Hi, Please find attached the patches which I currently use on my desktop machine for dual head with the randr branch to fix the issues which I found. They may help others as well but may e.g. also disable the Xv blitter which might be working for some (but didn't on my card) - more information is found in the text comments in the patches. I have to hurry so this is short, will be back.

Add virtio_gpu_queue_ctrl_buffer_nolock function, which does the same as virtio_gpu_queue_ctrl_buffer but does not take the virtqueue lock. The caller must hold the lock instead.

I'll change it. cheers, Gerd
