Hi all,
I have a new LG 25UM58-P 21:9 (2560x1080) monitor. Laptop is a Lenovo Ideapad y460 (specs) (http://www.lenovo.com/shop/americas/content/pdf/notebooks/ideapad/y-series/IdeaPad%20Y460.pdf) Uses an old AMD HD5650m GPU, so using the open source radeon drivers. The UW resolution does not show up in Screen Displays by default, so I'm trying to add it. I've tried a few things that have seemingly no effect so far, except this guide (https://samuelmartin.wordpress.com/2012/05/29/enabling-resolutions-in-ubuntu-12-04-lubuntu-12-04/). However, it's adding the new resolution to my built-in display, and I can't figure out how to switch it over (most attempts leave me stuck in boot after file check and have to rm the .conf)
Please see attachment for a screenshot of Screen Display.

Really sorry if this is a very commonly posted question, I really couldn't find a solution that worked for me (most of them had seemingly no effect at all :()
