Ubuntu installation errors on Mini PCs often stem from UEFI/BIOS misconfigurations, driver incompatibilities, or partitioning issues. To resolve these, verify Secure Boot settings, use Ubuntu LTS versions for stability, and ensure proper disk formatting. Advanced troubleshooting includes kernel parameter adjustments and checking hardware-specific compatibility lists. Always test with a live USB before full installation.

How to Resolve UEFI/BIOS Configuration Issues During Installation?
UEFI/BIOS conflicts cause 60% of Ubuntu installation failures on Mini PCs. Disable Secure Boot in BIOS settings, enable Legacy/CSM mode if available, and ensure the boot order prioritizes the installation media. For NVMe drives, switch from RAID to AHCI mode. Manufacturers like Intel NUC often require BIOS updates for Ubuntu compatibility.
Recent Mini PC models with 12th Gen Intel processors need special attention to Thunderbolt settings in BIOS. Disable “VT-d” technology if experiencing installation freezes, and enable “Above 4G Decoding” for systems with multiple GPUs. Some Chinese-made Mini PCs require manual entry of GRUB parameters like “acpi=force” to bypass firmware quirks.
How to Fix Graphics Driver Conflicts on Ubuntu Mini PCs?
AMD/NVIDIA GPUs in Mini PCs may cause blank screens during installation. Add nomodeset to GRUB parameters by pressing E at the boot menu. Post-installation, install proprietary drivers via “Additional Drivers” tool. For Intel Iris Xe graphics, use kernel 5.13+ and enable i915.enable_guc=2 in /etc/default/grub.

Modern Mini PCs with hybrid graphics configurations require additional steps. For systems using both integrated and discrete GPUs, create an xorg.conf file with explicit device ordering. Users of NVIDIA Optimus technology should install prime-select and switch between GPUs using prime-select intel or prime-select nvidia. Monitor power consumption with nvidia-smi as some Mini PCs may throttle performance due to thermal constraints.
| GPU Type | Recommended Driver | Kernel Requirement |
|---|---|---|
| Intel Integrated | i915 | 5.4+ |
| NVIDIA MX450 | nvidia-driver-535 | 5.15+ |
| AMD Radeon RX | amdgpu | 6.2+ |
Why Does Wi-Fi Fail to Detect After Ubuntu Installation?
Many Mini PCs use Broadcom or Realtek chipsets requiring non-free firmware. Connect via Ethernet and run sudo apt install bcmwl-kernel-source or rtl8821ce-dkms. For Intel AX210 WiFi 6E adapters, install Linux firmware 2022+ and disable power saving with iwconfig wlp0s20f3 power off.
“Mini PCs present unique Ubuntu challenges due to customized firmware and thermal constraints. Always check OEM support pages – companies like Zotac and Gigabyte now offer Ubuntu-specific BIOS updates. For mission-critical deployments, I recommend testing against Ubuntu’s certified hardware list and using USB-C docks for additional peripheral compatibility.”
