Hi,
after nearly 20 years of happiness with Debian distros I am struggling
to get Debian buster working on a Dell Inspiron 14 2-in-1.
The installer completes, but I have no working wifi and no working graphics.
Let's concentrate on the graphics for now, since it is more urgent. The
laptop has an i7-10510U which should come with an embedded UHD 620
graphics and also a discrete nVidia MX230 GPU. I have tried following
different ideas found on the web but with no luck. My guess is that the embedded graphics is not recognized by the driver and that MX230 does
not work with nouveau, but here are some details. The following tests
have been done on a fresh install (kde task selected in the installer
with only firmware-nonfree, firmware-iwlwifi added afterwards).
First hist: I have only /dev/dri/card0 and /dev/dri/renderD128 and they
both seem related to the nVidia card; I do not seem to have any /dev/dri
entry for the Intel graphics.
Starting X server does not work and /var/log/Xorg.0.log contains
[???????? 9.948] (II) xfree86: Adding drm device (/dev/dri/card0)

and then loads the modesetting, fbdev, vesa, fbdevhw modules and finally
fais with

for all framebuffer devices
If I start X with a configuration file containing only
Section "Device"
?? Identifier "Card0"
?? Driver "intel"
???? BusID "PCI:0:2:0"
EndSection
then it fails with

(Note that the i915 is loaded, but upon loading it does not create a

On a side note, I have tried to upgrade the kernel to the 5.2 in buster-backports but both bop.2 and bop.3 packages result in unbootable kernels: the boot process just hangs somewhere. I have uninstalled them,
but if you think that a newer kernel may help I can try to reinstall and
boot it without the quiet option to see what goes wrong.
Thanks in advance for any suggestion.

<p>On a side note, I have tried to upgrade the kernel to the 5.2 in
buster-backports but both bop.2 and bop.3 packages result in
unbootable kernels: the boot process just hangs somewhere. I have
uninstalled them, but if you think that a newer kernel may help I
can try to reinstall and boot it without the quiet option to see
what goes wrong.</p>
<p>Thanks in advance for any suggestion.</p>
<p>Best</p>
