# No 3d graphics with sage 9.8 using conda-forge

I have a problem with an installation of sage-9.8 using conda-forge on Ubuntu 23.04. Following the installation guide for a complete installation I can run sage successfully. 2d graphics work, the png viewer launches, but trying an example using plot3d, nothing happens---that is sage replies it has lanuched the viewer but neither the web browser nor the jmol applet launches.

```
(base) rquint@LunarBox:~$ mamba activate sage
(sage) rquint@LunarBox:~$ sage

sage: exit

```

Is there something else to install? If so, what are the requisite commands? (Thanks @slelievre for how to include code blocks.)

To display code blocks properly, indent them by four spaces.

The solutions using alternative settings for TMPDIR and DOT_SAGE or a non-snap browser have all worked with installations of sage-9.8 built from source. There's something else going on with my installation using conda-forge. the jmol viewer worked straight out of the box with the installation build from source, but it doesn't with the conda-forge install. I'll try again as soon as sage-10 is out, but for now I have wiped the conda-forge install and have gone back to building from source.

Sorry, I forgot to address the jmol part of the question. I can also confirm it fails for me.

Even with TMPDIR set to

`~/tmp`

, plotting with jmol fails for me in conda-installed Sage 9.8.
