Dell Latitude 7455 (Snapdragon X Elite) Linux Support: Current Status, Performance & Key Issues

 

Dell Latitude 7455 with Qualcomm Snapdragon X Elite gets Linux patches—USB, WiFi & display now work, but audio & NVMe issues remain. See benchmarks vs. Intel/AMD & whether it’s ready for daily Linux use.

Linux Support for Dell Latitude 7455: Progress & Challenges

The Dell Latitude 7455 (X1E-80-100)—one of the first business laptops powered by Qualcomm’s Snapdragon X Elite SoC—is seeing active development for Linux compatibility. Recent patches submitted to the Linux kernel mailing list enable core functionality, but critical gaps remain before it’s viable for production use.

What Works in Linux So Far?

• USB, WiFi, and Bluetooth – Basic connectivity is functional.

• Display handling – Supports external monitors and built-in screen.

• Keyboard & touchpad – Input devices work as expected.

• Power management – Suspend/resume partially works.

Key Limitations & Hardware Issues

Despite progress, the Snapdragon X Elite on Linux still faces hurdles:

❌ No audio support – Drivers for the integrated DAC/codec are incomplete.

❌ NVMe instability – Storage drops out after suspend/resume.

❌ High CPU usage with WiFi – NetworkManager causes ~1W power drain.

❌ SD card reader errors – I/O failures make it unreliable.

❌ Missing webcam & Iris GPU acceleration – Critical for video calls & graphics.

Performance Benchmarks: Snapdragon X Elite vs. Intel & AMD

Earlier testing on Ubuntu Linux reveals mixed results:

• Single-threaded workloads – Competitive with Intel Core i7-1360P.

• Multi-core efficiency – Falls behind AMD Ryzen 7 7840U.

• Battery life – Windows 11 still outperforms Linux due to driver optimizations.

Is This Laptop Ready for Linux Users?

Not yet—while developers are making strides, the Dell Latitude 7455 lacks polish for daily Linux use. Enterprises and developers may test it, but mainstream adoption requires fixes for audio, storage, and power management.
