Basically the computer will have to do nothing other than run some custom software that interfaces with the vehicle's systems via a USB FDTI board and render to an 8" touch screen via OpenGL. User input will be via the said touchscreen, and audio output will eventually come into the equation. The target vehicle(s) will be extensively modified for the project, and I'm hoping the software will eventually override features such as the immobiliser, so an extremely fast boot time will be essential.
I have one of those Via C7 fully integrated mini ITX motherboards, much of the onboard hardware will be useless besides two USB ports and a SATA port, so could be completely removed from the kernel if necessary to achieve a fast boot. If some BIOS hacking is required I'd happily look at that too. I'm a recently graduated software engineer, and can comfortably use Linux (I'm using openSUSE for developing the software) but don't have a clue where to start with the OS; if I should be downloading and modifying an existing distro or trying to build one from scratch somehow?
I'm having difficulty setting custom ls colors in xterm. If I understand it right one can edit the system-wide file located in /etc/DIR_COLORS to modify every terminal or customize xterm; I chose xterm mostly because the other terminals I never use. Here is my .bash_profile and .bashrc respectively: if [ -f ~/.bashrc ]; then source ~/.bashrc fi
if [ -f /etc/bashrc ]; then source /etc/bashrc fi
alias ls='ls --color -F' PS1='[e[1;32m][u@h:w]$[e[0m] '
When I use the login shell, the colors are different than xterm in that they are not as bright; furthermore, I marked out bold fonts in .Xresources: !xterm colors xterm*foreground: #d3d3d3 xterm*background: #000000 xterm*boldColors: false xterm*cursorBlink: true xterm*cursorColor: white xterm*loginShell: false xterm*faceName: Liberation Mono xterm*faceSize: 10
So, there must be a file around somewhere that is changing the colors between the interactive and login shells. Also, man xterm: color6 (class Color6) color7 (class Color7)
These specify the colors for the ISO-6429 extension. The defaults are, respectively, black, red3, green3, yellow3, a customizable dark blue, magenta3, cyan3 and gray90. The default shades of color are chosen to allow the colors 8-15 to be used as brighter versions. How does that get anyone anywhere with setting the color? It doesn't say what color (class) is assigned to which file specifically, thus adhering to the distribution-wide color codes. Perhaps I am making this more difficult than it should be.
I have a custom PS1 that I would like to use for my user account however when I view my users .bashrc file, there is no line entry there for 'PS1='. Can someone please tell me if I have my own custom user PS1 line entry, where do I place it so I can have some extra function and colors in my RHEL 5 system.
I have ubuntu 10.10 installed on my computer in dual boot with windows 7, but i am using a 27-inches Samsung screen through an hdmi cable to connect my computer. whenever i try getting on ubuntu, i cannot see the top and bottom of the desktop (so i cant access the menu bar or anything!)(while using my spare vga cable) i tried downloading the nvidia driver & utility for my video card (gtx 460), but even using that, i could not setup my screen resolution manually. When i setup my windows, i was able to manually setup a custom resolution (i.e. 1842x1026) through the nvidia utility to be able to get the screen the fit properly.
I was wondering if there is any way i could do the same for ubuntu, perhaps through terminal.
I'm trying to set the default apps using gnome-default-applications-properties. In previous versions I was able to set custom apps for everything. Looks like Gnome3/Ubuntu 11.04 doesn't let me do that for, say, the mail reader. I'm one of those people who still use Alpine, and in previous versions I was able to set the default to run an xterm (well, aterm) which auto-ran alpine.
This version, looks like that's not there. I'm wondering if there's a way to set that anyway. like registering a script I write as a "mail client" so it's available in the chooser. Second... and almost MORE annoying... the "Terminal Emulator" default app DOES have a custom option. But it also recognises that I have aterm installed, which I want to use as the default app... however, since it has an aterm option, it won't let me enter aterm as a default command. Which I want to do because I want to modify the commandline options. But if you choose "Custom" and type "aterm" into the Command field... it ERASES your commandline options and puts it's default sterm options in!
I am using the elementary gtk theme, but I wanted to have my gnome-panel have a set custom background, so I went into the 'gtkrc' and commented out "#include "Apps/panel.rc"". This worked perfectly but, the right click menus and drop down menus changed color which conflict with the icons that I am using.
