Running slow from boot to shutdown

I got a new computer custom built but with Windows installed about a year ago. I installed Ubuntu for dual boot with grub. It has i7-8700 cpu with 12 cores and 32 Gb RAM.

Generally speaking, it ran fine most of the time but a couple months ago it started running very slowly. I had hoped the 21.10 update would clear it up, but no luck. I have also had it start completely crashing periodically. Windows appears still to work fine.

I have searched for help but everything is either very basic (check RAM usage) or very specific (failure X is causing slow booting at this time stamp). I keep the system monitor open as I work and my RAM usage is often below 20% with 0% swap used. All 12 cores show negligible use and the fans are at normal speed.

Even so, I have boots lasting upwards of 20 minutes if it doesn’t hang. I had a shutdown lasting over 10 minutes just now before I decided to go home because I need to get work done. Simple tasks like selecting an active window or switching virtual desktops often takes many seconds and keyboard input is just as bad.

Do I just need a complete reinstall action? Anyone have any suggestions about how to diagnose the issue?

Start with your logs. /var/log/syslog and journalctl.

Also, `systemd-analyze blame`. `sudo journalctl -b 0` will show you logs starting at the most recent boot.

@waltinator I am not sure how to interpret the results of journalctl but they systemd-analyze blame command tells me that bootup is not yet finished. It suggests to use systemctl list-jobs, which tells me that apport-autoreport.service is running the start type.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
