    I'm not aware of a command to display vram size but check aticonfig -help output.

      Same, it's trying to allocate all RAM to the video card.

      Removing 2gb of RAM from the system fixed the issue but it's going back in, I need to virtualize & this is clearly a Linux bug.

        My understanding from the devs is that problems with 4GB RAM are usually related to system BIOS problems - some of them can be worked around in the driver but others require workarounds in the OS, at least that's what I picked up from a hallway discussion. Checking for system BIOS updates is always a good first step - don't know if there are known issues on your specific hardware though...

          Haha!

          Well I found like 10 different threads from different forums describing in different words the same problem, mostly with the A350 Toshiba.

          So I thought I would go caveman & tried Ubuntu 10.10 alpha, and guess what? The devs must have listened coz it's fixed, with hardware effects and all.

            problem is solved

            the problem can be solved also in all earlier linux distributions (ex. openSuse 11.2, Ubuntu 9..., Debian 5). When we boot the system, just write in command line in GRUB below option:

            pci=use_crs
