I'm struggling with running a Live USB Pen Drive with Debian 10.10 non-free iso in my Lenovo Ideapad S145. But trying with or without UEFI support can't start the system. It stays halted on a black screen. I think this is probably because of lack of the video driver in the Live CD, but I'm not sure of.

Follow are the screens that maybe can help to find out why.

BIOS Boot Configuration: BIOS Boot Configuration

Selecting Debian Live: Selecting Debian Live

The last message before enter into black screen: The last screen before black

So that was the screen info.

Now, what I could extract from my current Ubuntu 20.20 installation about the video driver firmware.

lspci -v:

00:02.0 VGA compatible controller: Intel Corporation Device 8a56 (rev 07) (prog-if 00 [VGA controller])
  Subsystem: Lenovo Device 3fdc
  Flags: bus master, fast devsel, latency 0, IRQ 152

  Expansion ROM at 000c0000 [virtual] [disabled] [size=128K]
  Capabilities: <access denied>
  Kernel driver in use: i915
  Kernel modules: i915

lshw -c video:

modinfo i915:

filename:       /lib/modules/5.8.0-63-generic/kernel/drivers/gpu/drm/i915/i915.ko
license:        GPL and additional rights

author:         Intel Corporation
author:         Tungsten Graphics, Inc.

From modinfo i915 output, we can see that the current video driver has a GPL and additional rights license.

By all the output I posted here it seems is a problem with the i915 Intel driver. Could it be for another reason? Is there a way of running Debian 10.10 Live USB, or I will have to install Debian first without video support, and after that try to install the video driver?

    Have you tried Debian bullseye (as suggested here)? According to Lenovo it's an 8th gen. i5-8265U, UHD Graphics 620?

  • You got it @Freddy. The Bullseye RC2 nonfree ISO Live with 5.10 kernel runs very well and the firmwares for both wifi and video looks like working very good. Thank you very much.
