Having multiple accounts logged in at once makes my laptop very slow and crashes

I am an Ubuntu user, and I decided to manage my laptop to use two accounts: one for personal use, and the other for work. If I switch accounts from one to other without terminating the session, the system is very slow and unresponsive, often forcing me to restart the machine. This seems very odd to me because the laptop has very good specs in terms of CPU and memory. How can I prevent this and be able to freely switch accounts without having to deal with the inconvenience of reopening all tabs and programs every time I come on and off work?

Can you include the output of `free -m` in your question?

@vidarlo At what point should I include it? If it's right before the freese I find it quite difficult to get any output with my current knowledge.

Done, I added a couple of misuration: one at the start, and some others after opening my usual work apps (Firefox, VSCode)

Read `man free`. `free -h` will show how much RAM and swap you have, in `h`uman readable format

You could use `ps -ef` to see ALL processes. Read `man ps`.

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.
