  • Audio codec consuming high battery power

    - by Vamsi Emani
    My powertop reports this for the two audio codec components. 4.85 W 100.0% Device Audio codec hwC0D3: Intel 4.85 W 100.0% Device Audio codec hwC0D0: Realtek I think 10 W for audio is too high. Can somebody please suggest me a way to reduce the power consumption? It'd be nice if someone could educate me on this, I have an idea about codecs in general but I have no clue about their internals? Why is it that these two components keep running always even when I am not listening to audio?

  • How to use GCC 4.7 in place of 4.6 (Ubuntu 12.04)

    - by Larz Conwell
    So I'm working on a project and I wanted to use some C11 features for C. To use those features GCC 4.7 is required, so I went to synaptic and looked up 4.7, and I found the packages gcc-4.7-base so I installed it[1]. So now that gcc-4.7-base is installed I expected to be able to use 4.7, but no, when I do gcc --version it still shows 4.6.3 even more, when I try to directly call 4.7(via /usr/bin/gcc-4.7) it doesn't exist, though a gcc-4.6 executable does exist. How do I "activate" GCC 4.7? I read here, you do some crazy stuff with update-alternatives, but it doesn't work for me as the gcc-4.7 executable doesn't actually exist on my machine. Notes: 1. I also saw gcc-4.6-base, so I figured I'd uninstall it, but synaptic attempted to remove every package I had installed and install a Java runtime, so for obvious reason I decided not to remove it.

  • Serious error on first attempts to dual boot Ubuntu 14.04 with Win7

    - by beetle
    I downloaded Ubuntu 14.04 from the website which I saved to my desktop with WinRar. My trial with winrar had expired so I have now tried it with Active@Isoburner but I'm getting no further. I eventually got it burnt onto a DVD(4.7gb) and tried to boot from DVD and normally. Neither way works. It looks like its about to boot but then a message appears saying that a serious error has occurred...the disk drive for /tmp is not ready yet or not present...press I to ignore, s to skip or m for manual... At this point I'm lost and unsure what to do. My laptop Toshiba Equium A210-17I is over 5 or 6 years old. Available space on the Hard Drive is 24gb. 2gb RAM. It originally came with Windows Vista Home Premium edition but about a year ago or more a friend wiped it clean for me as I was having no end of problems with Vista. He installed Windows 7 Ultimate(which I don't have a disc for). How can I resolve this issue and get Ubuntu to boot up? Do I have to install a previous version of Ubuntu first? Any advice or help would be greatly appreciated. Kind regards. Beetle.

  • Ubuntu One API Java - how to use REST and AccessToken?

    - by Michael
    I am writing a java app in eclipse that backups data to several consumer-cloud-services encrypted and redundant. So far, I successfully implemented the authentication process, as it is described in the documentation. At this point, I do not know how to proceed. The next step would be implementing the auth with the stored AccessToken and afterwars implementing upload/download/listing functionality through the REST API. I think I have to store the String oauth.getSerialized(). How do I authenticate with this String afterwards? This does not work e.g.: AuthenticateResponse oauth = api.authenticate(serialized); api.setAuthorizer(new OAuthAuthorizer(oauth)); Can someone tell me please, how I can use the REST API with java? There is no explanation or link in the developers area as far as I saw. And btw, I wasted at least one hour trying to fix errors, because some needed libraries are listet after the example code. :/

  • How do I get back hard drive space after I have uninstalled Ubuntu from Windows?

    - by Shantanu
    I installed Ubuntu on windows like it says to do it on Ubuntu's website as an application. I did not want it to create a separate partition on my hard drive. A few days ago, I uninstalled Ubuntu by going into the Windows control panel and hitting uninstall. As you would expect, I would get back my 100 or so gb on the disc. i never really installed anything of importance on ubuntu so i never had a second thought about uninstalling it. But I never got back my 100gb from Ubuntu. Now when I add up all of the folders on my c drive, they total to the amount I had on windows before I uninstalled Ubuntu but when I look at the My Computer screen, it says that another 100 or so gb is missing. I tried defragmenting the disc, downloading various disc managers but nothing fixed the space problem. Can anyone please help me with this!!??? Any help is much appreciated! Just making sure: UBUNTU WAS NOT ON A SEPARATE PARTITION, IT WAS INSTALLED AS AN APPLICATION ON WINDOWS. It tells yuo how to do this here except i did it with a much older version (i think it was 8.04 or soemthing): http://www.ubuntu.com/download/help/install-ubuntu-with-windows

