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.... |

TLXOS licenses are perpetual, although historically your ability to upgrade TLXOS used to be time-limited to three years from the date of license activation (the "Support Expiry" date; in practice we ... |

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 ... |

It's difficult to answer a generic question about TLXOS "lockdown", because this is a vague term that means different things to different customers. We have conflicting requirements from customers th... |

Yes, TLXOS is Linux. It's is a slightly modified version of Debian stable (currently 10 (Buster) for 4.9.x or 8 (Jessie) for 4.8.x). TLXOS RPi IoT is based on Raspbian instead of Debian because Debi... |

In TLXOS 4.x: RePC and NUC32 (ISFF) are both, NUC64 (ISFF/SFF) is 64-bit, RPi and RPi IoT are 32-bit.
On x86 platforms, TLXOS typically uses a 64-bit kernel. TLXOS SFF/ISFF (a.k.a. NUC32/NUC64) uses ... |

TLXOS RPi IoT supports all Raspberry Pi models with an ARMv6 CPU, such as the version 1 Pi models, the Zero / Zero W, and the original Compute Module. TLXOS RPi IoT does not support HDX or Horizon m... |

Have you turned Secure Boot off? TLXOS does not support Secure Boot.
There are some other known issues - we'd argue they are BIOS bugs - with certain UEFI BIOSes. Known offenders include Dell Optipl... |

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. Consequently, if you want RDP ... |

The answer depends on which application you are using, and whether or not you have enabled ThinLinX's Kiosk Mode option.
Many applications, such as FreeRDP (RDP mode), Citrix Workspace App (HDX or Web... |

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... |

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:

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... |

Yes, except on early models of Raspberry Pi. Pis earlier than the Pi 3 can't network boot at all, the Pi 3B's network boot firmware is so buggy as to be unusable, and while the the Pi 3B+ can network... |

Yes. TLXOS is fundamentally just Debian Linux, so you can use standard Debian tools such as apt-cache and apt-get to locate and install additional software, and perform whatever configuration changes... |

It's likely that you are trying to license hardware that we have blacklisted, particularly if you are using a version of tms_client earlier than 8.3.0.
Prior to TMS / tms_client 8.3.0, our licensing o... |

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.

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... |

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!)... |

We deliberately disabled client-side multimedia and HTML5 rendering in TLXOS for HDX and Horizon modes because it just wasn't worth the hassle. The Linux ports of Citrix Workspace App and VMware Hori... |

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... |

If HDX mode is asking for logon credentials more than once, or credentials saved using the "Auto Login" feature are being ignored and you are still being interactively prompted, then the most likely c... |

Short answer: The releases are functionally near-identical, the main difference is that 4.8.x has older Citrix, VMware and RDP client versions; use 4.8.x only if you need to, and 4.10.x otherwise.

You may change the boot image if you wish - we use the usual Plymouth boot splash system used by most mainstream Linux distributions, and have not gone out of our way to obfuscate this in any way - bu... |

Starting from TMS/tms-client 8.3.0, it is possible to use your own Public Key Infrastructure for TMS and tms_client. This is useful in order to prevent unauthorized TMS instances from reconfiguring y... |

You don't have to buy our hardware.
ThinLinX is currently a software-only company. We don't sell hardware, so you are free to acquire whatever compatible hardware you wish. We can't guarantee that... |

There are a few use cases for which a Pi with 2 GB of RAM might be beneficial:
Use of Video Conference mode - this application uses a lot of RAM

Because clients can't locate a remote TMS server by magic! Unless your devices are on the same TCP/IP subnet as the TMS server - in which case they will locate it by detecting periodic broadcasts - y... |

There could be application/mode-specific reasons for this - you may wish to check other Knowledgebase articles specific to RDP mode and |

Yes, but it is very out-of-date and is not currently maintained as it was diverting staff time away from higher priority work. We hope to provide a new version of this based on CentOS 8 (rather than ... |

Because we are phasing out the Support Expiry concept. We've concluded that so little of our income comes from license renewals that this limitation just causes needless confusion and - because of hi... |

If you want to install TLXOS RPi, consider using Raspberry Pi Imager instead. We have made it easy to image SD cards using this tool.

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... |

Using TMS is the best and easiest way to perform TLXOS upgrades, and TMS is currently free, so there is no reason for you not to use it.
However, we have given some thought to providing an alternative... |

"xdg-open" is a generic means of launching a helper application from a web browser in Linux. Commercial web UIs often use this to either try to detect the existence of, or install, a better alternati... |

Yes, this is possible, because clients connect to TMS, rather than the other way around, which allows the connection to work over NAT translation.
At the TMS server end, you will need to set up a port... |
|

I could provide a detailed HowTo for the best solution I know of, with screenshots and step-by-step instructions, but this would require an enormous amount of effort, and ThinLinX would derive little ... |

Because that version is out of date.
TMS will display Firmware and TMS Client version numbers using blue rather than black text if a later version is known to be available. It's a gentle hint that yo... |

Not the ARM-based ones, no. TLXOS SFF supports some x86-based Pi lookalikes (e.g. we own an Aeon Up Board and a Rock Pi X), although there may be a few support deficits (e.g. analog audio doesn't wor... |

It's possible that your password may have expired.
This is something of a design flaw in the RDP protocol. NLA authentication - which was not the way RDP authentication was originally conceived (it's... |

Because VNC cannot display accelerated regions of the display that bypass the O/S' usual pixel rendering and interact directly with hardware instead. This is true on every platform, including Windows.... |

Apparently you have been miseducated to expect that you can run anything you want with superuser privilege just by prepending "sudo " to it. This was never the original intent of the sudo utility (se... |

Complicated answer.
The short answer is that (a) you should not attempt to use the ISO installer unless you really need to, e.g. the PC you're booting doesn't support boot from USB, or you're installi... |
|

Because, unlike x86-based PCs, the Raspberry Pi does not support monitor hotplug (i.e. changes to the video configuration after boot-up). This is not a failing of TLXOS, it's limitation of the Raspbe... |
