  • How can I reduce lagging with GUI/GPU stuff -- make Unity run smaller, quicker, faster?

    - by chris
    Finally installed Ubuntu 12.04 on my HP Pavilion 2000. Have all of my apps on and loaded and am happy thus far. ONE ISSUE -- I'm experiencing a small amount of GUI/GPU style lagging when I go to open menus, move windows, etc. What settings can I disable to allow it to run sharply and quickly, even if i t means sacrificing some of the graphics? Have already installed pre-load. Just want the OS to run sharply and quickly with menu refreshes, window moves, etc. I do not mind sacrificing graphics. Somone mentionted to me I have to install video drivers but the two that come up in system settings under drivers it won't let me install. ALSO : I am driving a second 19" monitor -- would that make a difference performance wise as well? Thanks in advance. Chris

  • Ubuntu 10.04, I cannot get my computer to connect to the internet

    - by Jared Isaacson
    So at first I was unable to get my Belkin Surf & Share usb to install on my computer, so then I plugged my computer directly into my router and my computer won't acknowledge any connection. I know very little about how to use ubuntu, please help me. What I do know is: I'm using Ubuntu 10.04 Lucid Lynx In my 'edit connections', I go into 'wired' tab, select "wired connection 1" then 'edit' it brings up 4 tab options: Wired (I input the MAC address that's printed on the bottom of my router, MTU is set to automatic) 802.1x Security (currently: not checked) IPv4 Settings (currently: Automatic (DHCP) addresses only) IPv6 Settings (currently: Automatic)

  • Brightness issues on MSI GT683

    - by Mitu
    I'm experiencing brightness related issues on my MSI GT683 (Intel Core i5-2410M, nVidia GeForce GTX 560M, Ubuntu 12.04 LTS x64, nVidia driver version 295.40). To start with, when I open brightness settings, the slider is working incorrectly - screen is the dimmest on about 1/3 of a bar, moving it to the left side increases brightness. Next, while pressing the keyboard buttons (Fn+up, Fn+down), brightness changes incorrectly - sometimes 2 steps up/down, but sometimes it's totally irregular - ex. in order to set the lowest brightness, I have to set the maximum, then hit Fn+down, then Fn+up. (after 2 moves from 8 to 2... What's even more strange, while changing brightness from keyboard on boot and on login screen, it works perfect. Tried adding acpi related switches to GRUB, but the brightness settings wouldn't work at all. Any help appreciated.

  • No dual boot option, no boot priority order

    - by Atul
    I installed Ubuntu yesterday. I partitioned my C: when it was asked to give memory allocation to Ubuntu. The version is 12.04. I was able to install Ubuntu completely: Ubuntu is successfully installed. Restart you computer. I restarted and there was no Ubuntu option. Windows 7 also asked for a boot repair. So I did that too. I then wanted to change my boot priority order to Ubuntu but couldn't find it in BIOS section. I allotted 20GB to Ubuntu and it is deducted from C: but I couldn't see the partitioned drive in Windows 7. Wubi was working fine before on PC with dual boot option. I used Linux Live key creator to boot my PC through pen drive.

  • It's noisy in ubuntu,why?

    - by Jinx
    I just installed an ubuntu on my pc(Dell Inspiration I560SR-358, with CPU E5700 3GHz, 4G memory, and NVIDIA GeForce G310). The pc becomes noisy before that it's quiet with a windows 7 on it. How come? How to set it to be quiet again in unbuntu 10.04. One of the two cpu usage is always 100%. I think that is the reason. //re-edit Everything gets ok after I restart the computer.But the fan is still running which makes it noisy, if i switch to windows 7, it becomes quiet again.

  • Where is Kile's dictionary?

