hum it is strange… I previously installed bookworm on the same laptop a
while ago (12.3 if I remember correctly) and it did work (both minitors)
until I installed proprietary nvidia drivers and the computer froze (or
just got black screens) when returning from suspend and I got tired of it…

Anyway thanks for your help, I might follow on your suggestion and update
to trixie as it should become quite usable now it is almost time for a
release :)

Thanks

Brieuc
