Meanwhile, the 6700M, 6800M, and 6900M could all benefit from dynamic switching (assuming the bugs and other issues are worked out), but no one is doing it.
How have laptops with AMD switchable graphics fared in terms of driver updates over time?
Does AMD’s switchable technology work any better under Linux that NVIDIA’s Optimus?[/quoteLinux support is terrible: unlike Optimus where it usually at least has the decency to use the Intel GPU with the Nvidia one turned off, with dv6t, the discreet GPU is running (I can tell by the thermal behavior), but no drivers for it can be installed and there appears to be no way to use it. It's partially my own fault for using Scientific Linux (it's the latest 6.1 release, but the kernel is still rather old). I will try with Fedora 16 once it comes out, but my only goal is to get the Radeon card to turn off and be able to control the brightness -- actually switching between GPUs is highly unlikely.
