• Running UBUNTU from a USB Flash drive on Acer

  - by Byron Blue

  I've made a bootable USB flash drive to run UBUNTU. The drive works fine on MOST laptops/computers I try: It does not want to start on my (favourite) Acer Aspire 5745 (Windows 7 64 bit). The opening screen has SYSLINUX 4.06 EDD 4.06-pre1 (...) and simply sits there. I was using UBUNTU 12.04.1 64 bit until I tried booting to the Acer this morning. I've tried booting to 10.04 as well (saw this as a fix on a discussion) with the same result. I really want to use the Acer for development and do not want to wipe my Windows 7 from the hard disk. Are there any solutions/answers?

• Codec Problems with trying to edit videos with VirtualDub

  - by Roy Rico

  So, I'm a little frustrated. According to this post and various other internet sources, virtualdub is supposed to allow users to quickly split and join video files. I am using windows 7 64 Bit and the latest version of VirtualDub (64-bit). I have tried to edit various movie files, and each attempt at editing various files I have done has not worked for me. AVI file A.avi won't load, saying that it can't located the Decompressor for the "FMP4" format. I have tried this solution and this one, and neither of them work. I have tried setting the VFW Decompressor for 'Other MPEG4' setting to XVID or LIBAVCODEC. There is no change in virtual dub AVI file C.avi will load in Virtual Dub, but any attempt to split it gives me an error that I don't have XVID codecs installed. I've attempted to install the proper codecs (Shark's Windows 7 Codecs, CCCP) with no change. AVI file C.avi will load, and it will split, but won't split using the "Direct Stream Copy" claiming the compression algorithm is incompatible. I tried "Fast Recompress" option and it created a 27GB file out of what was supposed to be about a 300-400MB file. Can someone please give me some insight into what I'm messing up?

• Can't use laptop display?

  - by Ian Rice

  I've just installed Ubuntu 11.10 with a LiveCD. During the installation, nothing was shown on screen unless I plugged in an external monitor. Same thing happens within Ubuntu. I have an Emachines E525. Could this just be a backlight issue or something? It works fine on Windows though. If anyone could help, that'd be great. Please explain everything throughly if you can though, I'm new to all of this.

• Handbrake-powered VidCoder gets a native 64-bit version

  A while back, VidCoder -- the Windows video disc ripping program -- added support for Blu-ray discs. With Handbrake's engine under the hood, VidCoder offers an easy-to-use interface and simple batch processing of your video files. With the release of version 0.8, there's also now a native 64-bit version for those of you running Windows x64. A number of stability tweaks have also been introduced. As Baz pointed out in our comments last time, VidCoder is particular useful on netbooks. If you've got a 1024x600 screen, Handbrake may not even launch for you -- but VidCoder will fire up just fine. Take the new 64-bit version for a spin, and share your thoughts in the comments.

• How can I put Fedora GUI onto Ubuntu?

  - by Dareleth

  Okay, I'm pretty new to Linux-based systems, so if I say something wrong or ask something dumb, please bear with me. I have a project for school that requires some extensive work inside of the latest version of Fedora including screenshots of rather specific things. The VM system at my school runs Fedora 20 like a snail high on paint fumes, and my laptop's VirtualBox doesn't recognize the ISO I got from the official Fedora site, so I feel like I'm out of alternatives aside from formatting over Ubuntu. I'd rather not do that, as I rather enjoy this distro. I am running Ubuntu 14.04 on my laptop. At my login screen, I have the much appreciated option of selecting between a couple of GUI's--specifically, Ubuntu, GNOME, and Cinnamon. I would like to get the Fedora GUI added to this list, but I don't know where to start or if it's even an option. Any and all help is appreciated.

• What's wrong with my grub configuration?

  - by Daniel Medrano

  I have one hard drive with 2 partitions. I had Windows XP and Windows Seven installed. I've deleted Seven partition and installed Ubuntu 11.10 on it. But when I turn on the computer and the grub menu appears on the screen, I can only see my ubuntu installations and a windows 7 loader. I've already got installed windows XP on another partition, but it doesn't boot. If I want to use Ubuntu alongside Windows XP, ¿how can I fix the problem?

• 12.04 boots into terminal after first install. How to boot into GUI permanently?

