Yesterday I installed Linux lite, but I have a concern that it is not suitable for my computer.
If it installed ok and is working well then nothing to be concerned about. If it isn't working well then let us know what is happening.
The searchable hardware database might be useful in your research. It has nearly 88,000 records of what hardware is being used to run Linux Lite.
https://www.linuxliteos.com/hardware.phpIn my limited experience, hardware from say 2015 onwards that was designed to run Windows 10 or 11 will be good with Linux Lite 6.x.
Hardware between 2009 and say 2015 designed to run Windows 7 or 8 may be better on Linux Lite 5.x
Earlier hardware that may have been designed to run Vista or XP is probably not suitable.
All hardware needs to be 64-bit capable to run current versions of Linux Lite (5.x or 6.x).
UEFI support was introduced in 5.0.
