all prerequisites should be fine. Gar files I took from here: http://www.minimyth.org/download/stable/latest-0.23/ a few days ago.
I am reading correctly from here

This should support your card, which you have done
Code: Select all
# Valid values are '96.43.19' (legacy), '173.14.28' (legacy), '260.19.29'. mm_NVIDIA_VERSION ?= 96.43.19
Maybe below can help you create a xorg, telnet to your frontend and see what you can do.
Last option.... a cheap card $35? Is it worth the hastle trying to make it work?
Hope this helps.

Linux Display Driver - x86
Version: 96.43.19 Certified
Release Date: 2010.11.16
Operating System: Linux
Language: English (U.S.)
File Size: 15.7 MB
* Added support for X.Org xserver 1.9.
* Added support for X.Org xserver 1.8.
* Updated nvidia-installer to detect the nouveau kernel module and fail with an appropriate error message.
Note to SuSE users: please read the SuSE NVIDIA Installer HOWTO before downloading the driver.
Installation instructions: Once you have downloaded the driver, type " sh NVIDIA-Linux-x86-96.43.19.pkg1.run" to install the driver. NVIDIA now provides a utility to assist you with configuration of your X server configuration file. See the README or run 'man nvidia-xconfig' for details on usage and instructions for those wishing to edit their X config file by hand.

Well, my whole Mythtvfrontendboxthingproject is all about those things. Cheap and work to make it cheap. I don't think there is much sense to pair VIA C3 1GHz with something like GeForce 8400 AGP.jamesarbrown wrote:Last option.... a cheap card $35? Is it worth the hastle trying to make it work?
Edit: Checked prices and the cheapest one was about 50€ so it's too much for sure. (I didn't find 8400, it was 6200) No I'm not going to spent that much to my mythfrontendbox. Probably not even 20€.
I tried to build Minimyth with Nvidia Legacy drivers and that is option for building system and building failed (some error, which I might check later). I didn't try to boot Minimyth with Nvidia Legacy drivers because there is none avalable (AFAIK).jamesarbrown wrote: As you have that, maybe xorg is not working.
Or does 'offical build' have those drivers? If they do, I must figure out how to get it working 'cause currently it fails to mount root filesystem. Don't exactly why. I have had minimyth-72-0.21 with nvidia 96.xx.xx drivers working, but 75-0.23 has some trouble.
Can you just install Nvidia Legacy drivers to Minimyth RAM? I thought it isn't that easy.
I know enough to SSH to minimyth install and write a Xorg.conf, but I thought Minimyth wants it Minimyth's own way.
I am not sure that MiniMyth can run with 320GB of RAM. By default MiniMyth runs from a RAM based root file system and has no cache partition. It might work if you use a very lightweight MythTV theme and do not load and MythTV plugins. If this is not enough, then you might be able to get it to work by running the MiniMyth root file system from Flash and not load it into RAM. However, this takes some work as it is not a standard MiniMyth operating mode. Alternatively, you might get it to work by creating a cache partition on a NFS network share.
Anyway, you could 0.23.1-76b2 a try with MM_X_DRIVER='nouveau' in your minimyth.conf file. The Open Source nouveau driver has been really coming along. In fact, on my Asus M3N78-VM, I have been using the Open Source nouveau driver rather than the proprietary NVIDIA driver. I had never needed XvMC on this frontend as the CPU is fast enough to decode MPEG2 SDTV and HDTV in software.
In case that does not work, I have uploaded 0.23.1-76b2-nvidia.96.x.x as well so that you can test with that.
Pablos right, if it does not support xvmc your in a corner..... my C3 fanless (same as yours but yours has fan? so mine is a bit slower), but mine can no where near run video without xvmc running. So I am really doubtful the 1ghz will even pull it off.
Mine just sits there CPU Util at 100% on 720p, stuttering audio, stuttering video, once xvmc is up, processor runs <10%.
So if you want to use that MB maybe you need a new display card with hardware video offloading eg vdpau maybe?
Memory is easy to get and upgrade if needed. When I built my mythtvfrontendbox I didn't have more and it seemed to work with minimyth 72.
If I must buy a new graphics card, which one would work with my mobo and case (AGP, lowprofile) and could do XvMC (MPEG2 decoding) and interlacing (for RGB Scart output). I'm trying to find a used one (for now at least). Would something from GF 5xxx series work fine?

Thanks. I'll try both ways (noveau and nvidia-96).Pablo wrote: In case that does not work, I have uploaded 0.23.1-76b2-nvidia.96.x.x as well so that you can test with that.
Darn... no AGP with VDPAU
So yes its XvMC and mpeg2 only for you
JamesAny recent version of the driver is acceptable. See the Nvidia page for more details. Be careful though: some nVidia cards do not support XvMC: the only cards that support XvMC are those that support nVidia "PureVideo", which is not the case for most motherboard GPUs such as the GeForce 7 series. Geforce 8 and later do not support XvMC. This is a hardware and driver limitation. Use VDPAU instead. The latest NVidia driver packages support XvMC on hardware which supports XvMC instead of VDPAU.
"The 173.14.09 release includes support for the XVideo Motion Compensation (XvMC) version 1.0 API on GeForce 5 series, GeForce 6 series and GeForce 7 series addin cards, as well as motherboard chipsets with integrated graphics that have PureVideo support." 
That's all I need.jamesarbrown wrote: So yes its XvMC and mpeg2 only for you
If I understood correctly any 5000-7000 card is fine. Which means I could buy a GeForce 5200 (128 Mt, Low-profile, AGP) for about 18€ with shipping costs. Can it do interlacing and low-dot frequency (14,76 MHz) on VGA? I have RGB SCART on my mind: http://www.mythtv.org/wiki/RGB_Scart
I can see RGB scart couplers here :-
http://www.tvcables.co.uk/cgi-bin/tvcab ... op=eq.html
And more detail on RGB here
Hope it helps.
I replaced my VIA hardware with Intel Atom + NVIDIA ION hardware some time ago and it works well with VDPAU as long as I use the proprietary NVIDIA drivers. In the future, I would love to use Intel hardware for both CPU and GPU because Intel is making an effort to support Open Source. However, the VA-API support is not there yet.jamesarbrown wrote:Yes a nightmare.. and in mythtv 0.25 xvmc and libmpeg2 will be dropped totally.
So it looks like VDPAU is way forward... so a lot of us will be needing totally new hardware.
