  • Cinnamon is broken after upgrade to 13.10

    - by user2306488
    I see reports of people with Unity broken after upgrading to 13.10. In my case Unity works fine but cinnamon is broken. It opens the startup applications but no window manager, no menus and the keyboad shortcuts won't work. As a consequence I can't even log out or shut down cleanly. The logs say: Oct 19 10:32:42 Aveline colord: Profile added: icc-1727cc5030c477b20ad75593e757248d Oct 19 10:32:43 Aveline gnome-session[9157]: WARNING: App 'cinnamon.desktop' exited with code 1 Oct 19 10:32:43 Aveline gnome-session[9157]: WARNING: App 'cinnamon.desktop' respawning too quickly Oct 19 10:32:43 Aveline gnome-session[9157]: CRITICAL: We failed, but the fail whale is dead.

  • Unable to start VMWare Workstation after upgrade to 13.04

    - by pst007x
    After upgrading to 13.04 I am unable to start VMWorkstation. I get the following message: Before you can run VMware, several modules must be compiled and loaded into the running kernel. Kernel Headers 3.8.0-19-generic Kernel headers for version 3.8.0-19-generic were not found. If you have installed them in a non-default path you can specify the path below. Does anyone have any idea what to do next? Ubuntu 13.04 64bit If I direct the path to: /usr/src/linux-headers-3.8.0-19-generic I get the following message: C header files matching your running kernel were not found.

  • How do I fix my ethernet card losing network connection every few minutes with kernels 3.8.x?

    - by igoryonya
    I'm using Ubuntu 13.04. My laptop is Acer Aspire one 722-c58rr, and my ethernet card works for a few seconds at a time with kernels 3.8.x, however, kernels 3.5.x and below worked fine. On kernels 3.8.x, it works fine after boot for about a minute, then it looses network connection. When pinging to some address, it says: network address is unreachable, but it can ping it's own address. The address is statically configured. Everything was working fine before. I went to vacation, where I used WiFi and 3G connections, so I didn't notice that the problem occurred. Came back home, plugged in into the ethernet. It worked for a minute then stopped. Rebooting commutator fixed the problem. Tried to connect to a different commutator, same problem. Unplugging and plugging the cable fixes the problem for another minute. Disconnecting eth in Network manager and reconnecting it again, does the same thing. WiFi has no such problem. Tried to use a different cable that works fine on another computer, the same problem. Tried to boot with the lower kernel version, the same problem was happening until I got to the version 3.5 of the kernel series. Everything works fine on the kernel 3.5.x, but I don't want to miss out on the new kernel's features. Executing commands, when booted with 3.8 kernel series, give the following results: lspci| grep -i eth: 06:00.0 Ethernet controller: Qualcomm Atheros AR8152 v2.0 Fast Ethernet (rev c1) dmesg| grep eth1: [ 89.548291] atl1c 0000:06:00.0: atl1c: eth1 NIC Link is Up How do I fix it, while staying in the new kernel version?

  • Unable to install ZFS (Ubuntu 13.10)

    - by user209707
    I'm fairly new to Ubuntu and wanted to setup a server running ZFS/XBMC - The XBMC install went fine, however I ran into trouble getting ZFS working. Configuration : Ubuntu 13.10 (GNU/Linux 3.12.0-rc7+ x86_64) I attempted to install ZFS native using : sudo add-apt-repository ppa:zfs-native/stable sudo apt-get update sudo apt-get install ubuntu-zfs This failed to install due to "Module build for the currently running kernel was skipped since the kernel source for this kernel does not seem to be installed." Trying sudo modprobe zfs shows FATAL error : module not found. Here, they mentioned it was to do with lacking build dependences- I followed the answer which was to run sudo apt-get remove --purge ubuntu-zfs zfs-dkms zfsutils spl spl-dkms libzfs1 dkms Then, REBOOT. Then, do: sudo apt-get install linux-headers-generic build-essentia sudo apt-get install ubuntu-zfs " This leaves me in the same situation with "Building only for 3.12.0-rc7+ Module build for the currently running kernel was skipped since the kernel source for this kernel does not seem to be installed." when trying to install ubuntu-zfs. Trying sudo apt-get install --reinstall zfs-dkms also does not work.

