  • Wired internet speed is slow in Ubuntu 12.04

    - by RameshKatkam
    I have dual boot Windows 7 and Ubuntu 12.04 on my Dell N4110 laptop. I recently installed Ubuntu 12.04 on my existing windows 7 hard drive. I am experiencing very slow internet speed on Ubuntu(wired connection). But on Windows,internet is really fast. I disabled ipv6 by editing /etc/sysctl.conf No avail. Then i run the following command. sudo ethtool -s eth0 speed 100 duplex full autoneg off No benefit. I am having "Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller [10ec:8136] (rev 05)" network card.

  • Cat 6 Only 100mbit speed

    - by Stu2000
    I tried two different cat6 cables directly connected between my two ubuntu machines. This one I ordered online: http://www.amazon.co.uk/gp/product/B002SQPDXS/ref=wms_ohs_product only achieves 100mbit speeds, but does appear to be supporting cross-talk (direct pc to pc), the other cat 6 cable, worked perfectly and gets the full 1gigabit speed. Both tests were performed using ftp and checking the network monitor with direct pc to pc connection. Did the product from amazon lie to me or do I need to manually set a setting somewhere in ubuntu for some cables? I had thought 10 quid for 20m of gigabit ethernet cable was a bit cheap, you get what you pay for... Regards, Stu Update: It seems that after rebooting, the device is set to 1000mbit sec when looking it up with sudo ethtool eth0 However after a while, this will drop down to just 100, after which to reset it to 1000 again, I have to reboot, and simply unpugging and re-plugging in the cable doesn't do it. I tried setting this in networking config file as suggested here: auto eth0 iface eth0 inet static pre-up /usr/sbin/ethtool -s eth0 speed 1000 duplex full but that resulted in my networking failing to start. Is there a problem with my 'auto-negotiation' or something? Can I manually override a setting to 1000mbit?

  • First mouse click not detected

    - by user286169
    Since a few days my mouse reacts different on a click. The first click is not working properly, it seems as it is interpreted as a hoover, the second click is interpreted as the first 'real' click. I tried switching left and right buttons, but behaviour stays the same. Tried restarting unity, implemented ctrl_alt_bksp, but didn't help either. I am running 14.04 Ubuntu, and have all packages up-to-date using apt-get update/upgrade. Is there anybody with a clue? Thanks in advance! Patrick

  • Jquery website is not opening in UBUNTU but in XP, Everything is fine

    - by Raman Sethi
    I know it is weird, But I just discovered this, jquery.com is not opening in my ubuntu firefox or other KDE browser and hence many sites that copy codes from code.jquery.com also hanged. Is there any solution to this problem. I have found the problem It is actually with the DNS servers I am using, Google DNS, 8.8.8.8 and 8.8.4.4, whenever I use these DNS in ubuntu my system stop responding to some sites, actually they are connected nicely, but the request end up in waiting.. I dont understand why...??? I checked my DNS with cat /etc/resolv.conf Even after using Google DNS, it is showing DNS servers I received automatically after connecting to the service provider. I am connecting using Network Manager, not using DNS I provided but using the default one. Any Solution??

  • Alternative software to Freedom and/or Anti-Social?

    - by mummey
    Freedom: http://macfreedom.com/ Anti-Social: http://anti-social.cc/ Simply put: Where can I find a alternative software to either-or/both these apps? Note: Part of the appeal of these apps is allowing the user to explicitly make it extra difficult to re-enable these services. Unplugging the network cable might seem to achieve the same results from an glance, but the added difficulty in re-enabling those services is what makes these apps valuable.

  • Minecraft Fullscreen not working

    - by Straemer
    I upgraded to Quantal recently, and Minecraft seems to not want to run in fullscreen. When I go to fullscreen it, the screen will go black for a second, as if it was about to go fullscreen normally, but then it just restores back into its window. So far I have tried: using different JREs (I've tried openjdk 6 and 7, as well as oracle7). Oracle's jre wouldn't even run Minecraft (I just got a black screen after logging in) switching graphics drivers (tried nvidia-current, nvidia-current-updates, and xserver-xorg-video-nouveau) updating minecraft bin files updating lwjgl libraries separately from the lwjgl site None of this seemed to work at all. I am running Minecraft with the command java -Xmx1024M -Xms512M -cp minecraft.jar net.minecraft.LauncherFrame Graphics card is GeForce 9500 GS/PCIe/SSE2. Everything was working fine a few days ago when I was on 12.04.

