It is fast - that was the first thing I noticed as well. About 1/2 an hour later the screen went black and the machine stopped responding to key presses. Eventually I resurrected by flipping to a text console and back, (Ctrl-Alt-F1, Crtl-Alt-F7). It turned out it was putting itself to sleep. After a few minutes. While on AC. And my fart arsing about wasn't fixing the problem - it was just soaking up time while X took its own sweet time to wake up (the text consoles were available immediately). And then this happened on other laptops I installed it on. Fixing it by disabling suspend when on AC is a nightmare. Every program + it's dog seems to have had a go at setting it - xscrensaver, window managers, display managers, X itself and systemd. Which one wins (ie the one you have to use to fix it, because it set it last) is a lottery. Maybe they can put fixing that mess on the list for bullseye.
