I am getting seemingly random crashes of X.
I have 3 monitors (2 external, 1 laptop), and occasionally they will
flash black, and orientation gets reset to default. I have not been able
to find any action that specifically triggers this, although when i look
at dmesg, it seems to somehow be relate to my wifi. I have pasted (what
I think) are the relevant bits of dmesg below, please let me know if I
should provide more info.
dmesg first instance:
