also had probelms with Stretch ( see here) Users of Kodi, another heavy Graphics orientated app. In 2017 we got Stretch (with the 'experimental' VC4 OpenGL Driver), however the 'software emulation' speed dropped to 1/4 ( see here). Next, you need a version of Stellarium that will use the OpenGL hardware driver - which (initally) meant building it yourself.įinally, you will need to solve the remaining 'compatability' issues (things like 'text' display (font rendering), Planets 'flickering' and NEO/Meteor plotting killing the frame rate), however the Forums will usually help you find a solution. So whats the problem ? Well, as usual with anything Linux, it's finding a 'compatible' set of modules that will actually work together to deliver a practical working solution We start with the need for the hardware (GPU based) OpenGL driver (by default, the Pi comes with a cut-down 'OpenGL ES' driver, with full 'OpenGL' supported via software emulation)Ī GPU based OpenGL driver exists, but only for the Pi B2 / B3, however it is (still) 'experimental' - which means you have to install (or 'enable') it yourself (although it's no longer necessary to compile it from source yourself :-) ) These days, even a cheap PC video card will have over 100 'cores', whilst the Pi has only 2 ! However, the Pi desktop is a lot simpler than the multi-display 'aero' garbage used on the PC, so those 2 cores CAN deliver decent graphics speed on the Pi. Stellarium makes massive use of the OpenGL graphics libaries - which, on a PC, will be supported by the GPU hardware on your video card. Pi Stellarium If you must have Stellarium, it can be done, however it's actually easier to get KStars working on the Raspberry Pi - see my previous page Why Stellarium is such a pain to get running on the Pi
