[thijstriemstra]

what device are you using? can you link the datasheet or seller link?

HIbranded from china probably, part number is cm009605v4it works with arduino, I was retesting with Linux ubuntu

Identical behaviour on latest Fedora Linux/x86_64 6.3.11-200.fc38.x86_64 Kernel
and 2.42" ssd1309 i2c 128x64 module from here : https://www.aliexpress.com/item/1005003091769556.html
I needed to short D2 as explained to get it visible at 0x3c.
The same example (terminal.py) works fine with two other smaller i2c modules based sh1106 and ssd1306 chips.
However with this one, starts and fails after a second-two working.
Typically: ... i2c_rdwr
ioctl(self.fd, I2C_RDWR, ioctl_data)
OSError: [Errno 5] Input/output error

FYI, the module as HW on same host works well with this driver: https://github.com/armlabs/ssd1306_linux

Anyone can test this on Raspberry Pi OS? I don't have such a device so won't be able to test..
