I have an xubuntu 20.04 PC connected to a 40″ Samsung TV. Xfce / Lightdm is set to autologin. When it logs in, the detected display is wrong (it just says “default”), and the screen resolution is locked to 1024×768 according to Setting Manager -> Display. However, if I logout, then immediately log back in again, the display is correctly detected as ‘Samsung 40″‘ and the resolution is correctly set to 1920×1080. I’m using the proprietary nvidia drivers (from Settings Manager -> Additional Drivers) for my GTX 960 card. I’ve tried the suggested tricks of putting “xrandr –output HDMI-0 –mode 1920×1080” in the config, but that doesn’t fix it. Any ideas?
