How can I change the Ubuntu 20.04 login screen theme or background?
In the previous version 19.10, I can change it from the CSS file under Yaru theme but now there is no CSS file.
On Ubuntu 18.04, I have connected my laptop to an external display and I am able to set the external display as primary and external display only mode. But when I turn on my laptop or log out from my session the display login screen is displayed only on my(internal) laptop screen. But once I login the display switches to external only and my laptop screen turns off as expected.
Is there a way I can make the login screen appear only on the external screen on bootup or on logout as in 16.04? Also the login screen does not follow my cursor as in 16.04.
I have hard a hard time finding good information on the performance difference between display managers on Ubuntu (specifically between lightdm and gdm3).
With Ubuntu switching to Gnome, I would assume that it would also be recommended to switch to gdm3 instead of lightdm but I can't find any information one way or the other.
So:
- Is this the case? Will
lightdmstill be developed? - Is
lightdmfaster thangdm3? (Answers like this saylightdmis "lightweight and fast" but do not say whether or notgdm3is slow....)
After upgrading to 17.10 like a true pioneer, I found the old CtrlAltF1 no longer switches between console mode and GUI, and a quick Google search brought up nothing useful. Was this feature removed entirely?
I have recently added several new users, that I need for qmail. Now they appear in the box in the login screen and clutter it, and I have to scroll to find my user. How can I hide those users from the login box?
