help me please I see solution for intel but not for amd. I’m newbie in linux please give me full instruction.
Please run nvidia-bug-report.sh as root and attach the resulting .gz file to your post. Hovering the mouse over an existing post of yours will reveal a paperclip icon.
you can use pastebinit to upload it from console.
- switch to VT (ctrl+alt+f1)
- log in
- install pastebinit (sudo apt install pastebinit)
- run the script (sudo nvidia-bug-report.sh)
- unzip logfile (gunzip nvidia-bug-report.log.gz)
- upload logfile (pastebinit -i nvidia-bug-report.log)
- note down and post the url you’re given
Ok, that’s a true hybrid graphics setup using an integrated amd vega and a dicrete nvidia gpu. I suspect Ubuntu’s automatic setup for hybrid graphics doesn’t catch that yet so everything gets confused. So you will have to set it up by hand.
As a first step, please exchange GDM for lightdm to avoid known bugs with it
sudo apt install lightdm
at the end of the installation, it will ask you which you want to have as default display manager, choose lightdm. Then reboot, log in and create a new nvidia-bug-report.log
After i switch to lightdm and reboot i got black screen from graphics mode but i can use console from ctrl+alt+f1
how to fix black screen?
“The Paste you are looking for does not currently exist”
Wong pastebin url?
now i lost wifi connection
i can’t connect wifi in console how to switch back to gdm?
sudo dpkg-reconfigure gdm
Ok, your xorg.conf is broken. Please edit it and replace
then enable lightdm again
sudo dpkg-reconfigure lightdm
and reboot, create a new nvidia-bug-report.log
The exact file is /etc/X11/xorg.conf
Looks like you now have a proper working X session on the amd gpu running. Anything not working?
ERROR: NVIDIA driver is not loaded

** Message: 08:31:37.395: PRIME: is it supported? no
how i can use nvidia gpu?
Ok, now let’s see if you can switch to nvidia. The v430 driver from ppa already seems to be installed.
Please make sure the package nvidia-prime is installed
sudo apt install nvidia-prime
Try switching to nvidia:
sudo prime-select nvidia
Remove any stray blacklist files:
sudo rm /etc/modprobe.d/blacklist-nvidia.conf /lib/modprobe.d/blacklist-nvidia.conf
Update the initrd:
sudo update-initramfs -u
and reboot. Please create a new nvidia-bug-report.log afterwards.
Ok, the kernel driver is loaded but it’s not yet picked up by the Xserver.
Please delete /etc/X11/xorg.conf
and modify /usr/share/X11/xorg.conf.d/10-amdgpu.conf
