I installed Ubuntu 18.04 on my Dell Inspiron 13 ( Tried an upgrade from 16.04, didn’t succeed, then reinstalled without data loss )
Here is what happens –
Switch on / Login to Gnome ( x11 ) with an external monitor attached > gnome becomes unresponsive
( Some time extensions are working fine since i can system monitor graphs scrolling, but mouse clicks and keyboard wont work )
Potential Culprits –
- Multi monitor add on
- Gnome itself
The only way that works –
Login without external monitor attached > disable multi monitor add on > attach external monitor > enable add on
this made me think the add on is at fault. But here is another scenario in which Gnome hangs –
Add on is disabled, fresh boot > login with external monitor attached > gnome unresponsive
Has anyone else faced this? What could be the potential issue / potential debugging steps?
No graphics card in picture
Its literally frustrating!
