Window: Unable to find any valuable Window provider at all!

[Ed Lipson]

I have a command line python program which works. I want to add a GUI to it and thought to try kivy.

Trying the first example, I made a class out of my startup and added the App class. I get the attached error. Windows 7. I'm not expecting much to happen here except for the kivy App to open. Just a first test before I start making the main line of code 'GUI'.

Looking at some of the posts about this error, I'm not on Android and I can't change company GL drivers, machine is locked down at some level. SO what do I do to fix this? I could do tkinter but I wanted to try this.

Hi Ed, 

Make sure you launch your kivy app in the context of the Kivy virtual environment. Instructions here:

http://kivy.org/docs/installation/installation-windows.html

[Ed Lipson]

I followed the instructions for the SendTo method and got the same results. I had run previously as just kivy.bat script.py.

To make it simpler, I deleted all but the imports and the kivy code:

from kivy.uix.button import Button

class TestApp(App):
    def build(self):
        return Button(text='Hello World')

TestApp().run()

Same error. Then I removed all the imports but kivy. Same error.

from kivy.app import App
from kivy.uix.button import Button

class TestApp(App):
    def build(self):
        return Button(text='Hello World')

TestApp().run()

I tried to run demo\kivycatalog and got the same reslts/error.

[Brent Picasso]

Do any of the kivy examples run, when launched from the context of the kivy virtual environment?  (Kivy.bat)

None of the samples run. I installed this at home (Win8.1) and the all work. I have not tried my script from the office at home.

I did install some python libraries, but I don't see how that can impact this.

[Ed Lipson]

to rule out some other impact I may have had on the python, I unpacked the 1.90 version to a new location, created a new send to for it and tried to run a sample program. It still failed.

I just tried to capture the video stuff from the system and got a warning that the settings can't be changed from a remote session. I have RDP's to the PC. Might that be the issue? I normally use dual, different sized, monitors but only a single one is active during RDP. I don't know how it fits in, but it is an observation.

[Brent Picasso]

Are you using RDP to access the system attempting to run kivy?

If so, RDP isn't supported.  You can try VNC if you can stomach the performance hit.

[Ed Lipson]

Yes, I am remoting to the desktop where the code is hosted and running. Do you mean rdp is not supported for development or development and runtime (if I build an exe with pyinstaller, will it run rdp)? We run a lot of citrix/rdp users. I do it myself when I am remote to the office. This may be a real roadblock for me. But I always have tkinter. just more work. Is it on the development horizon?

Thanks, now I know what the problem is.

[Brent Picasso]

Yes, not supported due to the opengl 2 requirements.

However, it's really bizarre. If you launch the app using VNC, close VNC client and re-connect using RDP, I've observed the app will still be running fine in RDP. Not sure what kind of black magic is behind this, or if there's some overly stringent check upon startup.

I have no idea what the Problem is.
 

[Ed Lipson]

Windows 10 has Open GL 4 support. I've asked if they are backporting, don't expect a response and if I do get one I don't expect a positive answer. Company moves slowly, just got Win7 at the last moments before WinXP went off support. Win10 could be a while. 

I'm not sure if I can build it as a dual mode app, if under RDP don't use Kivy. I think I still have to bootstrap it though, so I'm not sure if it is possible. I may need two separate binaries. Time to experiment.

I have a similar Problem with the Cutbuffer:

I suspect, after a quick Google search on what cutbuffer is, that it is also related to how you are running. I know I have very strange behavior with my Clipmate program if I try and let it interact across the RDP session from the local PC to the remote PC. When I shut off the option of having it interact both copies run OK separately on their respective systems. Just a guess.
