#203698 — Re: Latest kernel gives blank screen when it boots

I faced the same problem for 3 days until I found your thread here.  Tried to 
setup an old laptop with Intel graphics with Debian testing 9.6. The laptop was 
running Lubuntu for years happily. inxi reports it only as "Intel Core 
Processors Integrated Graphics".

I could only avoid the black screen on boot after grub with "nomodeset" but then 
was stuck with 1024x768 px and xrandr reported my display only as "default".

Maybe to help someone else finding this, here is a list of things I tried 
WITHOUT ANY effect:

- Install: firmware-linux-nonfree firmware-misc-nonfree xserver-xorg-video-intel
- CONFIG_FRAMEBUFFER_CONSOLE=y was already active

Setting various grub parameters:

- i915.preliminary_hw_support=1
- i915.modeset=1 video=LVDS-1:d"
- intel_idle.max_cstate=1
- acpi_osi=linux
- acpi_backlight=vendor
...
 
I downgrade to 4.9.0-8 from stable cause nothing in between was offered. How can 
I downgrade to only 4.18.0-2? Or have you tried 4.19 in the meantime?

Best regards,
Martin

Which thread ? There is no Message-ID reference in your post headers.

If the GPU is Intel 4/5 Series, you may be affected by a regression 
introduced by a change in the 4.18 kernel i915 driver. See
<https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=914495>

This effectively disables the i915 kernel driver.

Not personnally, but the bug is reported to be fixed in kernel 4.19 
which is now available in testing.

I always get a blank screen when running linux, that's why I install
using the s boot parameter and can hear everything being spoken.
alt-super-s gets me gnome-orca once that gets installed too.  I never had
enough money to afford a braille screen so the speech is helpful.