  • Is it important to reboot Linux after a kernel update?

    - by lfaraone
    I have a few production Fedora and Debian webservers that host our sites as well as user shell accounts (used for git vcs work, some screen+irssi sessions, etc). Occasionally a new kernel update will come down the pipeline in yum/apt-get, and I was wondering if most of the fixes are severe enough to warrant a reboot, or if I can apply the fixes sans reboot. Our main development server currently has 213 days of uptime, and I wasn't sure if it was insecure to run such an older kernel.

  • conflicting info about the running kernel version in FreeBSD

    - by John
    I asked a related question about uname before, now want to ask from another angle because the following simple yet obvious conflicting outputs may mean there is something many people did not think of (me included). I'm running FreeBSD 9 RELEASE, please see the following commands: # sysctl kern.bootfile kern.bootfile: /boot/kernel/kernel # strings /boot/kernel/kernel |grep RELEASE|grep 9 @(#)FreeBSD 9.2-RELEASE-p7 #0: Tue Jun 3 11:05:13 UTC 2014 FreeBSD 9.2-RELEASE-p7 #0: Tue Jun 3 11:05:13 UTC 2014 9.2-RELEASE-p7 The above kernel file suggests the running kernel is 9.2-RELEASE-p7. But... # dmesg Copyright (c) 1992-2012 The FreeBSD Project. Copyright (c) 1979, 1980, 1983, 1986, 1988, 1989, 1991, 1992, 1993, 1994 The Regents of the University of California. All rights reserved. FreeBSD is a registered trademark of The FreeBSD Foundation. FreeBSD 9.1-RELEASE #0 r243825: Tue Dec 4 09:23:10 UTC 2012 ... # uname -a FreeBSD localhost.localdomain 9.1-RELEASE FreeBSD 9.1-RELEASE #0 r243825: Tue Dec 4 09:23:10 UTC 2012 [email protected]:/usr/obj/usr/src/sys/GENERIC amd64 So dmesg and uname says it's 9.1-RELEASE. I also did an extensive find / -type f -exec grep -l "9.1-RELEASE" {} \; but found no possible kernel file that contains 9.1-RELEASE. What could lead to the above conflict, and what kernel I am actually running? Please note I run RELEASE and ran freebsd-update to do binary update, so no compiled kernel is involved. And I have rebooted multiple times after freebsd-update. And the system is not in jail etc, just the only system on that computer.

  • GRUB2 panic: "No such partition"

    - by Android Eve
    I managed to install 10.04 on a system that already has 8.04 (separate partitions, of course). It also installed GRUB2 onto the MBR. After discovering that there is no menu.lst anymore, I edited /etc/grub.d/40_custom to point to where my other OS partitions are: menuentry "Ubuntu 8.04" { set root=(hd0,0) linux /boot/vmlinuz-2.6.24-28-generic initrd /boot/initrd.img-2.6.24-28-generic } menuentry "Windows 7 Ultimate 64-bit" { set root=(hd0,2) chainloader (hd0,2)+1 } GRUB2 displays the menu with those entries but when I select any of them, it refuses to load them, saying "No such partition". I know the partitions are there, as 10.04's "Disk Utility" sees them without any problem. How do I get GRUB2 to recognize them?

  • is ksplice production ready?

