So, I can make a modeline that works in 15KHz for the Radeon 6670 in linux. But when I tried running switchres with the --xrandr option for puckman, this is what I get:
Error with command line args
seth@Neo-Arcade:~$ switchres puckman --xrandr

I have to be doing something wrong. It's pretty essential to get this working, so I can run games like Kobo Deluxe, Rom Check Fail (which has an odd alsa/pulse issue), smc, and a few others. Calamity, ves, thoughts on what I'm doing wrong both in Ubuntu and Groovy Arcade?
