[04:32] <diogenes_> TiZ: do you have 'session save' enabled?
[04:39] <ZackWard> Hello, someone can tell mne the difference between package xubuntu-core and xubuntu-core^
[04:39] <ZackWard> i mean with and without the carret
[07:40] <dreamon> diogenes_, hello. I ask you months ago, what could be reason I cannot login in after suspend. I see no login screen but I can see xfce without reacting. After typing password it go on working like it should. Now I found the reason, I want to share with you. might be you no a solution..
[10:04] <diogenes_> dreamon: so what was the reason?
[10:32] <dreamon> diogenes_, I use a thinkpad thats connected to usb-c thunderbold, dockingstation. xubuntu uses my second screen, too. by use standby and plugoff notebook. and restart from stdby I have this issue. cause he think external monitor is still connected. but it isnt.
[10:34] <dreamon> If notebook is plugged in again, using arandr an disable second monitor. standby, plugoff, reboot it works normally. 
[10:35] <dreamon> I think that change is not recognized correct at reboot. Login screen might be visible on not existing screen to login.
[10:41] <diogenes_> dreamon: ah all this mess with multiple monitor that lightdm still can't do properly.
[10:44] <dreamon> diogenes_, Im not sure if its only a lightdm issue. I had some strange horizontal strips by scrolling vertical. Now I know I can solve this by starting arandr and disable second screen. cause its not attached but is show as second screen.
[10:45] <dreamon> sorry my bad englisch.
[10:47] <dreamon> this only happens on my usb-c plugged in monitor. using same monitor an plugg it on hdmi to the laptop, no issue. unplug and its not visible in arandr. not by usb-c still there..
