Hi,

I am running Arch on an Aero 15x v8 with proprietary nvidia drivers and bumblebee and I have noted something when using X that I don't see in the thread (well it echoes the 2 consecutive lspci launch crashing the system). I dont know if it'll be of any use to you though.

When starting X using just X command without root privilege, X complains because he wasn't launched with root privilege (can't open /dev/tty0)

And when doing that a second time it just freezes the system right after printing the initialization messages out ("Using system config [...]")

Once again I launched X unprivileged both times

But launching any application with optirun between the 2 X calls prevents the second launch from crashing the system.

So I guess optirun must "reset" dôme value somewhere that has been set by an unprivileged operation.

It can be reproduced lauching lspci or lspci, lshw or X (ex : lspci, X -> crash, lspci, sudo optirun cat /etc/fstab, X -> no crash)

So what do lspci, lshw and X do that can be "reset" by launching optirun?
