Can I install/upgrade TLXOS via PXE boot? Article not rated yet
Yes, except - regrettably - on the Raspberry Pi; this is because the Raspberry Pi firmware will never attempt network boot if an SD card is present.  You can, however, boot the Raspberry Pi 3 B+ in "d...
Known issue with TMS <= 8.0.0 on Ubuntu >= 16.04 Article rated 5.0/5.0
Ubuntu disabled SSLv3 at the OpenSSL library level starting from the 16.04 (Xenial) release.  Unfortunately TMS (<= 8.0.0) still uses SSLv3 for (non-HTTPS) data exchanges with tms_client. ...
Root / SSH access to TLXOS devices Article not rated yet
For security reasons, no local user account in TLXOS has a password, including the root account, so it is not possible to access to an interactive root shell by any means that involves password entry....
How does ThinLinX licensing work? Article not rated yet
Our licenses aren't encrypted keys that you enter, they're entitlements that exist on our Internet license server (tls.thinlinx.com), so the server that TMS runs on needs to have access to https://tls...
Changing system language / correcting RDP keyboard layout Article not rated yet
We do not yet have support in the ThinLinX GUIs to do this, but you can do it manually by SSHing to the device as root (by using TMS to upload an SSH public key and then SSHing using the corresponding...
How client devices locate a TMS server Article not rated yet
The TMS agent's (tms_client's) default TMS server discovery behaviour (the "auto" method) tries the "dhcp" method first, then the "static" method (values default to hostname "tms" and port 8085), and ...
Dual displays on a Raspberry Pi Article not rated yet
Unfortinately there is no good solution for this: USB video adapters using DisplayLink chipsets can be made to work, although this is difficult because you have to use XINERAMA screen aggregation rath...
High monitor resolutions on Raspberry Pi Article not rated yet
The maximum resolution we offically support on the Raspberry Pi is 1920x1080, because this is the highest resolution supported by the Pi's H.264 hardware decoder, and without this you will have signif...
Serial port redirection in RDP mode Article not rated yet
TLXOS has kernel drivers for all common USB serial adapters, so your adapter ought to work locally (if you are in any doubt, start a local terminal window using <ctrl><alt>t and use "ls /d...
How to configure HDX mode when using Netscaler gateway Article rated 1.0/5.0
On a newly installed device that has never before connected via HDX, you must enter the Netscaler hostname rather than the Storefront server hostname in TMS/Tlxconfig's Server[:Port] field. When you e...
How to auto-launch a Citrix/Horizon app/desktop only (no app browser) Article not rated yet
It is possible to configure both HDX and Horizon modes to launch a specific published application or desktop without ever letting the user access the main Workspace App Horizon Client / UI.  In both c...
USB redirection in RDP mode Article not rated yet
Unlike Citrix and Horizon clients, the RDP client doesn't have a useful default position on USB device redirection and will not attempt to redirect anything by default.  FreeRDP also normally has hard...
Why doesn't multimedia/HTML5 redirection work? Article not rated yet
We deliberately disabled client-side multimedia and HTML5 rendering in TLXOS (for both HDX and Horizon modes) because it just wan't worth the hassle.  The Linux ports of Citrix Workspace App and VMwar...
USB redirection in HDX mode Article not rated yet
Citrix Workspace App has a default policy that is pretty good at anticipating typical USB redirection requirements, and you will rarely need to alter this.  At present ThinLinX UIs (TMS and Tlxconfig)...
Webcam / USB headset redirection problems on Raspberry Pi Article not rated yet
Both Citrix Workspace App and VMware Horizon Client have ARM ports that are functionally very limited in comparison with their x86/x86_64 Linux ports.  ThinLinx does not have access to the source code...
Missing drop-down toolbar in fullscreen desktop on Raspberry Pi Article not rated yet
Both Citrix Workspace App and VMware Horizon Client have minimally functional support for H.264 hardware acceleration that prevents use of their drop-down toolbars. The nature of the H.264 hardware ac...