  - by Deniz

  As a person with a quite limited CLI experience I congratulate myself on installing Ubuntu on an ancient non-pae Fujitsu Amilo M1425 thru the network with mini.iso. However upon reboot I'm met w/ the following: Ubuntu 12.04.1 LTS ubuntu-fujitsu tty1 ubuntu-fujitsu login: for which my specified login during setup is not accepted. (I'm quite sure its correct) Let's assume this screen is passed, how to start the GUI and make it the permanent option during boot? This box will return to a mostly comp-illiterate person, for which the existence of ubuntu will be an enough shock already. Wouldn't wanna leave him w/o the GUI. Other posts here mention the command startx but I probably need a login in the first place.. So "why won't it accept my login & how can I make the GUI-boot permanent?" is my question. Thanks in advance.

• Boots up into Terminal

  - by Jacob Larson

  I am running a 64 bit version of Ubuntu 12.04.1, and I when I boot up, I am thrown (Rather violently. :P) a full-sized terminal, instead of my lovely GUI login screen.. So I looked around and tried the "startx" command, which works like a charm. Only problem is that now, I have no clue how to keep it from booting to the terminal every time, and boot up into the regular GUI with all my stuff. I did install some kernel updates the night before, though I restarted my computer twice after I had done so without a problem. Thanks for your time!

• How to use MythBuntu to send TV signal to a 2nd frontend

  - by Mark Preston

  I guess the a MythTV or MythBuntu backend acts as a "server" for the frontends. I have MythBuntu installed. It runs fine, I can tune live TV, hear the sound, etc. To get this to work, I had to config the Wired Network IP4V settings to Method: Link-Local Only. The Local Backend IP address is: 127.0.0.1 and the info (bottom of screen) says that if there is another frontend, that this IP add. must be changed. 1 - Does this mean changed to the IP address of the 2nd frontend? 2 - What "Method" do I use to make 2 or more frontends? 3 - I have an ethernet switch which currently "sees" the tv signal, sends it to the computer's ethernet port where Mythbuntu makes use of it. 4 - How do I set up the Myth to send it's output (the tv shows) to both televisions? If you know of a How-To, or website, please give the URL or identifying keywords.

• How do I make rsync also check ctime?

  - by Benoît

  rsync detects files modification by comparing size and mtime. However, if for any reason, the mtime is unchanged, rsync won't detect the change, although it's possible to spot it by looking at the ctime. Of course, I can tell rsync do compare the whole files' contents, but that's very very expensive. Is there a way to make rsync smarter, for example by checking mtime+size are the same AND that ctime isn't newer than mtime (on both source and destination) ? Or should I open a feature request ? Here's an example: Create 2 files, same content and atime/mtime benoit@debian:~$ mkdir d1 && cd d1 benoit@debian:~/d1$ echo Hello > a benoit@debian:~/d1$ cp -a a b Rsync them to another (non-exisiting) directory: benoit@debian:~/d1$ cd .. benoit@debian:~$ rsync -av d1/ d2 sending incremental file list created directory d2 ./ a b sent 164 bytes received 53 bytes 434.00 bytes/sec total size is 12 speedup is 0.06 OK, everything is synced benoit@debian:~$ grep . d*/* d1/a:Hello d1/b:Hello d2/a:Hello d2/b:Hello Update file 'b', same size and then reset its atime/mtime benoit@debian:~$ echo World > d1/b benoit@debian:~$ touch -r d1/a d1/b Attempt to rsync again: benoit@debian:~$ rsync -av d1/ d2 sending incremental file list sent 63 bytes received 12 bytes 150.00 bytes/sec total size is 12 speedup is 0.16 Nope, rsync missed the change. benoit@debian:~$ grep . d*/* d1/a:Hello d1/b:World d2/a:Hello d2/b:Hello Tell rsync the compare the file content benoit@debian:~$ rsync -acv d1/ d2 sending incremental file list b sent 144 bytes received 31 bytes 350.00 bytes/sec total size is 12 speedup is 0.07 Gives the correct result: benoit@debian:~$ grep . d*/* d1/a:Hello d1/b:World d2/a:Hello d2/b:World

• Cool examples of procedural pixel shader effects?

