BBB Debian LXDE 3.14.19-ti-r30 4DCAPE-43T uDev.txt settgins large dialog boxes and Virtual Screen

I should be able to find the answer to this, but I can’t.
Almost all the dialogs for lxde are larger than the LCD screen at 480x272.
Is there a way to tell Debian I have a small screen and pop up scroll bars to reach the off-screen parts?
When I tab or arrow key off screen, it just goes off screen and I can’t see it.
I assume there is a way to scroll the virtual screen (I think CTL-PGUP / CTL-PGDOWN, for CTL-ARROW KEYS should have worked).
I noticed a little icon at the bottom with a monitor with an exclamation point in it, “Screen Lock”, does that prevent scrolling?
If so, I can’t find a way to interact with it to tell it to allow scrolling.

On the page http://elinux.org/Beagleboard:Capes_3.8_to_3.14#4dcape-43

I see:

dtb=<device>-4dcape-43t.dtb
screen [x]
backlight (gpio) [x]
backlight (pwm) [ ]
touchscreen (4wire) [x]
buttons [x]
led [x]

Is this where I set up the screen extents in uEnv.txt?
What goes in the [x] values?
I could’t find a concrete example with google.
Is there a more detailed page somewhere?

Thanks in advance.

You don't, set them in xorg.conf

feature of the cape that's been tested/works... as you can see, i'd
like to get pwm based backlight to work, but haven't yet..

I could't find a concrete example with google.

Regards,

Unless I’m way off base, it looks like the LCD driver is using the frame buffer to determine the resolution of the screen.
Here is my xorg.conf file:

Section “Monitor”

Identifier “Builtin Default Monitor”

EndSection

Section “Device”

Identifier “Builtin Default fbdev Device 0”

Driver “fbdev”

EndSection

Section “Screen”

Identifier “Builtin Default fbdev Screen 0”

Device “Builtin Default fbdev Device 0”

Monitor “Builtin Default Monitor”

DefaultDepth 16

EndSection

Section “ServerLayout”

Identifier “Builtin Default Layout”

Screen “Builtin Default fbdev Screen 0”

EndSection

From what I can find, the resolution is set by uboot when it starts up. (Based on this page http://developer.toradex.com/knowledge-base/framebuffer-(linux)#Framebuffer_Boot_Configuration)

The screen displays properly, so it knows the resolution of the LCD cape.
However, the dialogs are just too big to fit and there appears to be no way to scroll the display.
Do I need to configure a virtual display? Will that pop up the scrollbars? Or allow the hot keys to move the window in the virtual space?

Perhaps I should clarify,
Is changing the font size the only option to get the system dialogs usable on the display?
I Like the font size, If it goes too small to fit everything on the screen, it will be unreadable.
I’d be happy with a virtual screen that scrolls to the active field or allows the viewport to be moved using hot keys or mouse drag.
