When my laptop is in sleep mode and I press Enter to wake it up it takes 5-10 seconds to show the lock screen (I sometimes see a rectangle tty-like cursor while it’s loading) and another 3 to update the time from what was the last time when it went to sleep to the current time. I have a relatively modern laptop—Windows took 1-2 seconds for the same thing. Is it a normal delay?
It also randomly wakes up every 30 minutes or so when the lid is up (pretty annoying at night), but I also had this problem with Windows so I guess that’s a hardware issue.
