General :: Ubuntu - Removing Embedded Features From A PDF?
Jun 8, 2011
I'm looking for a way to remove embedded features from a PDF document. I recently purchased a Kindle DX. When I try to open some of my PDF files on the device, I get a message saying: this pdf cannot be opened due to embedded features not yet supported by kindleI'm looking for a way to remove the use of these features from the document so I can view it on my Kindle. I'm a Ubuntu Linux user. (I tried opening the PDF in Document Viewer and printing it to a PDF file by going to File->Print. This make it so I could open it on the Kindle DX, but the font is messed up and very difficult to read. This won't do.)
I use EasyTAG to edit the tags of my music. I believed I could also use EasyTAG to remove embedded album art, but this is not entirely the case.EasyTAG appears able to remove references to an embedded image so that the image will not appear in audio players and tag editors. However, the image must still exist within the audio file because the file size remains exactly the same. Contrast this with Mp3tag where removing album art also decreases the audio file's size.My question: is this a bug on EasyTAG's part? If so, what Linux program could I use instead?
Is if an existing option for me to disable the copy-on-write features of the MMU? I'm doing this for a project. I do not see this on the config menus (or I did not find the correct place). If it's not an existing option, do anyone know how can I change the kernel so that it can do non-copy-on-write fork?
How to connect HDMI camera to Linux? I have tried a few cameras such as the Bullet HD. I was never able to make it work in my CentOS, Fedora, I returned their product finally, it was a nightmare. Therefore instead of risking for next failure I am looking for a definitive answer on this, so that no driver issues arise under Linux and finally allow me not to use Windows or Mac anymore. Has anyone ever had success with making a very very good quality camera work in Linux, such as for example this one? Which HD cameras are there for Linux? There should be no driver issues and they should also allow me to perform pan/tilt/zoom actions using USB, Firewire or the S-Video interface.
I just installed Arch Linux, and then GNOME. But now I am regretiing the GNOME decision for one main reason; it works against the idea of K.I.S.S. and technical transperancy.But, I do like having a fully-featured GUI DE.
So, which Desktop Environment best follows the K.I.S.S. philosophy, without compromising on features? All opinions welcome, and maybe even a screenshot
Everything's working fine except for this error I get during bootup: udev: missing sysfs features; please update the kernel or disable the kernel's CONFIG_SYSFS_DEPRECATED option. udev may fail to work correctly
I don't know what to do with this. I built the kernel using the genkernel script. I'm using kernel 2.6.31-gentoo-r6 on an amd64 processor
I'm trying to install a SDK iso image onto an embedded linux platform. I was able to mount the image on the platform without problems. I also created a symbolic link called "bash" in the bin directory and had that point to busybox to satisfy the first line of code in the installer: "#!/bin/bash". However, when I run the installer, I get an error: "installer: applet not found"
I get the same error when I type "bash" on the command line. Is there a way to fix this? Here is the first few lines of code that causes the error:
Using Arch Linux. I am looking for a good word processor. I don't need a lot of file format support. Only RTF (for WordPad on W$). I want one that it is easy to use. I've been searching on Google and these are the ones that constantly show up. I have tried them, and don't like them. (Abiword was OK, but I couldn't get spell-check to work...)Just something light and easy to use, with just the usual features. I don't want a billion features. All I want is something I don't have to fight against to get a nice looking, presentable document. Emacs, Vi and *TeX* are not very easy to use, so don't mention the 'advanced' ones like that.
I am using embedded linux (xlinux) and i need to compile the programs on desktop pc.i am currently using eclipse.can someone suggest me how I can configure, to make a project thats compile the programs for the embedded linix where I need to run them.
I need to use xdelta tool in my shell script for creating and patching diff files. My PC Linux environment (Ubuntu) has a package installer, and when I try typing xdelta on my commandline, it prompted to try "sudo apt-get install".. after which it directly accessed the packages from the Internet and installed it. So I am able to use xdelta from the command-line in my Ubuntu environment.
