if I turn on or restart the computer with the eGPU connected it does not turn on, it stays black …
I have always connected eGPU after login in ubuntu …
and then logout again. but it does not work,
do you have any idea
and now it doesn’t recognize my ethernet connection …
sorry
Please check if removing it from the bus and adding it back makes it work:

think they were erased … right?
but when i reboot, it continues to black out the screens
Get a root shell first
sudo -s
and then just run the commands without sudo
Don’t reboot after you issued the commands, instead run
sudo dmesg >dmesg.log
and attach the output file dmesg.log to your post.

Looks like the nvidia gpu should be accessible, the driver loads after issueing the commands.
It is the first time that it appears in months … :)
I had to change the driver to 435 … it doesn’t work with cuda … you know why?
and I have a monitor connected and it’s still black
do you have another suggestion
Thanks a lot
sorry for any inconvenience
Why did you have to revert the driver to 435?
To have the Desktop expanded to the nvidia outputs,
modify /usr/share/X11/xorg.conf.d/10-amdgpu.conf
replacing only
Driver "amdgpu"
with
Driver "modesetting"
Please add inside the OutputClass of /usr/share/X11/xorg.conf.d/10-nvidia.conf
Option "PrimaryGPU" "Yes"
Option "AllowExternalGpus" "true"
Then create two files optimus.desktop in /etc/xdg/autostart/ and /usr/share/gdm/greeter/autostart/ containing
[Desktop Entry]
Type=Application
Name=Optimus
Exec=sh -c "xrandr --setprovideroutputsource modesetting NVIDIA-0; xrandr --auto"
NoDisplay=true
X-GNOME-Autostart-Phase=DisplayServer
Then log out, switch to VT (ctrl+alt+f4), log in and restart gdm
sudo systemctl restart gdm
Why did you have to roll back the controller to 435?
I don’t know why, but it was the only way it worked … :(
Regarding the external monitor, I did what you suggested. after
sudo systemctl restart gdm
The purple screen appears on the external monitor and I log in, but after a few seconds (black screens) the purple screen comes back and I login again, … and again and again (I don’t log in)…:(
sorry. it worked with 440 nvidia driver…
understand that to configure the monitor use the GDM software.
Thank you generix
Please create a new nvidia-bug-report.log in the current state.
Hi @generix , I’ve done everything you mentioned above but still won’t be able to get it working. I have retried a couple times as well. Could you please take a look?
The setting is MacBookPro + RazerCoreX with Geforce GTX1080 Ti on Ubuntu 20.4.2 and nvidia-driver 460.
