Hello,
currently we are testing our updates of ported Linux drivers [0] on
various generations of Intel hardware.
The available test hardware in the lab works fine, so far, but we can't
be sure whether it applies to all systems out there.
You may support us, and thereby the next Sculpt release, by test driving
the prepared images. The images are bootable via USB stick and can be
prepared similar as documented for Sculpt [2]. With the tests by you, we
may detect regression earlier, e.g. before the Sculpt release.
The test is very simple (and not sensational at all) and cycles through
some test pictures. When external monitors are attached, the test
pictures are mirrored across all connectors. The resolution changes
automatically to the largest resolution available, so that monitors with
smaller resolution will just show a part of the test picture (so, it is
expected behavior).
Image [3] contains the driver based upon Linux kernel 6.1 as be part of
Genode staging branch.
Image [4] is a variation, which tries to use more of the drm/kms
interfaces [2] (and is still work-in-progress).
Ideally, both just work. Please also try to attach/detach connectors
multiple times to stress the driver a bit.

Sorry for the delay in running these tests, but I am happy to report
that both 6.1 images worked fine on my ThinkPad L380 Yoga (with 16GB
RAM) [1]. I tried it both with and without the external monitor, as
well as plugging and unplugging the HDMI cable as quickly as I could.
If you have any more test images, I will be happy to test those also
(hopefully more quickly)!
Thanks!
