Package: general Severity: important X-Debbugs-Cc: gaff...@live.com 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.
