  • How do I reinstall/enable snapper?

    - by Aaron Digulla
    I had errors in my root filesystem (btrfs) so I recreated it from a backup but now, snapper doesn't work anymore: # /usr/bin/snapper -v -v -v -v create --description test IO Error. # snapper -v delete-config Deleting config failed (deleting snapshot failed). # snapper create-config / Creating config failed (subvolume already covered). # snapper -c root create-config / Creating config failed (subvolume already covered). # snapper list Type | # | Pre # | Date | User | Cleanup | Description | Userdata -------+---+-------+------+------+---------+-------------+--------- single | 0 | | | root | | current | I also tries to reinstall/remove and install the package snapper but without any luck. Any ideas how I can make snapper work again? openSUSE 12.3 with kernel 3.7.10-1.1-desktop.

  • Pinning Google Chrome's "Application Shortcuts" to the Windows 7 Taskbar

    - by Humphrey
    I love the idea behind Google Chromes Application Shortcuts, but they don't integrate well for me into the Windows 7 taskbar. Ideally, I'd like to be able to have my most used webpages (gmail, calendar, etc) as separate windows, pinned to the Windows 7 taskbar. I've created some application shortcuts on my desktop, but I've come across the following problems. If I open my gmail application shortcut, and then later on open a normal chrome window the new window will also use the gmail icon in the taskbar, even if that window has nothing to do with gmail. (What's weirder, is that this new window then uses a high-res gmail icon, but my actually application shortcut window uses a low-res icon. If I pin the application shortcut to the taskbar, then the icon turns into the regular chrome icon. Any idea's how to fix these issues? Or are they bugs in google chrome? Chrome version: 4.0.249.89

  • Different keyboard layouts at same time for different devices

    - by Joao Carlos
    I have a MacBook Pro running Snow Leopard, and I am using it as a portable but also desktop computer. In order to acheive this, I bought a VGA adapter and I am using it with an external mouse, keyboard, and monitor. The problem is, the external keyboard layout is different from the one on the macbook. It is set to US qwerty (its a logitech G15), and because of that, most keys behave differently than they should. Question is, how can I set up different layouts at same time for different devices? I want US for external keyboard and PT for the default one.

  • What is the best file system and allocation size for a USB flash drive?

    - by e-t172
    I'm considering using my 4 GB Kingston DataTraveler USB stick to store my Firefox and Thunderbird profiles for my laptop and desktop PCs. I want to maximize performance when using Firefox. The question is: what is the best file system and allocation size for the fastest Firefox profile operation on a USB flash drive? I'm using Windows 7 on both machines and I don't care about compatibility or the drive's lifetime. I just want to maximize performance. I could even use ext2 with the Ext2 IFS driver if that means it'll be faster. I'm assuming (perhaps I'm wrong) that putting a Firefox profile on a USB stick would be a "lots of small files" usage. In that case, it seems that NTFS would perform best, but I'm not sure. Besides I found nothing regarding the best allocation size to use. Considering that the default allocation size is designed for hard drives (which have different characteristics), I'm assuming that the default allocation size is not the best.

  • Make windows vista file explorer act normally

    - by user25866
    Is there some file I can remove or something I can do to globally ensure that windows visa/xp/etc doesn't do annoying things? Annoying things: 1) Hide the file extension 2) All these "meta" columns I could care less about in "details" view (rating, album, date taken, Assistant's name, Artist, 35mm focal length, City, Other City, etc...). All I want are Name, size, date created, date modified, and file extension. MAYBE file chmod settings. 3) That garbage in the left pane known as "favorite links." (Documents, desktop, photos, music, etc...) 4) Switching between detail view, large icon view, thumbnail view, list view, and tiles when I goto differnt folders, all I want is detail view, with the same columns every time. That's it. I shouldn't have to get third party software to make my file system browseable, but if I need to so be it... Why are all these settings buried away? It feels like I have to apply them onto each folder every time.

