However, if I don't suspend manually before closing the lid, on system resume it seems like I get logged out of my X session. ยท I have been running different versions of Ubuntu on 2 different systems myself: __ Machine _______| Version | DE ___| GPUs _______| Display | prop. driver 1) ThinkPad E530 _- 16.04 __- Unity - Intel _________- Xorg - no 2) ThinkPad E530 _- 16.04 __- Gnome - Intel _________- Xorg - no 3) ThinkPad T470p - 17.10 __- Gnome - Intel + Nvidia - Xorg - no 4) ThinkPad T470p - 18.04 __- Gnome - Intel + Nvidia - Xorg - yes and this is the first time (configuration #4) that the problem presents itself.
