I have a PC I built about a year ago, it's been working fine without issues, and suspend/resume from suspend has always worked great. Just in the last week or so though suspend functionality broke. In the past when I suspended my PC, the power light would eventually turn off. Then in the future I could hit my keyboard or hit the power button once and the computer would turn back on and resume where it was. Now, however, when I try to suspend, the screen goes black, but the power button never turns off. If I hit a keyboard key or the power button again, nothing happens. The only way forward is to hold down the power button until the computer forcibly turns off.
I suspect this broke when I did a recent software update - I hadn't run any updates in a few weeks so last week when I ran software updates there were a lot of packages that needed updating, including some core linux/ubuntu packages, though of course I don't remember the specific names or packages involved.
