That seems like either a Ubuntu misconfiguration or buggy drivers when interacting with your hardware, but I certainly wouldn't say it's a "Linux" thing, may be a disto thing, Ubuntu's not known for caring much about the desktop these days. I have been using Linux successfully for more than a decade without such issues, which does not mean it didn't happen to you, but it does mean it's anecdotal. I am on a rolling-release disto, which updates much more frequently than Ubuntu does and yet, I've been able to continually upgrade a single install for the past 3 years without issue.
It's also nowhere near as bad as actually loosing data, as you mentioned.
I have also been using linux for over a decade and I still can't recommend it to any non-developers friends unless their hardware build is extremely common.
I am currently running two nvidia gtx 1080 SLI and multiple 4k monitors. Even for just installing the OS, I need to physically remove both graphic cards and use a smaller monitor first. This physically laborious workaround just to reinstall the damn thing is what amplified my rage when it decided to break on autoupdate.