  • SMART: DISK FAILURE IS IMMINENT (under 24 hours?)

    - by flix
    I have on my hard drive 2 OSes: Ubuntu 12.04 and Windows Vista( I keep it just because of school). Everything was OK on both OSes,but one day on Ubuntu I was getting awkward noises from my notebooks's hard drive and then everything stops and I couldn't do anything. On Windows everything was ok. Everytime I boot on Ubuntu I can get 5 minutes of normal run, without problems. After that the hard drive sounds crazy and nothing works. I could run S.M.A.R.T tests from a older Ubuntu CD (10.04) from the GUI(Disk Utility, or something like that and from terminal). From the GUI I got that the DISK FAILURE IS IMMINENT and I have ~700 bad blocks(or broken blocks, I had that test I while ago) on my HDD. From the terminal ( I don't remember if it was fsck or a SMART test command) I got that the HDD will fail in under 24 hours. Since then it passed 2-3 weeks. I've tried "badblocks" but after 10 hours it was still running and I had to stop it. Now I have to use cygwin and other alternatives for my linux apps on Windows. PLEASE HELP!!! How can I separate the bad blocks from Ubuntu so it wouldn't use them?

  • Is there a taskbar applet to show the status of a remote host?

    - by Mathew
    At the end of the day I would like to be able to copy files to my home PC just in case I feel inspired to work on them in the evening. But I only want to do this if the PC is on already. (I can remote wake-on-lan the PC but I don't want to always be doing that). I would like some taskbar applet that shows the status of the PC and whether I can ssh into it or not. Obviously it would also be interesting to have an idea as to how long it is on for whilst I am at work as that gives a good indication of whether anyone is in or not. However being able to unobtrusively copy files to the remote machine is the main objective. Perhaps another approach is to run rsync on cron and if the remote host is not up then I guess it will fail. Is that correct? If anyone else has ideas on how to best sync a work and home PC then please do tell.

  • Why are bugs responsible for big deficiencies in functionality given such low priority?

    - by keepitsimpleengineer
    Well, first of all, change is inevitable and mostly good. Furthermore attempts at simplifying the User Interface such as Gnome 3, Unity to make Linux more inclusive hold much promise, even though they adversely affect my style of working. Additionally, though now retired, I have worked with computers for 47 years, and though I do nothing serious for others now, I still do heavy duty things. 10.04 LTS is my big workstation, and I had three 10.10 systems for Mythtv, and one of which is further adapted for video & related. The Mythtv were 10.10 because of a dormant bug regarding installing to 10.04. My work habits consistently use dual monitors and compiz cube and 3D windows with the computing horsepower to support them. The dual monitors with separate X screens has been not been functional since 11.04, and cube/3D windows not functional in Unity, and with diminished functionality Gnome. There is a bug filed (after upgrade to 12.04 amd64 Gnome Classic not properly draw second screen) I have mitigated the situation some by switching to Xubuntu and eschewing Unity. The question that comes to mind is why this bug is not given more attention in that it nearly cuts functionality in half for more competent workstations. Sample workspace... Please know that I appreciate all the hard work, dedication require to pull off something as big as Ubuntu et al.

  • How can I force the (re)discovery of PulseAudio network sound devices?

    - by Christian
    I'm using the PulseAudio feature of network sound devices (not Multicast/RTP) to play sound from my netbook on the audio equipment connected to the HTPC when at home. This creates a virtual sound device that I can then use instead of the physical built-in one. Most of the time this works just fine. Sometimes however, the virtual sound device just doesn't appear. Disconnecting from and reconnecting to the network helps sometimes but not always and it's annoying and potentially bad for existing TCP connections. So my question basically is: Is there some way to tell PulseAudio "Hey, just look again if you really can't find a network sound device."? Edit: Unloading and reloading the module-zeroconf-discover with pacmd does not help either and it doesn't appear to be an avahi problem per se since avahi-browse -t --all | grep PulseAudio shows lots of right-looking stuff, even when the devices aren't listed in pavucontrol or pacmd list-sinks. Edit 2: I'm using Ubuntu 12.04 on both boxes for all the difference it might make.

