  • Ubuntu 14.04 is unstable on my Thinkpad T61

    - by user292386
    I have this super old Thinkpad T61 and installed Ubuntu 14.04 on it. I noticed X11 is quite unstable. It'd freeze all the time, especially after suspension. Sometimes dash would appear as a blue screen, etc, etc. I have tried Xunbuntu as well. It's pretty much the same. But I don't seem to have problem with Debian 7.5. I still prefer Ubuntu to Debian. I just wonder which build of Ubuntu would have similar video/X versions as Debian 7.5. Thanks.

  • ubuntu 12.04 cannot login

    - by Kikky Bikky
    I am using Ubuntu 12.04. I cannot login. I get to the grub menu and go root, delete my /home/user/.Xauthority file and change my password. I move /home/user/.profile to /home/user/profile, reboot, and I can login (this is fixed by moving .profile to some other name). But if I am idle and Ubuntu displays the screensaver, I cannot login. I have pressed Ctrl+Alt+F1 and removed /home/user/.Xauthority. I check the existence of /home/user/.profile and it does not exist. There is no way for me to login to X from the keyboard connected to the box. I can ssh -CXY to the ubuntu box and login without any problem. Can someone help me fix this problem?

  • Dual booting Windows 7 and Ubuntu 12.10 on UEFI laptop

    - by fccoelho
    I have a notebook pre-installed with Windows7 and I installed Ubuntu 12.10 on it following the standard installation steps in the installation image. The only problem is that on reboot the machine continues to boot Windows ignoring the presence of Ubuntu (Grub never comes up). My partition scheme is this sda1: NTFS 612MB sda2: NTFS 50GB (after resizing during Ubuntu installation. This is the main windows partition) sda4: extended sda5: ext4 /boot sda6: btrfs / I have tried Boot-repair and it didn't help. Tried rEFInd boot manager but it doesn't support NTFS partitions. I don't know what else to try. My next attempt is to try to install GRUB by hand to the MBR. Any other Ideas?

  • echo difference between ubuntu and RedHat

    - by arcomber
    I have mostly been experimenting with ubuntu but recently was using a Red Hat Enterprise system and was surprised at a difference I found setting and displaying env variables. In ubuntu I might have an interaction like this: acomber@mail:~$ export MY_VAR=i686-linux acomber@mail:~$ echo $MY_VAR i686-linux acomber@mail:~$ echo "$MY_VAR" i686-linux But on RHEL: acomber@mail:~$ export MY_VAR=i686-linux acomber@mail:~$ echo $MY_VAR acomber@mail:~$ echo "$MY_VAR" i686-linux I know this is a ubuntu forum but why the difference? Why do I need to enclose in quotes on RH? There are no spaces in the variable name?

  • What file format/database format does Picasa use?

    - by Raymond
    I am trying to figure out what file format the .db file and .pmp files are. I tried using db_dump (Berkeley DB) for the .db files, but it seems that they are not Berkeley DB, or of an older version. I have no idea what the .PMP files are.

  • How do I install OpenStack on a single Ubuntu 12.04 node?

    - by Sam Edwards
    I'm having trouble installing OpenStack in Ubuntu 12.04, for various reasons: The official Ubuntu website recommends Juju and MAAS. However, this is a single node I am trying to get OpenStack installed on, and MAAS requires "two or more nodes" according to the docs. Additionally, I don't have any experience in MAAS and Juju and would rather stick to technologies I am more familiar with so that I can debug problems that arise. I have tried StackGeek but this fails because the node only has a single Ethernet port. The node does, however, have the second hard drive required for the nova storage. I have tried DevStack but cannot log into the dashboard. The login form appears fine, but as soon as I try to submit the page, my browser begins loading indefinitely. I have tried installing straight from packages, but I get an Internal Server Error in the dashboard upon trying to log in, with no helpful logs anywhere in sight to aid me in debugging the issue. Each of these attempts was with a fresh Ubuntu 12.04 LTS setup; I'm finding it really strange that no matter what I try, I cannot get OpenStack installed. Is this even a stable/mature project? Why am I encountering so many bugs?

