An elderly computer of ours has stopped working. When it's turned on, it gives an error of "unsupported display" - this is normal for us and happens because the graphics card can't render the splash screen. However, now it just stays stuck at that error message and won't boot.
I booted a live CD and looked over a bunch of log files but none of them have entries from today, the day the problem started.
Is there any way to figure out what the error on the hidden splash screen is?
