m4110c Posted September 13, 2021 Share Posted September 13, 2021 Hi there, I have a little problem with my i2c-screen on the Helios4. It was setup according to the Kobol-Wiki and was working right from the start. However after running for some time (in this example it took around 6 hours) the screen is black and empty. Once I SSH back into the helios and restart the systemd sys-oled.service, it works again for some time... "journalctl -u sys-oled.service" gives the following: Sep 13 10:18:38 helios4 systemd[1]: Started System Starting on OLED Display.
