NX Quick Start Guide
Here are the instructions for accessing beamline 8-ID workstations:
1. Login to the NoMachine Portal here: https://delos.aps.anl.gov (use your DM credentials "d<badge>/esaf password" ; Argonne users can use their ANL LDAP username/password)
2. Select the system you want to connect to, and click the Connect button.
- 8-ID-E pepper
- 8-ID-I quartz
3. Select the existing virtual desktop to run the instrument.
- XPCS at 8-ID-I : 8idiuser
- WA-XPCS at 8-ID-E: 8ideuser
- GIXS at 8-ID-E : 8idguser (client Pepper)
4. Click Continue button.
At this point, you should be at a Gnome desktop where you can open applications. If you are presented with a message “Waiting for the desktop user to authorize your connection” then your setup for access to the session is not complete. Consult with your beamline contact to correct this.
You can adjust display settings in the Display settings panel, which you can access by clicking the "peel back" in the upper right corner. NX desktops run better with more network bandwidth. The default settings should be fine for most connections. In some cases however, you may have to make adjustments. For example, on a 15Mbps connection, you may have to lower the Quality level slider to get the desktop to run smooth.
Verifying/updating APS Web Account
All experimenters on APS Proposal or ESAF should have created an account through the APS Web Portal athttps://beam.aps.anl.gov/pls/apsweb/usercheckin.start_page. If the user does not have a badge number, they will need to register with the APS User Office at https://beam.aps.anl.gov/pls/apsweb/ufr_main_pkg.usr_start_page. To verify or update the Web Password, users can try to log into the web portal above. Like other web accounts, it is possible to update an unknown/expired password by clicking a link on the portal web page. For this you will need to provide answers to security questions that were entered at the time the account was set up

UPDATE March 3, 2021
Current thinking is that it is better to connect to Physical Desktop (more stable).
If NX server crashes and connection to the Physical Desktop is not available, it is possible to restart the NX server:
sudo -l
sudo /usr/NX/bin/nxserver --restart |
