envycontrol VS xrdp

You're probably looking for envycontrol ... it will allow you to switch back and forth between integrated/hybrid/dedicated-only graphics as needed. I used this on my 2023 Legion Slim 5 and it made a huge difference in power consumption. Now I only enable dedicated if I need it for something specific, which is rare for me. Computer generally sips between 16w-20w doing basic browsing tasks, with no other optimizations performed (this is on Fedora Silverblue)

Install EnvyControl, which is a useful package that can offload applications to the integrated GPU and turn off the dedicated Nvidia GPU. This will add a few hours at least to your battery life. Distro-specific instructions: https://github.com/bayasdev/envycontrol

Check out this video. https://youtu.be/Pn2iUgW3l6w . It's how I setup my graphics card. You could also use envy control https://github.com/bayasdev/envycontrol.

Now, it's much easier to enable the Fusion repository and Envycontrol makes it as easy as Ubuntu to switch GPUs! I also use DisplayLink for additional monitors and there is now a 3rd party rpm for that.

use envycontrol

I thus played a bit with https://github.com/bayasdev/envycontrol which is listed on the archwiiki, the problem is that now, even when selecting the "nvidia" mode and even when going back to "discret graphics" in the bios I'm encountering bugs I didn't have before, mainly SDDM being really zoomed, i3 borders being HUGE (while the rest is normal, I didn't change my config so it's likely not a DPI problem there), glitches when I first login with polybar duplicating itself and the wallpaper being broken, requiring to refresh i3 to have those 2 things fixes, picom animations are also super glitchy.

xrdp

Or maybe it could be done through xrdp somehow?

Part of the reason that RDP isn't better is because it's not an open protocol, part of the reason is because the protocol was built to present a desktop environment that isn't remotely like xorg or Wayland. A lot of the reason is that the RDP project just doesn't get enough effort, because people have multiple ways of sharing desktops, and RDP is just one of them. If you would like to fix that, here's the (currently) 274 open bugs against the Linux attempt to implement RDP https://github.com/neutrinolabs/xrdp/issues

Check out xrdp. You can connect then via any rdp client.

If you're willing to compile there are patches to xrdp to include some performance improvements that make a huge difference (more modern codecs). Tracking issue with instructions is here https://github.com/neutrinolabs/xrdp/issues/1422 it's quite long, so I'd start reading closer to the bottom. Performance has been really good in my testing.

This may help. https://github.com/neutrinolabs/xrdp/issues/2034

Indeed, this was... 2002? or so (xrdp)[http://www.xrdp.org/] was still not available.

So... just use Remote Desktop. A popular open source version of RDP is XRDP, which is packaged and available for installation on most popular distributions. Just install it, let it start up the xrdp service, and then connect to it just like it was a Windows server. That's it.
