I'm considering buying a ThinkPad X1 Extreme Gen 4 that comes pre-installed with Windows. So I looked at Ubuntu's list of certified hardware to see if the laptop is certified/compatible with Ubuntu. After finding it on their list, I clicked on the link to read more about it and got the following information:
Pre-installed in some regions with a custom Ubuntu image that takes advantage of the system’s hardware features and may include additional software. Standard images of Ubuntu may not work well, or at all.
So it seems like the hardware is only certified if I buy it pre-installed with a custom Ubuntu image, which isn't available btw. But it says the exact same thing on every other listing I checked. So I'm wondering if anyone has found a laptop that is certified with a standard Ubuntu image?
PS I'm not interested in System76 hardware right now.
