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

Cheat Sheet

Action

Note

Disconnect Session

Press 'F8' > 'Disconnect'

Screen Lock

Activate: Ctrl - Alt - L,
Unlock: to display password prompt, press any key or move the mouse. Sometimes it's necessary to press Esc two times.

USB Stick

~/thindrives

Local files

~/thindrives

Screen Size

Press 'F8' > 'Fullscreen: Disable' to make a fullscreen Window resizable.
This is also useful at the I-MATH Terminals, if the screen size does not fit perfectly to the monitor (deactivate and then activate the fullscreen mode again).

Keyboard Layout

The keyboard will be automatically detected during log in. If you need special characters, the easiest way is to use the 'Compose Key'

  • 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

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!

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 Applications > System Tools > Repair thindrives (USB Stick , ...) .

  • Note: on the Thinstations (they have a an orange startup screen) the USB stick mount is not yet supported

Remote Access: thinlinc@home

By webbrowser

  • https://tl.math.uzh.ch

  • No sound.
  • No local drives
  • For touch based devices (Tablets), you'll find a software keyboard on the top of the window,

By native client

  • Install the native Client (Linux, Windows, Mac): Download

    • At the moment, there is no native Android, Windows Phone or iOS support. Use the webclient instead.

  • Start the native client and connect to: 

    tl.math.uzh.ch
    • Be aware, the second character of the servername is a lowercase 'L'!
    • Username / Password: as your I-MATH Account.

  • It is possible that you have to accept the hostkey: press 'Continue'

hostkey.png

  • Disconnect / toggle Full screen: Pressing 'F8' opens a menu, with options for:

    • Disconnect.

    • changing Full Screen.

  • Best practice: it's not necessary to log out, just disconnect.

Printing at home

  • Choose Thinlocal as Printer
    • It automatically uses your default printer configured on your PC/Laptop at 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 Applications > System Tools > Repair thindrives (USB Stick , ...).

Dropbox

You can also use dropbox or switchdrive to copy data to the thinlinc session.

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 rigth corner:

      • Applications > Configuration > Keyboard > Keyboard Layout: Edit ...

  • Website to convert keystokes to specific languages: http://www.typeit.org/

Audio

General

  • Audio redirection only works with the native client - not with the thinlinc browser version.

  • If there is no sound at all (verify by playing a youtube video), check the 'Audio redirection' via Applications > Sound & Video > Pulse Audio Volume Control

    • ok: Output: Tunnel to 127.0.0.1:5...

    • broken: Output: Dummy output

Y27

  • For using 'headphones', please check if there is a 3.5mm jack at your monitor (varies with the models).
