Screen resolution wrong after suspend

Question

OK ladies and gents I'm a Gentoo (portable) and Arch (desktop) refugee so I'm still getting the feel for Ubuntu so bear with me. I installed 14.04 on my desktop along with fglrx 99% of things work fine after a bit of re-leaning my last problem is that after suspend my screen resolution resets not amount of my tinkering has fixed it. what futzing do I need to do with the AMD drivers to keep my screen resolution?

I'm not sure what is your desktop problem, but you can use this solution to get rid of this issue, run below command in terminal:

xrandr

It's tell you what resolutions your monitor supports.

Then create a bash script (e.g "restore_resolution.sh") with this lines of codes: (put your resolution after xrandr -s)

#!/bin/bash
case "$1" in
    thaw|resume)
        xrandr -s PUT_YOUR_RESOLUTION_HERE
        ;;
    *)
        ;;
esac
exit $?

move the file to this path:

/etc/pm/sleep.d/

and make sure it can be execute:

sudo chmod +x /etc/pm/sleep.d/restore_resolution.sh

it should fix your problem, after resume this script will be run and fixs your resolution.

xrandr is for multi-head is it not? – GermanyChris Nov 05 '14 at 18:46 — GermanyChris, Nov 05 '14 at 18:46
i think it can handle multi-heads too, I'm not sure. – Ravexina Nov 05 '14 at 19:35 — Ravexina, Nov 05 '14 at 19:35
