Hi, My workaround was to (boot in recovery mode and) blacklist nouveau, as in:
# echo 'blacklist nouveau' > /etc/modprobe.d/blacklist-nouveau.conf After that, reboot in normal mode. It seems that the 3.13.x kernel is trying to load drivers for both the Intel and NVIDIA cards, and there's a BIOS-related bug that makes the NVIDIA card misbehave when on Linux. Previous versions of the kernel didn't do that. I hope that helps. -- John.
