Actually, I am pretty sure that the problem is that the brightness is maxed out. I installed spicctrl, and it reports it is set to 224. But the Fn key to control it does not work, and I cannot run this command until I am logged in.
After doing ctrl-alt-f1, how does one get back to the graphics mode?
The sony fn key stuff is supposed to be in the kernel, how do I activate it?
