In Linux, i don't think it will be as easy as turning NumLock off! I don't know what was wrong with X system configuration, it was working fine, but was too slow, even slower in GNOME. I think that error used to take place only when I used to start GNOME, I am quite sure it wasn't due to KDE.
I think there might be some program running in the background at startup, which handles all this logging, and disabling it should stop the logging, but I'm not sure, I'm new to Linux.
Anyway, I had to remove RH 8, it was having way too many problems than I could handle!
It was giving some damn error on startup and asking me to run fsck. I had no idea what arguments that function took, and fsck -h didn't help. Plus, it was too slow, so I couldn't take it anymore! Now, I'm experimenting with other distros, might get back to it later.
But the next time I try any distros, I would like to disable logging first! It only slows the PC down!
