We have
decided on setting up <a href="https://chimera-linux.org/">Chimera Linux</a>.  Since Chimera Linux is new, we also installed the guix package manager as well.  This blog post today is more of documentation and less story telling.  You have been warned.</p><h1>upgrading chimera linux</h1><pre><code>doas apk update

doas apk upgrade</code></pre><h1>DONE Getting X applications and gdm to run on chimera</h1><p>All Talos II machines have trouble running X, when a discrete GPU is installed.
Basically the Talos II has an on board GPU, which when combined with an AMD GPU,
X does not know which GPU to use. <a href="https://wiki.raptorcs.com/wiki/Troubleshooting/GPU#Xorg_will_not_start_.2F_crashes_when_a_discrete_GPU_is_installed">click here</a> to read more on the raptor wiki.</p><p>I did have trouble getting my friend’s Talos II to start gdm and X, but an
update to chimera linux fixed the gdm issue.  The below sections are for others
that are using a Talos II with an AMD GPU.  You do need to configure X to
disable the onboard GPU and/or tell GDM to select a GPU at runtime.</p><h2>raptor pdf user’s guide:</h2><p><a href="https://wiki.raptorcs.com/w/images/e/e3/T2P9D01_users_guide_version_1_0.pdf">https://wiki.raptorcs.com/w/images/e/e3/T2P9D01_users_guide_version_1_0.pdf</a></p><h3>raptor wiki ways to fix this</h3><ol><li>Tell GDM to ignore a GPU</li></ol><p>In this case ignore the crappy onboard GPU.</p><pre><code>    lspci | grep VGA
