Recommended System Requirements for Smooth Performance
For an optimal experience, it is best to opt for hardware that exceeds the system requirements so that you do not encounter any turbulence. Here are the recommended specifications for running Ubuntu smoothly on desktop and servers, both.
- CPU Requirements
- Ubuntu Desktop: Quad-core processor (Intel i5/i7, AMD Ryzen 5/7, or better)
- Ubuntu Server: Multi-core processor (x86_64, ARM, or POWER architecture)
- Lightweight Flavors (Xubuntu/Lubuntu): Dual-core processor or higher
- RAM Requirements
- Ubuntu Desktop: 8 GB (16 GB for heavy multitasking, development, or virtualization)
- Ubuntu Server: 2 GB (4 GB or more for high-performance tasks)
- Lightweight Flavors:
- Xubuntu: 4 GB recommended
- Lubuntu: 2 GB recommended
- Storage Requirements
- Ubuntu Desktop: 50 GB free space (100 GB or more for heavy applications)
- Ubuntu Server: 20 GB or more, depending on the workload
- Lightweight Flavors:
- Xubuntu: 20 GB recommended
- Lubuntu: 15 GB recommended
- Display and Graphics Card Needs
- Resolution: 1920×1080 (Full HD) or higher for best experience

Ubuntu on Low-End Hardware
Ubuntu system requirements for low-spec hardware are as follows:
- Best Ubuntu Flavors for Low-End Systems:
- Lubuntu (Uses LXQt, very lightweight) – Ideal for PCs with 1 GB RAM or more
- Xubuntu (Uses Xfce, lightweight) – Works well with 2 GB RAM or more
- Ubuntu MATE (Uses MATE, moderate resource usage) – Good for systems with 2-4 GB RAM
- Performance Optimization Tips:
- Disable animations and visual effects
- Use lightweight applications (e.g., Thunar for file management instead of Nautilus)
- Reduce startup applications and background services
However, for low-end hardware, it is best to select the right versions.
Checking Your System Compatibility
Before you go all in with Ubuntu, it is best to check if your system is actually compatible with it or not.
- On Windows:
- Open Task Manager → Performance to check CPU and RAM
- Open File Explorer → This PC → Properties for system details
- On Linux:
- Run lscpu to check CPU specs
- Run free -h to check available RAM
- Run df -h to check available storage
- Using Ubuntu Live USB:
- You can test Ubuntu without installing it by booting from a USB drive and selecting “Try Ubuntu”
Virtual Machine Requirements for Ubuntu
For virtual machine, you need to follow these Ubuntu system requirements:
- Minimum VM Requirements (Basic Usage):
