Sometimes software doesn't know our screens are 'only' 600 pixels high...minus a toolbar. This script allows us to change resolution, beyond capabilities, stressing only our eyes, not the video chips. Open a terminal; enter: Code: mkdir .local/bin to create a directory for a local script.Open a text editor for the two files: Code: medit ~/.local/bin/nxrez ~/Desktop/alilbigger.desktop When the text editor opens; paste into ~/.local/bin/nxrez the followingCode: #!/bin/bash Save the file and paste the following into ~/Desktop/alilbigger.desktop (the other text file):# Marc Brumlik, Tailored Software Inc, [email protected] # Wed Jan 2 05:23:54 CST 2013 # newrez v 1.0 # use xrandr to scale the display to a new resolution # rewriten to handle mouse boundaries when scaled # this requires setting a new resolution to the unused VGA1 device # then scaling that for B display on the LVDS1 device # modified by Moe because he's lazy and doesn't like to type. umask 000 # resolution can optionally be specified on command line newrez=$1 # we MUST be running xrandr 1.3 or higher if xrandr -v | grep "RandR version 1.[012]" then zenity --info --title="XRandR version is too old" --text="You must be running Xrandr version 1.3 or newer!

Hi Moe I'd like to run this very usefull script but I've never done that, so I 'm a bit lost: if I enter in a terminal:mkdir .local/bin the response is : zelda@zelda-AOA150:~$ mkdir .local/bin mkdir: impossible de créer le répertoire «.local/bin»: Le fichier existe I go on , I open text editor medit, I see two files already there:lightdm.conf and libclearkey.so (I remember that I've tried to run a script about password some months ago but didnt succeed). Then when you say: When the text editor opens; paste into ~/.local/bin/nxrez the following I don't know how to find : ~/.local/bin/nxrez from the text editor. Finally, when you say:save , ok but save under what or where ? I'm sorry, I 'm really beginner and most of the time, everything in NX is working so perfectly, then I don't really have to learn how to improve or repair, compare to ...another OS |

Sorry Zelda, "paste into ~/.local/bin/nxrez" is a poor way of saying "create an empty file and put in the following text" Since mkdir: impossible de créer le répertoire «.local/bin»: Le fichier existe (mkdir is the command to make the directory, which you already have. This is ok, and since you tried that password script, it's expected. ) If you enter Code: medit ~/.local/bin/nxrez If the file exists it will open it. If it doesn't exist, it will create the empty file with that name and location (~/.local/bin/nxrez). You can then write, or in this case, paste into that empty file. This is the file you save. After it is saved it can be tested. |
