xrandr help

xrandr shows my maximum refresh rate as 144.01 (I've been using 144 in windows with no problem) but when I try to do xrandr -s 1920x1080 -r 144 (or 144.01) i get size not allowed, if I do the longer version xrandr --auto --output DVI-D-2 --mode 1920x1080 --rate 144 my screen just goes black and I have to type xrandr -s 1920x1080 -r 100 to get it to come back, any ideas?

specs: i5 2500k, r390

Re: xrandr help

Welcome to Arch Linux. 

For starters, what are the output of xrandr  with no command line parameters?

Re: xrandr help

That looks rational to me.  Based on that, I'd have expected it to work.   
My system does not have DVI outputs, so I'll leave this to someone who does.

BTW, please use BBCode code tags around program output and file dumps; your readers will appreciate you.
That link is also available under all of the message post boxes on the forums.

Re: xrandr help

xrandr --auto --output DVI-D-2 --mode 1920x1080 --rate 144

Why would you mix auto with a specific mode?

First try

xrandr --output DVI-D-2 --auto

1920x1080@144Hz should actually be the automatic choice (indicated by the "+")

Next: does the  monitor just get dark or does it actually indicate a signal loss (and enter suspend mode or so)?

Re: xrandr help

xrandr --output DVI-D-2 --auto

puts my monitor into suspend mode, and yeah turns off, not just dark screen.

Re: xrandr help

Seems like the monitor doesn't like the generated signal.
Please paste the xorg log and the exact monitor model (bonus point if you can provide a tech sheet ;-)

Re: xrandr help

Sorry pretty new, where can I find the xorg log? Monitor is a cheap korean one I got off ebay a few years ago, never had any problems with it under windows: http://www.ebay.com/itm/X-star-DP2414LE … SwgQ9Vn4lZ
