Okay, I now know what *probably* have happened. My proprietary motherboard - MSI PC Mate B350 tricked me - after updating the firmware and enabling the "UEFI mode" instead of "UEFI or legacy BIOS" I got a higher resolution and network started to work normally. Before enabling it, the GUI installer couldn't find network connection itself, so I had to manually configure network connection by using ifconfig and dhclient, then I just followed the GUI installer, and it somehow let me continue with or without networking. Tried switching back to BIOS mode, but I can't reproduce the bug anymore. None of this happens on my librebooted machine, tried hard to break the installation :). Guess that's it, thanks for your time. I'm probably going to sell this nonfree machine anyway. Jan
