RE: Building OSCAR Ubuntu 20.04
I installed the nvidia-cuda-toolkit and cuda 10.1. Thought maybe some graphics stuff might be missing and perhaps that would change something.
Did a $ make distclean, which by the way, does not remove the subdirectories /html and /translations in /build/oscar.
Then
$ qmake ../OSCAR-code/OSCAR_QT.pro
$ make -j4
-j4 speeds up things considerably!
Lo and behold OSCAR now runs! Don't need BROKEN_GL. Curiously, the OSCAR debug window reports
Code:
10432: Debug: Operating system: Ubuntu 20.04.1 LTS
10432: Debug: Graphics Engine: 4.6.0 NVIDIA 418.152.00
10432: Debug: Graphics Engine type: LegacyGFX
Is
LegacyGFX correct?
In any case, the graphics seem to be crisper (and faster) than BROKEN_GL. The graph traces are sharper as well.
RE: Building OSCAR Ubuntu 20.04
Sounds like your running the correct graphics driver now
RE: Building OSCAR Ubuntu 20.04
It's saying LegacyGFX when running because that preference is sticky. Once you turn it on, it stays on until you turn it off in preferences:
Preferences > General > Desktop OpenGL
(I'm betting yours still says "Software Engine".)

RE: Building OSCAR Ubuntu 20.04
sawinglogz, Yes you are correct. Just changed it to OpenGL. The app restarted and it's even better now. Now running OSCAR 1.2.0-rc.2+master-1faaf625-plus (linux x86_64)
Hah, now I need to take out the sleep commands I put in for debug! Must of added over 10 seconds of delay.
Yeah! Commented out my sleep statements. Now in OSCAR in a blink of an eye!
