Description Daniel Hill 2011-04-29 20:46:24 UTC 
Is this suppose to be low as ~200MiB. on my other computer, running radeon, it's ~500MiB with a 512MiB (RV710)

Comment 2 Michel Dänzer 2011-05-02 02:27:37 UTC 
What 'VRAM limit' are you referring to? The attachment shows the whole 1G of VRAM being used:

[drm] radeon: 1024M of VRAM memory ready
Comment 3 Daniel Hill 2011-05-02 20:07:32 UTC 
sorry I was pretty sure I attached the Xorg.0.log will attach it soon
Comment 4 Michel Dänzer 2011-05-03 01:47:59 UTC 
I assume you're referring to the line

(II) RADEON(0): VRAM usage limit set to 111700K

then. This just means that the X driver doesn't require more than this amount of VRAM (limited to the maximum amount of VRAM that can be accessed by the CPU) in a single command stream submitted to the kernel. This doesn't prevent all of VRAM from being used.