  • robocopy transfer file and not folder

    - by Bill McKay
    I'm trying to use robocopy to tranfer a single file from one location to another but robocopy seems to think I'm always specifying a folder. Here is an example: robocopy "c:\transfer_this.txt" "z:\transferred.txt" But I get this error instead: 2009/08/11 15:21:57 ERROR 123 (0x0000007B) Accessing Source Directory c:\transfer_this.txt\ (note the '\' at the end of transfer_this.txt) But if I treat it like an entire folder: robocopy "c:\folder" "z:\folder" It works but then I have to transfer everything in the folder. How can I only transfer a single file with robocopy?

  • Digital Asset Management, iPhoto / Aperture server... alternative

    - by Sisyphus
    Afternoon, Clients, 10 : All Apples running either Leopard or Snow Leopard Server : Snow Leopard server, (and I have a old Dell Poweredge 650 at home running Gentoo 2.6, if anybody as a Linux solution). The situation: I work in small design company with 8 people, at present we are looking to consolidate all our image files onto one location, at present we each use our preferred single user DAM solution, be it, Adobe Bridge, iPhoto/Aperture (some don't bother at all) The filetypes commonly used are .psd, .pdf, .eps, .tiff, .jpg and RAW image files. Ideally what is needed: Centralised on one server, but allows us to search via spotlight (not essential, but would be nice) Include searchable metadata information such as date, location, title Open-source or as low cost as possibly Allow simultaneous users to import files So far, I have looked at a few open source DAM, systems, such as Razuna, Gallery (not strictly DAM), ResourceSpace, Notre-DAM, while these are brilliant and open-source, they don't integrate as smoothly with the Desktop as iPhoto and aperture. For iPhoto and aperture, I have tried creating a Shared library on the server (a tad laggy), and also using a drive with no permissions, put a library and letting each client read from it, however if they want to put images onto the library only, it's only supports one user at a time writing to the library... Any ideas what could fulfill our needs? Or is it time to bite the bullet for FinalCut Server? Thanks in advance.

  • Why is mkfs overwriting the LUKS encryption header on LVM on RAID partitions on Ubuntu 12.04?

    - by Starchy
    I'm trying to setup a couple of LUKS-encrypted partitions to be mounted after boot-time on a new Ubuntu server which was installed with LVM on top of software RAID. After running cryptsetup luksFormat, the LUKS header is clearly visible on the volume. After running any flavor of mkfs, the header is overwritten (which does not happen on other systems that were setup without LVM), and cryptsetup will no longer recognize the device as a LUKS device. # cryptsetup -y --cipher aes-cbc-essiv:sha256 --key-size 256 luksFormat /dev/dm-1 WARNING! ======== This will overwrite data on /dev/dm-1 irrevocably.

  • How do I troubleshoot a segfault in Ubuntu that occurs when typing a bogus command?

    - by Alan
    We've got a production server running Ubuntu 11.10. We're encountering segfaults that appear under various conditions. The simplest reproducible case is when we login to an ssh session as our administrative user and enter a bogus command. You'd expect the standard "command not found" error message. Instead, we get a segfault in python. The user's default shell is /bin/bash. For example: $ asdf Segmentation fault Info from /var/log/syslog: Jul 6 15:39:20 PROD001 kernel: [2155960.605695] python[7873]: segfault at 0 ip (null) sp 00007fffd030b808 error 14 in python2.7[400000+233000] Some details about the server: $ uname -a Linux PROD001 3.0.0-16-server #29-Ubuntu SMP Tue Feb 14 13:08:12 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux $ cat /etc/issue Ubuntu 11.10 \n \l Before we ask the IT department to reinstall the O.S., I'd like to understand what got us here. The system and/or this particular user's environment is suspect. Many people have touched this server over the past year, so I'm wondering if it is missing libraries, incorrectly installed packages, etc. I'm hoping that if we can understand what's going wrong in this case, it will help explain why we're getting segfaults in a couple of other scenarios. Any tips on troubleshooting this segfault will be appreciated!

  • Free-as-in-beer binary file format inspector

    - by fbrereto
    I am looking for a utility that gives me the ability to specify a binary file format and then interpret a file of bytes according to that format. (Something along the lines of the 010 Editor, but infinitely more cost-effective). Something that runs on Mac OS X would be preferred, but I'm interested to see what all is out there in general (while more of a hassle I'd be willing to run a tool on Windows if it were superior.) What's your preference?

  • Which Ubuntu-like Linux OSs work well on a flash drive?

