This is a "new" problem (maybe began several weeks ago, I don't know when it first started) and occurs like once every 1-2 weeks or so, at least when I notice it:
The system suddenly freezes. This is when I'm doing random stuff on the xfce4 desktop. Now I hit CTRL+ALT+F1 to switch to a VTT and the screen goes very slightly darker! The desktop picture remains frozen though, VTT is not popping up. I can't do anything, but if I wait for like a minute (haven't timed it) suddenly everything is back to normal (and I find myself in the VTT 1 and can switch back to X and resume doing whatever I was doing).
I have no idea what's going on so I just typed "dmesg" and got this, any useful?

Hi,
It happens to me too. Since I installed Arch (1-2 months), I have this issue. It doesn't happen when I use it, but after a long period without activity (at least one night). I am using Enlightenment as window manager.
My graphic card is a NVidia Optimus, where only Intel is enabled.
Thanks
Daniel
