Can't access panel, how do i reset display resolution?

right click on desktop pulled up half a menu which had a terminal for a choice. tried xrandr and stumbled through the help menu on it and finally got the screen size back. Still having issues with some windows not showing the bottom of the window such that important buttons like 'OK' can be selected. This is a mini-laptop with a 10" display. 1024x600 still leaves some windows with bottom edge below the horizon.

When then happens, press and hold the Alt key, then you can click and drag the window with your mouse.

There is a script called newrez

With this one you can change the resolution on the fly virtual (tunelled) with a terminal command - or even with a starter.

The Script could be downloaded here :

https://dl.opendesktop.org/api/files/do ... rez.tar.gz

You have also to install zenity.

Once downloaded and extracted - save the script to: and make it executable.
rename it from newrez.sh to newrez (without extension)

Restart the System.

Then you can change the resolution with a terminal command ..... for example: and back again to original : It is also possible to do this within a starter.
As you are in Xfce you can do this easy with a quicklauncher:
Quicklauncher is part of the which could be installed.

The commands for the quicklauncher see below :

Newrez Quicklauncher
command newrez 1280x750 name Display virtual to 1280x750
command newrez 1024x600 name Display to normal 1024x600

I installed the Script on several netbooks with the same resolution as yours - and it works fine :
finally, programs like libre office are also completely visible

It is even possible to integrate a command into the Start-Programs - so that you can start the netbook with a higher resolution.

And : dont worry - as it is only virtual it cant destroy the display e.g.