    - by user2413
    Hi, I've accidentally added 'itterative' to Kile's dictionary (right click on the wrong button). Now I'd like to remove 'itterative' from the list of correct words but I can't locate the dictionary anymore (the old link in settings-configure kile ) does not link to where it used to... Thanks in advance, PS: I use Kile as out of the box...no special settings no-nothing EDIT To adress Oli's answer below. Kcontrol is not in the 10.10 reps (apparently) downloading the .tar.gz version of kcontrol and install it, by typping: cd ~/Documents/khepera SUBDIRS="libtns_util libxfgc libkhepera kcontrol" for i in $SUBDIRS ; do make -C $i install; done for i in $SUBDIRS; do make -C $i clean; done for i in $SUBDIRS; do make -C $i tgz; done creates load-full of errors. I guess they could be solved, but it seems of an overkill just to locate Kile's dictionary. Any other ideas?

  • Downgrade to LTS version, preserving /home partition: Should I expect this to work?

    - by Archelon
    Specifically, I'm installing Kubuntu 12.04 over 13.04. And in fact I've already done it, and it seems to have at least mostly worked, but I'm wondering whether this one anomaly is likely to be attributable to the downgrade; to wit: I have no window borders|decorations, but only wide, featureless, white---or sometimes black---margins around all my windows. None of the settings in System Settings (the window border and decorations options are in Workspace Appearance) seem to have any effect. Is this likely to be fixable, or should I cut my losses and reinstall (formatting the /home partition and restoring any data with rsync)?

  • How to Access Your Router If You Forget the Password

    - by Chris Hoffman
    Routers protect their web interfaces, where you can configure their networking, parental control, and port forwarding settings, with a username and password. These default passwords can be changed to protect the router’s settings. If you’ve forgotten a router’s password – or if you acquired a used router and don’t know its password – there’s a way to reset the password. You may also be able to forward ports without knowing the password.

  • Where are bluetooth received files saved

    - by Luis Alvarado
    I have used Blueman and the default Bluetooth manager an every time I accept the file transfer from the Phone to the PC, it shows that it is transferring and even notifies me that the transfer was successful but I can not find the image anywhere. Where are files stored after sending them via Bluetooth to the PC? I already checked my Home folder. The Picture folder which I thought it would be the one for images. Then the document folder and afterwards I did a huge check on all folders under /home. No luck. Is nowhere. I even checked this answer with no luck.

  • Used DBAN to wipe Lenovo u410 then installed Ubuntu. Need to install windows 8, but I get an error.

    - by David
    When I try to boot from my windows 8 USB (tested on a separate PC), I get this error text "The boot configuration data for your pc is missing or contains errors." I want to install windows again so I can fix a battery issue I'm having. Lenovo's power management app has an option to keep the battery at 60% if the laptop stays plugged in most of the time. I enabled this, then formatted without changing it back. I think there might be a raid setup that I may need to remove or something. I don't mind removing Ubuntu and starting fresh. I would just love some help with all this, I'm a noob when it comes to Linux.

  • Getting Wacom Bamboo Pen + Touch pressure sensitivy in GIMP

    - by Bart van Heukelom
    I've installed my Wacom Bamboo Pen + Touch (CTH-460) in Ubuntu (at least on one system, not another) and the pen works well for controlling the mouse cursor. However, I can't get pressure sensitivity to work in GIMP. I have 4 extra devices in the input devices settings screen now, two of which are the pen and eraser. I've set them both from Disabled to Screen, and left the default settings intact. However, after saving I still don't see any pressure options in the brush tool's options. I've also tried setting the mode to Window instead, but it makes no difference regarding pressure sensitivity. There are no other modes. The pressure works out-of-the-box in Blender (grease pen) so it must be something in GIMP. What can be wrong? Why don't the options appear? How can I debug this?

  • Need to convert a video file from mp4 to xvid

    - by Shawn
    I checked out the questions with similar titles and didn't find anything that I thought would help. I am attempting to convert a video into an avi, preferably xvid. The video file's Video and Audio Properties are as follows: Video Dimensions: 1280x544 Codec H.264/AVC Framerate: 24 frames per second Bitrate: 774 kpbs Audio Codec: MPEG-4 AAC audio Channels: Stereo Sample Rate: 48000 Hz Bitrate: 32 kpbs I have tried numerous times to convert this into an Xvid codec AVI but I have had no luck successfully getting the audio to sync properly. I am using Openshot to attempt conversion, using the libxvid codec and AVI format, but I am unsure of the proper audio settings I should use. What settings should I use to convert this video with Openshot? If it is not possible with Openshot, or if there is a better application to use, I would be grateful to know that as well.

