- | FIXME | + | Once you have verified that your Windows is recent enough, you should also: |
+ | * Install the [[other:win10apps#windows_terminal|Windows terminal]], because it will be one of the ways to open ''Ubuntu'' terminals, once ''Ubuntu'' is installed | ||
+ | * Have at least some basic knowledge of Linux... | ||
+ | * Get some [[other:newppl:starting#useful_documentation_for_beginners|basic Linux documentation]] if required | ||
+ | ==== Computer CPU and memory ==== | ||
- | ==== Disk space ==== | + | Contrary to other virtual machines, WSL is well integrated with the Windows operating system and the hardware drivers and has a **low default CPU and memory footprint**! |
+ | |||
+ | * You should be able to //play// with WSL even with 8 Gb of RAM, but 16 Gb is recommended | ||
+ | * Of course, depending on what you need to do on your computer, a better processor will always help | ||
+ | * WSL+Ubuntu will use more CPU and RAM if you use it for running CPU and/or memory intensive processes! As would be the case with any Windows application... :-) | ||
+ | |||
+ | |||
+ | ==== Disk usage ==== | ||
+ | |||
+ | === Overview === | ||
+ | |||
+ | * ''WSL'' is part of the Windows operating system and will be installed (and updated) on ''C:\'' | ||
+ | * The Linux installation(s) will be installed (and updated) on ''C:\'' | ||
+ | * They can only be relocated to other partitions afterwards | ||
+ | |||
+ | * => We should **start with at least 10 Gb of free space on ''C:\''** (but more space is always better and safer) | ||
+ | * The initial installation will not use much space (2-3 Gb), but we always need space on ''C:\'' for other applications and Windows maintenance (temporary files, updates, ...) | ||
+ | |||
+ | === How does it work? === | ||
+ | |||
+ | WSL+Linux seems to use a combination of actual Windows files/folders and ''ext4'' Linux partitions stored in ''.vhdx'' ([[https://docs.microsoft.com/en-us/openspecs/windows_protocols/ms-vhdx/83f6b700-6216-40f0-aa99-9fcb421206e2|Dynamic Virtual Hard Disk]]) files. The Linux disk (of type ''ext4'') is stored in a single ''some_name.vhdx'' Windows file that will automatically grow until it reaches a predefined maximum size of 256 Gb (if there is enough space on the Windows disk...) | ||
+ | |||
+ | * Check [[https://docs.microsoft.com/en-us/windows/wsl/vhd-size|Expand the size of your WSL 2 Virtual Hard Disk]] if you need more than 256 Gb | ||
+ | * Check the following threads if you want to reduce the size of the ''vhdx'' file: | ||