  • Command-line way to send keystrokes to a window open on a different X-session

    - by Sanjay Manohar
    I have a Ubuntu desktop open and logged on, on my main machine. I am then also logging in to this machine from a remote computer, using X2go which creates a new X-session. I have a libreoffice file open on the original session. I want to save this file and close it - but from the remote machine! (Both sessions have same user logged in; I can sudo if needed) I have tried using xdotool search but this fails to find the window. Is there a way to do what I want from this second session? I can see the process with ps -A I can even see the open file with lsof! How can I do a "save-and-close" on it?

  • Windows 7 x64 Pro not indexing PDF content ?

    - by Wookai
    In an attemp to get rid of all the paper clutter that I receive each day, I started scanning and ORCing all my important documents last year. I was using Windows Desktop Search on Vista to index my "Administrative" folder in which I keep all these scanned documents, to be able to quickly retreive them when needed. I upgraded to Windows 7 RTM recently (I got the x64 Pro version, via the MSDN-AA channel of my university). Since then, it seems that the content of the PDFs is not indexed anymore. For example, I have the warranty for my GTX260 graphic card. In the PDF, using Acrobat Reader, I can search for the string "GTX260" and it finds the relevant lines. However, if I perform the same search in the folder containing the PDF, nothing is found. I checked in the indexing options, the folder is supposed to be indexed.

  • How to determine why a burned DVD won't boot?

    - by cat pants
    So I have an interesting problem where a burned DVD of "debian-7.2.0-ia64-CD-1.iso" won't boot. The DVD is a DVD+RW. I have tried erasing, burning, and booting from "debian-live-7.0.0-i386-gnome-desktop+nonfree.iso" and that works fine, but I would rather install debian 7.2 with the x86-64 architecture. After burning "debian-7.2.0-ia64-CD-1.sio", I can mount the CD as well and it appears that all the files show up correctly. I was just wondering if there is any sort of boot sector I can try inspecting on the ISO to see if perhaps it is incorrect. Thanks!

  • How to switch users without entering password

    - by torbengb
    I'm a newbie running Ubuntu 9.10. I have two users (wife and me), and each user's screensaver is set to lock so that on wakeup, we get to choose which user's desktop to go to. However, Ubuntu requires a password, so this is pretty tedious. I'd like to switch users without entering any password. I know about this trick that works for the boot login, but it doesn't deal with multiple users. Is it possible to set empty passwords for users in Ubuntu, or skip the password in other ways? (I'm expecting real Linux users to suggest that passwordless users must not get any rights and there be an admin user with a strong password. Yes, you're right. But that's not what this question is about. Thanks.)

  • How to diagnose repeated freezing of windows 7 (comes back alive in few seconds)

    - by Akash Kava
    I installed Windows 7 in a 3 year old machine, it installed successfully, took all drivers and running great, but what happens is every 5-6 minutes it freezes for few seconds... 30 seconds to 1 minute and then comes back alive. I checked Event Viewer, nothing matching the frozen timeline. I would appriciate any help on how to detect causing service/hardware. After it comes alive, everything runs normal, I did run task manager and checked cpu usage, at time it freezes just before and after that no task took more cpu or memory, it was like idle machine. No external usb drives or no devices, on board intel desktop board with SATA HDD, SATA hdd running in absolute good mode.

  • How Ubuntu cloud version enforces the "no root login" over ssh ?

    - by Maxim Veksler
    Hello, I'm looking to tweak ubuntu cloud version default setup where is denies root login. Attempting to connect to such machine yields: maxim@maxim-desktop:~/workspace/integration/deployengine$ ssh [email protected] The authenticity of host 'ec2-204-236-252-95.compute-1.amazonaws.com (204.236.252.95)' can't be established.

  • RAID10 without write-back cache = horrible write performance?

