Created attachment 279831 --> https://bugzilla.kernel.org/attachment.cgi?id=279831&action=edit Driver Traceback

The problem is proteiform. It is actually well described in https://bugzilla.kernel.org/show_bug.cgi?id=156341 so this could be a duplicate, however, since the driver supposed to actually drive the nvidia GPU is nouveau, I feel obliged to fill a new bug report to address the issue.

So basically, there is two issues:

1. when loading the nouveau driver in a tty, you can't launch Xorg afterward, the xinit program waits for a server to be available but that never come. 2. When loading the nouveau driver after the X session has started, the fan finally switches off, but there is first a traceback in dmesg and everything that is reported in bug_id=156341 happens: subsequent calls to lspci/lshw/... are freezing the system definetely without possibility to recover except by doing a hard reboot.

So there's definitely something messy about this familiy of Nvidia GPU integrated as a discrete GC on this new laptop generation.

Can't give much more info

See attachment for the traceback.
