I found the same bug. This is my graphic card (but I'm not sure how to check the driver version): Video Card: NVIDIA Corporation GM206 [GeForce GTX 960] (rev a1) OS version: Ubuntu 16.04.2 LTS
I think that those "funny" colors space is the video card memory that wasn't refreshed. Maybe during the suspend it got some noise values and it should be fixed with a 'redraw' call. But I'm no expert on Ubuntu or video card code :P -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1668465 Title: weird color display after suspend.
