Ubuntu Yielding Noisy Black/White Scans
I did a fresh install of Ubuntu 14.10 today with Cinnamon as a desktop and am pleased with the interface.
I noticed something when scanning some documents in lineart mode, though: the resulting images had a ton of noise, noise that I did not see in scans prior to my upgrade. After snooping around the various options in the gscan2pdf application, I stumbled upon this one which, when toggled, causes the noise to disappear: Disable dynamic lineart. After checking that box, my scans seem to be noise free.