I installed Fedora 11 on a server with 2 equal sized disks. I used the gui installer and didn't make custom setting changes to the partitions. One of the steps asked for me to choose the disks i wanted to use for this installation. I selected both disks and after the installation Fedora only sees one volume the size of both disks combined.Do I now have software raid0 or do I have something else?
I dont know were to begin to solve my problem and I have been googling for hours to get a hint without any success. I'm runnning a Counterstrike Server on my virtual openSuse server - I'm exploring so don't justify what I am hosting at the moment
I want to make it possible to gain access to the cstrike folde via a ftp login. But I really have no idea were to start. The server is also a webserver, where I can ass FTP accounts for my apache vhosts via plesk - but I dont think this is the solution of my problem, isn't it?
Whenever I login or restart the computer, my resolution gets reset. I think it may have to do with my setup being connected to a 18.5" HDTV. Is there a way to set custom resolutions in the OS, so that Nvidia and OpenSUSE can recognize them?
03:00.0 VGA compatible controller [0300]: nVidia Corporation ION LE VGA [10de:087e] (rev b1) Subsystem: Acer Incorporated [ALI] Device [1025:0222] Kernel driver in use: nvidia
Just spent three whole days barking up the wrong tree, solving Fedora 11 and Fedora 12 boot failures because the correct hypothesis was illogical: installation did not update/modify the initrd.
The first couple of times I installed Fedora 11 on the HighPoint Technologies RocketRaid 2640x4, the installation inserted my "custom" driver module (rr26xx) into the initrd, permanently, so that the system booted off the controller card for which the custom driver was inserted. (I yelled about this success in this thread: [url]
My most recent installs of BOTH F11 and F12 on the RocketRaid failed to properly set up the boot. It turns out that the "rr2640" module I "slipstreamed" into the installation process was *NOT* permanently added to the initrd by anaconda. (F12 gave me "no root device found boot has failed, sleeping forever", on boot; F11 hung also, without such error, I presume, during the init script execution). Because of limited resources and time, I only know for sure the module was missing from the F11 initrd, and am ASSUMING the same was the case with F12.
The only difference between the successful installs and the ones with failed boot is that the successful installs were made on a single-drive (JBOD) mode on the controller; whereas, the failed ones were placed on RAID 5. But, AFAIK, the created logical device for the card is "/dev/sda", in both cases, and the kernel can not distinguish between the two cases (or can it?). Thus, the inconsistency cost me a lot of time, and is still inexplicable to me.
Question: What is the best way to deal with custom drivers, today? There are custom spins, and many tools, like isomaster. Stupid question: Is there a way to modify the initrd inside an installer ISO -- be it for CD/DVD/USBboot drive -- beefing the init RAM disk with whatever modules you'd like, for the boot process (using, say, isomaster)?
And what makes anaconda understand that a module must be added to the initrd ? How can one force anaconda to do so?
How does moving to dracut as the initrd tool affect any/all of the above?
I have a ubuntu server , can advise if I want to change the network setting ( eg. IP address , gateway address etc ) , which one is the configuration file ? for example , if I want to change eth0 setting , what file I should update ?
I've been struggling this morning trying to associate an application with a custom protocol, namely emacsclient and org-protocol.
I'm calling this protocol from a webbrowser bookmarklet, and I get the following behaviour :
In chromium, the "Launch Application" dialog comes up, and calls xdg-open org-protocol://... which ends up firing a new chromium frame.
In firefox, I've tried setting network.protocol-handler.app.org-protocol to an empty string or my emacsclient path, anyhow I get the following error message : "Firefox doesn't know how to open this address, because the protocol (org-protocol) isn't associated with any program" without even showing any external application selection dialog.
I'm not using any desktop environment, so I need to make this work strictly with xdg, however, despite reading the shared mime info spec etc, I still can't fathom a working configuration.
So I'm here thinking how to create custom commands on my Linux Debian? I mean so i could open up terminal and just type the script name (and possibly some arguments) and it would refer to the script in my home directory. Otherwise I've write the whole path to the script each time and it gets annoying.
