Touch Screen Recommendations

I gave up on my ELO and bought an ASUS VT207N that works for people here.
Just got it and of course it doesn't work for me
I found out it works with RTAI, but I have to use RT kernal, and under RT it dosn't work.
It seems that I shall not have a touch screen

I have searched a bit on Google but I can not find anything.
Has anyone else get this screen to work under RT?

I have it working under Preempt RT.

What OS are you on? Did you issue modprobe as stated above?

Oh, that sounds promising!
I issued modprobe, and it works with RTAI kernal, but not RT.
I use latest iso from linuxcnc download with all updates. uname - v = SMP PREEMPT RT Debian 3.2.84-1

Are you using an other OS?

I started to look at Linux Mint and found out that you are using that.
I will give Mint 17.3 a try.
Posting result here after I tried it.

After some trouble I managed to install Linux Mint, Preemtive RT and compile linuxcnc. Touch screen works fine, but it is always a new problem. Now the latency is sky-high. On Debian with preempt it was around 20 000 if I remember correct, now it is almost 8 000 000. I have tried to turn off 3 out of 4 cores with "echo 0 > /sys/devices/system/cpu/cpu1/online", but no difference. I have no idea where to look to improve this now

uname -a = Linux FS3MG 4.1.5-rt5 #3 SMP PREEMPT RT Tue Jan 3 18:25:07 CET 2017 x86_64 x86_64 x86_64 GNU/Linux
I'm using a Asrock Q1900DC-ITX mother board.

Any one having any idea???


edit:
Thought it might be memory, but it looks ok.
MemTotal: 3747500 kB
MemFree: 1942444 kB
MemAvailable: 2683328 kB

Disabling the power saving stuff in the bios can help. I've seen similar latency when using the on board wifi on a J1900 PC. Replace it with a USB wifi dongle.