I need to also use xdelta on my target. I am using a NFS. The bootloader and kernel are on the target and the RFS is referred from the PC. How can I install the xdelta package on my target so that it recognises the command xdelta. On Ubuntu, "sudo apt-get install", fetched the below packages:[URL]..
I am developing a device that will run Linux as its operating system.The device is a small form factor X86 device with a flash drive exposed as a SATA-device. So it is not very dissimilar from any other PC running Linux.For several good reasons I am building my own "distribution", instead of using an existing one.What confuses me is how mount/umount of the root file system is handled.I boot my kernel with the commandline "root=/dev/sda1 rw" which works fine. But everytime I do poweroff or reboot Busybox complained about no /etc/fstab, so I decided to build one.Should I have an entry for my root file system? It seems like this is shadowed by the rootfs anyway. I.e. if I have the fstab entry "/dev/sda1 / ext2 1 1" mount still reports rootfs on / type rootfs (rw)/dev/root on / type ext2 (rw,relatime,errors=continue)My questions are:Do I need to worry? Will the drive be correctly unmounted by the kernel on poweroff/reboot?If I want to perform file system checking on boot, can I do that without resorting to an initrd?
I currently work within an RTOS environment without an MMU and thus have access to the entire memory map of whatever application I'm working on. As is common in the embedded world, different parts of the memory map relate to different peripherals or different types of memory. For our next generation hardware, my company is looking at moving to an MMU-enabled processor and using Linux in some shape or form. Most of us in the dept are familiar with Linux, but we are not Linux gurus by any means. So how to explicitly indicate to Linux that we need certain portions of an application to be stored in NVRam and other portions of the application to NOT be based in NVRam has us confused. None of us have a clear understanding of how user memory is delved out by Linux and how we can influence Linux to use specific portions of the memory map at specific times.
For example in this new application, we expect to have 2 memory chips, both that are DDR3 interfaces. One is a standard DDR3 chip. The other is a non-volatile MRAM with a DDR3 interface so it can be accessed by a DDR3 controller and coexist with conventional DDR3 memory. But because the portion of the memory map that the MRAM will represent will be the only portion of non-volatile memory, we are unclear how we explicitly access MRAM addresses in an MMU-controlled environment. My hail-mary guess was that we would want to somehow tell Linux that we want the MRAM's memory space to be mounted as a RAM Drive and then we access that memory as though it is a file on a HD, except it is much higher speed since it will be at DDR3/MRAM speeds. Is there a better, more straight forward way to do this? Coming from an RTOS world, Linux is going to pose some serious challenges for us, but I think it will be the right move once we are all up to speed and are thinking Linux-centric.
We have designed a board with Cirrus Logic(arm) processor, A Flash memory and some other peripherals have been connected to that. While building kernel we have selected MMU support. We have written few custom drivers for keypad,LED,LCD. But I would like to know how virtual memory mechanism can be helpful here even though there is no any hard disk has been connected. Where will be the virtual memory reside.
what i did was, remove evolution mail from synaptic, what i wanted to do was just remove the indicator applet from the task bar. i read a bunch of bad stuff about removing evolution from synaptic vs just removing the applet.
im worried. did i break anything or put my security at risk. after, i used a command (older) (sudo apt-get install ubuntu-desktop)to install ubuntu desktop. because i thought that it would fix evolution. then i went to synaptic and installed a package called evolution. i rechecked evolution in applications menu. however, i notice that i have both a checkable evolution and two evolution icons. nothing 'seems' broken. im not sure if it ever was. and evolution calender pops up as normal, as does the the installed plain evolution. they both seems to be an exact copy of the other.
all i really wanted to do was remove the indicator applet. did i make a serious mistake. since ive had ubuntu, ive reformatted a lot because i was worried i made a mistake of some kind. however now im into the more "make a mistake and fix it stage' as im pretty happy with my current desktop and have worked hard to customize it. the command, sudo apt-get remove indicator-messages removed the mail icon. i still am worried that i broke something, or put my security at risk. also, now i have two mail icons. evolution mail and calendar, and another just called evolution.
