I have a mid 2010 Macbook with the Nvidia GeForce 320m. Getting elementary to boot, and subsequently work well with this graphics card has required several adjustments, but I've gotten to a pretty stable place where I can run the Nvidia 340 graphics driver for simple gaming/graphics and resolution of overheating issues.
My issue though, is that suspending and subsequently resuming doesn't seem to work. I did not have this issue with the open-source drivers. After suspending, when I try to use the computer again, the screen is completely black and doesn't even have a backlight. I've noticed that Ubuntu has no trouble resuming however, so I installed GDM3 and found that I can resume okay using GDM3 as my display manager.
My question is: is there something I can do to make resuming function okay with LightDM? I imagine this is an Xorg config issue, but I'm not sure.
Thanks in advance.
