If nvidia card is switched back on, problem dissapeares. This is caused by nouveau driver not returning VGA connector status properly. When upowerd tries to read status of all connectors, it hangs waiting for VGA. Gentoo Linux kernel: 2.6.38-rc* xorg-server: 1.9.4 upower: 0.9.8 KDE: 4.6.0 Steps to reproduce: 1. Log in to KDE 2. switch off nvidia: echo OFF > /sys/kernel/debug/vgaswitcheroo/switch 3. cannot read VGA connector status:...

Does it make sense we deregister the sysfs files when the hardware is placed in D3 or return EIO or such? Hardware info at [4]. Th...
