Thinlinc

• For login,  check your MFA

Cheat Sheet

• Accessing the same session locally (at the institute) and remotely (for example at home) - no hassle anymore with locked Firefox profiles.
• IT Support: on your request, it is possible to 'shadow' your session to the IT group - in case of any trouble - just call the IT by phone.

Connect Session

• Use any of the Terminals at the institute or use the 'native client' (see below) application on your own computer (Internet access is needed).
• Just login.
  • An already existing session (in the background or on another terminal) will be moved and reconnect you.
• Server: tl.math.uzh.ch

• By default, the Session is fullscreen. To change this, open the 'popup menu' by pressing F8 and change Full screen.

Disconnect Session

• Press F8 to open 'popup menu' and choose disconnect.
  • If you need the 'F8 key' in an application, assign another key for the popup menu. To do so: F8 > Options > Options > Popup Menu Key. The new setting is only active during the recent connected session.

Get a new and fresh session

Sometimes it happens that your session is locked for some reason (crashed apps, quota problem, ...). A session disconnect / reconnect does not improve the situation.

Please check the option End existing session in the tlclient login window and log in again. Your old session will be killed and a new session will be created. All open applications will be terminated. Open files might be lost. Use is with caution!

• This option is not available via Webaccess.

USB sticks: Terminals in building Y27

• If you plug in a USB Stick at the terminal, there is no window, which opens automatically.
• Plugged in USB sticks or ext. hard drives will appear in your home directory under the folder thindrives.
• Open a Filemanager (Menu: Places) and navigate to your 'home directory > thindrives'.
• Mount and unmount happens automatically - wait a few seconds.
• If you copy data, wait until the light on the USB stick stops flashing or the progress bar disappear, plus some additional seconds. After that, it's secure to remove the stick.
• If the stick does not appear under directory '~/thindrives', please trigger a remount via menu Repair thindrives (USB Stick , ...).

Video

• https://webcammictest.com/
• (Check) If your camera is not recognized by the application, open a terminal and enter tlwebcam-ctl list-cameras, to make sure the camera is connected in the first place. There needs to be at least one camera listed.

• (Fix 1) If broken: Disconnect (F8 > Disconnect) Thinlinc Session and log in again. Reload the browser page.
• (Fix 2) Power the terminal off and on . Connect again to the Thinlinc session. Reload the browser page.
• (Fix 3) If the cameras' light isn't on and the camera doesn't display anything in your VideoMeeting/Recording, enter tlwebcam-reload in the Terminal, to reload the service completely.

Audio

• Audio redirection only works with the native client - not with the thinlinc browser version.
  • Tablet: There is no sound redirecting, because there is no native client.

Fix Problem

• https://webcammictest.com/mic/
• Check: If there is no sound at all (verify by playing a youtube video), check the 'Audio redirection' via Pulse Audio Volume Control
  • ok: Output: Tunnel to 127.0.0.1:5...
  • broken: Output: Dummy output

• Fix 1: If broken: Disconnect (F8 > Disconnect) Thinlinc Session and log in again. Wait 5 seonds, 'Dummy...' should be replaced by 'Tunnel...'. This fixes the majority of audio issues!
• Fix 2: Audio / Mic is not working - do the following steps, exact in the given order:
  • F8 > Session disconnect and than login again.
  • Unplug the USB Headset, wait 3 seconds and plug in again.
  • If the System is using the wrong Audio Device or Microphone, unplug and plug again the desired device.
• Fix 3: If still 'Dummy...' appears (see 'Check'), `Logout' completely (Menu > Logout) and log in again. If this is often necessary (more than once a month), contact Support.
