[23:29] <guiverc> I rebooted last night & thus seem to have lost two displays.  On boot plymouth shows on 5 (3 via intel, 2 via amd/radeon) then when DM (sddm) shows I get only 3 (intel) which is normal. At login normal behavior is i get all 5 (intelx3+radeonx2) but since reboot last night I'm not seeing radeon except during boot/plymouth.  Reboot & booting into jammy (box is dualboot) is normal; all displays work at login.  (same response in Lubuntu/LXQt or 
[23:29] <guiverc> Ubuntu/GNOME, didn't try Xubuntu/Xfce)  Any clues appreciated