    - by Harry Mexican
    I have just provisioned a dedicated server on singlehop. I'm running it through some tests to know what to expect performance-wise. On the I/O side (with 4 1TB disks in RAID 10) I get: write-cache disabled 200 MB/s read throughput 30 MB/s write throughput I thought that was really low compared to my desktop HD which gets 150-150 or so. So I had a chat with them and they suggested enabling the write cache. New results: write-cache enabled 280 MB/s read 260 MB/s write which is great and all but means I'd have to add a BBU for an additional monthly cost. Is it normal for the write throughput to be 1/4 of a regular drive on RAID10, if you don't have write cache? It almost feels like its intentionally bad to force you to pony up for the BBU. I'd be happy with normal non-raid performance of 150/150.

  • Can't install Parallels Tools on Debian 7.2.0

    - by jfm429
    (Parallels Desktop 9, latest version) As per instructions, I switch to root: $ su - root $ whoami root $ echo $EUID 0 and then execute the installer: $ cd /media/cdrom0 $ ./install and I get this error: sudo: unable to execute ./install: Permission denied What? I'm root! What's with this? I double check to make sure the execute bit is set: $ ls -lA | grep install$ -r-xr-xr-x 1 root root 17284 Oct 25 09:22 install Yep. People online are saying that you need to drag the install script to the terminal after typing sudo. So I do that, and this command is what's formed: $ sudo '/media/cdrom0/install' sudo: unable to execute /media/cdrom0/install: Permission denied What's the solution here?

  • X11 Forwarding works on Windows with Xming and Putty, but not with ssh command line

    - by seaders
    I have a micro Amazon instance the I want to use for testing and everything is going fine until the title. If I set up all the info in PuTTy, open it up and run 'xclock', all runs perfectly and it opens on Xming on my local desktop. If, however, I run ssh xxxxxxx.amazonaws.com xclock I get Error: Can't open display: If I run either of ssh xxxxxxx.amazonaws.com -X DISPLAY=localhost:0:0 xclock ssh xxxxxxx.amazonaws.com -Y DISPLAY=localhost:0:0 xclock I get the same again, but just after about a 30 second delay. In .ssh/config in Windows, I do have ForwardX11 yes set, and I really can't think of anything more to get this working. The fact that PuTTy is working perfectly, not no matter what I do on the command line, I get absolutely no joy is driving me crazy. Can I even see the commands PuTTy is running somewhere, to see if it's doing some extra magic? The ssh I'm running in Windows is MinGW32's.

  • Mouse clicks stop working sometimes

    - by AlbertoPL
    I am having a serious issue with my mouse in which it will randomly not be able to click or cause other problems. Here is the breakdown: Sometimes, I can no longer left-click on many of my windows/taskbar (in order to focus them). Even though I can still left click on my desktop icons or the currently active window, I cannot focus any of the others. Other times, when I have a browser open, I will hit to go back one page and it will automatically go forward one page. I know it's a mouse issue because this behavior stops when I unplug the mouse. Things will be fine when I plug the mouse back in, but eventually the behavior starts up again. My mouse is a Razer Diamondback 3G and I am running Windows 7 Professional 32 bit. Any ideas?

  • How can I register a custom protocol with xdg ?

    - by julien
    I've been struggling this morning trying to associate an application with a custom protocol, namely emacsclient and org-protocol. I'm calling this protocol from a webbrowser bookmarklet, and I get the following behaviour : In chromium, the "Launch Application" dialog comes up, and calls xdg-open org-protocol://... which ends up firing a new chromium frame. In firefox, I've tried setting network.protocol-handler.app.org-protocol to an empty string or my emacsclient path, anyhow I get the following error message : "Firefox doesn't know how to open this address, because the protocol (org-protocol) isn't associated with any program" without even showing any external application selection dialog. I'm not using any desktop environment, so I need to make this work strictly with xdg, however, despite reading the shared mime info spec etc, I still can't fathom a working configuration.

  • Why is systemd not setting my system time?

