Hello,
thanks for the feedback and testing, very appreciated.

Hello,
currently we are testing our updates of ported Linux drivers
[https://github.com/genodelabs/gnode/issues/4798] 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.
Both [3] and [4] work for me on Thinkpad X201 and Latitude E6440. Blue,
green, red, a blue-green pattern, and black-and-white regions.
I don’t have an external monitor to test out, though.
If [3] and [4] does not work (or one of them), it would be nice, to
give the 5.14. based driver [5] a spin. With this information we can
see, whether it never worked on your system or it is really a
regression due to the update to 6.1.
If it works for you, it would be good to know about. If it does not
work, it would be even better to know about.
In both cases, the specification of your hardware would be
appreciated. If you don't want to spread the information publicly, you
may also write me a direct message. Luxurious support would be, if you
can send a captured trace via uart/serial/amt [6] in case something
does not work for you. Please send captured logs directly to me, just
to avoid spamming the mailing list.
Thanks for your support & have a nice Easter,
Alex.
