ARCHIVED: Troubleshoot Karst Desktop

UITS Research Technologies retired the Karst Desktop service on December 31, 2018.

Its replacement, the Research Desktop (RED) service is functionally equivalent to Karst Desktop, except:

  • To use RED, you need an account on Carbonate; for information about getting a Carbonate account, see Research system accounts (all campuses).
  • RED's dedicated nodes run Red Hat Enterprise Linux 7 (RHEL 7), whereas Karst Desktop nodes ran RHEL 6.

If you have questions about using RED or need help, contact the RED development team.

Screen size issues

If the Karst Desktop window covers your entire display, hiding control menus or positioning them off-screen, use the following keyboard shortcuts to either exit full-screen mode or terminate ThinLinc Client. Whichever method works for you, make sure to change the ThinLinc Client screen size settings before launching another Karst Desktop session; for help, see ARCHIVED: Download, install, and configure ThinLinc Client to use Karst Desktop at IU.

  • Exiting full-screen mode: Click the display background to make sure Karst Desktop is the active window, press F8 to open the pop-up menu (depending on your system, you may need to press Fn-F8 or Win-F8), and then de-select Full screen.
  • Terminating ThinLinc Client: If you cannot exit full-screen mode, you may need to terminate or force quit the ThinLinc client. To do so, click the display background to make sure Karst Desktop is the active window, and then:
    • In Windows, press Alt-F4 or Esc. Alternatively, press Ctrl-Alt-Delete or Ctrl-Shift-Esc, and then select Start Task Manager; then, on the Applications tab, select ThinLinc Client, and then click End Task.
    • In OS X, press Command-Option-Esc to open the "Force Quit" window, select ThinLinc Client, and then click Force Quit. Alternatively, press Command-Tab to switch to the last used application; then, from the Apple menu choose Force Quit..., select ThinLinc Client, and then click Force Quit.

      If you cannot force quit ThinLinc Client, you may need to log out of your OS X user account or reboot your computer. To log out of your user account, press Command-Shift-q. To reboot your computer, press Ctrl-Eject, and then select Restart.

Login issues

Issues with thindrives

  • If an exported local drive or directory in your thindrives folder is not responding, check the ThinLinc Client options to make sure you entered a valid path (see the ARCHIVED: Exporting local drives and folders section in ARCHIVED: Download, install, and configure ThinLinc Client to use Karst Desktop at IU.)
  • If you cannot copy files to an exported local drive or directory in your thindrives folder, check the ThinLinc Client options to make sure the path you entered is correct and has read/write permissions assigned.
  • If you have an open session and log into it from a different computer than the one that originally was used to open the session, the thindrive icon will not be connected to a valid location.
  • If you are sure you have correctly exported your local drive's folder(s) and you do not see anything in your thindrives folder, try logging out (not just disconnecting) and logging back in. If you configured export of your local drive after your session was already running, the thindrives folder will not have been configured, since it only gets configured on login.

Issues with Firefox

  • If you open any of the desktop icons that start Firefox (e.g., Karst Desktop Help or Scholarly Data Archive) or click on the icon in the browser, and then quickly open Firefox using another one of those methods, Firefox may fail to launch, displaying the following error message:

    Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system.

    If this happens, wait some time before trying again, and then Firefox will open without a problem.

  • The following situations can cause Firefox to crash:
    • Attaching files through the Outlook Web App using Insert > Attachments: As a workaround, download the files to your local computer and send them from there.
    • Accessing Box and clicking Upload: As a workaround, use one of the following options:
      • Drag your file icon into the Box folder.
      • Download your file to your local computer and upload it to Box from there.

    To download files from your Karst account to your local computer, use either of the following methods:

Other issues

  • The File Browser may change on its own to a directory one level up. This seems to happen most frequently to users navigating the Data Capacitor II file system. This is a known issue; UITS administrators are working on a solution.
  • If your computer's operating system is set to a language that is not supported, ThinLinc Client may not function properly.