  • Warning about SSL ceritificate, am I under attack ?

    - by Bunny Rabbit
    Lately I've been getting a lot of warnings about SSL certifications on my pc, Empathy keeps telling me that Facebook's certificate is self-signed and can't be trusted, and also, there are occasional warnings in Google-Chrome about security. I remember the last one saying that that the page is secured but some of the resources that the page is using are not from a secure connection, something like that. Is my pc hacked / under attack? How can I check that, and if so, how can I safeguard myself? PS: One thing that comes to my mind is that I might be under an arp poisoning / spoofing attack.

  • Ubuntu systematically losing wired connection

    - by Lukasz Baczynski
    I'm working on 11.10 for few recent days, everything was working perfect until today. Updated ubuntu (some certs were updates as far as i remember) and from this time, wired network stops working randomly and systematically. (All other pcs/macs work fine) From 192.168.0.9 icmp_seq=25 Destination Host Unreachable From 192.168.0.9 icmp_seq=26 Destination Host Unreachable From 192.168.0.9 icmp_seq=27 Destination Host Unreachable From 192.168.0.9 icmp_seq=28 Destination Host Unreachable From 192.168.0.9 icmp_seq=29 Destination Host Unreachable From 192.168.0.9 icmp_seq=30 Destination Host Unreachable From 192.168.0.9 icmp_seq=31 Destination Host Unreachable 64 bytes from 192.168.0.1: icmp_req=32 ttl=64 time=1003 ms 64 bytes from 192.168.0.1: icmp_req=33 ttl=64 time=0.496 ms 64 bytes from 192.168.0.1: icmp_req=34 ttl=64 time=0.576 ms 64 bytes from 192.168.0.1: icmp_req=35 ttl=64 time=0.522 ms 64 bytes from 192.168.0.1: icmp_req=36 ttl=64 time=0.624 ms 64 bytes from 192.168.0.1: icmp_req=37 ttl=64 time=0.625 ms 64 bytes from 192.168.0.1: icmp_req=38 ttl=64 time=0.555 ms It'll work for 20 seconds then it'll stop working for 10-30sec and so on.

  • After suspend, my monitor wont turn back on

    - by David
    I set my pc to suspend after 5 minutes of inactivity, when I return to my computer I mash a couple of keys and the pc turns back on and the drives start spinning etc etc, but I get no signal to either of my monitors. My peripherals are powered as the num/caps lock lights turn on and off. I should add I have two monitors, I have the same problem on both. As I am writing the last line from my previous paragraph keeps disappearing. I press control z and it comes back but kinda weird. Thanks in advance for any help :)

  • Why are Javascript for/in loops so verbose?

    - by Matthew Scharley
    I'm trying to understand the reasoning behind why the language designers would make the for (.. in ..) loops so verbose. For example: for (var x in Drupal.settings.module.stuff) { alert("Index: " + x + "\nValue: " + Drupal.settings.module.stuff[x]); } It makes trying to loop over anything semi-complex like the above a real pain as you either have to alias the value locally inside the loop yourself, or deal with long access calls. This is especially painful if you have two to three nested loops. I'm assuming there is a reason why they would do things this way, but I'm struggling with the reasoning.

