Updated and Optimized Ubuntu Free Graphics Drivers

[Azrael5]

I use a hd3850 agp on my motherboard and consulting datas the results is different in confront of hardware features:

256MB gddr instead of real 512MB
32bit width instead of 256bit width.

How to correct this values?

Where do you read that values?

I've red them by terminal and using a diagnostic tool I got by Ubuntu Software Center.

VGA compatible controller: ATI Technologies Inc RV670 AGP [Radeon HD 3850] (prog-if 00 [VGA controller])
Subsystem: Hightech Information System Ltd. Device 0028
Flags: bus master, 66MHz, medium devsel, latency 64, IRQ 16
Memory at d0000000 (32-bit, prefetchable) [size=256M]
I/O ports at d800 [size=256]
Memory at fbff0000 (32-bit, non-prefetchable) [size=64K]
Expansion ROM at fbfc0000 [disabled] [size=128K]
Capabilities: <access denied>
Kernel driver in use: radeon
Kernel modules: radeon


I've consulted again the vga parameters and I noted the 256 value is present although the memory is limited to 256MB value.

That's most probably the size of your AGP GART and not of the graphics cards. Run "dmesg | grep VRAM" to get the size of your graphics cards RAM.
