I run Ubuntu 23.10 Mantic on a Lenovo laptop with nVIDIA GeForce RTX-2060, but I use only nVIDIA graphics, not the built-in Intel, by selecting “Discrete Graphics” in the BIOS.
As I am not happy with Wayland, I still use X11.
I login using Gnome, so version 45, and not Ubuntu.
I have 2 issues:
At startup, just after logging in, I need to wait almost a minute after clicking to e.g. open a terminal or Thunderbird before it really opens.
external monitor issues
When I run VLC on an external monitor via HDMI, the frame rate of 29.7 fps is not reached, a movie looks very bad and delayed.
I also installed XFCE4 and can login in XFCE, there both issues do not exist.
