I went to visit Free Geek linux help session today for helps in fedora. unfortunately, i did not solve the problem I have with ksynaptics. but i did learn some cool stuff:
mknod -> used for making a device file in /dev. the expert said it's something related to "udev". i should look into it
dpkg-reconfigure xserver-xorg -> used for debian xorg.conf reconfiguration. it doesn't work in fedora, however. it is very useful when your xorg or any other conf file is messed up
locate - a program that updates its file database in midnight and fast search indexing of files
also, in bash, you can double tab in command prompt to list out all files in the directory that contain matching strings you have typed. this is tested and working in bash
------------------
btw, i did some research in Mac file system. apparently Mac file system is much cooler than linux: the reason why mac has such good file searching utility is because mac uses a special autofs device under /dev that can track all the current changes to directories, and file them to the searching index system. this is much better than the locate program unix has because the update is instant.
also, the time machine in Mac has a very advanced technology which allows hard links to directories, which is forbidden in unix because such multiple directory hard linking can cause bad loops. but mac solved that problem, and used it extensively in time machine so that there is only one copy of an tire folder of files if none of the files in the folder has been modified before previous backup. the only problem with it is that even if you just modified one byte in a big file, the file will be saved as separate files from before, this causes problem if you use many virtual machines, or MS Entourage, which saves all emails as a single database file that is often changed and big.
