Hi
I accidentally ran the command:

Are there Anyone knows how to undo that?
Thanks for your attention guys.

EDIT: See sisco's post. Please use modprobe in this case.

Well:



sudo insmod lp


To load the module into the kernel.

[sisco311]

sudo modprobe lp
or reboot the computer.

Thanks a lot sisco. I tried that. But it showed me this:

insmod: can't read 'lp': No such file or directory

So where "lp" must be? I think I must first "cd" to the directory of my kernel modules and then install one of them. If so, Where lp and other kernel modules are?
Thanks for you attention again:)

[sisco311]

just use the modprobe command instead of insmod.

insmod filename


Is used to add a module independently (for example one that doesnt load on boot), and you muse edit /etc/modules to load a newly added module on boot . Modprobe is the best option for this case, as modprobe will reload the removed lp module. IF you look at /etc/modules, it contains lp.

Thanks guys.
I used "modprobe lp" as you said, But it returns nothing to me. Is it ok?
I seen "/etc/modules" file. It contains "lp", So it seems that my ubuntu still loads "lp" at boot time.
So I think the main problem is SOLVED.:D
---------------------
No its not solved yet!

Hi guys.
I tried all you said. my /etc/modules contains "lp" in it. but I cant see any file like "lp" or "parport0" in my /dev directory.
The parallel port completely removed from my ubuntu and I don't now how to bring it back.
Please help me.
Thanks for your attention.

No matter what I do, Linux will not recognize my Printer port. I can not see any partport0 or lp file in /dev directory.
Any help?

Is your parallel port enabled in the BIOS?

Is your parallel port enabled in the BIOS?

Yes. I must add that I need Parallel port for programming micro-controller chips. Right now I use to reboot to windows, start codevision software, and program my chip, and the parallel port works well there:( Which is annoying!
Any Idea?

BUMP!
-----------------------
Ubuntu 10.04 32bit parallel port isn't detected! :(

Does lspci -vv see the parallel port?
