Many years ago friend gave me broken SCSI scanner. It always said "paper jammed". I thought I just short or remove the paper sensor but it wasn't simple kind of sensor, there were two and from the delay it decided whether the paper was jammed or not.

So I downloaded the source code of SANE, find the offending error message, commented it out and scanner worked without issue.

I had one of these stupid AMD graphics cards (I think from the Evergreen generation) where the GPU/memory clocks would be locked in at the highest frequency whenever you had a second monitor plugged in. Apparently some sort of graphical glitches would be possible otherwise. In their infinite wisdom, AMD decided it was worth an extra 20W of baseline power consumption to avoid these glitches. (I am told they still do this as of today).

So I went the radeon kernel driver, and simply commented out that part. Never had a single glitch for the entire lifetime of the card, but oh god I did enjoy the silent fan-free operation.

And people wonder why I'm a staunch fanatic of free software.
