Created attachment 308130 [details] the purple screen The photograph of how it looks is in the attachment. I have a GTX 970 connected via DisplayPort. When launching any LiveISO in normal mode, I get this screen. HDMI works, although stuttery. The GPU is completely fine, as I game on it on daily basis. In some distros (tried Linux Mint) starting with nomodeset makes the display working. On Arch-based distros I get stuck at "Reached target graphical interface" in the TTY.
Please report here: https://gitlab.freedesktop.org/drm/nouveau/-/issues/ To be honest nouveau is quite flaky, so I'd recommend using the proprietary driver instead.
