Use sudo and at to schedule the usermod command, which changes the user's home dir.
sudo at "now +5 minutes" # Run the following commands in 5 minutes
In the at interface
usermod -m -d /new/home/path # Change user home dir (-d) and move (-m) the content into the new folder
Ctrl+D to exit the at interface. Logout, wait 10 minutes, and login.
How to solve the "AMD system not detected" error when installing AMD chipset driver in Windows 11 24H2.
Install VBS support: Settings > System > Optional features > Add "VBSCRIPT". You should be able to install the driver afterward.
Use heredoc to pass the string as-is between two delimiters (e.g. EOF)
cat << "EOF" >> ~/.xprofile
# ~/.xprofile
export GTK_IM_MODULE=ibus
export QT_IM_MODULE=ibus
export XMODIFIERS=@im=ibus
ibus-daemon -drx
EOF
Will append the following lines in ~/.xprofile:
export GTK_IM_MODULE=ibus
export QT_IM_MODULE=ibus
export XMODIFIERS=@im=ibus
ibus-daemon -drx
ppa-purge to remove currently activated PPAs. The unremovable git-lfs gave me headache for several hours.Ubuntu 24.04 (with kernel 6.8) may give an error while mounting NTFS partitions.
Solution: disable the open source ntfs3 driver and force Ubuntu to use the old ntfs-3g driver. Reboot to apply.
echo 'blacklist ntfs3' | sudo tee /etc/modprobe.d/disable-ntfs3.conf

Set up Windows subsystem for Linux 2 (WSL2) for Linux development experience in Windows 10 and 11.
Open powershell with administrator privilege, run the following command in the host.
wsl --install --no-distribution
or install the components manually
dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart
dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart
After reboot, install the Linux distribution
wsl --update
wsl --set-default-version 2
wsl --install -d Ubuntu # Or another Linux distribution
If you want to move the WSL virtual disk file to another disk (in this example, D:\), run the following commands in Windows12:
wsl --export Ubuntu .\Ubuntu\ext4.tar
wsl --unregister Ubuntu
wsl --import Ubuntu D:\Ubuntu\ .\Ubuntu\ext4.tar
Edit /etc/wsl.conf in the WSL. You may need to set the default user if you have moved the virtual disk file of the WSL distribution.
[user]
default=username
Edit .wslconfig 3 in your Windows home directory (%USERPROFILE%).
For example,
[wsl2]
memory=20GB # How much memory to assign to the WSL2 VM.
swap=8GB # How much swap space to add to the WSL2 VM. 0 for no swap file.
swapfile=C:\\temp\\wsl-swap.vhdx # Sets swap file path location, default is %USERPROFILE%\AppData\Local\Temp\swap.vhdx. Useful if your C drive has limited disk space.
Edit .wslconfig 3 in your Windows home directory (%USERPROFILE%). 4
[experimental]
autoMemoryReclaim=gradual # Reclaim RAM usage
sparseVhd=true # Reclaim virtual disk (vhd) usage
To (manually) update the WSL kernel, run the following commands with administrator privileges:
wsl --shutdown
wsl --update
Note
Optimize-VHD is not available in Windows Home edition.
To reclaim disk space from virtual hard disks (VHDs), run the following commands with administrator privileges 5:
wsl --shutdown
Optimize-VHD -Path %path-to.vhdx% -Mode Full
Alternatively, export the VHD as a tar file and reimport it again.
Cross-OS file access (e.g., accessing /mnt/c in WSL) is at least one order of magnitude (10x) slower than accessing natively (/home/user/).7
