I launched xbmc with:

Code:
GALLIUM_HUD=requested-VRAM xbmc

And it showed ~180MB requested vram playing some 60 fps 1080p clips. Is that the real vram usage?
+ UVD Memory (which is max 256 MB)

so: 256 + 180 = ?
First decide what functions / features you expect from a system. Then decide for the hardware. Don't waste your money on crap.

Thanks. Right now I'm using 384 and it works fine (never stuttering or anything like that) I'll set it to 512 when I get another 2gb stick
since a week or so I get a xbmc compile error allready during autoreconf complaining about java missing. OpenJDK 1.7 is however installed. Why is there java needed anyway?
Here the log:

This time it is not ccache, cause thats uninstalled. Also I re-downloaded the complete source from git several times.
I am on mesa 10.0.3, opensuse tumbleweed (kernel 3.13.3) - but also testet with mesa 10.2 git, E-350 system.

thanks, tomme

thanks - good hint
I am such a linux noob still after 10 years desktop usage :/
however package management said java was installed, but "which" told the truth - I re-installed java, and now it works and is compiling right now Smile

Which just told you that the java binary is/was not on your users path (where it searches for the binarys) reinstall may have added the binary location to your path but may be otherwise completely unnessecary.

Looks like we should expect qvdpautest to show lower values in a future kernel.

Yes, this is drm-next material.  thanks!

I checked in the BIOS settings and the amount of RAM shared with the video card is "auto".
I use the HTPC also as file server, so "Auto" seems the best option, i.e. use the maximum amount only when needed.
What are the side effects of setting "Auto" in the BIOS settings for the amount of VRAM?
Auto is: what you bios wants to give. It does not change on the fly -> don't use it.

A few words on those updates?
Hi! I've got this notebook which I thought to use as xbmc fr watching live tv from tvheadend (no HD channels so really do not care about hdmi etc issue). I was trying to install sausy on it but right after first screen somehow the internal keyboard is blocked and I cannot even start installation... ANY IDEAS?
use the server iso and select "minimal" when pressing F4 from the bootloader
