WIthout any error message i cannot help further. Is there any error log or can you see any error message? Try to start mysqld from /opt/lampp/bin manually, maybe you get more info. Maybe you failed to grant correct ownership and rights. With the help of "sudo" there is no need to modify ownership of the lampp folder. Modify ownership with "sudo chown" and rights with "sudo chmod". Its very important to match the rights of the original files.
What i dont know - which Xampp version did you run on Windows? This binary transfer from Windows to Linux only works for same (or nearly same) releases of MySQL (MariaDB). If the Windows release was much older, the binary transfer wont have success. If you used a very old Xampp version, try to install same old linux version (you will find ALL Xampp releases on Sourceforge).
P.S.: This is the wrong forum, this forum is german language only (see above). There is also an english Xampp for Linux forum.
