Windows larger than display height

Hi - I have a Raspberry Pi 2B powering official 7 inch touch screen using 2 jumper wires per YouTube tutorial.
Raspian-Jesse installed with NOOBS is updated & upgraded as of today 2/19/16.

My Problem is that the pop-up windows are too large for the 7" screen height - I can not see the OK / CANCEL buttons.
For example: Menu > Preferences > Appearance Settings, I can not even see the bottom of the window.
I right-click on the top-left icon however resize does nothing.

Newbie here - needing some guidance
Please be kind.
Thanks, Jim

This is the old problem of software authors making untrue assumptions about screen dimensions.
First thing to try is CTRL+Left click-and-hold, usually this turns the mouse pointer into a "hand" and you can drag the window around while you keep the mouse button pressed. Quite what the equivalent actions for a touch screen are I'm not sure, mine isn't to hand right now.

A workaround is to add to config.txt:

Code: Select all

framebuffer_width=1200
framebuffer_heigth=720
(you can try different numbers).
This results in a larger framebuffer that will be scaled down. Might look a bit less sharp, but you have more room for windows.

Hi and thanks for the quick reply:
I used:
framebuffer_width=1200
framebuffer_heigth=768
these match exactly the ratio of the 800x480 7" display.
Now I can see the full pop-up window

My problem now is that the text in the terminal window is so small I can barely read it.
Is there a Linux equivalent to the Windoze CTRL+/- to zoom in/out on a screen?

This is RESOLVED to my satisfaction.

On terminal type sudo nano /boot/config.txt and press enter.

1280x768 is proportionally the same as 800x480 - set it to that, reboot and now you can see the full pop-up and adjust.
Then set the screen to 800x480 after the setup is complete to your satisfaction and reboot.

I edited & saved the config file to uncomment the framebuffer_width=1280 and framebuffer_height=720 so when I rebooted it should have taken effect. I need to be able to accept the changes to the appearance. I am using the sudo nano command with Pi3, Adafruit PiTFT Plus, Jessie Rasbian OS

I am very new so plain English would help. :)

It's actually ALT+Left Click. Sometimes it takes several tries befor it takes hold. Can nearly push the window off the top of the page then. Thanks that will really be helpfull on another Pi with a 2.8" screen.

Change the font size. Had mine down to 7 before the framebuffer change. Made it 8 afterwards.

Use CTL+O (the letter o) to save before exiting Nano. You should be able to find a tutorial for your display on learn.adafruit.com. That's what I used to set up my little display.
