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
