Samsung NB30 JT01IT Touch Screen Problem

[TheOldMan]

First of all, thanx very much guys for this wonderful site. I just solved the FN Keys problems thanx to your guide.

Now... getting to the problem.
I bought the Samsung Nb30 JT01IT, that black semi-rugged net-book, equipped with a 10" touch screen.
Of course under Ubuntu 10.10, it doesn't work.
To be honest, it doesn't work with other versions of Ubuntu either; I tried the Unity NetBook Interface as well.
Is there a way to make that touch display working under Ubuntu?

Thanx in advance...

Hi,

I've got the UK version of the NB30 and I've just managed to get the touch screen to work after reading this blog post (although I did need to so some steps differently and didn't need other steps): http://samiux.blogspot.com/2010/11/howt ... hnote.html

Here is what I did:
Identified the touchscreen device by typing lsusb in a terminal and found:

Code: Select all

Bus 002 Device 002: ID 0eef:480e D-WAV Scientific Co., Ltd 

The hex numbers are important to note and are used in the next step, they also differ from the hex numbers in the samiux blog post.

Then I amended /etc/default/grub (sudo nano /etc/default/grub) and made sure the GRUB_CMDLINE_LINUX_DEFAULT line said this:

Code: Select all

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash usbhid.quirks=0xeef:0x480e:0x40"

Save and run this command in the terminal:

Code: Select all

sudo update-grub

Now we need to stop a conflicting driver from loading, in the terminal enter:

Code: Select all

sudo nano /etc/modprobe.d/blacklist.conf

At the end of this file add this line:

Code: Select all

blacklist touchscreen

Save the file and reboot the machine. The touch screen should now (fingers crossed) work. I found I did not need the other steps in the original blog post (maybe these were only for 10.04).

Hope this helps.

eh eh eh
It works indeed !!!
Thanx liamgh... outstanding guide !!!
I very much appreciate your help. Thanx for sharing a little bit of your time.
see you around

Ps
For those who don't know how the Nano Editor works:
- at the end of the procedure suggested by liamgh hit CTRL + X (to exit the editor)
- then hit the "y" key on the keyboard ("y" stands for "Yes I wish to save the changes")
- hit the RETURN key on the keyboard
- done

[a bit off topic... sorry]

>:(

Unfortunately after a System Update on my Samsung NB-30 (touchscreen) everything went back to the original mess:

- backlight management is not working anymore
- wireless is not working anymore
- FN keys not working anymore
- touchscreen working though

The original fixing methods, such as installing Samsung-tools from the Voria PPA repository seem not to be working anymore.

Very frustrating indeed.

Anyone?

sorry for the delayed response. i have a nb30 (np-nb30-ja01us) not the touchscreen but i lost backlight controls using ubuntu 10.10 after the system update. Reinstalling the samsung-tolls and backlight didnt fix it. I had to go back to 10.04. There another open forum on this problem.

you should post there if your still having these problems, or post there how you fixed it for everyone.

i know its not a lot at least you know your not alone haha

Thanx for the hint.

Yet no fix for that problem... I went back to v. 10.04 me too...
