<p>I was able to ssh -XY into a Rocky 9 (RHEL 9) system, run
chimerax, have it display on my local system and the GUI works.
So it can work. So there is something incompatible between
your two systems that you need to figure out. I'd recommend
eliminating the graphics driver being incompatible issue by using
VirtualGL. And if that doesn't fix it, use your daily build on
RHEL 7, to file a bug. And describe the problem in the
Description section. You should also include information about
the remote system, specifically to the OS and version, and which
graphics card it has and the driver version.<br>

<div>Hi Greg,</div>

<div>Thank you so much for your detailed explanation! <br>

<div>I tried ChimeraX 1.4 (both the latest stable release and
daily build) on RHEL 8.1, 8.6, and 9.0, because it can only be
installed on RHEL 8 or 9. They all had the same problem
(frozen after launching the GUI).</div>
<div><br>
</div>
<div>I also had an old daily build (04/12/2022) of version 1.4,
which allowed me to install it on RHEL7.9, but not RHEL 8 or
9. I'm running v1.4 (04/12/2022) on RHEL7.9 now because the
helix cylinder functionality is only available in v1.4.<br>

<p>ChimeraX was compiled on "CentOS Linux release 8.5.2111",
but that is extremely unlikely to matter.<br>
</p>
<p>The main GUI change between ChimeraX 1.4 and 1.3 is that
ChimeraX 1.3 uses Qt 5 and ChimeraX 1.4 uses Qt 6. So,
from your original description, the most likely bug is
that we missed a dependency that is needed for Qt 6 to
work. So you should try installing Qt 6 separately from <a
href="https://www.qt.io/download" target="_blank"
moz-do-not-send="true" class="moz-txt-link-freetext">https://www.qt.io/download</a>
(eg., get the open source version's Qt Online Installer),
and see if that fixes the problem.<br>
</p>
<p>But you also mention trying to run ChimeraX by logging
into a remote system running RHEL 8.6 from RHEL 7.9.
Running ChimeraX remotely frequently fails to work.
Officially, that is not supported. There are too many
possible points of failure. It does work sometimes, and
especially when the local and remote system are running
the exact same version of Linux and have the exact same
graphics driver installed. The graphics driver is the
usual culprit, and that can be mitigated by running
ChimeraX under VirtualGL on the remote system.</p>
<p>For completeness, if you are stuck with a RHEL 7 desktop,
and your data is on your local system, you could run
ChimeraX in a virtual machine. So instead of logging in
via ssh, you startup the virtual machine, and login to it
directly. Some virtual machines are better than others.
I've been happy running different flavors of Linux on
VMware Workstation Player on a Windows desktop with a
Nvidia GeForce GTX 970 (remember to enable 3D graphics
support). There is also a Linux version of VMware
Workstation Player.<br>

<div>Dear ChimeraX developers,</div>
<div><br>
</div>
<div>I installed ChimeraX 1.4 (both stable release
and daily built) on RHEL 8.6 and 9.0. <br>
</div>
<div><br>
</div>
<div>I installed all the ChimeraX 1.4 dependencies
using "yum install" from RHEL installation USB.<br>
</div>
<div><br>
</div>
<div>After the installation, I was able to start the
GUI, but unable to click any button on the GUI,
therefore, I was unable to report the bug from the
GUI either.<br>
</div>
<div><br>
</div>
<div>I also tried ChimeraX 1.3 stable release on
RHEL 8.6, and everything was normal.</div>
