Hello, I have X-Plane 11.30
I've just updated to version 2.5.11.0 and now I see a completely black screen in both the GTN750 and the GTN650.
I tried with 2 different aircrafts that previously worked without problems, the Cessna 172 GTN mod (+ REP) and the Carenado CT210M Centurion II (+ REP).
I have not made any changes to the .ini from the previous version that worked fine.
Black screen both in the cockpit and in the windows popup and also in VR mode. I also tried to change the power options without any result.

Hi,

can you please post the content of the RXP log files? (see User's Manual for file/path)

 

Thanks for the quick response.
I do not see errors in the logs, this is the content of rxpGtnSim.dll.log:

and this is of rxpGTN.xpl.log:

Thank you for the logs, they don't show anything peculiar. Can you please:

1) Exit X-Plane

2) Open the RealityXP.GTN.ini file in the aircraft folder with notepad (or any text editor)

3) Add the following 2 lines:

[GTN_750_1]
DebugValue = 1
LogTrainer = 1
...

NB: under the [GTN_750_1] if you are using a GTN 750 Unit 1.

4) Reload X-Plane and the aircraft

5) Post newly generated log files content?

Well, these are the new logs.

Ok, this helps!

Somehow it fails to locate the non volatile memory folder.

Can you please let me know what do you have in this folder:

C:\ProgramData\Garmin\Trainers\GTN\nonvol\

Yes, this is the content

Ok this seems to be correct as well.

Do you run with Trainer 6.50.1 or 6.21?

Do you use any environment variable to redirect trainer paths or not?

Can you please cross check the following registry keys and let me know where they point to (if you are comfortable with regedit):

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Garmin\Trainers]
"DataPath"="C:\\ProgramData\\Garmin\\Trainers\\"
"BinPath"="C:\\Program Files (x86)\\Garmin\\Trainers\\"
"DBDataPath"="C:\\ProgramData\\Garmin\\Trainers\\Databases\\"

Edited January 12, 20197 yr by RXP

The trainer should be the 6.50.1

This is the export for the HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Garmin\Trainers key of registry:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Garmin\Trainers]
"DataPath"="C:\\ProgramData\\Garmin\\Trainers\\"
"BinPath"="C:\\Program Files (x86)\\Garmin\\Trainers\\"
"DBDataPath"="C:\\ProgramData\\Garmin\\Trainers\\Databases\\"
"ShortcutKeyPath"=dword:00000001
"BootstrapperLocation"="C:\\ProgramData\\Package Cache\\{0cf89a63-832f-4334-96d5-46ff0c3bfff7}\\GarminTrainerSetup.exe"

On the same day I also updated the NVIDIA drivers by installing the latest available (417.35). I hope the problem does not depend on this.

 

What about this:

And can you also tell me what's in:
C:\Program Files (x86)\Garmin\Trainers\Packages\GTN\data\nonvol\

I don't think this is an issue in itself but it might be. However in this case I'd expect the RXP log files, with DebugValue = 1, to output any video card related error.

Nevertheless, do you also happen to have both Intel and Nvidia GPUs in your system? If this is the case, you might want to review the RXP GTN User's Manual troubleshooting section for this.

No, I don't use any environment variable

Thank you for your patience, Jean Luc, tomorrow I'll try to recover the previous drivers to give an attempt, if there is no other solution.

 

Hi Jean Luc.  I updated to the latest version and now get the black screen again.

Okay, I uninstalled the trainer and reinstalled it.  Here are my new logs:

When installing the trainer there was no option to install the 750, only 3 other models.

Thanks,  Howard

The error seems to point to a problem either reading this file:

C:\Program Files (x86)\Garmin\Trainers\Packages\GTN\data\nonvol\sys_nand0

Or writing any of these files:

C:\ProgramData\Garmin\Trainers\GTN\nonvol\sys_nand*

The later may be due to a corrupted file. I'd suggest you try:

1) rename: C:\Program Files (x86)\Garmin\Trainers\Packages\GTN\data\nonvol
     to backup: C:\Program Files (x86)\Garmin\Trainers\Packages\GTN\data\nonvol.backup

2) open the simulator and load the aircraft with the GTN

3) see if it creates a new 'nonvol' folder

4) if not, create one manually and open the simulator again

5) see if it creates the sys_nand* file corresponding to your GTN (see user's manual for file names)