  • Local Entities with NHibernate

    - by Ricardo Peres
    You may know that Entity Framework Code First has a nice property called Local which lets you iterate through all the entities loaded by the current context (first level cache). This comes handy at times, so I decided to check if it would be difficult to have it on NHibernate. It turned out it is not, so here it is! Another nice addition to an NHibernate toolbox! public static class SessionExtensions { public static IEnumerable<T> Local<T>(this ISession session) { ISessionImplementor impl = session.GetSessionImplementation(); IPersistenceContext pc = impl.PersistenceContext; foreach (Object key in pc.EntityEntries.Keys) { if (key is T) { yield return ((T) key); } } } } //simple usage IEnumerable<Post> localPosts = session.Local<Post>(); SyntaxHighlighter.config.clipboardSwf = 'http://alexgorbatchev.com/pub/sh/2.0.320/scripts/clipboard.swf'; SyntaxHighlighter.brushes.CSharp.aliases = ['c#', 'c-sharp', 'csharp']; SyntaxHighlighter.all();

  • Add Reference with Search

    - by Daniel Cazzulino
    If you have been using VS2010 for any significant amount of time, you surely came across the awkward, slow and hard to use Add Reference dialog. Despite some (apparent) improvements over the VS2008 behavior, in its current form it's even LESS usable than before. A brief non-exhaustive summary of the typical grief with this dialog is: Scrolling a list of *hundreds* of entries? (300+ typically) No partial matching when typing: yes, you can type in the list to get to the desired entry, but the matching is performed in an exact manner, from the beginning of the assembly name. So, to get to the (say) "Microsoft.VisualStudio.Settings" assembly, you actually have to type the first two segments in their entirety before starting to type "Settings"....Read full article

  • In a multidisciplinary team, how much should each member's skills overlap?

    - by spade78
    I've been working in embedded software development for this small startup and our team is pretty small: about 3-4 people. We're responsible for all engineering which involves an RF device controlled by an embedded microcontroller that connects to a PC host which runs some sort of data collection and analysis software. I have come to develop these two guidelines when I work with my colleagues: Define a clear separation of responsibilities and make sure each person's contribution to the final product doesn't overlap. Don't assume your colleagues know everything about their responsibilities. I assume there is some sort of technology that I will need to be competent at to properly interface with the work of my colleagues. The first point is pretty easy for us. I do firmware, one guy does the RF, another does the PC software, and the last does the DSP work. Nothing overlaps in terms of two people's work being mixed into the final product. For that to happen, one guy has to hand off work to another guy who will vet it and integrate it himself. The second point is the heart of my question. I've learned the hard way not to trust the knowledge of my colleagues absolutley no matter how many years experience they claim to have. At least not until they've demonstrated it to me a couple of times. So given that whenever I develop a piece of firmware, if it interfaces with some technology that I don't know then I'll try to learn it and develop a piece of test code that helps me understand what they're doing. That way if my piece of the product comes into conflict with another piece then I have some knowledge about possible causes. For example, the PC guy has started implementing his GUI's in .NET WPF (C#) and using LibUSBdotNET for USB access. So I've been learning C# and the .NET USB library that he uses and I build a little console app to help me understand how that USB library works. Now all this takes extra time and energy but I feel it's justified as it gives me a foothold to confront integration problems. Also I like learning this new stuff so I don't mind. On the other hand I can see how this can turn into a time synch for work that won't make it into the final product and may never turn into a problem. So how much experience/skills overlap do you expect in your teammates relative to your own skills? Does this issue go away as the teams get bigger and more diverse?

  • Default User Id at Login different from User Name in Terminal Shell

    - by Bill
    During the Ubuntu 12.04 LTS installation, I was prompted to enter a user name and password, so that a corresponding account could be created and set up for login. I replaced the one that was provided by default (i.e. '70319', which is the Windows 7 admin id) with a user name/id of my choosing. Now, when I turn on the computer, and choose to enter the Ubuntu operating system, the login id that is displayed is 70319 - that is, the one provided by Windows 7. However, when I open up a Unix/Terminal shell, the user id that is displayed at the prompt is the one I entered during installation. Otherwise, the installation of Ubuntu was a success! Is there some way of changing the user id that is displayed at the Login screen, so that it is consistent with the one I entered during installation? If it's any help, I installed Ubuntu using wubi on an ASUS Eee PC 1011PX running Windows 7, and ASUS Express Gate Cloud. Further details regarding the setup/installation can be found at the following link: Installing Ubuntu on an Eee PC 1011PX
