  • Ubuntu 12.04 Frequent Kernel Panics

    - by Jordan Johns
    Dealing with what seems to be quantum behavior here. I'm having frequent Kernel panics and the problem is very hard to locate. To cut to the chase of what is going on I am essentially getting this screen: This occurs always after login (login screen is fine, can go into my TTY's and everything). But once I log in I have anywhere from 0 (instant) to 10 seconds before everything grinds to a halt and freezes. The only way I found out that it was a kernel panic was going into a TTY while it happens. At first, I figured something must be wrong with memory. Ran memtest86, full standard test. No errors. OK. CPU problem? Windows works fine, ran prime95 and a bunch of other torture tests for many hours. Drive problem? Nope. fsck reports no problems and the smart status is ok. Overclocking problem? Nope. Windows is working fine, and I also reset the bios to prove the point it was not the cause. At a loss here, even trying to reinstall the thing it gives me the same problem even attempting to install ubuntu (like right after you try to select "install ubuntu" or "try ubuntu first before installing"). Anyone have any thoughts? Its very bizarre, its as if my system hates linux and is trying to tell me not to use it (that would be a terrible reality). Thanks!

  • Use hotplug and turn on/off PCI device for replacing NIC

    - by Ryota Hashimoto
    How can I turn off the PCI slots and change the device (especially NIC) without shutting the server down? I found a similar question (How do I turn off PCI devices?) but there are no /sys/bus/pci/slot and no files in /sys/bus/pci/slots. I'm using 12.04 LTS. $ uname -a Linux d1-c1-r1-p1 3.2.0-38-generic #61-Ubuntu SMP Tue Feb 19 12:18:21 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux $ lspci | grep Eth 04:00.0 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01) 04:00.1 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01) 09:00.0 Ethernet controller: Intel Corporation 82599EB 10-Gigabit SFI/SFP+ Network Connection (rev 01) 09:00.1 Ethernet controller: Intel Corporation 82599EB 10-Gigabit SFI/SFP+ Network Connection (rev 01) $ ls /sys/bus/pci/ devices/ drivers_probe slots/ drivers/ rescan uevent drivers_autoprobe resource_alignment $ ls /sys/bus/pci/devices/0000\:04\:00.0/ broken_parity_status driver modalias rescan subsystem class enable msi_bus reset subsystem_device config firmware_node net resource subsystem_vendor consistent_dma_mask_bits irq numa_node resource0 uevent device local_cpulist power resource2 vendor dma_mask_bits local_cpus remove resource3

  • Loud fans despite cool system under Linux (but not Windows)

    - by Sman789
    My new desktop computer runs almost silently under Windows, but the fans seem to run on a constantly high setting under Linux. Psensor shows that the GPU (with NVidia drivers) is thirty-something degrees and the CPU is about the same, so it's not just down to Linux somehow being more processor-intensive. I've read that the BIOS controls the fans under Linux, which makes sense given the high fan speeds when in BIOS as well. It's under Windows, when the ASUS AI Suite 3 software seems to take control, that the system runs more quietly and only speeds the fans up when required. So is there a Linux app which offers a similar dynamic control of the fans, or a setting hidden somewhere in the ASUS BIOS which allows the same but regardless of the OS? EDIT - I've tried using lm-sensors and fancontrol, but pwmconfig tells me "There are no pwm-capable sensor modules installed". This is after the sensors-detect command does find an 'Intel digital thermal sensor', and despite the sensors working fine in apps like psensor. Help getting this to work would likely solve the problem.

  • Mounting NFS directory causes creating Zero byte files

    - by Alaa
    I have two Servers, Server X (IP 192.168.1.1) and Server Y (IP 192.168.1.2), both of them are ubuntu 9.1 i have created varnish load balancer on them for my drupal website (pressflow 6.22) I have mounted a directory of imagecache from server X to Y as below @X:/etc/exports == /var/www/proj/htdocs/sites/default/files/images 192.168.1.2(rw,async,no_subtree_check) @Y:/etc/fstab == 192.168.1.1:/var/www/proj/htdocs/sites/default/files/images var/www/proj/htdocs/sites/default/files/images nfs defaults 0 0 also i made this on server X X:/var/www/proj/htdocs/sites/default/files$ chmod -R 777 images i tried to touch, rm, vim, and cat files in images directory that has been mounted on Y and everything went fine. now, ALWAYS when server Y's imagecache tries to create an image in images directory, the image is created with ZERO byte file size. anyone face the same before? any idea of how to fix this problem or what might cause it? Thanks for your help

  • Ubuntu application keeps disappearing

    - by Ibrahim
    This issue is something entirely different and perhaps one of the reason I switched from Fedora to Ubuntu 6 months back when 12.04 was launched. While applications like thunderbird or Firefox is running, it simply keeps disappearing without popping up any error. It was just exactly the same thing happened in fedora only when i UPGRADED to the latest version from earlier one and the same thing I guess is haunting me in Ubuntu only after upgrading i

  • Why does my .desktop file execute via double click but not from the menu?

