I had similar issues, randomly: - black screen after waking up - unresponsive terminal (keyboard and touchpad were responding but commands were not executed, CTRL+C didn't work, no network). - something that looked like crashed X Window server (went back to the console) - and mix of issues above
Started a few days ago, worked perfectly fine previously. I updated to latest snapshot and I could still reproduce all issues. Then I built kernel HEAD (~2h ago). And it's just fine now. I tried really hard and I'm unable to crash the machine (it's not Lenovo, it's Matebook X). -- Krystian
