Problem with login screen on Kernel 5.8.0-59/63 and Ubuntu

Asked by mmm

I have problem with black screen instead of login page with Ubuntu LTS. The problem appears on Kernel 5.8.0-59 and 5.8.0-63. When I use these versions, a black screen pops up instead of the login screen and I can't do anything (when I temporarily connect an external monitor via HDMI (when I see black screen on internal display), I see a purple screen and cursor, but there is no login window) - I also have a USB-C -> DisplayPort 1.4 output in my laptop, but I do not have the appropriate cable to check if something is displayed on it. I only use the internal display on a daily basis. When I add "nomodeset" to "GRUB_CMDLINE_LINUX_DEFAULT" the system loads, but it takes a long time and doesn't run perfectly smoothly.

I have an HP Pavilion Laptop 15-eg0009nw / Intel i5-1135G7, 2x8GB DDR4, Intel Iris Xe and 512 GB PCIe NVMe M.2 SSD.

The only Kernel version without problem on system start that works with my laptop is 5.8.0-43.

Thank you.

Do you need the HWE in your system?

Thank you for your reply.

I installed Ubuntu LTS with internet connected and there was Kernel 5.8.0-59 right there, and today the system itself has updated it to 5.8.0-63.

Sorry, but I don't understand the question about the HWE ...


When I set the default entry to Kernel 5.8.0-43 (with Grub Customizer), the following message pops up before booting the system:
error: can't find command 'hwmatch'

But the system starts normally and I can log in.
