I tried disabling the integrated graphics card in the BIOS a few weeks / months ago but it did not change anything.
Today I moved the Nvidia card to another PCI slot and it seems to be working fine. I have not experienced any freeze so far. It might be a little soon, but for now, I can only assume your first guess was correct and it is a hardware issue. The PCI slot the Nvidia card was in before might be faulty. The motherboard is still under warranty but I am not sure I will manage to prove to the store that sold it to me, that this very PCI slot is faulty because of the randomness of the freezes, when using a specific display server under linux... (Everything works fine under Windows or a X11 session, even rather heavy gaming.) Again, thank you a lot Daniel! And please excuse me for taking up your valuable time. I would not have been able to isolate the issue without your help.
