My computer is an Asus FA506II with AMD Ryzen 7 4800H and Nvidia GTX 1650ti. I have installed Ubuntu 18.04 with default window manager (gdm3). After the “nouveau” disabling step it seems that nvidia-430 (after ppa settings and apt-get install nvidia-driver-430) driver can successfully serve the screen at the internal LCD of laptop.
But when I connect the computer with second monitor over HDMI output, the computer couldn’t detect the HDMI. I am using same monitor and cable setup with other computers successfully.
When I activate #Option "PrimaryGPU" "Yes" line the computer doesn’t reach the login screen and I can only see the fsck output report of booting process. So I have get two version of logs, the first one with this option and the second one without this option. I am attaching link of both below:
Thank you very much for your knowledge-full and helpful reply. Now everything is same as your reply mentioned. I can see the external monitor as extended screen over the HDMI output.
Only I want to ask a situation. When I just boot the computer I couldn’t see the external monitor until I change active tty by CTRL + ALT + F . If this problem wouldn’t be solved I can easily use changing active tty as a work around. But I am attaching two the logs as after boot and after tty change.