    - by faultyserver
    I would be interested to hear the serverfault community's experiences with Ksplice in production. Quick blurb from wikipedia: Ksplice is a free and open source extension of the Linux kernel which allows system administrators to apply security patches to a running kernel without having to reboot the operating system. and Ksplice can, without restarting the kernel, apply any source code patch that only needs to modify the kernel code. Unlike other hot update systems, Ksplice takes as input only a unified diff and the original kernel source code, and it updates the running kernel correctly, with no further human assistance required. Additionally, taking advantage of Ksplice does not require any preparation before the system is originally booted (the running kernel does not need to have been specially compiled, for example). In order to generate an update, Ksplice must determine what code within the kernel has been changed by the source code patch. So a few questions: How has the stability been? any odd issues that you have encountered with its 'rebootless live patching' of the kernel? Kernel panics or horror stories? I have been running it on a few test systems and so far its been working as advertised, but I am interested in what other sysadmins experiences have been with Ksplice before going 'all in' and deploying this on our production servers. So, anybody using Kspice in production? update: hmm, not seeing any real activity on this question after a couple of hours (besides some kind upvotes and favs). Maybe to spark some activity I'll also ask a few more questions and see if we can get this discussion going... "If you are aware of Ksplice, is there a reason you are not using it?" "Do you feel its still too bleeding edge, unproven or untested?" "Does Ksplice not fit well within your current patch-management system?" "Do you hate having systems that have long (and secure) uptimes?" ;-)

  • Mouse scroll issue after kernel build

    - by Anish S Kumar
    I have a Intel Cedar Trail netbook. For graphics to work, i had to build kernel 3.1 with the drivers. I followed the steps in this document After doing that, now my graphics is fine, but my mouse scroll does not work. Is that because I have not build the kernel properly? Have i missed selecting some options in the kernel compile menu? It will be nice if someone can help me. Also my wacom bamboo tablet is not recognized, i have installed the xserver-xorg-input-wacom drivers.

  • Linux : le kernel 2.6.34 est stable, il introduit deux nouveaux systèmes de fichiers pour remplacer

    Mise à jour du 18/05/10 Le kernel 2.6.34 disponible en version stable Il introduit deux nouveaux systèmes de fichiers pour remplacer le ext4 et gérer la mémoire Flash Le kernel 2.6.34 est à présent disponible en version stable. Trois mois après la précédente version majeure du noyau (cf ci-avant), ce nouveau kernel propose deux nouveaux systèmes de gestion de fichiers. Le premier est issu du projet Ceph et sépare les données des méta-données. Ce système de fichier distribué peut faire penser à Lustre d'Oracle (utilisé par exemple dans les supercalculateurs). Même si Ceph, toujours assez expérimental, n'est pas aussi per...

  • Boot-up hangs unless I manually select the kernel in the bootloader

    - by The Photon
    In my stock Ubuntu install (forgot which critter its named for, about one year old), I am able to boot up normally only if I manually select the kernel in the bootloader (Grub). If I step away and it boots from the default, the system will hang with the word "Ubuntu" on a graphics screen and a few white/red blinking dots beneath it. umb@digdug:~$ uname -a Linux digdug 2.6.32-42-generic #95-Ubuntu SMP Wed Jul 25 15:57:54 UTC 2012 i686 GNU/Linux Synaptics says I have 'grub-pc' version 1.98-1ubuntu-13 installed. My grub.cfg does have default="0" which I would expect to make the default be the first kernel shown in the selection screen. The system is a laptop with an i7 processor, and I have had trouble with some kernels not being able to boot at all in the past, and power management is not working perfectly, but I have not had problems booting the latest kernel (2.6.32-42) if I select it manually in Grub. Any idea what is going on here and how can I fix it so that I can re-boot unattended?

