T510 problem with panel

HP Recommended

Hi All,

 

I have some issues to solve.

 

I'm using HP T510 Thin Client (OS: ThinPro) and it works great with standard Dell monitors. The problem appears when I want to use automation panel. The panel have DVI-D input. It doesn't work when it is plugged solo. And doesn't work when it is plugged into DVI-D slot, even when monitor is plugged to other slot. It is strange but it works only when it is plugged into T510's DVI-I slot and Dell monitor is plugged into T510's DVI-D slot. However, it doesn't work like I want because when you disconnect monitor, the panel disconnects as well.

 

What was done:

 

I figured out that it might be some DDC, EDID problem so I removed two pins from the cable (DDC Clock and DDC data). Now the panel can work solo. However, to display properly, the changes in xorg.conf file must be done (added modeline, horizsync and vert refresh). Suprisingly it still doesn't work on DVI-D slot. I tried to disable EDID in xorg.conf file but none command I found on the Internet works (UseEDID, IgnoreEDID, NoDDC, etc..).

 

Questions:

 

How can I have solo plugged panel without removing pins from cables?

Why do DVI-I and DVI-D slots work differently? It shouldn't be any difference because I'm using DVI-D cable.

Why panel's EDID isn't read properly by T510? How can I change it?

 

There are some xorg.conf and log files:

 

Default configuration and normal DVI-D cable:

My configuration and normal DVI-D cable (failed):

Does anybody have any idea how to solve it?

Hello Piotr_0

 

I am having a similar problem connecting a T510 to two High Def TV's via DVI to HDMI cables.  The DVI-I port will work, but the DVI-D port will not.  The HP boot logo shows on both while it's booting, and I can get a console session with either port, but X will not play with the DVI-D port.  I have many other T510's connected to two monitors via dvi, this is the first time it has been an issue.

 

I have experimented with cutting the two pins from the cable that carry the edid information and have tried different xorg.conf settings as well, but no joy yet.

 

If you succeed, please post back here.  If I succeed, I will do the same.

Update

 

I have found that rolling back to firmware T6X43101 REV. 1 (19 Apr 2013), sp61603.exe, corrects the problem.  I also tried copying the xorg.conf file from the working older firmware to the latest 4.4, and it would not work.  I believe that this isolates the problem to the video driver, Xorg, or the kernel.

 

Side Note: I have found that I cannot use the new 5.X firmware because it dowsn't support our smartcards.

Thank you J-Dubya for your answer!

 

I tried older firmware as you said and there is actually some progress.

 

I can use panel solo now plugged into DVI-D port. Weird, but this is the port which didn't cooperate with panel at all. Port DVI-I doesn't work the same way though. When I want the panel plugged to DVI-I I must plug my Dell monitor during system start. Then I can plug and unplug whatever I want.

 

So it's still not perfect but it's something. Unfortunately my touchscreen stopped working. Apparently ideal system release doesn't exist...

 

I started looking for a system version that either do work with the panel and with touchscreen.

 

I found out that the crucial changes were made in version: T6X44017 REV. 1 (14 Nov 2013). Touchscreen is now back but the panel problem is back as well. Also in previous versions I could plug and unplugged monitors at any moment, now once unplugged monitor can't be plugged again. The same problem was in version: T6X50034 REV. 1 (24 Jun 2014 ) which I had at start. Release note says there is some new feature: "Ability to preserve user's display resolution and/or user's Network settings while a profile is being applied." Maybe this is it. And there is note: "Adding the driver for Quanta touch screen.". So it explains touchscreen behaviour.

 

I wish I could mix the features of both versions. Can it be done?

 

 

Edited:

I found touchscreen driver for linux but it requires Java runtime environment (JRE). Is it possible to install this?

Piotr_0 ,

 

With the resources that the T510's have, I would be hesitant to try to get JRE running on there.  You would have to compile it for the T510, etc. 

 

I investigated a little further into the two firmwares I'm working with.  I was hoping that they had the same kernel, etc, but no.

 

The 4.4 Firmware uses:

Kernel 3.8.13-hp (a custom compiled kernel)

via_chrome9 module for the graphics

 

The 4.3 Firmware uses:

Kernel 2.6.32-33-generic

and the only module that seems associated with graphocs is vga16fb..

 

Since they are different kernels, the modules cannot just be copied.  This goes for the touch screen modules too, I'm afraid.  Fixing this gets very involved from here.  I think it's possible, but difficult.  The process would be something like extracting the info from the squashfs, building the modules on a virtual machine, and putting everything back together.  Unless you are very knowledgeable at it, it's a days/weeks kind of thing.

 

Have you tried the new 5.0 firmware yet?

Yes, i tried the 5.0 firmware. It seems that all version newer than T6X44017 REV. 1 (14 Nov 2013) are alike.

 

Unfortunately I'm not a linux expert so I think I'll give up. I'll wait for the anwer from hp support but I honestly doubt they can solve it.

 

Thank you again J-Dubya for answer. You helped me a lot.

Hi All

I see no mention of what has been entered within "Display Preferences" and whether a secondary display profile has been created and to which Port it should be assigned to.

Are seperate display preferences being used for DVI-I and DVI-D ?

@ Piotr

I believe you have a case open with HP

They request you send them your xorg.conf file

Hi K.Garrett,

 

Before digging into xorg.files we thought that it is something related with Display preferences but didn't get any results.

 

We tried default Display preferences, then we tried to switch primary display beetwen DVi-I and DVI-D,  we tried to set other values  than 'auto' and also we tried to create two display profiles with the same and different properties. No effects.

 

It is worth to add that resolution changes doesn't affect the panel. We had to do it in xorg.conf file.

 

Thank you for information, I answered the support.

@ Piotr,

 


Were you ever able to slove this issue?  If so, how?  Did HP support find a solution?