  - by Robert Fraser

  What are some good examples of procedural/screen-space pixel shader effects? No code necessary; just looking for inspiration. In particular, I'm looking for effects that are not dependent on geometry or the rest of the scene (would look okay rendered alone on a quad) and are not image processing (don't require a "base image", though they can incorporate textures). Multi-pass or single-pass is fine. Screenshots or videos would be ideal, but ideas work too. Here are a few examples of what I'm looking for (all from the RenderMonkey samples): PS - I'm aware of this question; I'm not asking for a source of actual shader implementations but instead for some inspirational ideas -- and the ones at the NVIDIA Shader Library mostly require a scene or are image processing effects. EDIT: this is an open-ended question and I wish there was a good way to split the bounty. I'll award the rep to the best answer on the last day.

• Hard-copy approaches to time tracking

  - by STW

  I have a problem: I suck at tracking time-on-task for specific feature/defects/etc while coding them. I tend to jump between tasks a fair bit (partly due to the inherit juggling required by professional software development, partly due to my personal tendancy to focus on the code itself and not the business process around code). My personal preference is for a hard-copy system. Even with gabillions of pixels of real-estate on-screen I find it terribly distracting to keep a tracking window convienient; either I forget about it or it gets in my ways. So, looking for suggestions on time-tracking. My only requirement is a simple system to track start/stop times per task. I've considered going as far as buying a time-clock and giving each ticket a dedicated time-card. When I start working on it, punch-in; when done working, punch-out.

• Error - "IR Hardware not detected" - but it's installed/working

  - by Robert

  I am trying to do: Settings-TV-Set up TV signal. During this process I am getting the error "IR Hardware not detected." With the remote, I can select the "try again" button (to re-detect) and it tries again, so the remote works. Plugging in the "IR blaster" doesn't change anything. (I wouldn't expect any difference, but I read a post which said you needed that. I will get Media Center to change channels if I can get that working - but first things first.) I was able to do the setup months ago when I had cable. and everything was fine. I just got DirecTV. (BTW - During the above process, Media Center detects the signal coming in on channel 3. Windows XP Media Center SP3. The TV Tuner card is a Pinnacle TCTV HD PCI. Everything - and I mean everything - has the latest firmware and drivers - as of 4 months ago when I fixed a different problem. So I DON"T WANT TO HEAR the standard answer to check drivers/firmware. THANK YOU.) Thanks for any help.

• Got back Hibernation option, but cannot resume from Hibernate

  - by harisibrahimkv

  In my Ubuntu 12.04, the hibernation option was working well and fine. However, I installed Debian on another partition recently and when I again tried to boot to Ubuntu, I got a message on the boot splash screen saying : The disk drive for / is not ready yet or not present. Continue to wait; or press s to skip mounting or M for manual recovery. After logging into Ubuntu, I find that my hibernation option has gone missing. Is there anyway to recover the hibernation option? EDIT: I solved the disk drive problem and I got the hibernation option back. When I did "sudo pm-hibernate", my system went to hibernation. However, when powering on again, it booted up normally and thus there was no effect of hibernation. How can this be rectified? EDIT1: System - Lenovo ideapad s10-2. EDIT2: /etc/fstab

• Combining Multiple Queries and Parameters into One Operation

  - by shay.shmeltzer

  This question came up twice this week and while the solution is explained in a couple of previous blog entries I did, I thought that showing off the complete solution in a single video would be nice. The scenario is that you have two VOs with queries that are based on a parameter, I showed in the past how to create a parameter form that executes the query - and you can do this for both. But what if you actually need just one value to drive both queries? How do you combine two parameter forms and two buttons into one? This is what this video shows you. The steps are: Creating two parameter forms Setting the value of a parameter in the binding tab Creating a backing bean to execute the code for one button Adding the code to execute another operation Remarking the parts that can be dropped from the screen Check it out here:

• Intel HD graphics on Ubuntu

  - by tiax

  My girlfriend got a new Subnotebook for Christmas (Sony Vayo VPCY21S1E), which comes with an "Intel HD graphics" vga adaptor. When I try to boot the Ubuntu installer from USB, the screen goes blank after a short while, before I even see the Ubuntu logo. However, when I select "nomodeset" in the boot options, I can boot it to the CLI login prompt. When I start X, though, that only works in VESA mode (I've read Intel eventually got rid of Usermode Mode Setting and only offers KMS now, which I've disabled to get it to boot). What can I do to enable a) higher resolution than 1024x768 in VESA b) hardware acceleration for compiz, video playback, etc?