  • Macbook Pro - Randomly sleeps and won't wake up

    - by James
    All, I have a Macbook Pro 13" (mid 2009) that has had a long time issues which seems to be getting worse. Occasionally, I will go to wake the computer with the keyboard and can't wake it. The HDD spins up, the light on the front of the computer stops blinking, but as soon as it seems like the display should light up, the HDD stops and the light begins blinking again. More rarely, the computer will suddenly sleep while I am using it and then enters the same sleep loop. The only way to resume working on the computer is to wait. Doing a hard restart just puts it right back into the 'sleep loop.' Here is an excerpt from kernel.log showing the laptops apparent narcolepsy: Jun 5 22:20:40 james-hales-macbook-pro kernel[0]: Wake reason: OHC1 Jun 5 22:20:40 james-hales-macbook-pro kernel[0]: Previous Sleep Cause: 5 Jun 5 22:20:40 james-hales-macbook-pro kernel[0]: The USB device Apple Internal Keyboard / Trackpad (Port 6 of Hub at 0x4000000) may have caused a wake by issuing a remote wakeup (2) Jun 5 22:20:40 james-hales-macbook-pro kernel[0]: HID tickle 31 ms Jun 5 22:20:41 james-hales-macbook-pro kernel[0]: 00000000 00000020 NVEthernet::setLinkStatus - not Active Jun 5 22:20:45 james-hales-macbook-pro kernel[0]: MacAuthEvent en1 Auth result for: 20:4e:7f:48:c0:ef MAC AUTH succeeded Jun 5 22:20:45 james-hales-macbook-pro kernel[0]: wlEvent: en1 en1 Link UP Jun 5 22:20:45 james-hales-macbook-pro kernel[0]: AirPort: Link Up on en1 Jun 5 22:20:45 james-hales-macbook-pro kernel[0]: en1: BSSID changed to 20:4e:7f:48:c0:ef Jun 5 22:20:46 james-hales-macbook-pro kernel[0]: AirPort: RSN handshake complete on en1 Jun 5 22:20:48 james-hales-macbook-pro kernel[0]: 00000000 00000020 NVEthernet::setLinkStatus - not Active Jun 5 22:20:54 james-hales-macbook-pro kernel[0]: Jun 5 22:20:55 james-hales-macbook-pro kernel[0]: Wake reason: OHC1 Jun 5 22:20:55 james-hales-macbook-pro kernel[0]: Previous Sleep Cause: 5 Jun 5 22:20:55 james-hales-macbook-pro kernel[0]: The USB device Apple Internal Keyboard / Trackpad (Port 6 of Hub at 0x4000000) may have caused a wake by issuing a remote wakeup (2) Jun 5 22:20:55 james-hales-macbook-pro kernel[0]: wlEvent: en1 en1 Link DOWN Jun 5 22:20:55 james-hales-macbook-pro kernel[0]: AirPort: Link Down on en1.

  • OOM-Killer, jboss and kernel panic

    - by user32425
    Hi, We are running RedHat 3.4.6(x32) on VMWareEsx3.5(x64) with 6GB RAM. A few java processes(including jboss) are running in the background. The problem is that the java processes consume lots of memory, and sometimes they are killed by the OOM-killer. When OOM-killer is about to act, the free physical memory is very low 100MB-200MB, but the swap is not used (99% free). Sometimes this causes a kernel panic too. So why isn't the swap used? How to investigate this kernel panic? Is using 6GB memory on 32bit Redhat wise? Thanks

  • Compiling the Linux kernel, how much size is needed?

    - by ant2009
    I have downloaded the newest most stable Linux kernel, 2.6.33.2. I thought I would test this using VirtualBox. So I create a dynamically sized harddisk of 4 GB. And installed CentOS 5.3 with just the minimum packages. I setup the make menuconfig with just the default settings. After that I ran make and got the following error: net/bluetooth/hci_sysfs.o: final close failed: No space left on device make[2]: *** [net/bluetooth/hci_sysfs.o] Error 1 make[1]: *** [net/bluetooth] Error 2 make: *** [net] Error 2 The amount of space I have left is: # df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup00-LogVol00 3.3G 3.3G 0 100% / /dev/hda1 99M 12M 82M 13% /boot tmpfs 125M 0 125M 0% /dev/shm My virtual size is 4 GB, but the actual size is 3.5 GB. $ ls -hl total 7.5G -rw-------. 1 root root 3.5G 2010-04-13 14:08 LFS.vdi How much size should I give when compiling and installing a Linux kernel? Are there any guidelines to follow when doing this? This is my first time, so just experimenting with this.