  • Opening a NTFS partition fails with report: Not authorised

    - by Dugi
    Besides lesser errors on 11.10, I ran into a more annoying one: I cannot access NTFS partitions. No matter whether I use nautilus, dolphin, tux commander or archive manager, always does the same thing, could not mount 'disc name': Not authorised' There were several fixes of problems with access to NTFS partitions, but none of them helped. When I used nautilus in sudo mode, the partition looked empty, although when I booted on windows, there were files. It was reported as a bug somewhere. Can anyone help me?

    - by jippie
    The Arduino IDE is based on a java application called processing. While typing text into processing, it refuses to accept any of the characters under dead keys like " ' ^. As a work around I: Open another window (usually my browser or mail client); I type the character I need; Select and copy the character onto my clip board; Copy the character into processing. What do I have to do to make processing accept characters under dead keys? Disabling dead keys is not an option.

  • Compiz slow under proprietary nvidia driver

    - by gsedej
    Hi! I am using Ubuntu 10.10 and have problem with proprietary nvidia driver for my GeForce GTS 250. I have issue with poor Compiz performance. And there is also open-source "noueau" driver. Proprietary: I tried many versions but neither works fast on desktop. This means 30 FPS without heavy effects. Currently I am using version 270.18. Even normal desktop use feels bad (moving windows) In games (and 3D benchmark) it is really good! (Unigine Heaven works good!) Open-source "nouveau": Very fast on desktop with heavy effects (blur, ...). I have 300 FPS and more, even in Expo mode. Games were good but not as good as prop. And driver causes xorg to crash even the latest (ppa:xorg-edgers/nouveau), so I switched back to proprietary. I also have computer with Ubuntu 10.04, GeForce 8600GT and drivers around 185.x and Compiz works great there. There is similar question Nvidia proprietary driver performance in 10.10 Which version of nvidia (prop) driver is fast in Compiz in Ubuntu 10.10? How do you install a specific version of nvidia driver? Is it the case that each newer driver works slower on compiz?

  • 14.04 LTS Unity no longer boots after last 94 MB update

    - by Harryg123
    I am running 14.04 LTS, Unity, on an HP Pavillion 15, 4GBRAM, 750 GB hdd, I-5 machine, with AMD 8600M graphics card built in. I have disabled the dash and all Ubuntu spyware. I have been faithfully loading all updates as they appear. This morning it asked for a 94 MB update (bringing kernel to .27, I think. Now, I can boot, get to login screen, but it freezes after that. Keyboard doesn't work at that point, but mouse does. I booted into recovery mode, tried to run in generic graphics mode, -- system again froze. I also pressed [esc] during boot, but saw nothing strange; then text disappeared and was replaced by login screen. I am not a hobbyist; this is a production machine and I have a lot of work to do today. Having a standard software update render my machine completely useless... sigh. Perhaps the simplest thing to do would be to revert to the previous configuration. How do I do that? I can boot into recovery mode. But I have no idea how to proceed. TIA for all help. -Harry

  • notify-send ignores timeout?

    - by Hooked
    Maybe I'm doing something wrong, but shouldn't the commands (run separately) notify-send -t 1 "test" notify-send -t 1000 "test" notify-send -t 10000 "test" Have different timeouts? The first being nearly instantaneous, the second one taking 1 sec and the third 100 seconds. In all cases it seems to take about six seconds. I'm using the development branch of Precise, if this isn't an issue in the released version I'll close this as being too localized, but I'm unable to test it now.

  • Ubuntu and Surface Pro, wifi issues not fixed?

    - by Confused or too stupid
    Just a quick question, from the numerous other threads I found, is the wifi still a no go straight out of installing Ubuntu? I tried this Dual boot Surface Pro with Ubuntu? with 13.04, the wifi is sporadic in working. From that and other threads I gathered that 13.10 would include the fix, so I tossed that onto the Surface as well, with the same results. Is there anything I am missing? Is there any other distro that has better luck with the Marvell chip?

