Hey Nixers,

Managed to get an ultrawide monitor for xmas (21:9 2560x1080 LG 29UM67 29") and spent some good time fiddling with Xorg.conf.

I thought those days were over...

After messing around with modelines and an abundance of settings in Xorg.conf, I managed to get my native resolution working... at 30Hz. It's not the best experience, but its better than the highest default supported Xrandr mode of 1920x1080 at 60Hz. For the record I am running xf86-video-ati on Crux 3.2.

The problem is that if I try to run my native res (2560x1080) at 60Hz (also tested at 55Hz), my monitor is not able to display the desktop correctly; there are several artifacts and the framebuffer is completely jagged.

I'm curious to know if anyone else has any advice or info on getting ultrawides to work. I've been doing a lot of google searching to see if there is anyone else who has a problem similar to mine. It seems like they did, initially. Xrandr wasnt detecting their native resolution and all they had to do was set a modeline.

Thanks guys, hope you're all doing well.

A quick update, I managed to get up to 40Hz on my native resolution of 2560x1080. For reference, here are the working modelines, respectively:

2560x1080 @ 30Hz

2560x1080 @ 40Hz
