From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Linux in 5k? (feddit.nl)

My laptop has been having problems not charging and the top row of the keyboard stopped working. In my pursuit of a replacement I realized how ridiculously cheap Intel iMacs have become.

And then I realized that you can gut them and convert them into an insanely good computer monitor after the internals die.

I was looking for a dead one but somehow managed to get my hands on a working 5k 2017 iMac for $150. God the display is glorious.

For the time being Im just going to use the existing internals since they're still functioning.

I installed Fedora on an external drive and everything seems to be functional. I managed to get fractional scaling functioning. However the output only goes up to 4k. And while thats still really nice, the extra resolution does make an obvious difference when sitting ~1 foot away.

Has anyone been able to get 5k working?

Those 5k panels were goofy: they're two DisplayPort links merged via software magic into 5k.

Might be that's a proprietary thing that requires OS X?

I never got it to work at anything over 4k several years ago.

I went down the rabbit hole and ended up just selling. Apple only ever released the driver for macOS and for Windows 10 with Bootcamp.

Apparently it will work in X11 with a few setup changes per this thread: https://www.linuxquestions.org/questions/showthread.php?p=6477626#post6477626

Does that mean you weren't able to implement those changes or didn't want to regress back from Wayland?

That thread is just the result of a search today to see if the situation has changed.

When I tried it, we were still trying to figure out how the two displays worked. It looks like that link has a solution. It would have been great to try back then, but I wouldn't go out and buy a 5k iMac or LG monitor just to try it out now.

i have a 2017 lg 5k monitor (same goofy software trick) that works with ubuntu x11

It depends on the displayport version. DP 1.2 only supports 4k. DP 1.4 supports more. So if it's an older display that only supports DP 1.2, you have to use the two screens hack. I never tried that, though.

What does the display setting look like? Can you just set the resolution manually
