I have installed Kubuntu 22.10 on an old Acer laptop and a no-name desktop. Neither are showing a grub menu on startup so I can't get to safe mode or a command shell to solve a display problem. I've run update-grub2 and it finds the boots (this is the desktop but the laptop is the same):
sudo update-grub2

I have LG 1360x728 monitor and a Dell 1280x1024 displays on the desktop and the boot fails with an error on the display configuration. On both screens. I managed to run the installer in safe graphics mode but when I rebooted I got the display configuration error. I have a workaround which involves unplugging the LG, booting to the 1280x1024, plugging the LG back in and running xrandr to create the 1360x728 resolution, adding it to the display and activating it. I thought that installing the driver from the nvidia site might be an answer but I can't get past the install without errors.
I've tried adding an autostart shell script to do the xrandr but the boot seems to be blocked by the

I'm at the point of retiring the LG and looking for a new second monitor unless you have any suggestions...
