I just installed Ubuntu 20.04 on my ASUS UX431F with intel HD620 graphics
No display: On every boot (on a live key or on the installed distribution) i have to add nomodeset to the grub othezwise the screen stays black. Besides that, everything start up correctly (i can ear it and run a reboot command)
No brightness control: The keybord keys don't work and the menu is invisible. When i add to the grub :
quiet splash nomodeset acpi_backlight=vendor
i does display a control bar in the power menu but i doesn't work.
I tried various softwares and commands, I added various instructions to the grub script but there is no solution.
The weird things are :
- I can't get rid of the nomodeset command because the software and driver settings doesn't display any available drivers
- Some solutions online advise to fix Brightness by configuring X11. But I can't find this xorg config file, my computer seems to not have it
- The displayed graphic card isn't my Intel HD : llvmpipe (LLVM 10.0.0, 256 bits) details
I hope somebody here has any idea or way to solves this
