 * The 'thinlic' environment will replace the 'Sun Ray' terminals during 2013.
 * Advantages of Thinlinc against 'Sun Ray':
  * Supports latest Linux OS natively.
   * This is the main reason for the migration.
  * Much better grafic speed:
   * Smoother scrolling on websites.
   * Playing Videos.
  * Much better USB Stick support.
  * Accessing the same session locally (at the institute) and remotely (for example at home).
  * IT Support will be possible by 'shadow'-ing the session with the IT group.
 * Disadvantage
  * Power on takes longer.
  * Sound problems after reconnecting the session. Start the application again (for webbrowsers: reload the webpage).
  * At the moment 'Smart Card' support is not enabled.

= Terminals at the institute =
 * Login with your regular I-MATH account.

= Terminals outside the institute: thinlinc@home =
 * Install the native Client (Linux, Windows, Mac) - no Android or iOS Support.
  * Download: http://www.cendio.com/downloads/clients/
 * Start the native client `tlcient` (it's a standalone application, it's not a browser version)

  * 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'''
{{attachment:tlclient.png}}
 * 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!

{{attachment:tl.end.existing.session.png}}

 * 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 , ...)'''.

= Remote Access: thinlinc@home =

== Copy files from/to the Thinlinc Session ==

 * This is is very similar as with the USB sticks above.
 * Add a mapping of local directories to the '''~/thindrives''' directory inside the thinlinc session.
 * Do the mapping '''before''' you connect to the session:
  1. Open the 'Thinlinc Client' and choose '''Options > Local Devices > Drives: Details'''
  2. Add a new directory and set '''permissions'''.
  3. If there are '''troubles''' with a mapped directory: inside the thinlinc session, choose the menu '''Repair thindrives (USB Stick , ...)'''.

You can also use dropbox or switchdrive to copy data to the thinlinc session.
 * [[https://wiki.math.uzh.ch/public/dropbox|Dropbox]]

= Keyboard Layout =

 * A quick solution, to type characters not directly accessible on the keyboard, is by using the 'compose key' - please check [[ComposeKey]].
 * '''Select keyboard layout''':

   * The Keyboard layout is stored on the terminal.
   * If you move to a different terminal, you have to select the keyboard again.
   * Before you connect to a thinlinc session (or if you are already logged into thinlinc: press F8 and uncheck 'Full screen'), select on the lower left corner:

     `Keyboard > Keyboard Layout: Edit ...`

= WebCam: MS-Teams / Zoom / Skype / SeminarLive =

 * Webcams are only '''supported''' on the terminals, installed at the '''institute'''!
 * Audio/Video '''Test''': https://janus.conf.meetecho.com/echotest.html (press 'Start' on the top)
 * Webcam Support:

   * Terminal in Y27: '''plug in the webcam'''.
   * Personal laptop: '''NO''' webcam support. Please start your !VideoCall outside of the Thinlinc session.

 * You can borrow a webcam and/or a headset from [[http://math.uzh.ch/support|Support]].
 * The Camera will not be available if you are already using it in another application (only one Application can access it at a time)
 * When the camera is on, there is a green light on the left side of the lense.

{{attachment:cam.png}}

 * 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.

{{attachment:listcams.png}}

 * 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.

 * 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'''

 * If broken: Disconnet (```F8 > Disconnect```) Thinlinc Session and log in again. Wait 5 seonds, 'Dummy...' should be replaced by 'Tunnel...'. This fixes the majority of audio issues!
 * If still 'Dummy...' appears, `Logut' completely (System > Logout) and log in again. If this often required, contact [[http://math.uzh.ch/support|Support]].


 * Audio / Mic is not working - do the following steps, exact in the given order:

   * `F8 > Sesssion 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.

 * If there is no printer applet in the lower right corner:

   * Menu > System Settings > Applets > Manage > Printers > Settings > Show printer icon: When printers exist

{{attachment:printer-applet.png}}

= Multi-Head Support =

 * Fully supported via native client.
 * Mac OS X: "macOS (formerly OS X) versions newer than 10.9 installs with a default setting that breaks the multi monitor functionality of the ThinLinc client. A workaround to this problem is to disable setting ''Displays have separate Spaces'' in settings for Mission Control found in System Preferences."