    - by Evan Kroske
    I want a Linux OS that I can load on a flash drive, but I don't want to relearn an entire operating system. I want to know which tiny Linux installations are most like Ubuntu. For example, I'd like to use the apt-get package manager, the Gedit text editor, and the bash shell. I'd like to use something that's already popular, stable, and highly compatible, but it needs to fit comfortably in one gig of my four-gig flash drive (just the essentials; I'll use the remaining three gigs to store installed programs and files). I have no preference for window managers; I just want something small and fast that works like Ubuntu. What is the most popular Ubuntu-like OS that can be easily run on a thumb drive? Edit: I'm not sure I understand how this works. I don't to use a USB drive as a LiveCD; I want to plug in a USB stick and use the computer as if it was my own. In other words, I want to be able to install programs on the drive on one computer and use them on another. Do any of these OSs let me do that? Please forgive my ignorance.

  • Utility to unmap a network drive when the screen saver starts

    - by JimR
    I'm looking for a way to unmap network drives when the screen saver turns on. I have a few users that share an external, encrypted drive (Samba share, not windows) and they have a requirement to disconnect the drive mapping when the local machine is idle. I'd also like it to warn them if there are open files on the mapped drive, if possible. There is also a requirement to force the password to be reentered before mapping when the machine comes back from idle. Is there a Windows setting or utility out there in the wild that meets these requirements?

  • How can I open a file whose name starts with "-"?

    - by PJ
    I am running Ubuntu, and would like to open a file whose file name starts with "-"(minus). When I try to open the file with pico or vim, the command thinks that the "-" sign is an option for the command. I tried enclosing the file name with quotes ('), but I still get the same error. I tried with bash and zsh, but still the same error.

  • Dual-booting Ubuntu and Pardus with GRUB2...Pardus no show?

    - by Ibn Ali al-Turki
    Hello all, I have Ubuntu 10.10 installed and used to dual-boot Fedora, but I replaced Fedora with Pardus. After the install, I went into ubuntu, and did a sudo update-grub. It detected my Pardus 2011 install there. When I rebooted, it did not show up in my grub2 menu however. I went back to Ubuntu and did it again...then checked the grub.cfg, and it is not there. I have read that Pardus uses a grub legacy. How can I get Pardus into my grub2 menu? Thanks! sudo fdisk -l Disk /dev/sda: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xd9b3496e Device Boot Start End Blocks Id System /dev/sda1 * 1 15197 122067968 83 Linux /dev/sda2 36394 60802 196059757 5 Extended /dev/sda3 15197 30394 122067968 83 Linux /dev/sda5 36394 59434 185075308 7 HPFS/NTFS /dev/sda6 59434 60802 10983424 82 Linux swap / Solaris Partition table entries are not in disk order and update-grub Found linux image: /boot/vmlinuz-2.6.35-25-generic Found initrd image: /boot/initrd.img-2.6.35-25-generic Found memtest86+ image: /boot/memtest86+.bin Found Pardus 2011 (2011) on /dev/sda3 Yet after this, I go to grub.cfg, and Pardus is not there.

  • Ubuntu Wubi "drive" failure; mount drive in XP?

    - by 618034
    Hi there, I installed the Wubi distribution of Ubuntu on a separate partition (which is silly, since why do I care if Windows can still manage the partition?) a few months back; it was pretty awesome, until Linux hosed. At this point, I can get Ubuntu to boot if I try really hard through grub, but once it does start, the screen is hosed, so no dice. At this point, I'd like to wipe it all and start over, but I need to get some stuff off the "disk". The Wubi install makes this difficult, since the "disk" is a flat file on an NTFS partition. I've done just about everything I can think of — I renamed the virtual disk .iso, mounted it with VirtualCloneDrive, then used whatever magic EXT3 (EXT4?) readers I could dig up on the Internet to parse the mount — but nothing's working. Can you offer any suggestions? The "disk" is currently in D:\ubuntu\disks\root.iso. Many thanks! (I may be high-latency at the moment, apologies if I don't address follow-ups quickly)

  • What OS would you use for a simple fileserver and why?

    - by barfoon
    Hey everyone, Im looking to set up a simple fileserver: 5 - 7 clients - Mixed Windows, Linux, Mac OSX - connecting over wireless and wired Serving ~200GB content - Photos, MP3's, ISO's etc What OS would you recommend for this fileserver? I understand XP limits the number of when connecting to different shares so this probably isnt the best choice. Any recommendations are appreciated. Thank you,
