How to replace login screen system

cn flag

I'm having issues with my the default ubuntu login system, because

  • It takes FOREVER to load when I close and open my laptop
  • It often doesn't load correctly, the dock icons are missing and opening the applications menu makes ubuntu unusable, so i gotta kill my pc with the power button
  • Sometimes I enter the password, it loads for a long time, screen goes black, and then i'm back at the login screen
  • Sometimes it just refuses to load after I close and open my laptop, it only shows a black screen I'm not interested in changing the theme or the background image, I wanna change the entire mechanism behind the login screen because it's been nothing but a pain ever since I installed ubuntu. (these issues happen with me in 20 LTS, 21.04 and 21.10) Reinstalling doesn't help either. Please help!

Have you tried a different desktop environment? Different flavours of Ubuntu use different greeters and flavours like Lubuntu and Xubuntu are much lighter than others.

Edit your question and show me `free -h` and `sysctl vm.swappiness` and `ls -al /var/crash` and `sudo dmidecode -s bios-version`. What EXACT make/model laptop? Which CPU? What video card and driver version? Start comments to me with @heynnema or I'll miss them.

Ubuntu Core 20 doesn't have a login/greeter (20 != 20.04 and 20 is intended application is headless so it makes no sense); for 21.04 & 21.10 desktop systems that's `gdm3` by default - which is easily replaced; but that likely won't change much - just the way the login look to me (ie. I don't believe it's your issue; as `gdm3` is a cut down GNOME using services GNOME requires running on login, so using another won't help login time; just change the way the login looks/works)

Does this answer your question? [Ubuntu gets stuck in a login loop](

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.
