• Mouse stopped responding after installing Ubuntu Server

  - by Danijar

  It was 2 operating systems on my machine, Windows 7 and Ubuntu Desktop 12.04, both 64bit version. All works well, firstly I installed Win, then the Desktop version of Ubuntu, lasts's GRUB rewrites windows's boot and of course added it as a variant to load. Yesterday I wish to play with Ubuntu Server 12.04, and install it as a third operating system. During the installation Server's GRUB seems to rewrite that which installed earlier (background color became black, was purple). Firstly, newly installed GRUB generates me overmuch load options for Ubuntu Desktop, by two for each kernel version (normal and recovery modes). OK, it's bearable, but most thing, that the mouse on this machine is totally stops responding, regardless which operating system I choose to load. Hope somebody help me. Thanks in advance!

• Compiz using 40% CPU on Ubuntu 13.10

  - by Olli

  After upgrading to 13.10, compiz process has started taking up to 40% of CPU resources. In addition, Unity is sluggish just like in this recent question Compiz at 30% of CPU on Thinkpad T420. My PC is HP Compaq NX6310 and Compiz version is 0.9.10.2. First I had error message during boot, but did find solution for that (Bug #1014289) by updating the kernel to newer 3.11.4, it did not change the CPU usage. For the CPU problem I tried solution for Bug #1221837 by adding the line MESA_GL_VERSION_OVERRIDE=1.4 in the file /etc/environment - that did not help me, so my problem seems not to be the same bug. Any suggestions on how to resolve this issue?

• How do I fix this half screen problem?

  - by link1275

  I just installed 12.04, and my entire screen is being displayed entirely on the top half of my screen. The bottom half is always black or some technical garbage from the boot up. To interact with the bottom half of the screen I have to move the mouse over the screen to pull part of the bottom half of the screen on top and vice-versa. Does anyone know how to fix this? Also my computer told me, at startup, to go to here: http://wireless.kernel.org/en/users/Drivers/b43#devicefirmware.

• Unwittingly activate wrong wireless driver and now cannot activate the correct one

  - by Sumeth Chaochuti

  I just installed Kubuntu 10.10 on my MacBook 3,1 and found no wireless connection. Using KPackageKit I activated Broadcom b43 because it had already been selected for me. When I subsequently tried to activate Broadcom STA, however, I was returned with an error. After reading Jockey log I removed the wrong driver and reinstalled all drivers so that I can activate the correct one. It hasn't work even though KPackageKit now shows that I have installed: bcmwl-kernel-source bcmwl-modaliases broadcom-sta-common broadcom-sta-source According to the log it appears as if there are conflicts but I don't know how to rectify it. I'm completely new to the platform, just started using Kubuntu 2 days ago. I'll appreciate any advice anyone can give. Thanks.

• Dell Vostro 1510 can't connect to wireless--how can I fix this?

  - by Miss Spider

  I'm having some trouble with my Dell Vostro 1510. I installed wubi on it two days ago and I've only been able to use the Internet with an ethernet cable. The network seems to definitely recognize that the wireless--even other peoples' wireless--is there, but it can't manage to get on. I'll post the lpsci here, so that you can see the Broadcom card I'm working with. I have downloaded the kernel 2.6.39-0-generic, which doesn't appear to have done a lick of work. 06:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01)

• BCM4313 Wireless on Ubuntu Server 12.04

  - by KJ Tsanaktsidis

  I'm trying to run an old netbook with Broadcom BCM4313 wireless as a print server with Ubuntu Server 12.04. Setting up the wireless without the GUI, however, is proving problematic. I do think however I've narrowed down the problem. I've tried both the wl driver (from bcmwl-kernel-source) as well as the (included) brcmsmac driver. With both of them, when I issue the command iwlist wlan0 scanning (eth1 for wl), I only see neighbouring networks- not my own. I believe this might be because my networks are n-only, but my neighbouring networks are mixed mode (I suspect this because the output of iwlist wlan0 scanning shows "Bit Rates" only as high as 54 Mb/s). Any ideas how to go about getting this thing to connect?

• Wireless issues BCM4311

  - by user207757

  I have been working with a nice Gent but I am getting stuck. I am just getting back in to Linux and Ubuntu was recommended. I like the look so far but the wireless isn't working I run the update and when it says complete it hangs at the end. Please let me know what to do at this point. "wl: Running module version sanity check. - Original module - No original module exists within this kernel - Installation - Installing to /lib/modules/3.11.0-12-generic/updates/dkms/ depmod.... DKMS: install completed." Hangs here!! Thanks for all your help, D.C.

• How do I get a Line6 UX1 soundcard to work?

