I wish I could use Linux but a very trivial task of "keep my second screen usable when I close my laptop lid" is apparently too much to ask :( OK, I have a discreet GPU, bit still!! Tried 5 different distros with different window managers, the closest I got was yes you van have the second screen but everything happens with on it with 5 second lag and at 1 FPS

For what it's worth, I have a lenovo thinkpad and this behavior was somehow baked into it for both windows and linux (ubuntu).

I had a weird experience in that the second screen(s) (connected via a USB dock) would be laggy if the chosen 'primary' monitor was not the one directly connected to the computer (either built-in monitor for a laptop, or directly connected via HDMI / DisplayPort). If the primary monitor was one of the two connected to the dock, they would be horribly laggy. That problem seems to have gone away, but I've changed machines and Linux distributions since then. I think it was with Ubuntu and using a Toshiba Dynadock.

> the closest I got was yes you van have the second screen but everything happens with on it with 5 second lag and at 1 FPS Used to happen on my nvidia laptop, you can try filing a complaint. One possible solution is to set the GPU to performance mode in Nvidia XServer settings.

I know there's settings for suspending in logind.conf and also in dconf, but no idea what controls what happens when you close the lid and do nothing, I use my old laptop exclusively through a screen sharing program that keeps the screen off, and it works fine, so it might actually be the graphics driver. If it's just the CPU scheduler being changed, you could always figure out a way to run your own command when the lid closes, to revert the changes to the way you like it a few seconds after the lid closes. https://askubuntu.com/a/1140362 https://askubuntu.com/a/1140362
