Title: HDMI screen - minor issues
Post by: fb3ajb on July 06, 2015, 07:29:40 pm
Just installed PPM6 onto a Toshiba Satellite E105 laptop.  Love the speed and enjoying the simplicity.  Thank you!

I have a couple of questions about the HDMI output.  I connected a 27" monitor using the HDMI port and the windows and view were were fine.  But...

1.  Is it possible to "extend" the second screen instead of "mirroring" the second screen?  I'd like to use both my laptop screen and the HDMI monitor separately.

2.  The desktop image on the second screen is odd.  There is a rectangle approximately the same size as the laptop screen and about 35% of the screen space in the upper left hand corner that looks like it is sitting on top of the rest of the desktop image.  I changed the desktop image a number of times and the results were the same.

Odd and not critical stuff, but preferences none the less...  Hope someone can help...

Hi fb3ajb,

You might want to install the program lxrandr that you can find in the software repositories of your Peppermint Six installation. Check it out, google (or duck-duck) the use of it. As I recall, it can take care of most or all of your questions. It is what I was using back when I needed to have two displays of different sizes running separate rather than mirrored desktops.

lxrandr is installed by default .. I think what Slim.Fatz meant was arandr

arandr will allow you to position the monitors wherever you like and save the configuration.

You can install arandr by opening a terminal and running:
Code: [Select]
sudo apt-get install arandryou]ll then find it at

menu > Preferences > ARandR

Fire it up

Drag the monitor representations to the side of each other

Layout > Apply

If you have an nvidia or ATI card, and are using the proprietary drivers .. this ffuction may be in their respective control app.

Thanks for the correction, PCNetSpec !!  ;)