    - by Alex Chamberlain
    I'm running Arch Linux. Recently, when I turn on my PC, the system time is set to 1:00 1 January 1970 - presumably the 1:00 o'clock is from the timezone shift.

  • Erase all traces of Windows 8

    - by user1032531
    Just bought a new HP pavilion desktop with Windows 8. I wish to totally remove Windows 8 and all data on the hard drive, remove any windows partitions, delete all data, and then install a fresh Linux. Problem is I can seem to get to boot from USB or boot from CD. It appears that Windows 8 added the following two "features": UEFI which substitutes what we have known as the BIOS Secure Boot which prevents anything but the installed operating system How do I completely and totally erase all traces of Windows 8? Is it still possible to reformat the hard drive? I don't want a duel boot, I don't want to go back to Windows 7, I just want anything Windows gone.

  • Who moved this PC here aka Locate which port on switch a PC is plugged into

    - by ggonsalv
    The catch is you have no SNMP access, not even public. The end vision is locate a PC in building easily even if PC's are moved around. The MAC address of the PC is known and the software would run as client on each desktop, reporting back which port the PC was plugged into. Well from a programmer perspective, my network skills are not the best. Yes I could use SNMP, download the MAC port table, load it into SQL, match it to the PC name. Seems alot of work. Lets say I ping a single point from the PC. Would the echo have some thing unique for each device on the same switch? All I need to identify some thing unique for each PC plugged into each port. If the PC was moved from location A to a different location then the unique response would change.

  • Linux Live CD cannot play video

    - by lamwaiman1988
    I want to switch from windows to linux, but before the switch I would like to try them out in the Live CD. I downloaded the iso and created a multiboot usb stick ( by YUMI Multiboot USB Creator ). I can boot into Ubuntu Desktop 12.04 64 bit LTS and Linux Mint 13 Mate 64 bit. I can access the hard drive from there and I tried some video with the default player comes with them ( e.g: GNOME Player and VLC Player ). The player opened but the video didn't play. However, I can play the same video in Puppy Linux. ( Puppy Linux doesn't has a choice over 32-bit or 64-bit ) Maybe my CPU didn't support 64 bit? Here is a snap from CPUZ: CPU: AMD Phenom II X3 710

  • How to Install PCRE Development Headers on Mac OSX

    - by martincarlin87
    I just upgraded my MacBook Pro to Mavericks and my local Ruby on Rails development environment isn't running straight off the bat, when I visit localhost I see It works! and remembered I needed to start Phusion Passenger, so when I run passenger start it checks all the requisites and fails when it gets to the PCRE Development Headers: * Checking for PCRE development headers... Found: no It tells me to go to http://www.pcre.org/ to download them so I downloaded 8.33 from here which went to my Downloads folder, so I unzipped it, cd'd to the folder and ran: ./configure make make install Then cd'd back to my rails app directory on my Desktop and re-ran passenger start but it's still the same. Tried a new Terminal window but that didn't make any difference. I must have done this before to get my dev environment working but can't seem to solve it this time. I also tried brew install pcre but it says Warning: pcre-8.33 already installed.

  • How can I stop my laptop display from flickering when I connect my TV?

    - by Lord Torgamus
    I have a laptop with an HDMI output port running Vista, and an HDTV with HDMI input ports. The laptop is set to extend its desktop onto a second monitor. When I connect the computer to the TV with an HDMI cable, my laptop screen usually flickers rapidly. Most of the time it lasts for about 30 seconds, but sometimes it lasts for several minutes and once in a while it doesn't happen at all. It wouldn't be so bad except that the cursor moves back to the center of the laptop screen with each flicker, so I can't really do anything until the machine decides it's ready to calm down. I haven't been able to find any pattern at all for the causes or duration of the flickering. It doesn't seem to matter what programs the laptop is running when I connect it to the TV, whether I enable the extended display before or after I connect the TV or which HDMI port/cable I use. What could be causing this, and how can I make it go away?