  • Forward TCP Connections with Iptables

    - by opc0de
    I receive connections to my server from several ip addresses I want to route these connections just like rinetd does but based on the ip the connection is coming from to connect to a specified host. Just like this: IP 10.10.12.1 => CONNECTS TO MY SERVER => MY SERVER REDIRECTS IT TO 82.12.12.1 IP 10.10.12.2 => CONNECTS TO MY SERVER => MY SERVER REDIRECTS IT TO 81.121.12.10 etc Is it possible or do I need to write my own daemon to achieve this functionality ?

  • Disable ATI Radeon graphics card and use intel graphics (switcheroo unavailable)

    - by user92356
    So I have a HP Envy with ATI Radeon 5450 + intel switchable graphics. I think (though I'm not sure) that the Radeon is running right now on Ubuntu 12.04 (because my laptop is making too much noise when I'm doing something non gpu intensive like word processing, or web browsing). So what I want to do is disable the ATI Radeon and use the Intel instead. I looked around and it seems all the solutions use switcheroo, but I dont have it on my computer! I think this happened because I tried installing the proprietary driver (fglrx). Any and all help is 200% appreciated, thank you

  • Why does starting a program log me out?

    - by Bruce McKean
    I'm not a computer nerd but have been able to fix Ubuntu/Linux problems in the pass two years with a Google search but this on has me stumped. I upgraded to 12.04 about thirty days ago and all was well except that every time I tried to load KeePassX it would go to the login screen. I installed KeePass2 and all seemed to work. Last week I tried to load Bibble5 (Raw photo editor) and it would try to load and then back to the login screen. After a few days I gave up and downloaded Corel After Shot Pro (Corel's now owns Bibble5) and it has the same problem. Could someone please head me into the steps I need to follow to find out what is the cause? I'm interested in learning more about the Linux system. How to correct any future problems like this? Computer Specification: Processor : 8x Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz Memory : 8155MB (1092MB used) Operating System : Ubuntu 12.04 LTS Graphics Card : GeForce GT 520/PCIe/SSE2

  • Ubuntu 12.04 Automounting ntfs partition

    - by kuzyt
    Ive looked everywhere to fix this problem but I cant seem to figure out why its doing this. I have the following /etc/fstab entry to mount a ntfs partition using ntfs-3g. UUID=01CD842715EC2180 /media/mediahd02 ntfs defaults,user,noexec,uid=1000,gid=1000,dmask=007,fmask=117 0 2 The volume label for this partition is "MEDIA02" So I have had no problems with the fstab mounting. The problem however is that it automounts again using MEDIA02 label. I'm not sure automounting is the right term for this as its just an empty directory. Deleting this directory and rebooting is causing it to appear again. So listing /media I see both MEDIA02 & mediahd02 htpc@htpc:~$ cat /etc/fstab # /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed.

  • Disable auto-mount for particular partitions on usb drives

    - by nealmcb
    I have a big USB disk with 3 partitions: one for backup and two other bootable ones for installing and testing new distros. I want the backup partition automounted on boot. But I don't want the two test partitions automounted. Despite my use of "noauto" in /etc/fstab, something (gnome?) seems to be mounting them when I plug the drive it. LABEL=mybook /srv/backup ext4 defaults 0 2 LABEL=mybook-root /media/mybook-root ext4 user,noauto 0 2 LABEL=mybook-spare /media/mybook-spare ext4 user,noauto 0 2 In previous Ubuntu distributions it seems that it was possible to configure gnome so it would avoid mounting particular partitions on removable drives like USB: gnome-mount --write-settings --mount-options noauto --device /dev/sda1 This is no longer available in Lucid (when did it go away?) Is there another way to do this now?

