The official packages are still being built against 14.1. That usually doesn't matter but kernel modules sometimes have compatibility issues and 'sometimes' becomes 'usually' for some graphics drivers. There is an effort to make official packages that are built against 14.2 before 14.1 is released but I don't recall how to switch to those repositories. Building the graphics driver yourself should work and downgrading to 14.1 until it goes EOL and the next package set is built would also work. If you try either of those without success then I'd recommend finding out what graphics chipset and driver is in use for further reporting. For x86 if you are UEFI booting then vt is the only choice. Legacy/CSM BIOS booting can still choose vt or the older sc. I have different hardware (nvidia) but found some terminal graphics bugs are resolved with hw.vga.textmode=1 . Using that setting loses mouse support but I think text flowed faster at the terminal. Probably lost font control too. > Does anyone know how I could begin to debug this? Thanks!
