Thanks for the advice. Unfortunately I don't completely understand what you mean with the following:
> Of course if some non trusted packages has also been installed, then goto ubuntu archive. For the moment I have purged xserver-xorg-video-intel without reinstalling it (since I've seen that it is optional). I cannot yet verify with certainty whether this solves the issue because I haven't found a way to reproduce it in a deterministic way. That said, after uninstalling xserver-xorg-video-intel, my virtual terminals are visible again (which I hadn't mentioned in the original post because I hadn't thought that this issue might be related). I will keep this configuration until I either run into the original issue again or you advice me to install the package again. In case this was a misconfiguration on my side (don't know why the optional package was installed): Sorry for filing a bug report.
