  11. 			<p><strong>2022-05 note</strong>: It's getting really rare for something to not work unless it's stuck to X11 or it's badly linking to OpenGL, consider that most things "Just Works", unless I described a problem and it's still there.</p>
  12. 			<p>
  13. 				<strong>Warning:</strong> This is Wayland without any of <code>libX11</code> or related (ie. <code>libGL.so</code> instead of <code>libOpenGL.so</code>) in the system, this also removes the <code>XWayland</code> compatibility layer as it's an xorg-server component.<br/>
  14. 				You can find this kind of similar setup in embedded systems (ie. SailfishOS), as X11 makes no sense outside of keyboard+mouse setups, but I don't expect it until a bunch of years for regular desktops (say when X.Org will have died), I'm doing this right now to avoid having to rush to get rid of X11 with having to push the End-of-Life date way back it's upstream date (that happened with python-2 because it wasn't much prepared until the last year or two).<br/>
  15. 				It's also the kind of setup that I expect soon in security-oriented systems because Wayland addresses a number of design flaws.
  16. 			</p>
  17. 			<p>Testing is done on Gentoo Linux with <code>USE="-X -XWayland"</code> and <del><code><kbd>-DEGL_NO_X11</kbd></code> into the <code>C(XX)FLAGS</code></del>(fixed via <a href="https://gitlab.freedesktop.org/glvnd/libglvnd/-/merge_requests/246">patching libglvnd</a>). And launched into the <a href="https://swaywm.org">Sway compositor</a>.</p>

  27. 			<p>Do not ask Libre software developers for support of the NVidia proprietary driver, specially when they already refused, the driver being proprietary means that any bug found has to be worked around, which often isn't possible without compromising performance and stability.</p>
  28. 			<p>Also, in terms of history:</p>
  29. 			<ul>
  30. 				<li>After almost 10 years NVidia has yet to provide a complete enough driver for Wayland</li>
  31. 				<li><del>Instead of providing the GBM API like everyone else, including other proprietary drivers (there is a lot of them on the embedded side of things), they created EGLStreams, which means a very large chunk of code (and so bugs) specific to NVidia</del></li>
  32. 				<li>Contributes to a huge waste of chips by stopping the support of GPUs after about 5 years</li>
  33. 				<li><del>Has basically been trashing any hope for nouveau to be a complete driver (check FOSDEM videos of the nouveau developers)</del></li>
  34. 				<li>NVidia performance vs. AMDGPU performance on linux doesn't have a very large gap on real-life loads</li>
  35. 				<li><a href="https://forums.developer.nvidia.com/t/support-for-async-reprojection/123382">Doesn't provides async reprojection on linux, so no VR for you</a> (Or a lot of those nice Vulkan speedups)</li>
  36. 				<li><a href="https://en.wikipedia.org/wiki/Nvidia_Optimus#Linux_support">Remember how awful Nvidia Optimus is?</a></li>
  37. 				<li>Video decoder driver can have frequent glitches depending on the encoding</li>

  42. 			<h3>CMake</h3>
  43. 			<ol>
  44. 				<li>Replace <code>find_package(OpenGL REQUIRED)</code> to something like <code>find_package(OpenGL COMPONENTS OpenGL REQUIRED)</code>. This allows to not error out when libGL.so isn't found but libOpenGL.so is.</li>
  45. 				<li>Replace <code>OPENGL_gl_LIBRARY</code> to <code>OPENGL_opengl_LIBRARY</code>. This will allow to use libOpenGL.so over libGL.so when possible.</li>
  46. 			</ol>
  47. 			<h3>Auto*hell</h3>