  • LibreOffice Math problem with greek letters

    - by Matheus de Araújo
    I've a problem with my LibreOffice. Using an old archive that I have (with the Maxwell's equations), the greek letters are like squares. I tried to change something in the alphabet but even the font don't have any greek letters (they appear like squares too), both Greek and iGreek letters package. Sounds like a packet that isn't installed or corrupted, but I still redownloaded and reinstalled the LO and I don't know whose I have to install. With the OO my equations worked well (I made the file with it). What am I supposed to do?

  • failed to get i915 symbols, graphics turbo disabled error on boot

    Whenever I boot my laptop, I see this message and it makes the boot process very slow as my screen stays black for a long time before this message appears. It shows just for a split second but today It got worst when my system couldn't boot and stuck on this error, I did several reboots but still couldn't pass this boot error message, then after sometime it fixed itself and now I can use my system as normal. I didn't pay much attention to the error when It was there for just a split second and making my boot process slow, but now that it has stopped me from booting into my system, I would like to know why this error occurring.

  • Dualboot harddisk encryption

    - by amfcosta
    I have a system with both Ubuntu 11.10 and Windows 7 and I want to encrypt the whole harddisk or at least some of my partitions. My partition table is something like this (the ones marked with * are the ones that need to be encrypted): Windows boot reserved partition *Windows system partition (ntfs) *Windows data partition (ntfs) Ubuntu root partition (ext4) *Ubuntu home partition (ext4) Ubuntu swap As I said I don't need to encrypt the whole disk. What is the best way to accomplish this? Maybe something (TrueCrypt?) where I enter the password before the system boots so that it decrypts the whole hdd? Or maybe individual encryption using Windows-only encryption (for Windows partitions) and Ubuntu home encryption (well, for Ubuntu home partition)? By the way, I almost always use Ubuntu, so it would be nice if I could continue to boot Ubuntu by default but have an option to boot Windows too (like in grub). EDIT: I was thinking of doing this: encrypting ubuntu home with eCryptfs (I think this is used to encrypt home when selected during installation). Encrypting Windows partitions with TrueCrypt. Still having Grub as a bootloader, when I choose ubuntu everything goes as normal (home is decrypted when login in). When I choose windows the TrueCrypt password prompt shows and windows boots.

  • How can I assign custom icons to folders?

    - by Frank Souza
    How do I assign custom icons to folders, as well as the default folders Desktop, Downloads, Music, etc.? I know that one way is to assign the properties of folders, but I want to assign icons in the same way that are assigned the default folders, so the custom icons will also appear in the Nautilus bookmarks. I've also seen this question custom icon in "Places" menu <<, but that is not what I seek. UPDATE My main intention is this: I want the markers to display custom icons like the dolphin. I know it's possible, because the folder "Desktop", "Documents", "Music" has its own custom icons in bookmarks. How?

  • Which of VLC's dependencies causes sound device detection?

    - by Raphael
    I am setting up a headless music server based on the minimal Ubuntu image. After having installed the packages openssh-server,pulseaudio, libmad0,flac,liboff0,libid3tag0,libvorbis0a,ffmpeg, mpd,mpc,mpdscribble, paman,paprefs,pavumeter neither my internal soundcard nor the external DAC where detected by pulseaudio, that is pactl list did only list the dummy devices. Several reboots did not change that. The hardware devices are detected properly: ~$ lsusb | grep Texas Bus 002 Device 002: ID 08bb:2706 Texas Instruments Japan ~$ lspci | grep Audio 00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 02) Following a hunch, I installed vlc with all dependencies. After a reboot, both devices are detected! ~$ pactl list | grep "Sink: alsa_output" Monitor of Sink: alsa_output.pci-0000_00_1b.0.analog-stereo Monitor of Sink: alsa_output.usb-Burr-Brown_from_TI_USB_Audio_DAC-00-DAC.analog-stereo Now I would like to remove VLC again but keep the devices. The question is: which of the many dependencies of VLC enables proper device detection? And why on earth is it not a dependency of pulseaudio?