• Homebrewed Headphone Amp Shows Off DIY Resin Casting Process

  - by Jason Fitzpatrick

  Although the guts of this DIY build are worth checking out in their own right, what really caught our eye was the beautiful resin cast case surrounding the build as it’s something that could be adapted to a wide variety of projects. Over at the electronics blog Runaway Brainz they were looking for a slick way to encase an amp project. Rather than go with a project box or similar construction, they did a resin pour and then sanded and polished the resulting encasement. The results are stunning and turn the electronic guts of the amp into a work of art.

• No keyboard input until after GRUB

  - by Dave M G

  I have a computer that I dual boot between Ubuntu 11.10 and Windows 7. I installed Windows first, and Ubuntu second. When I boot, the GRUB menu comes up, showing me the option to select to boot to Ubuntu at the top of the list, and to boot to Windows at the bottom. Unfortunately, as far as I can tell, any key I press on the keyboard (connected by USB) does not get any response, so I can't actually select to boot to anything but Ubuntu (which is the default selection). Once Ubuntu loads and I am at the log in screen, then the keyboard (and mouse) work perfectly normally thereafter. Why would my keyboard not work only during GRUB? And how do I fix it?

• Broadcom STA driver doesn't work well with BCM4313

  - by Oli

  Following on from my other question about our new Samsung Q330, I've noticed that the wireless is incredibly flakey. It can connect but after a little use, especially if it does a lot of downloading at once (read: install something from the Software Centre), the connection stops working. Network Manager still see the connection, there's just no network throughput. I've simple tests like pinging other local network hosts and they just fail. The Samsung Q330 has a Broadcom BCM4313 wifi card (it's proper ID: 14e4:4727) and it's running on the Broadcom STA drivers that Jockey suggests (it didn't work at all without this). I did try installing b43-fwcutter but this just didn't do anything. I was expecting a configuration screen to come up (to select a firmware) but it never did. This page suggests the newer brcm80211 driver might be able to help, but I don't know how to install that. If you think this is the right route, please let me know how one goes about installing it.

• Why does Ubuntu Download recommend 32-bit install?

  - by Warren Pena

  The Ubuntu desktop download screen has a pair of radio buttons you use to select whether you wish to download the 32-bit or 64-bit version. The 64-bit version is labeled "Not recommended for daily desktop usage." If you have a 64-bit processor, why would you not want to use the 64-bit version of Ubuntu? Update for 10.10: They've removed the "Not recommended" label from the 64-bit version and added a "Recommended" label to the 32-bit version. Update for 11.04: Same as 10.10. Update for 12.04: Still says "Recommended" next to 32-bit version of desktop

• LWJGL glRotatef() without rotating axes?

  - by Brandon oubiub

  Okay so, I noticed when you rotate around an axis, say you do this: glRotatef(90.0f, 1.0f, 0.0f, 0.0f); That will rotate things 90 degrees around the x-axis. However, it also sort of rotates the y and z axes as well. So now the y-axis is pointing in and out of the screen, instead of up and down. So when I try to do stuff like this: glRotatef(90.0f, 1.0f, 0.0f, 0.0f); glRotatef(whatever, 0.0f, 1.0f, 0.0f); glRotatef(whatever2, 0.0f, 0.0f, 1.0f); The rotations around the y and z-axes end up not how I want them. I was wondering if there is any way I can sort of rotate just the axes back to their initial position after using glRotatef(), without rotating the object back. Or something like that, just so that when I rotate around the y-axis, it rotates around a vertical axis.

• Ubuntu/Xubuntu install freeze

  I've been trying to install (dual boot) Ubuntu on my HP PC, Link to my specs (click here) I've tried to install Ubuntu with both USB and DVD, same result. The installer will launch, it will load, but then all will freeze in the middle of the loading. Well, I thought it was something wrong with Ubuntu, so I tried Xubuntu instead. Same thing, the installer will go to the loading screen, but then, it'll just freeze at the point where the "loading cursor" appears. Any help would be very much appreciated!

• Ubuntu 12 installation problem

  - by Blisk

  I have made about 30 copies of the Ubuntu installation CD, but there is no way to install it on my laptop. I get a black screen with a blinking cursor or I get a /casper/vmlinuz file not found or I get Invalid or corrupt kernel image. I tried all solutions that I found but no way to install ubuntu on this laptop. I tried both 32 bit and 64 bit versions, I tried ubuntu 11, and no way to install it. Only If I install windows first and than can I install it with wubi. But that is not an ideal solution. That is linux installed on windows. If I install any other distributions of linux the installation works ok. So there must be some issue with ubuntu!
