LinuxGizmos has an interesting article on how an Intel Engineer fixed up Linux's DisplayPort compliance, and got the kernel patch moved upstream.

At ELC 2017, Intel's Manasi Navare described how she patched Linux 4.12 for true DisplayPort compliance, and offered tips on pushing patches upstream.

If you've ever hooked up a Linux computer to a DisplayPort monitor and encountered only a flickering or blank screen, we've got good news for you. A graphics kernel developer at Intel's Open Source Technology Center has solved the problem with a patch that will go into Linux Kernel 4.12. Manasi Navare's patch modifies Atomic Kernel Mode Setting (KMS) technology to gracefully drop down to a lower resolution to display the image.

"Someone had to fix this problem, so I said okay, I have the knowledge and I have the community to help me," said Navare at the recent Embedded Linux Conference.

    When I got my nVidia 1070, Linux Mint for some reason couldn't pull up the proprietary drivers for it. Manually installed the drivers and it worked fine. Found an article recently to update it to the latest version and it now responds to the proprietary driver selection menus properly. It used to take years for Linux to get drivers for new hardware up to snuff. Now you have to wait a few weeks. If you have some patience it isn't a big deal getting bleeding edge hardware to work properly in Linux. (I don't use displayport though so ymmv)

    Well, when I say "hate the hell out of", I mean, "I had to manually install the proprietary driver". It's not something I've had to do in Linux for years. I'm toying with Sparky at the moment, which I believe is similar to Mint in the level of polish it has.

    It's still leaps and bounds better than where Windows is. Seriously, if it weren't for games...
