Edit: I don't why everyone's having issues. I run Fedora on a cheap Gigabyte G5KD and never had any problems. Never did with either of my thinkpads or my Xiaomi Mi Notebook...
Yeah right. Suspend and resume is still buggy as hell. Power management in general in Linux is still awful after all these years.
Most PC are delivered with Windows, and even though Linux works on them, it's unlikely the PC were designed with suspend stability as criteria.
For years I use suspend on my laptop with latest Debian, and it's very difficult to have an uptime higher than 15 days.
Every now and then, the logging in freezes to death on wake-up and requires hard power off.
Nobody is paying for Linux on average PC hardware, that's why 20 year old bugs are not fixed.
Over the last 5 years, I had about 4 laptops that I ran Linux on. Not a single one was able to survive this:
- Do some work on it - Close the lid - Drive somewhere else - Resume work
At best, the laptop would freeze and require a hard reset (extra annoying on Dell XPS for some reason). At worst, it will be completely draining of power. All of my linux-loving colleges had the same issues. Windows worked just fine on those laptops, btw.
If you're curious, we've advanced beyond simple Suspend-to-RAM in 2012 when haswell was released. Out of the 3 major OS that used on desktop, only linux doesn't support those features: https://www.anandtech.com/show/6355/intels-haswell-architect...
I rarely have issues with S3 on my linux/windows desktop, though.
No.
I have an old Dell laptop that still doesn't power off when asked from Ubuntu Desktop. Always reboots instead.
