Hello @aplattner and @generix ,
I’m running on render offload mode (I suppose) and apparently I’m able to connect to an external monitor via HDMI, which by what I read it was not possible supposedly.
I don’t have a proper knowledge of the concepts behind all this matter of hybrid gpus, optimus stuff etc, and I’m a little confused by now. If you guys can elucidate me I would be much grateful.
At this point, I can be at nvidia profile via prime-select, and switch back to intel when I need (and in that case I’m not able to connect to the external monitor of course).
After installing cuda and cudNN successfully, everything is fine, running as it should (I suppose).
Now the problem is, after I upgrade the system by apt upgrade and reboot, which install the following packages:
distro-info-data gir1.2-json-1.0 gnome-software gnome-software-common
gnome-software-plugin-snap libjson-glib-1.0-0 libjson-glib-1.0-common
libpulse-mainloop-glib0 libpulse0 libpulsedsp pulseaudio
pulseaudio-module-bluetooth pulseaudio-utils python3-update-manager
ubuntu-software update-manager update-manager-core
the laptop monitor goes blank after login, only being with the external monitor working. (and even if the external is not plugged, the laptop screen is blank anyway)
Fortunately I had created a restore point before cuda installation and could get back.
Initially, I thought that was maybe the gnome packages that originate this and I marked them in order to not be upgraded, then upgrade the system but the same happened. So I think that maybe has to do with the xserver packages. What shall I do mates?
Still, about the possible modes that @aplattner said above, what is your advice of I should configure this system considering an amd/nvidia combo plus the fact I have to work with an external monitor, and be able to have the nvidia loaded for cuda? Should I change the actual setup considering that this problem of blank screen maybe happen in the future or the actual is ok?
The report before the upgrade is the following:

Thank you in advance guys.