Had a custom kernel (2.6.35.5) running under Slackware 12.1 and also the same kernel on an Ubuntu 10.04 machine just fine, however after a clean install of Slackware 13.1 this kernel no longer works (This kernel was re-compiled with the same .config file under Slack 13.1) as I keep getting the the following: -Please append a correct "root=" boot option Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(8,3) The strange thing is it keeps looking for the root file system in hda1, however the stock 13.1 kernel finds it in /dev/sda1 so the root partition is /dev/sda1 in lilo and the harddisk is known as /dev/sda.
I found that Linux Ubuntu has custom keyboard commands.his is awesome.What I'm trying to do, is make a command that will shut down the computer with a single button with no dialog windows.For you know, being grounded nd stuff.I found the command for it is "shutdown" with a few options.But when I tested it, being bound to pause/break, it did nothingAm I writing the wrong code, as I'm not using any options, or is this not possible?
I don't really like Los Angeles (they steal all our water) and neither Tijuana nor Vancouver make sense to me, so I am trying to make my own, custom timezone of Felton, California. How do I do this? I changed my /etc/timezone to "America/Felton" but upon reboot my calendar still says "Los Angeles". Which files do I need to change?
I am currently running a old school hacked Linksys WRT54G and have played around with some of the hacks and currently running Tomato on it and I am pretty happy (tho the lack of OpenVPN Server suck) but I need an upgrade to something with 802.11N and I bet I am not the only one. The options right now are
Grab a hackable consumer 802.11 Dual Band-N router and throw on it DD-WRT, OpenWRT or Tomato again Build my own using old hardware (dont really want to, feel they eat too much power for a simple task) Build/Buy hardware for a custom router (Atom system, or I recall back in the day some people use to sell small ATX-like boards just for embedded linux to run as a router) So what option would you go with and why? And if the DIY route should I try to get some hardware that is pre made for the job or DYI like a Atom machine.
I am doing this as a test for bigger deployment. I have Apache running on CentOS5 in a clean VM (just a few tools installed, PHP and such).If mod_ssl is set to listen on 443 in /etc/httpd/conf.d/ssl.conf the the site at https://192.168.1.137 loads just fine.If I change the listen port to eg. 9443 in ssl.conf and reload httpd the page wont load athttps://192.168.1.137:9443 - I set the eth0 to be trusted and disabled SElinux in case that was interfering but still no luck.
How would someone with very little programming experience go about creating a custom virtual musical instrument? Each key would produce a tone of a specified frequency when clicked. Instead of being limited to a piano keyboard layout, each key would be movable. Holding the Shift key would allow multiple keys to sound at once. (See attachment for what it might look like.)I know there are dozens of possibilities (Flash, Java, etc.) Which would be best?
Under Debian "Expert Installation" once I have chosen installation/system language and location, I get an informative notice, that:
Code: There is no locale defined for the combination of language and country you have selected.
..and I need to choose one locale available for the selected language. As I understand, locale is just a set of environmental variables used by applications and printed out with locale command?
In addition, is it possible to generate own locale files after the installation, which will match my needs?
I am looking to assign custom icons to my folders. Like the game folder having a joystick , Ebooks folder etc. but sadly i am unable to find any thing on google. Can any ome suggest some good places to look
I have a custom command I've made to quickly shut down all of my xen instances.
Code:
[root@LCENT02 ~]# virtdown -bash: syntax error near unexpected token `2'
As you can see it fails when I try to run it on the command line. It is stored in an ~/.env file in my home directory. What is odd to me is if I open the .env file and copy the command from there and paste it into the command line, it does actually work!
Code:
[root@LCENT02 ~]# for i in `virsh list | grep -v -e Id -e --- -e Domain-0 | awk '{print $1}'`; do virsh shutdown $i; done Domain 1 is being shutdown Domain 2 is being shutdown Domain 3 is being shutdown
And this is how I have the command entered into my .env file:
Code:
alias virtdown="for i in `virsh list | grep -v -e Id -e --- -e Domain-0 | awk '{print $1}'`; do virsh shutdown $i; done
Why would this command work if you paste it onto the command line but not use the custom command virtdown?
