Support for NVIDIA GPU on ThinOS 10.x

ThinOS 10.x adds support for NVIDIA GPUs, delivering enhanced graphics performance and extending compatibility for workloads that rely on hardware‑accelerated rendering.

Enhancements:

• Added NVIDIA GPU support on supported platforms, including Dell Precision 3280 and Precision 3260, enabling multi‑monitor configurations.
• Supports connecting up to four 4K displays, which is the recommended configuration for optimal user experience.
• NVIDIA support is powered by the Nouveau open‑source driver, providing basic hardware‑accelerated rendering for desktop and window management.

Usage considerations:

• Multi‑monitor support enables desktop and window rendering; however, video playback across multiple monitors is not supported.
• This capability is designed for productivity and general desktop workloads, not high‑performance graphics, gaming, or multimedia‑intensive use cases.
• Due to driver limitations, refresh rates and frame rates may be limited to approximately 30 FPS, depending on the configuration.

Capture device screenshot using WMS

ThinOS 10.x adds support for requesting a screenshot remotely from the WMS Device Details page, enabling quick visual troubleshooting and device state verification.

Support for Wi‑Fi 7

ThinOS 10.x adds qualified support for Wi‑Fi 7, offering faster wireless speeds, improved reliability, and lower latency for demanding network environments.

For more information, see Dell ThinOS 10.x Administrator Guide at Support | Dell.

Support for Dynamic Host file

ThinOS 10.x adds dynamic host file updates, allowing the system to modify host entries automatically and simplifying VDI session configuration similar to Citrix Configuration Editor.

For more information, see Dell ThinOS 10.x Administrator Guide at Support | Dell.

App Builder enhancements

ThinOS 10.x adds the ability to auto‑launch CI applications that is based on configurations set in WMS or APT.

Auto‑launch CI applications:

• Applications that are configured in WMS or APT are automatically launched at startup or reboot.
• ThinOS uses the corresponding .desktop file to initiate the application during system initialization.

ThinOS 10.x introduces automated icon visibility management for CI applications.

Auto Icon visibility:

• When enabled in APT or WMS, CI application icons automatically appear in the VDI menu.
• When disabled, icons are hidden, ensuring UI behavior aligns with administrative policy.

For more information, see Dell ThinOS 10.x App Builder User's Guide at Support | Dell.

BIOS password change using multiple passwords

ThinOS 10.x introduces enhanced Current Password support in WMS, enabling administrators to specify up to three possible existing BIOS passwords during a policy deployment.

This capability is designed for environments where devices within a WMS group may have inconsistent or unknown BIOS passwords. WMS automatically evaluates the provided password options, determines which one is valid for each device, and then applies the new unified BIOS password.

WWAN support

ThinOS 10.x adds support for Wireless WAN modules using Qualcomm Snapdragon chipsets, enabling administrators to configure WWAN so devices can connect to mobile networks with an active physical SIM card and establish reliable cellular connectivity.

For more information, see Dell ThinOS 10.x Administrator Guide at Support | Dell.

Enable or disable the Taskbar volume icon

ThinOS 10.x allows administrators to enable or disable local client volume icon centrally through APT or WMS policy configurations.

This change affects only the local device UI, audio functionality within VDI sessions and the browser remains unaffected.

Improved P2P remote shadow connection times

ThinOS 10.x optimizes peer‑to‑peer remote shadowing, significantly reducing connection times and improving remote support responsiveness.

• Reduced P2P connection setup time from 40–60 seconds to 10–20 seconds, improving overall session startup speed.
• Improved responsiveness during remote session initiation for a smoother and faster user experience.
• Enhanced scalability and reliability of connection management to support higher session volumes and more stable connectivity.

Loading indicator for browser launch

ThinOS 10.x introduces a loading spinner when launching the browser or browser shortcuts, preventing users from unintentionally opening multiple duplicate tabs during initialization.

• Adds a visual loading spinner to indicate progress during browser launch.
• Provides a user‑friendly status message confirming that the browser launch has started.
• Automatically dismisses the spinner once the browser window is fully ready.
• Enhances the overall user experience by offering clear launch feedback and reducing accidental multi‑tab openings.

Support for recent Citrix sessions in WMS

ThinOS 10.x adds support for recent Citrix sessions visibility and desktops session names within the Recent Sessions section of WMS device details, improving session tracking and troubleshooting.

• Improves visibility and reduces ambiguity in environments where store names and desktop session names are similar.
• Simplifies troubleshooting by enabling administrators to trace the Citrix login path directly from WMS.

For more information, see the Dell ThinOS 10.x Administrator Guide at Support | Dell.

Custom background information fields for group policies

ThinOS 10.x adds support for custom fields in Group Policies, enabling granular control of background information to meet institutional or organizational requirements.

• Displays the current date and time directly on the Desktop Background Information panel, improving at‑a‑glance visibility.
• Eliminates the need to open the Start menu or check the taskbar to view system time.
• Provides real‑time updates synchronized with the system clock.
• Switching between 12‑hour and 24‑hour formats requires a device reboot.

For more information, see Dell ThinOS 10.x Administrator Guide at Support | Dell.

Support for Software TPM

ThinOS 10.x adds support to Software TPM (sTPM) on ThinOS 10 to ensure that Full Disk Encryption (FDE) and security features continue to operate reliably even when Hardware TPM (hTPM) is unavailable or cannot be accessed. As part of this enhancement:

• Software TPM is automatically used as a fallback when Hardware TPM is missing or fails to initialize.
• Encryption conversions continue to work even if the TPM is in a locked‑out state.
• FDE protections and associated security functions remain fully enforced without any reduction in security posture.

Other enhancements

• Added support for the Tangent Medix 24 v3 as part of the Hardware Compatibility List (HCL) initiative, ensuring reliable ThinOS performance on certified medical‑grade hardware.
• Added support for the Dell Ultrasharp 52 Thunderbolt monitor on compatible ThinOS 10.x devices, enabling seamless display integration and Thunderbolt connectivity.