  - by the_drow

  I own a Line6 UX1 soundcard and I would like to make it work for Ubuntu. I have followed the instructions here and it worked. But at some point I upgraded my kernel version (not sure what uname -a prints but it's related) and it stopped working. Here's what uname -a prints: Linux ubuntu 2.6.32-29-generic #58-Ubuntu SMP Fri Feb 11 20:52:10 UTC 2011 x86_64 GNU/Linux I figured out that maybe it's installed per version so I used svn update and hit make again. My guess was right as it copied the relevant files to the new version's folder. I restarted and still nothing. Should I revert to an older version? Or is there a solution here?

• Linux : un patch de 60 lignes règle les problèmes d'alimentation du noyau, son auteur est ingénieur chez RedHat

  Un patch de 60 lignes règle les problèmes d'alimentation du noyau de Linux Son auteur est ingénieur chez RedHat Depuis quelques temps (depuis la version 2.6.36 du noyau pour être précis), les critiques se faisaient de plus en plus nombreuses de la part des utilisateurs de Linux contre la consommation électrique de plus en plus importante du kernel de l'OS. Que la communauté se rassure, ce désagrément devrait être rapidement (et certains diront : enfin) réglé grâce à un patch dont les premiers détails ont été publiés début novembre. Ce correctif ne compte qu'une soixantaine de lignes de code mais il devrait pouvoir définitivement régler les problèmes de régression li...

• Turned off my computer and o it's opened up in grub. How do I tell it to boot into lubuntu?

  - by Magpie

  It's just a commandline. I have tried my usual trick of sticking a usb with lubuntu in there to see if I can boot from my usb but I get a boot error (I normally wouldn't using that usb). GNU grub version 2.00-7ubuntu11 also just using basic things I know I hits ls then tried boot hd0 but it says: you need to load the kernel first I have no idea how to do this. I looked at the commands and most of them hve obscure names that are not helpful. UPDATE: I hit exit and that allowed be to boot from usb. Hopefully I will be able to find what I need to install to get it booting normally again from there.

• Dell Inspiron N5110 Battery lasts only for 1.5 hours as opposed to 4 hours on Windows 7

  - by ubuntufan

  I've a Dell Inspiron N5110 laptop with the following specs: i5 processor 4 GB RAM NVIDIA GeForce GT540M Ubuntu 12.04LTS My laptop is overheating and the battery is lasting for only about 1.5 hours. I had checked if the battery indicator was problematic but it turned out it wasn't. I drained the battery to it's least possible value and that came to around 1 hr 40 minutes. In fact, I've the same problem with Debian and Xubuntu as well. I would like to get some proper solution for this. FYI: I've been having this problem since Ubuntu 11.04 but I'm not able to solve this in spite of trying various fixes like reducing brightness, Removing startup apps, Updating kernel and what not?. I'm a big fan of Ubuntu but this problem is stopping me from using Ubuntu and I'm using Win7 for 90% of the time.

• Can turning off drm_kms_helper polling affect screen brightness control?

  - by dodecaphonic

  I have a Samsung R430 notebook that has been running Ubuntu for close to a year, now. Since I've upgrated to Maverick, I've been dealing with little, but increasingly annoying issues, that put my faith to question. The first one, a CPU-intensive set of drm_kms_helper, made me compile my own kernel and set polling to off just so I could move my mouse without frequent stuttering. That led me to dealing with a screen that gets dimmer and dimmer after each sleep/wake-up cycle, which eventually leads me to reboot. Since I have seen some KMS and brightness related bugs around, I was wondering if it is a definite cause for my problem. If so, has there been any advance on the excessive polling issue for those of us plagued by it?

• Cannot make NVIDIA driver work with Ubuntu 12.10

  - by user1293231

  I seem to have a problem similar to many but I didn't manage to get it solved: have a Lenovo N581 with an NVIDIA GeForce 610M have just installed a fresh Ubuntu 12.10 64 bits, + KDE and am trying to have my NVIDIA card work. Have tried all workarounds posted: purge nvidia, install kernel source/headers and then reinstall nvidia-current-updates (or just nvidia-current), do "sudo nvidia-xconfig". It does create a xorg.conf but does not much (no Module Section by the way). The result is that my system (jokey) tells me that the driver is there but not in use and I only get a 640x480 resolution. If I try to launch nvidia-settings it does indeed tell me that the nvidia driver is not used. I do all this under kde but I guess it does matter at this stage. Any hint of how to resolve this? I feel stuck and cannot use any of the acceleration which is partly why I got that laptop in the first place... thanks for any help/advise you may provide!

