Raspberry pi – Access the GUI on pi remotely with VNC

July 29, 2012 1 comment

To be able to access the GUI on your pi remotely with VNC you will first need to install the VNC server on your raspberry pi.

In the GUI left click in the bottom left hand corner on the blue cross  to display the options menu (Like the start button in windows) go to accessories and then left click on LXterminal to display the terminal window

Type in the following command

Sudo apt-get install tightvncserver

The VNC server will then download and install on to your raspberry pi.

When you return to command line type in the following command

vncserver

Once it has vnc has started you should get the following

You will require a password to access your desktops

Password (Enter a password for VNC access)

Verify (Re-enter password for VNC access)

Would you like to enter a view-only password (y/n)? (we say n for the moment)

New ‘X’ desktop is raspberrypi :1

Creating default start-up script /home/pi/.vnc/xstart-up

Starting applications specified in /home/pi/.vnc/xstart-up

Log file is /home/pi/.vnc/raspberrypi:1.log

We now need to set the VNC server to autoboot when we turn the raspberry pi or we will have to log onto pi locally and start the vncserver before we can start using it remotely.

Type the following into command line

sudo nano /etc/profile

Scroll to the bottom of the file and type the following

vncserver :1

(the above command must be put in before the startx command if you have this in the file as well)

You can now reboot and start enjoying your pi remotely though VNC.

(If you want to use your pi locally again you will find that the startx command creates an error when logging on  to resolve this you will need to delete the vncserver :1 from the “/etc/profile” and then reboot)

To see how to setup VNC viewer on your PC so you can connect to your Pi click the following link

How to extract drivers from .exe packages

July 23, 2012 Leave a comment

Pc manufactures  are now using self-extracting EXE packages to install drivers when you down load them from there support websites.

Which is very handy when you have one or two pc’s to install the drivers on to, but not so much when you are building an image for multiple pc’s or trying to look at driver file without having to run the .exe or install it.

This is where the universal extractor software is very helpful tool to use.

Download from here – Universal Extractor

Run the Uniextract Installer and go though the steps of installing accepting all the defaults and let it install

Once installed right-click on the self-extracting EXE files you want the driver from and select uniextract files

Universal Extractor context menu

This will open the Universal Extractor file/destination GUI

The top bar is the location of self-extracting EXE file and the bottom bar is the location you wish the file to extracted to.

Universal Extractor file/destination GUI
(Top bar is location of the self-extracting EXE files)
(Bottom bar is location you want it extracted to)

Left click OK and it go though the process of extracting the files out of the self-extracting EXE and put them in the destination folder you specified and there you will find the driver you needed.

 

Raspberry pi – Setting your pi to a static ip address

July 22, 2012 2 comments

In the GUI left click in the bottom left hand corner on the blue cross  to display the options menu (Like the start button in windows) go to accessories and then left click on LXterminal to display the terminal window

Type in the following command

sudo nano /etc/network/interfaces

This file controls the IP address of the raspberry pi and other network interfaces if required.

Scroll down to “iface eth0 inet” which is under “iface lo inet loopback” and add the following information

iface eth0 inet “change dhcp to static”

address (Ip address you want for the Pi)

netmask (Subnet of your perosnal network)

gateway (Ip address of your gateway/router)

You need to inculde the titles of each section in the file and not just the numbers for this work.

So mine would look like this

iface eth0 inet static

address 192.168.1.100

netmask 255.255.255.0

gateway 192.168.1.1

Save the updated interfaces file by pushing ctrl+x and then pushing Y and then enter to return to the terminal.

Give your raspberry pi a reboot to pick up the new IP address

Raspberry pi – Setting up auto-login and auto-loading the gui

July 15, 2012 3 comments

Setting up Auto-Login

In the GUI left click in the bottom left hand corner on the blue cross to display the options menu (Like the start button in windows)

Go up to “other” and then scroll down the list until you get to “terminal” and left click

You should now see the “terminal” window which is just like a cmd box in windows and enter the following command

Sudo nano /etc/inittab

This will open up the boot time system configuration script.

Scroll down the file until you reach the line ‘1:2345:resoawn:/sbin/getty 115200 tty1’

When you see that line, put a hash # in front of it to disable that line then scroll to the end of line and hit enter.

In the blank line that appears add the following command

1:2345:respawn:/bin/login -f pi tty1 / dev/tty1 2>&1

Don’t forget to add the spaces and double check that the line enter is correct.

Press Ctrl+X to exit followed by Y to accept the changes.

To test that it works give the pi a reboot and it should now boot-up and auto-login you in ready for you to start the gui

Auto-loading the Gui

You need to start the gui with startx before carrying on with rest of this how to.

In the GUI left click in the bottom left hand corner on the blue cross to display the options menu (Like the start button in windows)

Go up to “other” and then scroll down the list until you get to “terminal” and left click

You should now see the “terminal” window which is just like a cmd box in windows and enter the following command

sudo nano /etc/profile

Scroll down to the very bottom of the file and add the following command

Startx

Press Ctrl+X to exit followed by Y to accept the changes.

To test that it works give the pi a reboot and it should now boot-up ask for a  login put in your pi account  and it will start the gui for you.

How to change number arrangements in folders in XP

July 9, 2012 Leave a comment

One of the frustrating things about folders in windows xp is that numbers are never organised or sorted correctly. So a folder contain pictures would be displayed as 1.jpg, 10.jpeg, 11.jpeg, 2.jpeg, 3.jpeg.

To change the way windows xp displays you need to do the following

1) Open Regedit

2) Navigate to the following node

HKEY_LOCAL_USER\Software\Microsoft\windows\currentversion\explorer

3) Right click anywhere in the right hand side of the panel and select “new” then “DWORD Value”

3) Name it “NoStrCmpLogical” and right click on it and select “modify”

4) In the “NoStrCmpLogical” set its value to 1 and click ok

5) Close Regedit

Hit F5 and the folder display will refresh and show the numbered files in a logical order.
