<p>There is a bug in the instructions for the release candidate, it
should say to "sudo apt install ~/Downloads/chimerax-rc.deb". Not
ucsf-chimerax_1.5+rc2022.11.09ubuntu22.04_amd64.deb. Does that
explain the problem you had installing ChimeraX? If not, I'd like
to learn more so I can fix it.<br>
</p>

<p>ChimeraX does not work well with the open source Nvidia driver on
Linux. You need to install the proprietary Nvidia driver.</p>
<p>And make sure the the display cable is plugged into the Nvidia
graphics card instead of the integrated graphics. See
<a class="moz-txt-link-freetext" href="https://linuxconfig.org/how-to-install-the-nvidia-drivers-on-ubuntu-20-04-focal-fossa-linux">https://linuxconfig.org/how-to-install-the-nvidia-drivers-on-ubuntu-20-04-focal-fossa-linux</a>
for the various ways to choose which Nvidia driver to install on
Ubuntu.<br>
</p>
<p><br>
</p>
<p>Right now there are way too many Nvidia driver to choose from.
That is because there is a completely open source driver, several
combination open source and proprietary drivers, and several
proprietary drivers available. Today, those choices are a subset
of:<br>

Your exact choices depend on your graphics card. Stay way from
the nouveau, -open, and -server versions. We're using the 470
driver on a GeForce RTX 3070. The 515 and 520 versions didn't
work correctly with ChimeraX when we made our choice months ago.
I expect that has changed and that the 515 and 520 drivers are
fine now, but maybe not. Within a year, I expect that the -open
drivers will completely replace the non-open ones, but that time
is not now.</p>

I recently installed a Nvidia RTX Titan GPU card, and ChimeraX
1.5rc, it is a bit wired. I can open the window using
intergrated GPU but if I just clicked on Chimerax or try to open
it in terminal, it failed to open the program...</div>

Is ChimeraX only working on integrated GPU? Also, I cannot
install the chimerax using apt install as in the website
description, but dpkg -i works... is this the right way to
install?</div>