• Constant noise in speakers and headphones

  - by user103978

  On my laptop, Samsung 300V5A-S19 I have the constant noise from the speakers. If I wear headphones, the sound becomes more pronounced (at half volume it mutes the music). The noise level is independent of the volume control. The noise disappears only when volume is completely muted. For the record, the sound is reminiscent of the noise of the waves or something like that. System information: Ubuntu 12.10, kernel 3.5.0-18 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 04) All packages in the system updated.

• Screen tearing (very noticable during video playback) with HD3000 AND HD Radeon 6630m

  - by NilRecurring

  I did not have this issue with Ubuntu 11.10. Well, to be clear, I did, but it was easily remedied with compiz workarounds. I have tried both the propriety and open source ati drivers, and the intel HD 3000 (as far as I know) should be part of the Kernel already. So I am pretty much 100% stumped given my general lack of Linux knowledge. I really enjoy this OS, would hate to have to return to Windows (read: HATE) because of something as trivial as video playback. Some details: Lenovo Thinkpad Edge e520 Intel HD 3000/AMD HD Radeon 6630m Ubuntu 12.04 64bit.

• Get and install Nvidia GeForce 8400 GS driver

  - by williepabon

  Recently, I changed my OS kernel from 10.04 to 11.10 (bugs), but after doing it, the video driver for the 8400 GS disappeared (was there in 10.04). I worked out the same procedure I did to install it in 10.04, mainly, sudo apt-get --purge remove nvidia-current sudo apt-get --purge autoremove sudo add-apt-repository ppa:ubuntu-x-swat/x-updates sudo apt-get update sudo apt-get -y install nvidia-current but it didn't work even though the commands seemed to install the driver without problems.

• Linux 3.6 sort en version stable : veille hybride, TCP Fast Open, VFIO, améliorations de Btrfs et suppression du cache IPv4

  Linux 3.6 sort en version stable ajout de la veille hybride, TCP Fast Open, VFIO, améliorations de Btrfs et suppression du cache IPv4 Linus Torvalds vient d'annoncer la sortie de la version 3.6 stable du Kernel Linux. La nouveauté phare de cette mouture est l'introduction d'un mode de veille hybride, longtemps supporté par Windows et Mac OS X. L'option Suspend to Both (Veille et hibernation combinée) permet de suspendre l'activité de l'ordinateur tout en conservant le contenu de la mémoire vive sur le disque dur (uspend-to-disk) et ensuite une sauvegarde du système dans la mémoire (suspend-to-RAM). Le grand avantage de ces deux techniques liées est qu'elles permettent le retou...

• Second click on a launcher icon with more than one window open doesn't do a scale of that application

  - by Eastsun

  In unity, if I click an icon in the launcher with multiple windows open it doesn't show me all open windows for that application. However, this works in unity2d. I known there have a same question asked before: here! But I think my condition is not as same as the previous question. ubuntu 12.04 64-bit unity 5.16.0 kernel linux 3.2.0-33-generic gnome 3.4.2 Edit I just find a interest thing: There are four workspace, label it as A, B, C, D. If I firstly open two windows of firefox in A, as I mentioned above, second click on the firefox icon does nothing. But after I open a window of firefox in B, the second click on the firefox icon in workspace A magically works!! And then, I open two terminal in workspace C, second click doesnot work until I open another terminal window in D. So, it seems that the second click only work if the application be opened more than one workspace.

• System update and now no wireless connection in Ubuntu 10.04

  - by Alphaeuphemia

  I'm running an older version of Ubuntu (10.04), and updated yesterday through the update manager. The system informed me I needed to restart, so I did, then immediately shut down the system and went to work. When I rebooted later in the evening, I couldn't connect to my wireless router. I could find my connection and had the passcode and all that usual business, but could this be a kernel or driver issue caused by the update? If so, how can I fix it? I've attempted to go through the troubleshooter, but to no avail. Additionally, I put off upgrading to the next stage of Ubuntu for so long that I can no longer prompt the system to ask me if I'd like to. Any way to change this?

• What sort of things can cause a whole system to appear to hang for 100s-1000s of milliseconds?

  - by Ogapo

  I am working on a Windows game and while rendering, some computers will experience intermittent pauses ("hitches" for lack of a better term). When profiled they appear in seemingly random places in the code. Eventually I noticed that it wasn't just my process that was affected, but (seemingly) every process on the system. All of the threads in my application hitch at once. The CPU utilization drops during these hitches and it appears as if most processes make no progress. This leads me to believe this may be an Operating System or Driver issue, but it only occurs while playing the game (and only on some systems). What sort of operations might the operating system be doing that would require the kernel to pause all user threads and block. Some kind of I/O? At first I thought of paging but my impression is that would only affect a single process, no? Some systems in use: Windows, DirectX (3d), nVidia cards (unknown if replicates on ATI), using overlapped io for streaming
