Thanks! It appears your laptop only has an Nvidia GPU. Although an Intel GPU should be present, it's not detected. Most likely disabled in the BIOS. That should be OK...
Also your Xorg log is reporting that the Nvidia driver has successfully detected the internal display, which is 1920x1080 and is an LCD panel manufactured by Chimei. Your 'prewboot2.txt' seems to suggest maybe the remaining problem is just that Ubuntu doesn't know how to properly control the display backlight. Please run this command: find /sys/class/backlight/ > backlights.txt and send us the file 'backlights.txt'. ** Package changed: gdm3 (Ubuntu) => nvidia-graphics-drivers-418 (Ubuntu) ** Changed in: nvidia-graphics-drivers-418 (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gdm3 in Ubuntu. https://bugs.launchpad.net/bugs/1830673 Title: [nvidia] startup bug Status in nvidia-graphics-drivers-418 package in Ubuntu: Incomplete Bug description: when I start computer it sometimes remain stuck in starting procedure showing it instead of loading screen. Gnome will not start. Commands does not work at least on this console. I have to force restart computer. Another time the starting procedure shows, but is overtaken afterwards by standard loading screen which is little stretched to sides. It started appering after migrating from novaeu to Nvidias driver.
