Linux Driven Information Display?

This is kind of a linux question.

I have no window at work. I was thinking of taking a small LCD and hooking it to a Raspberry Pi (Or some other tiny board PC) and then linking that to my cell phone to stream a webcam from Grand Turk, or wherever I want to see that day. My phone is 4G and I have 30gigs of data a month. My question is, how much bandwidth does VIEWING a webcam take? I think most of them update every 30 seconds or so.

On a related note, does anyone have experience with LCD4Linux? Is it possible to use that to display a webfeed?

Thank you

Hi,
I am using 2 screens (my current laptop screen and extended to my TV using HDMI), I am only using one x-server (ctl-alt-F7) on ZorinOS 9.1

on the terminal, DISPLAY using: env|grep DISPLAY variable always shows :0.0 for both screens

I thought it would show :0.0 for my laptop display and :0.1 for my TV, its showed :0.0 on TV as well, could some one tell me why.....

Hi all,

Very basic question I'm afraid! I installed Linux (with difficulty) as it turned out that I had a duff copy of Windows on my 2nd hand laptop! I'm not as computer-literate as I used to be in the days of DOS and early Windows, nor am I as patient - it all seems to be so complicated now!

I cannot find out how to open a window that's minimised to the task bar. In windows it would just be a click, which as so much of the user interface is similar I'm mystified! It'll turn out to be something incredibly simple, please!

I can do it the long way with alt+tab and scroll through but surely there's a faster way?

How do applets in the panel on the right also get opened as alt tab doesn't work on them!

Any guidance would be SO much appreciated as I've faffed with this for weeks!!

Thank you.

Hi I am not a complete Linux newbie, but I have a challenge that is new to me.

I am wanting to be able to connect to a linux box (Raspberry Pi running Debian) via ssh directly from a single computer. I want to be able to plug in a ethernet cable from a laptop to the Raspberry Pi so that I can configure it via ssh or a webpage.

I have had a few pieces of hardware, routers, printers etc that allow this sort of connection for configuration, I just would like to know how it is done.

My question is how do I set up the /etc/interfaces file to allow the Raspberry Pi to be found by the laptop.

Once configured I would want the Raspberry Pi to obtain its IP address via DHCP when connected to a network.

Any suggestions, ideas would be appreciated.

I know the command many display current month and year .

Code:

#date +%b%Y

Jun2015

If I want to show the last month and year ( as current month is Jun2015, I would like display May2015 , if current is Jan2016 , then display Dec2015 ) , would advise what can I do ? thanks

Hello, I'm having a problem on Kali Linux. I've added some shotcuts to the top panel but it shifts to the left from time to time until I cannot see anything I cant even click on Applications menu because it clicks the shortcut behind it.

Example:

It fixes when I log out and log in again. I'm looking for a permanent solution, any help?

Thanks.

Hi,

I am hoping someone can help me.
When attempting to look at CPU\mem usage etc by using the 'top' command I find that it just doesn't display properly. For example:

I have been able to use it before in UNIX so I know that the layout should not look like this. I'm not sure where the Bs are coming from!
Is there something I need to install or modify to get it to display in the correct format?

The OS information is as follows:

Red Hat Enterprise Linux Server release 6.4 (Santiago)
Kernel 2.6.32-358.14.1.el6.x86_64 on an x86_64

Please let me know if more information is required.

Many thanks in anticipation,

Hello, I am new to Linux and I am having difficulty setting up KDE. I have a vps with Debian 7 Wheezy on it and I need to get KDE working on it. The Linux installation from the vps company was very basic...I had to update the packages and install kde and kdm using the apt-get install kde and apt-get install kdm commands. When I type xstart to start the x server I get a message with the version number and other information so I am assuming that it is installed, but at the bottom of the message I have no cursor (I am able to type but when I hit the enter key after entering a command nothing happens) and the # is no longer there so I am unable to continue working. The only way i can get the command prompt and # back is to close Putty and reopen it (then I have to log into the vps all over again). From what I have read online, when I type startx, it should load KDE.

I was able to set the display by using the export DISPLAY=:0.0 command. But when I type startkde I get the message 'No protocol specified" and the next line says DISPLAY not set or unable to connect to xserver.

I have been using Putty to log into the vps, but yesterday I decided to use the web based login utility offered by the vps company. When connecting to the vps in this manner I am presented with a traditional looking login screen (I am assuming it is KDM). The user name that was provided to me from the vps company is 'root' ...well, when I try to login using KDM (the plasma setting) I get an error stating that 'root' logins are not allowed. Considering that the KDM is visible when logging in using the web based utility, I have a feeling that the KDE is also working...but I can't log into it because the user name is 'root' . However, when I use Putty I cant seem to get anything to load and start the way it is supposed to. I would appreciate any help in getting the KDE to work in Putty and the login via the web based utility to accept my username that the vps company gave me. Thank you.

The Centrino laptop I have as my server seems like overkill so I am looking at some alternatives. At first I was going to use a Raspberry Pi but someone on these forums pointed out there are better solutions. This lead me to the pcDuino 3 Nano and the Odroid-C1

First, my server will handle a printer, a file repository, simple backups of the most vital files (Pictures, documents, etc), and coordinate my webcam surveillance feeds (I think zoneminder?) . The problem is I am a PC guy and have little more than basic information about linux or ARM architecture. The only ARM device I own, aside from cell phones, is a Pogoplug that I have managed to kill by trying to put linux on it.

I am cruising Google trying to glean as much information as I can but the level of ignorance on my part is staggering. This leads me to you wonderful people.

To make things easier, the specs:

pcDuino 3 Nano
1 gig of RAM
1GHz Cortex A7 Duel Core CPU
4GB flash memory + micro SD card slot
3 USB ports and 1 SATA, among others

Odroid-C1
1 gig of RAM
1.5Ghz Cortex A5 quad core CPU
micro SD card slot
4 USB ports among others

From my untrained eye, I think the pcDuino is the better choice due to the SATA port but the Odroid does have a quad core CPU. Will linux take advantage of those extra cores? Also, since these are ARM CPUs I understand they won’t run normal linux distributions. Will I have problems with SAMBA, CUPS and RSYNC? My research says no but I’d like to confirm before I spend the money.

As always thank you in advance.

I have downloaded an attachment from a website and an icon has now appeared on the bottom panel of my debian distro with gnome shell (classic).
This icon will not go away even with reboot.
If I right-click on the icon it offers me 'launch' and 'properties' option. But there is no 'delete' option.

If I click on the icon it will take me back to the same website and open the attachment again.
Now it's forever on the bottom panel of my desktop.
Clearly this is a bug.
Can someone please advise how I can get rid of this? Thank you in advance.
