I installed Precise from scratch on a Thinkpad T420s with NVIDIA Optimus. The BIOS is configured to "Discrete graphics", i.e. Optimus is turned off, and the NVIDIA video card is turned on, and it is the only card visible from Linux. After the installation, I added the proprietary NVIDIA drivers and rebooted. This gave me nvidia-current-updates 295.49-0ubuntu0.1 I then suspend the machine, either by closing the lid, hitting Fn+F4, selecting suspend from the system menu, or running pm-suspend. When I then resume the machine, either by hitting Fn or by opening the lid, the LCD backlight comes back on but remains black, and the machine freezes. After a while, the CPU fan hits max. I cannot SSH into the machine. There is a link light on the Ethernet, but no activity light. This problem persists also with other versions of the NVIDIA driver, such as nvidia-current 302.17-0ubuntu1~precise~xup1. The problem disappears if I switch to Integrated Graphics, and use the intel driver. I have found no obvious way to get at the syslog or Xorg log files to get an indication of what or how this locks up.
