[Solved] Grey screen then lock screen after editing display settings

j.tran4418 · 2015-10-17 17:10:07

New to xfce. Trying to set up dual monitors but whenever I edit my display settings from mirror to side by side and apply it, my screen goes gray and after clicking I'm sent to lock screen. After logging in again from the lock screen I'm hit with the grey screen again and it just cycles like that forever. I have to open up a tty and delete my ~/.config/xfce4 folder before it finally works again. I tried editing my settings with arandr to the same result. Really frustrating, any help would be amazing. I also can can disable screens from the display settings but reenabling them or applying any other change results in the grey/lock screen cycle.

Hello and welcome.
Which distro are you using and what version of Xfce?

On first read, it sounds like a graphics/X configuration problem. What does the following command return:

xrandr -q

Also, what graphics card do you have and what types of monitor connections are they?

What happens if you try to set it up manually:

xrandr --output VGA-1 --auto --output DVI-D-1 --auto --right-of VGA-1

Tried that, and tried it using arandr, all are met with the grey/lock screen

This is a fresh install, too, so I hadn't messed with any X settings.

To be honest, I don't think this an Xfce bug (since the xrandr command also creates the same result). I think its related to the configuration of your video card. Have you tried any other DEs on this device (kde, gnome, etc) and do they work?

You might find some helpful information in your /var/log/Xorg.0.log.old file. Maybe an error message relating to the running of the xrandr command.

I looked at the log but couldn't really find any leads. I did finally solve my problem my switching to the proprietary nvidia driver over Nouveau. Used this guide: https://help.ubuntu.com/community/Binar … wto/Nvidia

Thanks for the help!
