Symptoms

warning message is displayed “Check your video drivers. Your system is currently running without video hardware acceleration. You may experience poor performance and high CPU usage”.

Solution

Your graphics device 4e71 is not properly supported by the driver in this kernel version. To force driver probe anyway, use i915.force_probe=4e71

As it is specified in the error message, a device with PID=4e71 should be added to module parameters.

Open /etc/default/grub and add the parameter to the kernel command line:

GRUB_CMDLINE_LINUX="i915.force_probe=4e71"

Then updat grub:

sudo grub-mkconfig -o /boot/efi/EFI/debian/grub.cfg
