UPDATE FROM MABULA
I have had a very rough 2 months unfortunately health wise. I was struck 3x in a row with bacterial infections. The second infection occurred  after a routine hospital checkup and I became very sick. I had to rest and take a lot of antibiotics. Once I was recovering and restarting work 1 month ago, I again became sick. The infection was not yet gone, so even more antibiotics and rest was needed. Needless to say, it took a lot of my energy and I needed a lot of rest.
Finally, the infection is really gone and my energy is coming back step-by-step now and I have started work again. I am terribly sorry to have kept you waiting for support. I will address all outstanding questions and e-mails step-by step and will be on the forum daily from today.
APP 2.0.0-beta47 will come soon as well, a lot of work was already completed before I became very ill, so the release is also nearly ready for you. Beta47 will be much faster actually. Many workflows will be more than 2x faster, mosaics can even be 10x faster than before because registration really received a major boost... all compared to beta46. Â Before I release it, I will make sure that everything is working properly and then I will release it.
Hi Mabula, I have installed APP in my Ubuntu 18.04.
I noticed that.
The OpenGL symbol is always yellow after an update from OpenGL 3.0 to 4.5 so not active. A mouse click on the symbol does not cause a
change.
Hi @minusman,
If the OpenGL symbol is yellow, it would usually mean that there is a problem with the OpenGL driver, for some reason the OpenGL initialization fails.
Perhaps you can elaborate about:
"The OpenGL symbol is always yellow after an update from OpenGL 3.0 to 4.5"
So, I assume you update your graphics drivers and then OpenGL in APP is broken ?
Can you tell me which graphics card and which OpenGL drivers you are installing?
Kind regards,
Mabula
I have a Radeon Fury X graphics card. The driver is the Mesa 18.3.3 which is included in the Padoka Stable PPA( https://launchpad.net/~paulo-miguel-dias/+archive/ubuntu/pkppa).
With best regards,
Henry
Hi @minusman,
Okay thanks, we need to do some testing and get some output from your Ubuntu + Mesa 18.3.3 installation to solve this.
Can you open a terminal/console and run the glxinfo command?
Can you send me all output?
I will try to create a test installer that will extract all output of the opengl initialization on your computer, which should tell us a lot more 😉
Mabula
Hi @minusman,
I just got confrimation, that there is an issue with the opengl library that APP uses and the latest version(s) of Mesa under GNU Linux... so you must be triggering this.
I know that this issue is being dealt with.
So for now, I suggest, you use a bit older Mesa version on which the OpenGL initialization does work. In the meantime, I'll communicate with the opengl library people on what I can do to speed-up the fix. Okay?
Kind regards,
Mabula
It's okay,Mabula. It's not so bad at the moment, the CPU rendering is luckily still available. I need the latest Mesa version for other software that needs it. I can make a screenshot only at the weekend.
With kind regards.
