Ubuntu :: Looking For Electrical CAD Not Electronics?
Oct 22, 2010
Can anyone point me in the right direction ?
I'm looking for electrical cad software similar to AutoCAD Electrical or PCSchematic Automation. I need something to do WIRING diagrams as apposed to circuit schematics like Egal. Electrical not Electronic. I'm talking about power distribution, fuses, relays, PLCs, motors, solenoids, switches, buttons, and cables. I am not talking about transistors, capacitors, integrated circuits, and printed circuit boards. Sorry to put such a fine point on it, but there are a lot of PC board design tools out there that use the word "electrical" in their description, but are not useful for diagramming the wiring connections in a machine.
I think an electrical cad program should have the following features in order of importance code...
Here is an example of the sort of thing, but wiring diagrams can represent an entire factory, documents with hundreds of pages.

I have an Encore Electronics 802.11g Wireless LAN Adapter installed on a secondary desktop. When I was running Windows XP the wireless signal was strong and did not disconnect. When I installed Ubuntu the wireless signal is weak and it will not stay connected. Would there be a driver for Ubuntu to work better?

I'm trying to get my resolution to match the resolution I use in Windows 7 which is 1768 x 992 (50hz) Nvidia Geforce 210, LG Electronics 37LF75 - At the moment the top and bottom are both missing off the screen. Everytime I try to adjust my xorg.conf file it hangs at boot. Not really sure what exactly I'm doing with it.

I am building a home server that will host a multitude of files; from mp3s to ebooks to FEA software and files. I don't know if RAID is the right thing for me. This server will have all the files that I have accumulated over the years and if the drive fails than I will be S.O.L. I have seen discussions where someone has RAID 1 setup but they don't have their drives internally (to the case), they bought 2 separate external hard drives with eSata to minimize an electrical failure to the drives. (I guess this is a good idea)I have also read about having one drive then using a second to rsync data every week. I planned on purchasing 2 enterprise hard drives of 500 MB to 1 GB but I don't have any experience with how I should handle my data

I'm looking for Linux software capable of producing Electrical diagrams. The Windows standard, is of course, AutoCAD (Electrical), and I'm wondering if such a program exists for Linux, specifically the Debian branches (I'm using Mint).I'm in the Fire Alarm industry, so the candidate I'm after will have a library of symbols pertinent to Fire Alarm system design.

I have heard this is part of Fedora. I installed everything with ver 12, yet I do not see it anywhere. How to I access it, or aquire it, if I was misinformed. alternatively I was trying to build kicad cause I could not find an RPM for it. It reported that it needed wxwidgets which I was unable to install successfully. I do not know a whole lot about linux, but I am having problems with a circuit I am designing and tired of bread boarding everything. A fully functional schematic editor and analyzer at the low price of free is all I can afford right now.

I'm new to Linux, so I decided to try using Wubi to get started. THe problem is, when it finished installing 10.04, I got this message: OSError: [Errno 13] Permission denied: u'C:\ubuntu\install\ubuntu-10.04-desktop-amd64.iso' Is there any way around this? It might just be that overly restrictive thing called Vista (which I have the bad luck to be using). I was considering getting a USB drive for Ubuntu anyway..

What is the difference between the Ubuntu Installer for windows and the Ubuntu CD image? If I use the ubuntu installer for windows, does it have the capability to partition my drive, will it enable to share files with windows etc or is it just a way not to have to burn a CD. Just curious, the exact details of the installation files were not made clear on the website. Note: Windows Version: XP, 32bit, SP3. I have not partitioned anything yet.

I have windows 7 installed on Disk2 (according to windows Disk Manager), and I installed ubuntu 10.10 on Disk0, choosing the dual boot option at installation.
However, grub does not load (presumably because its on disk0 and my machine appears to boot from disk3), so the machine goes straight into windows 7.
How do I get ubuntu to load?

I'm currently running off of my live-cd, and after spending 4 hours of my life trying to fix this myself, i figured someone out here has to know how to help me. Basically, i wanted to try linux, then liked it enough to decide to put on one of my usb-drives (320g adata nobility NH92), and i couldn't get it to boot anything but windows w/o the live-cd, which would then boot the live-cd, lol, in other words, i couldn't get it to boot at all from the external, even though i had changed the setting in my bios to boot from usb first, and tried manually selecting boot from usb and all that fun stuff.
Sooo... eventually i decided it might be a problem with the bootloader, and while i'm not exactly sure at this point what i have done to my computer, all i can successfully boot is the live cd. When I try to boot w/o the live cd, whether i try to boot from my internal (windows) drive, or external, all i get is a device not found error.I think i could fix it if i had windows recovery cd's (i'm running xp, btw), or installation cds, but... unfortunately, they died in a terrible accident. So i have no cd's at all for windows. :/

