Trying to get my Datalux touchscreen to run as a full MD... Almost successful...

[jondecker76]

I have been using all-in-one industrial 15" Datalux iPix touchscreen tablets running Win XP for my orbiters. Now that I have replaced them all with the WebDT 366's, I thought that it would be cool to get these to run as full MD's running UI1 (this way they will still appear like the same orbiter, with the added benefit of being able to watch video and listen to audio.




The unit network booted just fine, and I used a USB mouse to get through the setup wizard. It also boots to UI1 with no problems. However, some things are not working:
1) The touchscreen is not working. It is a 3M Microtouch, which is well supported in Linux. After installing the appropriate drivers and editing xorg.conf, the touchscreen will work (though in bad need of calibration) until the last stage of orbiter loading, then quits working.
2) Video playback is extremely slow and jerky - maybe around 15 FPS.. The unit has an embedded Silicon Motion LynxEM+ craphics chip, 256MB RAM and a Pentium III 700MHZ processor..  I'm wondering if the processor is just too slow....
3) Sound does not work at all. While looking into this, I noticed that in XP's device manager, it lists the sound card as:

Code: [Select]

Crystal WDM AC'97 420X Driver for 440MX
However in linux using lspci, the sound card is shown as:

Code: [Select]

http://Intel Corporation 82440MX AC97I have to research this part further - sound was the last problem I thought I was going to have


The photo screensaver works great though, and is another reason why I want to net boot these as full MD's (plus I can put one in the kitchen and in the bathroom so I don't miss any Sunday Night Football!)


Anyways, I'm going to keep trying to get these to work well as full MD's, so if anyone has any suggestions for me I'm all ears. If I can't get a good suitably fast MD out of these, I'll probably compile a linux orbiter for them and see if I can get Photoscreensaver running on them as well. But I'd much rather see these being full MD's

Ok, i guess I'm going to try to get this working one thing at a time.

first up... Sound card. LSPCI shows it as:

Code: [Select]

00:00.1 Multimedia audio controller: Intel Corporation 82440MX AC'97 Audio Controller

Alsamixer shows the following information:

Code: [Select]

Card: Intel 440MX
ChipL Cirrus Logic CS4201 Rev 5

I've tried everything I can think of in alsamixer....
I've tried to modprobe snd-hda-intel and rebooted with no luck.

Any ideas? Alsa and soundcard config definitely aren't my strong points

step 1 complete! I have full sound!

Oddly enough, I took the unit apart to replace the CMOS battery, and noticed that the plug from the speaker was not connected to the 2-pin header on the motherboard. Connected it up, and I have sound!

next step is to get the touchscreen working.

last step will be to improve video performance (its very jumpy, i suspect from the 256mb ram. I just ordered a 512 sodimm for it - hopefully that helps.