  • Problem with sound driver

    - by JiminP
    I had problem that sound had lag in Flash. (Other than that, there was no problem.) On the internet, I found that installing OSS4 might help me. So I installed OSS4, but there was some problems (no sound on Flash, and couldn't use function key on the laptop - which is quite annoying), so I try to remove OSS4 and re-installing sound modules. After some mess-up, the whole sound was gone. I used Ubuntu for a year, but I don't know how to use the terminal well (All I know is basic commands like sudo, ls, or apt-get).. Now I'm trying to recover by following instructions at this page, but I have some problems... :( When I try to follow instructions: sudo aplay -l finds no sound drivers. find /lib/modules/'uname -r' | grep snd (backtick changed to ' due to code markup) returns nothing. When I try to do sudo apt-get install linux-restricted-modules-'uname -r' linux-generic, it says that it can't find linux-restricted-modules-3.0.0-13-generic package. lspci -v | grep -A7 -i "audio" returns this, which doesn't contain anything about the name of the driver. Writing sudo modprobe sn and pressing tab twice only returns sudo modprobe sn9c102. sudo aptitude --purge reinstall linux-sound-base alsa-base alsa-utils linux-image-'uname -r' linux-ubuntu-modules-'uname -r' libasound2 returns this, and didn't change non of above. sudo apt-get install linux-alsa-driver-modules-$(uname -r) fails because it can't find the package linux-alsa-driver-modules-3.0.0-13-generic. Compiling ALSA driver doesn't work. When I try to make, it says that /lib/modules/3.0.0-13-generic/build/include/linux/modversions.h doesn't exist. I'm using Ubuntu 11.10. Can anyone help me? I can re-install Ubuntu, but I don't want to....

  • Ubuntu won't connect to wired network

    - by djeikyb
    I'm running 10.04, upgraded from 9.10, maybe, but probably not upgraded from 9.04. I have two wifi routers. Zeus is connected to the dsl modem. Hermes uses a wds bridge with Zeus to extend the network. My desktop (Daedalus) is ethernetted to Hermes. My laptop (Clyde) is wifi, switching to Hermes or Zeus as needed. Occasionally, as in whenever I transfer a large file from desktop to laptop, the wds bridge will die. Fixing it means restarting both routers, though it seems Hermes should boot first. This is ridiculous, and eventually I'll get around to asking you guys to help me stop it from happening. More importantly is that my desktop requires a reboot to get back on the network. WTF. ifconfig shows my nic has no ip. /etc/init.d/networking restart doesn't do anything, not even give me a lousy ip. dhcpcd eth1 grants me an ip address, but doesn't help with internet access. route -n shows what looks like my normal routing table, but pinging google.com informs me it's an unknown host. jake@daedalus:~$ route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 10.1.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth1 0.0.0.0 10.1.1.1 0.0.0.0 UG 0 0 0 eth1 It may be worth noting that I can ping both Zeus (10.1.1.1) and Hermes (10.1.1.4) and my laptop (10.1.1.55). Much obliged for any help. Rebooting is, well, trivial in this instance. But it's stupid. I switched to linux because I like the idea that if one part breaks, you fix it instead of reboot reboot reboot. I've left my poor desktop in disarray, confining myself to my little netbook. My desktop is broken, awaiting magical commands from you brilliant folk. (and yes, i know clyde the netbook should be named icarus. it was its original name. ironically the ssd burned out, and i felt it wasn't right when it came to reinstalling)

  • LibreOffice Math problem with greek letters

    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?

  • Setting primary internet connection and network on notebook

    - by Francois
    I have installed Ubuntu on a notebook that I have configured to connect to the internet using an Iburst USB modem. This works 100% after a bit of configuring. I now have a desktop pc that I have installed ubuntu on, and would like to connect the two with a router. I bought a router with wifi, and would like to connect my notebook to the other computer using wifi, while still keeping the internet working with the usb modem. The problem is that as soon as the wifi connect, the internet connection dies. Is there a way to force ubuntu to get internet access through the usb modem, but use wifi to connect to the network? I am pretty new to ubuntu so any help would be appreciated. I also have a samsung galaxy tab that I would like to connect to the internet through usb modem via the wifi, so is there also a way to share that internet connection with the other computers on the network? Thanks in advance.....
