Worked like a charm: no waiting for enough entropy to be collected. No problem. What's weird is that bug is known to affect kernels 4.16.x but all my machines use 4.14.x. Out of eight machines only one of them had this problem, which is even more strange. It does happen to be the oldest machine, though. That laptop has had slow boots, but not necessarily Xorg, for a long time and I could never figure it out. I even installed an SSD thinking it could've been the HDD in it a couple years ago; that's how long the slow booting has happened. Never occured to me the random number generator could cause that.

If you'd read the part you snipped, you'd have seen that Dan had indeed tried haveged and it worked. Thank you, Dan. I hadn't heard of it, but your report immediately suggested I try it to reduce the wait while chronyd started, on two machines here. Worked like a charm: no waiting for enough entropy to be collected. -- Regards, Peter.

You could install sys-apps/haveged. I really don't know if this will solve your actual problem, but maybe it helps to speed up the random generation. -- wabe

I left the laptop sitting without logging in and when I came back ten minutes later I saw that Xorg started. I found this in the log: [ 298.914537] random: crng init done [ 298.914542] random: 5 urandom warning(s) missed due to ratelimiting So about five minutes after boot the random number finished initializing and the Xorg started right after. After googling around I found a problem in kernels 4.16 that had this type of problem but: 4.14.78-gentoo I waded through results some more and found other having success installing haveged and setting it to start on boot... so I tried it and now the laptop boots normally! Weird. I guess it's solved? Dan
