So, I have fresh install of Ubuntu 22.04 alongside Windows 10 (on separate drive). I have Nvidia GTX1050 GPU with Dell U2414H monitor via HDMI. Everything works fine, except for one small quirk. On boot, when it gets to login screen, my monitor instead goes black. Only messages I see on boot are
[...] mtd device must be supplied (device name is empty) [...] mtd device must be supplied (device name is empty)The weird thing is that I can easily fix that black screen by doing one of the following:
- Reconnect HDMI cable;
- Turn monitor on and off;
- Go to tty3 by ctrl+alt+F3 and then back to login screen by ctrl+alt+F1;
- With black screen, press enter, blindly enter password and press enter again.
All of that makes screen work fine. I am also experiencing this problem when logging out (getting black screen instead of login). I can see that monitor backlight is on, but for some reason monitor buttons (which open menu with settings like brightness and input source) do not work.
Looking at dmesg I see some nvidia errors:

With Nouveau it works fine. It also happens regardless of using Wayland or XOrg. It's not serious, but it bothers me to go through these motions every time on boot/logout.
Here's some info:
