My Emulation Station keeps crashing saying I need to make sure my gpu_split is set high enough and/or switch back to carbon theme. Can someone help me dial this in? Any thoughts or suggestions are much appreciated as I dunno what's causing my ES to randomly keep crashing.

RP3b (not sure if its a B+ or not. Its a model B v1.2 from 2015) running RetroPie 4.5.1 I mostly use pixel-metadata theme. I scraped for metadata and have a video, image, thumbnail, and marquee for almost each ROM (1500+ games) I have a 128GB SD card that's only about 50% filled atm. Setup from a stock RP image about a week ago.

You can use vcgencmd to get the memory:

pi@raspberrypi:~$ vcgencmd get_mem gpu
gpu=128M

Alternatively use raspi-config non-interactively, which uses vcgencmd underneath and pulls out just the number:

pi@raspberrypi:~$ sudo raspi-config nonint get_config_var gpu_mem /boot/config.txt
128

  • You are answering how to get the memory but the question was how to set it. As far as I know you can set it in /boot/config.txt. If you know how you may add it to the answer? – Ingo Aug 30 '19 at 8:57
  • You can set it with e.g. raspi-config nonint do_memory_split 256 – ben_nuttall Aug 30 '19 at 12:25

    You should add the information to the answer. – Ingo Aug 30 '19 at 20:19
