I changed the logo named ubuntu-logo.png under /usr/share/plymouth

But, it reverts to the original logo (please click/tap on the "Image" for reference) after I rebooted my system.

GDM Background is not compatible with my system, Ubuntu 22.04 either to resolve my issue.

  • could you write the output of /usr/share/plymouth/plymouthd.defaults? It may be using a theme – Amirreza Oct 27 '22 at 15:15
  • Do you mean /usr/share/plymouth/ubuntu-logo.png? It's the default logo which we can see on the above link named "Image" – Linux Kid Inside Oct 27 '22 at 15:55
  • I hope updating grub helps – Amirreza Oct 27 '22 at 16:41
  • I'm not pertaining to GRUB2 but to the login screen logo where you can input your password to access the Desktop – Linux Kid Inside Oct 27 '22 at 17:19
  • my bad, I was explaining boot splash screen, hope this link helps https://askubuntu.com/questions/1227070/how-do-i-change-login-screen-theme-or-background-in-ubuntu-20-04 – Amirreza Oct 28 '22 at 07:58
  • No worries, anyway, the link you provided is not applicable for 22.04 and I tried the other option already which is the GDM Background link above that doesn't work either. I appreciate your effort. – Linux Kid Inside Oct 28 '22 at 11:55
  • plymouth is only for boot screens, it will not affect the login screen. For that you need to make a custom GDM theme, probably. Or check out https://help.gnome.org/admin/system-admin-guide/stable/login-logo.html.en not sure if it still is relevant for newer versions, but it may be – Esther Nov 29 '22 at 01:01