I am looking for tools for static/dynamic code analysis for embedded Linux system development (both device driver and user space apps). We will use Eclipse IDE and C++ lanuage. I hope the tools are easy-to-use, reliable, popular, better with good supports, and not-too-expensive. I already find a list of tools at WiKi, however, I don't have time to try them all. Could anyboy please recommend me a few? If you can tell me briefly about their pros and cons, that will be the bet.
I'm trying to solve an intermittant serial port problem on an embedded medical monitor. We have determined that the port is receiving characters from the external device but the serial thread is not transferring the chars from the buffer. Has anyone seen this before? Looking for some guidance on what to look for. this problem happens at start up about 1 in 50 boots. We're using kernal 2.6.29.6.
I am looking for tools for static/dynamic code analysis for embedded Linux system development (both device driver and user space apps) with ARM-based processor. We use Eclipse IDE and C++ lanuage for development. Does anybody have recommendation for tools to analyze code complexity? The tools is better to support McCabe complexity metric, however, we may also consider others. Does anybody have recommendation for unit testing?
I'm trying to run a shell script on a kern board (av1100) that shows some text output on the attached screen. The big problem is that the screen goes to blank in like 2 minutes.I'd just like to have the script showing it's output while the thing is on.Isn't there a command to stop the screen from going to blank?p.s. there is no bash available, just #!/bin/sh
I'm working on a project to have our company logo image display on the screen during bootup. Our platform is an embedded Linux device running on a custom configured linux kernel 2.6.38.2. Our development distro is Ubuntu 10.04. I am currently trying to get fbsplash to work on our device with no luck so far.
I know a bunch of commands and I am comfortable using the terminal, I even set a powerpc server but I can't figure out how to remove epiphany on this new computer I'm setting up. I didn't install anything with tasksel. I installed gnome and xorg afterwards... I load it up and 'startx' just fine. then I check around for the programs that were installed. I lik'em gimp, lot's of utilities. gedit. anyway I find epiphany, which I have already established that I dislike, I immediately go to the root terminal (another nice program that comes with gnome) and type apt-get remove epiphany-browser-data the output says it will be deleting gnome... however I have researched and found these are simpy meta packages that don't really matter.... however under the section that states all the packages that will be removed by autoremove there is a huge list... I doubt these packages are safe to remove. how to remove epiphany without removing a huge amount of probably needed software
These should be my last pleas for help with regard to Fedora 13. I've been unable to turn off the notifications that appear in the top right corner, despite a decent amount of searching on google. I can't remove any notifications package without removing a bunch of important software along with it. Also, F13 refuses to "Safely Remove" either of my external disks. I have to yank out the usb cord, touching wood each time.
I'm developing an embedded Linux (it is almost over now). What I'm struggling with is the system goes unstable by cutting power source frequently and it does not boot anymore. It even does not perform fsck. The system just has a XFCE with a fixed Qt App autoloaded to display some charts. My question is that how commercial embedded Linux distros (like Wifi AP's management Linux, ...) avoid this problem?
I've developed a tiny webserver for home automation out of an ALIX 1D, and based on a debian lenny. It runs very smoothly and is now able to operate quite a lot of different equipment from a webapp. But i'm not sure how I should handle the compact flash, regarding read/write limitations. From what I've read the partitioning should be ext2, which would disallow the journalisation of the system. A utility to 'flatten' the repartition of write cycles exists, would it be relevant to use if the partition is ext2 ?
I will also disable all logging in execution mode (a debug mode will provide the logs). Is there any other parameters I have to take into account for maximum reliability (i.e. does the system randomly write in some files for various and potentially turned off purposes)? As for the mysql database, it's not important data, and it's actually reconstructed every time the server boots. Given this, is there a way to store the db in RAM rather than in a file? I'm not sure it's the right place to ask, but I sometimes see redirection to here from stack overflow.
Is there a terminal emulator which works well in an Ubuntu desktop and provides the following features which Mac OS X's Terminal application has? Re-wrapping text when the window is resized.A Clear command which clears scrollback (as the shell clear does not) and does not clear the cursor's line (typically containing a prompt).