I have been running Ubuntu 10.04 under Windows 7 (Is this call WUBI?) without any problems for a while. My other machines only run Ubuntu (9.04 & 10.04). I decided to give it a try to the latest Ubuntu 10.10. After going through the successful installation and then rebooting, I am getting the following error message once I select 'Ubuntu' in the boot up menu right after the BIOS screen: Booting ' Ubuntu 10.10, kernel 2.6.35-25-generic'

I'm wondering if this is even possible. I've searched high and low and have yet to find and answer to this particular setup.
The setup:
Router is in another building.
Desktop connected by WiFi
Laptop connected by WiFi
Both the Desktop and the Laptop are in the same building together. About 5' apart.
SSH server is setup on Desktop
FreeNX client is setup on Laptop
So they can connect just fine via WiFi for remote desktop control of the Desktop from the Laptop (so SSH and FreeNX are working).Is it possible to connect the 2 pc's directly to each other by Ethernet cable AND transfer files between them by Ethernet while still being connected to the Internet by WiFi on them both?Or would the WiFi have to be disabled while using the Ethernet connection?Neither has a Gigabit Ethernet NIC so I know it would at least require a crossover cable or another router to connect the 2 by Ethernet cable.The idea behind all this is to be able to transfer files between computers quickly by Ethernet while the computers are still busy doing other things on the Internet by WiFi.

1. I accidentally wrecked a previous Ubuntu installation so I decided to re-install via the Ubuntu disk. Unfortunately Ubuntu doesn't let me override previous Ubuntu installations...
2. Ubuntu Maverick Meerkat is due to released in about 3 weeks. I want to install it via a clean install.
3. So can anyone tell me how to remove both Ubuntu partitions safely. I am currently running WinVista with Ubuntu Lucid Lynx. I know I have to use something like this to erase GRUB2. Can anyone give me a good tutorial?

The scenario is as follows - I will be moving across the country and my desktop will stay here powered and online, while I move with a laptop. I need a way to connect to the desktop for file streaming(music and movies) as well as using the virtual machines. I have thought about SSH and VNC.I need something failsafe. That's priority one. I won't be around to fix it if it breaks. I can set the computer to come on in the BIOS at a certain time if the power went out. But if I can get in remotely the whole setup is useless.SSH only provides terminal use, correct? So if I chose that route I would be able to access the computer via command line and play music and movies with mplayer and such, correct? But I would not be able to run the virtual machines? Because there will be no GUI, right?
I have been playing with Vinagre and Vino through the host and guest of a virtual machine and I cannot get it to connect. Is there a better application? x11vnc? I have forwarded port 5900 on the router and have upnp enabled. Got a better remote desktop suggestion?I would like to run this setup headless.(no monitor) I also would like to run it without a gpu if that is possible to make it more energy efficient.Both computers are 64 bits and will be running Ubuntu 10.10 and soon 11.04.Are these crappy ideas to begin with? Should I go another route to get my files and access the virtual machines?

After a reinstall of 10.10, I am able to turn on file sharing and so I set up a shared folder.
Windows Vista can see this folder but in my network place, there is only one icon, and it's a "Windows Network" icon. Upon clicking on that, I can see the local network, "Rompus Room".
When I click on Rompus Room, nothing happens for a while, then I get a message saying, "Opening "ROMPUS ROOM". Then I get the final message, "Unable to mount location", followed by, "Failed to retieve share list from server"

I was running 9.10 in LiveCD mode and was unable to get online. Went to System>Administration>Hardware Drives and found "Broadcom STA wireless driver". Cool. So I went ahead and installed 9.10 (dual boot with Vista), repeated above steps but found no "Broadcom STA wireless driver" option, in fact no proprietary drivers. So I still cannot connect to the Internet, and I don't know where to go from here. (Note: I installed 9.10 side by side with Vista: good? bad?)

I'm about to install Ubuntu on two 250-gigabyte hard drives in a RAID 1 array, but I'm confused about how to partition my hard drives. How much space should I give to each partition? How many partitions should I create and where should I mount them? (I should mention that Ubuntu will be the only OS on this array.)

I am trying to install Ubuntu server edition on an old HP XT963 that recently came into my possession. I mainly just wanted to use it as a home file server and print server. I have been running ubuntu desktop on my laptop for a little under a year, but this is my first go at the server edition.
While ubuntu was installing it said "network autoconfiguration failed," I hit continue, thinking I could figure out how to configure it later. After lots of googling I still haven't figured out what exactly is wrong.
Code:
auto lo
iface lo inet loopack
after googling around I made it look like:
[Code]...
I would like to provide more information such as ifconfig and any other commands but I'm not exactly sure how I would do that without being able to copy/paste. I guess I would have the command dump the output to a file, but I'm not familiar with the -options this being my first time CLI-only.