    - by Insperatus
    I've installed FTL: Faster Than Light on my girlfriend's Lubuntu machine and created a .desktop file for it. Strangely, the program won't launch via its menu entry under 'Games'. If I navigate to /home/andi/.local/share/applications/ via pcmanfm and double click on FTL Faster Than Light.desktop the game launches without a problem. I know the menu entry is generated through the .desktop file so why won't it launch from the menu? Here's the .desktop file I created: FTL Faster Than Light.desktop

  • Changing default application

    - by ragebunny
    Hey i have recently installed Sublime text 2 and i must say it's one of the best text editors i've ever used or even seen in use. So i managed to install everything and added to the unity menu and also change all the entries of gedit.desktop to sublime.desktop and it works just fine for most files but i realised that some files still open in gedit, for example php files, i checked the default list for php but there isn't anything in there. So how would i set the default for opening php files? Update:Also Sublime doesn't show up in them properties menu where i can usually select the default program. Thanks for the help. I'm using 12.10.

  • Can I use electricsheep with gnome-screensaver?

    - by Joshua Robison
    I installed electricsheep and xscreensaver, started everything up and was amazed and mesmerized for several minutes staring into the beautiful fractile universe, When all the sudden I moved my mouse and was HORRIFIED by a noisy hideous monster?!?! no anti aliasing , ugly white box!!! horribly pixelization IN MY FACE I'm referring to the disgusting xscreensaver unlock box, that seemingly several users have been trying to theme... But I don't want to theme it. I want my Beautiful Ubuntu unlock screen! My thoughts are that if I could use electricsheep with the gnome-screensaver then that would fix my problem. Any takers?

  • How do I give proper attribution when distributing my modified Ambiance theme?

    - by WarriorIng64
    I made a modified version of 12.04's Ambiance that uses a dark sidebar for Nautilus, and I would like to redistribute it via e.g. gnome-look.org. From the Launchpad page for the light-themes package, it says the themes are available under a Creative Commons BY-SA 3.0 license. The way I understand it, I can distribute my modified theme so long as I provide proper attribution for it and place it under the same license. In this case, who do I attribute as the author of the original theme and where/how should I display this attribution?

  • Free space in tmpfs partition not adding up

    - by Dean Herbert
    I have had my /tmp/ partition filling up recently when it should not be anywhere near full. On further investigation, I found that the partition was listing free space a lot lower than it should be. I am guessing a remount will fix this, but am very curious as to why this has happened and where this space has gone. du output: root@odoroki:/tmp# du --summarize -h 3.3M . df output: root@odoroki:/tmp# df -h /tmp Filesystem Size Used Avail Use% Mounted on tmpfs 3.9G 3.3G 653M 84% /tmp Update: after deleting some files it has happened again. du output: root@odoroki:/tmp# du -h --summarize 11M . df output: root@odoroki:/tmp# df -h /tmp Filesystem Size Used Avail Use% Mounted on tmpfs 3.9G 3.9G 0 100% /tmp I have a feeling this has started since a recent apt-get upgrade, but it still seems like strange behaviour. I did do a quick scan over lsof output and couldn't see any open/stuck file handles. Unfortunately due to the seriousness of the issue I had to reboot the server, after which usage seems to match correctly.

  • How to disable OSD notifications for specific email addresses?

    - by Zuul
    I receive several logs per day via email, either from testing operations, server status or backup resumes. Can I some how disable the notification balloon either by a specific email address, the email subject or any other possible filter, as to not be constantly notified about the success operations? I've looked within the Notify OSD Configuration, but couldn't find any option to this end. Since the email comes with different information when errors occur, I already have filters within Thunderbird as to move error logs to a folder that I keep tabs on... If relevant, I'm using Ubuntu 12.04 fully updated, and Thunderbird 15.0.1.

  • Ubuntu 12.04 Faster boot, Hibernate & other questions

    - by Samarth Shukla
    I've recently started exploring Ubuntu (my 1st distro). I fresh installed precise without a swap (4GB ram). The only issues are, slow boot (regardless of the swap) and instability after a few days of installation. The runtime performance is immaculate otherwise. Even though not needed, I still set swappiness = 10. I've tried the quiet splash profile to GRUB; already have preload installed. But it still is pretty slow. I am not too confident on recompiling the kernel yet. But you could please advice me on that too. I've also added the following to fstab: #Move /tmp to RAM: tmpfs /tmp tmpfs defaults,noexec,nosuid 0 0 (Also if you could please tell me the exact implication/scope of this tweak on physical ram & the swap.) But nothing has happened really. So what alternatives are there to make it boot faster? Also, right after fresh install, though no swap partition, the system still showed /dev/zram0 of arond 2GB which was never used (probably because of the above fstab edit). Finally, I experimented with Hibernate a little, but many claim that it doesn't work on 12.04. (Not to mention, I made a swap file of 4GB for it). What I did was: sudo gedit /var/lib/polkit-1/localauthority/50-local.d/hibernate.pkla Then I added the following lines, saved the file, and closed the text editor: [Re-enable Hibernate] Identity=unix-user:* Action=org.freedesktop.upower.hibernate ResultActive=yes I also edited the upower policy for hibernate: gksudo gedit /usr/share/polkit-1/actions/org.freedesktop.upower.policy I added these lines: < allow_inactive >no< /allow_inactive > < allow_active >yes< /allow_active > But it did not work. So is there an alternate method perhaps that can make it work on 12.04?

