Dear Maintainer,
I installed Debian 11 on a new computer (with a single monitor during
installation, connected with HDMI).
Installation went well, but the monitor came up with a very limited resolution
(1024x768, I think).
After a bit of googling, I found that the drivers for the Intel graphics on
this board (Rocket Lake, UHD 750) were not
included in the 5.10 kernel that came with Debian Bullseye. I installed kernel
5.14 from Debian Testing, and that seemed to
solve the issue - I got full resolution (still with a single monitor attached).
Taking the system into use as my main system, I set it up with two monitors,
one connected with an HDMI cable, one with a
DVI cable. (Both monitors are Benq 24 inch 1920x1080.)
Booting the system, it hangs during boot, with a message "VMC (outside TXT)
disabled by bios".
Booting the system with only the HDMI-connected monitor attached works as
expected, the system completes the boot sequence,
I can log in and use the system.
Attaching the second monitor after boot also works, both monitors are
recognized and works.
As a workaround, I tried enabling "Intel virtualization technology" in the
BIOS. Booting with both monitors attached, there
is no longer any error message, but the system still hangs during boot (with a
blank screen).
I would expect the system to boot also with two monitors attached.
