Hi, I have a HP g6 laptop. When resuming from suspend it’s exhibiting problematic results as the display is garbled and switching between TTY2,TTY3,TTY4 (not necessarily in that order). This is required to achieve a usable SDDM login Display Manager. Sometimes these steps are unable to grab (from any TTY), a usable SDDM login screen. Must then close laptop lid… let machine suspend and open lid, and then reattempt the process described above.
Once able to grab a usable SDDM window, SDDM will then have a different background, (the desktop background). Not the set background initially displayed when machine is initially booted to SDDM.
Passing # systemctl restart sddm.service seems to help greatly, correct SDDM background is then also displayed. After then switching around TTY’s.
This occurs with X11 and Wayland.