  • Ubuntu 12.10 over Ubuntu 11.10 seems to hang

    - by Angela Trapp
    My installation of Ubuntu 12.10 over Ubuntu 11.10 seems to hang on "saving installed packages". How long should I wait before knowing for sure that something is wrong? I stopped it once and tried re-installing but am getting the same results. I'm installing from a USB stick. I'm connected to the internet using a wired connection but I'm reading here to connect to a wi-fi network while installing. Could this possibly be the issue? I can't install using wi-fi at the moment as my router was fried in a brownout yesterday. I've ordered another router online so as soon as it gets in, I'll try again. Any suggestions are appreciated! Please let me know if you need more information. It's a 32-bit installation and I have 1 GB of memory. Thanks!

  • How to diagnose Ubuntu CPU spikes / IO wait?

    - by Jeff Welling
    I'm using Ubuntu and every couple minutes it goes unresponsive for a half second to a full second, which isn't normally a problem but makes trying to code extremely frustrating when your trying to hit backspace or navigate the code and nothing is happening. The problem is, the freezes are so brief that top doesn't have time to show me what is spiking the CPU (assuming something is, but I don't know what else could cause this). Does anyone know how to troubleshoot this performance issue? Edit: I've tried login in with Gnome Classic (No Effects) instead of Unity but it still freezes up every once in awhile. Edit: The CPU graph doesn't seem to be showing any actual spikes so it seems you were right and my original diagnosis of CPU spikes being the problem was incorrect, I now suspect IO wait. I don't recall this happening for the brief few weeks I had Windows 7 Starter running on it though, which leads me to believe it isn't (just?) the hardware.. is there anything I can tweak to improve this? I'm using an Acer Aspire One D257, with Ubuntu 11.10. Edit: Output of dmesg is at http://paste.ubuntu.com/1060054/ and kern.log is at http://paste.ubuntu.com/1060055/

  • Remove panel shadow in KDE 4.8+

    - by Meho R.
    It seems that panel shadow is somehow hardcoded in KDE 4 and devs do not have any plans to change it and/or make it customizable. So, what I'm actually asking is some kind of hack (if there is any) which will remove the shadow of the panel in KDE 4.x completely (but without need to disable all desktop effects in the process). Possible application: When a user wants a completely transparent panel, no top/bottom borders at all, the shadow is completely out of place and destroys the experience.

  • A program/CLI command to help translate multiple file names

    - by cipricus
    I have hundreds of files with different names that I want to translate into a different language. Is there an application/CLI action that would allow me to copy all this names as in a list/table and then, after having translated them, to paste them back into the list/table, or that would allow a procedure somewhat similar to "Rename" in Thunar but with a more complex action closer to what I have described? (I am in Lubuntu and I prefer not to use Nautilus due to unwanted interference with LXDE/pcmanfm desktop and LXPanel. If there is a solution in Nautilus please provide it but try to give an alternative if possible.)

  • dbus signal for volume up & down

    - by jldupont
    I recently upgrade to Ubuntu 10.10 Maverick Meerkat and to my dismay, the mediakeys "volume up" and "volume down" do not send Dbus signals anymore... how can I add these back? Thanks!! Update: it seems that under some circumstances (which I don't know exactly yet), the DBus signals start working again. It is as though when a certain application (TBD) is executed, the dbus signals are re-activated.

  • Why is Evince not displaying application fonts/text for me?

    - by Philippe Fenderson
    Any time I use Evince, it just shows boxes where all the text should be. Instead, it uses the box symbol which I know stands for not being able to find a character. This problem occurs on every menu, and makes it impossible to tell what's going on in any part of the application. I've tried Googling for this problem, but my -fu is weak or it's hard to search for. I'm pretty tech-literate, and I'm running a fairly stock 10.10 install with GNOME.

  • Ubuntu App Contest - Open Source Libraries

    - by Chao
    I just found out about and started looking into the Ubuntu App Contest, and I wanted to double check the contest's stance on using open source libraries built by others that are freely available on the web. I read through the rules and some of the other Q&As, and it sounds like using these libraries would not be allowed (since it could mean the app isn't built from scratch, and the library would not be in the Ubuntu archive - although I could bundle the library with the app), and I just wanted to verify this assumption. Thanks! Chao
