"OpenLP has stopped working" when OpenGL not installed on Windows 8.1

[Chris Hill]

I recently upgraded a laptop to Windows 8.1 and experienced problems starting up OpenLP.

After the initial setup phase, when attempting to start OpenLP. I got the error "OpenLP has stopped working" and the application crashed. This worked fine under Windows Vista.

After some investigation, I discovered that OpenLP was crashing after 'Init done for SlideController' in the debug log (see below). I checked out the log on a working machine and saw that normally after this code in openlp.core.ui.maindisplay is run, including the following code:

        if not is_macosx():
            self.setViewport(QtOpenGL.QGLWidget())

This rang a bell as I had struggled to get other OpenGL apps working on the laptop post install. After checking the Intel website, I discovered that the laptop had an Intel 965 chipset, but the default drivers that come with Windows 8.1 do not support OpenGL. I downloaded the last Windows 7 set of drivers available for this device (win7_1512754.exe) and installed them on the laptopm even though they were 'older' than those included with Windows 8.1. After rebooting, the problem went away.

If this happens again it is worth people upgrading their graphics drivers if they are still using the built-in Microsoft ones (if the device name contains the words 'Microsoft Corporation' in Device Manager). It would be helpful if OpenLP could detect if the current drivers support OpenGL properly. If they don't, it probably shouldn't attempt to initialise the viewport with OpenGL enabled, to avoid the crash happening for others.

Hi Chris,

Thank you for bringing this to our attention. We'll include it in our trouble shooting guide.

[Tomas Groth (tomasgroth)]

This has now been added in the documentation that will be released with OpenLP 2.2. Don't know if we can do much more...

[Chris Hill (minkus)]

Interestingly enough I had a go with a similar scenario in Windows 10 (using the built-in drivers) and it seemed to be OK.

I guess the Windows 8.1 default OpenGL renderer is different to the Windows 10 one. It may be a Windows 8 only issue (which might mean it goes away pretty quick?!? :)

Thanks for putting it in the docs anyway.
