Hello friends.
I have Ubuntu 16 with several 1080 ti.
Connecting in ssh. to control fans i used
DISPLAY=:0 XAUTHORITY=/var/run/lightdm/root/:0 nvidia-settings -a [gpu:0]/GPUFanControlState=1
DISPLAY=:0 XAUTHORITY=/var/run/lightdm/root/:0 nvidia-settings -a [fan:0]/GPUTargetFanSpeed=80
All works fine!
But today my computer turned off because of electric power.
And now, after boot i have error when using this commands
DISPLAY=:0 XAUTHORITY=/var/run/lightdm/root/:0 nvidia-settings -a [gpu:0]/GPUFanControlState=1
Failed to connect to Mir: Failed to connect to server socket: No such file or directory
Unable to init server: Could not connect: Connection refused
ERROR: The control display is undefined; please run nvidia-settings --help for usage
information.
Obviously, no Xserver running that nvidia-settings could connect to.
Already rebooted?
Please run nvidia-bug-report.sh as root and attach the resulting nvidia-bug-report.log.gz file to your post. You will have to rename the file ending to something else since the forum software doesn’t accept .gz files (nifty!).
and the Xserver is outright crashing.
The gpu connected to the bridge is pci id 09:00.0, locate it, remove it, check if the system then works. Afterwards, plug it back in, maybe it’s just a bad slot connection.
