No joy ...good read though. It seems the nvidia bios area is not defined /read by the kernel mtrr ,hence the read on the character node failure on rw /dev/nvidia0 ,whereas the /./nvidiactl is attempting to communicate with the bios of the nvidia adapter ,this causes the failure to load the nvidia driver in the first instance ,the result can be reproduced when nvidia-smi -l is invoked ,you should see the errors ,ptrace and strace for the c node show very little . If somebody can get the system bios area defined during boot /init,windoze (tm) defines it but to re-define it in memory map would be great . Cheers .

I can provide any info you want, just ask :)Regards, D3X On Thu, 3 Jun 2010, Shane Volpe wrote:All, I just purchased a ThinkPad T410s with switchable graphics and would love to help out with switchable graphics support in Linux.