CA certificate is not recognised Article not rated yet
If you encounter problems uploading a CA certificate to your TLXOS device, it is probably because it is in the wrong format.  There is a binary format (DER) and a text format (PEM/Base64) and TLXOS re...
How can I lock down configuration so that users can't mess with it? Article not rated yet
You were probably hoping for a solution resembling Active Directory Group Policy, but we don't have the resources to do anything that sophisticated yet (read as: you aren't paying us enough for that!)...
Does TLXOS include a VNC server? Article not rated yet
Yes, TLXOS has a VNC-based session shadowing feature, but it doesn't work the way that you probably think it does.  TLXOS uses stunnel-encapsulated reverse VNC, for three reasons: Forward VNC connecti...
Setting up a TLXOS session shadower on Windows Article not rated yet
How to Shadow TLXOS Devices on a Windows Server/Desktop First Install the latest stunnel for Windows (5.42 at the time of writing) from
Spontaneous Citrix HDX disconnections on the Raspberry Pi Article not rated yet
This is most likely the result of Workspace App crashing, which in turn is likely to be related to use of H.264 hardware acceleration. Up until Reciever 13.7.0, "our" ctxh264.so add-on (which is actua...
USB stick installer won't boot on Intel NUC / Compute Stick Article not rated yet
There are several known issues with the UEFI BIOS on Intel Compute Sticks and certain NUC models (mainly the more recent ones).: In order to boot TLXOS (or pretty much anything other than Windows), yo...
What is TLXOS? Is it Linux? What parts of it are proprietary? Article not rated yet
Yes, TLXOS is Linux.  It's is a slightly modified version of Debian stable (currently 8.x (Jessie), we will upgrade to 9.x, (Stretch) very soon).  TLXOS RPi IoT is based on Raspbian 8.x instead of Deb...
Is TLXOS ISFF/RePC 32-bit or 64-bit? Article not rated yet
Both. On x86 platforms, TLXOS uses a 32-bit userspace but (typically) a 64-bit kernel.  ISFF (a.k.a. NUC32/NUC64) uses a 64-bit kernel only, whereas RePC has both 32- and 64-bit kernels and automatica...
Running multiple fullscreen desktops/applications Article not rated yet
At present, TLXOS is designed to run a single fullscreen application (or desktop) only.  While it is in most cases technically possible to escape from fullscreen mode and launch another session (e.g. ...
Installing TLXOS without overwriting pre-existing storage Article not rated yet
It is not obvious at first glance that it is possible to perform a "careful install" of TLXOS ISFF and RePC by using the installer's "Upgrade/Recover TLXOS" menu option rather than the "Wipe Everythin...
Black screen / immediate disconnection in Horizon mode on RePC Article not rated yet
This happens when H.264 hardware acceleration, using either VA-API or VDPAU, is only partly functional.  While this works reliably on the more restrictive set of GPU hardware supported by TLXOS ISFF, ...
TLXOS keyboard shortcuts (when not in a fullscreen app) Article not rated yet
xbindkeys mappings are as follows: <Ctrl><Alt>c starts the local (C)onfiguration tool (Tlxconfig) <Ctrl><Alt>i (I)dentifies monitors (for mapping displays to output number in T...
High-level (CUPS) printer redirection in HDX mode Article not rated yet
Unfortunately, while redirection of printers from a Windows client is simple and "just works", high-level redirection of printers from a Linux client is arcane and difficult.  If the printer is connec...
What hardware does TLXOS support? Is there a hardware compatibility list? Article not rated yet
No, we do not maintain any kind of HCL - this is not practical for a software distribution that aspires to run on a wide range of desktop hardware. TLXOS RPi IoT supports all Raspberry Pi models with ...
Can I customize / install additional software on TLXOS? Article not rated yet
Yes.  TLXOS is fundamentally just Debian Linux, so you can use standard Debian tools such as apt-get to locate and install additional software, and perform whatever configuration changes you wish. Ple...
Can I customize the installation image prior to install? Article not rated yet
Not really.  Since TLXOS is intended to be a product rather than a custom solution, our main strategy is to perform post-install configuration using TMS rather than pre-install customization. ISFF and...
