[SOLVED] Question About SSD Alignment (Do I Have to Reinstall?)

I purchased a Crucial M4 (256GB) and I put a lot of work into this install, it's set up really nice. But I came across the Arch Wiki and SSD alignment. I don't really understand what the article says, but I did add the noatime and discard flags as it suggested. What I don't understand in particular is if I have to wipe and reinstall Arch in order to use gdisk to align my partitions. I'd rather not reinstall if I don't have to.

  • Question about ICloud. Do I have to back-up my iPad and iPhone4 b4 sync with iTunes?

    Question about ICloud. Do I have to back-up my iPad and iPhone4 to iCloud b4 sync with iTunes? Last time I synced iphone4 with iTunes, I updated to 5.0.1 when I connected, but it wiped my calendar entries. I had to reset to the last date I had synced (4months ago). So my question is... Now that I have iCloud, should I back up both my iPhone and my iPad before I sync with iTunes?  And will all the data from iPad, iPhone, and computer all merge when the iPad and iPhone are synced?

    It does not matter.

  • [SOLVED] Question about CPU temperature

    Hi everybody,
    I just want to ask a question about "standard" CPU temperatures because my laptop (a Dell Vostro 3700) is permanently hot with the fans on even when I am not doing anything special.
    I have CPU freq scaling active with the conservative governor, and I use Gnome Shell 3.2 with an nVidia using the nouveau driver.
    Here are "stable" temperatures while writing this post:
    # sensors
    acpitz-virtual-0
    Adapter: Virtual device
    temp1: +72.5°C (crit = +103.0°C)
    nouveau-pci-0100

    Core 2: +73.0°C (high = +95.0°C, crit = +105.0°C)
    And this is the output of mpstat

    The fan, of course, is full speed (very annoying)
    I think that these temperatures are quite high, but I don't know what's really causing all this heating because my laptop is basically idle.
    Any suggestion?

  • [SOLVED] Question about resolv.conf

    I successfully configured my Arch box with a static IP by following the instructions on the Arch wiki page here but had a couple of questions about configuring /etc/resolv.conf:
    1) What is the proper way to obtain the domain name that should be inserted into resolv.conf?
    2) What exactly is this domain name used for?  I read the man page but still don't really understand it.  Why do I need a domain name if I already have a working set of nameservers to resolve IP addresses?
    EDIT: @ewaller Yes I edited the OP because I realized that my original problem was that I just hadn't added a domain name in my resolv.conf file.  I edited my original post because 1) the instructions are already posted clearly on Arch Wiki so my post really wouldn't be beneficial and 2) so I could ask my real question without making other people waste their time reading through my other nonsense

    Yes, I know how to get a nameserver, but I'm asking about the domain name that goes in resolv.conf.  The Arch wiki tutorial for setting up static IP uses the following resolv.conf as an example:
    nameserver 61.23.173.5
    nameserver 61.95.849.8
    search example.com
    My question has to do with what the "search example.com" does.  I don't have a domain name associated with my machine, but if I remove that line, then I get "web page unavailable" when I try to load any web site, which suggests that I'm not connecting to any nameservers right?

  • [SOLVED] Question about GCC error messages.

    I'm currently taking a course in C programming, and I have  a question about the error messages returned by GCC.

    Woah. That is very strange. I've never seen that before.
    I assume you're using Arch Linux. What text editor did you use to write the code? Which terminal application are you using?
    ...those questions are probably unrelated to the problem, but we might as well get them out of the way.

  • [SOLVED] Question About Downgrading to a Spinning Drive from SSD

    I currently have a laptop with an SSD and Arch Linux, and it's aligned specifically for SSD and configured as such. I ordered a brand new laptop, and decided that I will move the SSD from my current laptop to my new one, and put a spinning drive in my current laptop. I was thinking about using Clonezilla to clone my current Arch install on my current laptop SSD to a spinning drive (since I can't afford another SSD right now). However, since my current laptop installation is aligned for an SSD, will that cause problems if I clone it to a spinning drive? My spare spinning hard drives were made before the 4k transition, I believe. I would be putting it on an older 500GB Seagate. I'd rather not start over with a new configuration if I don't have to.

  • [Solved] Questions about Arch on T420s

    Hello everybody,
    I'm relatively new to Arch and switched from Ubuntu last year. Since then I've learned a lot about Linux in general due to the great documentation provided by the Arch community.
    I've managed to install Arch on my Thinkpad T420s with an UEFI Setup using Archboot. But still there are open questions.
    My first question is about the UEFI System partition and grub2. Should the UEFI partition be mounted to the filesystem? What about updating Grub2 (eg for setting boot parameters) when the UEFI System partition is not mounted to the filesystem. Up to now I've set boot parameters by manually mounting the UEFI partition and editing the Grub2's menu.lst equivalent. I think this is not optimal.
    My second question is about some graphical artifacts in Gnome 3. The T420s uses Intel HD 3000 Graphics. Sometimes icons in nautilus disapear or get replaced by black planes when hovering over them with the mouse cursor. Similar black planes replacing icons can be observed sometimes in Evolution or Rhythmbox. Furthermore gnome-terminal becomes transparent sometimes when I'm scrolling or switching between powertop2 tabs. Anyone else observed similar issues on their T420s or on other models with an Intel HD 3000? I use several options for the i915 driver but none of them seem to be related to the graphical artifacts. Furthermore I've disabled dVT in the BIOS.
    options i915 modeset=1
    options i915 i915_enable_rc6=1
    options i915 i915_enable_fbc=1
    options i915 lvds_downclock=1
    options i915 semaphores=1
    My last question is about the USB ports on my T420s. I've 3 USB ports, one on the left side (USB2.0) and two (USB3.0 and another USB2.0) on the back side. When I plug in a HD on the left side everything works fine and the filesystem is automatically mounted. When I plug in the same HD on the ports of the back side the HD isn't even recognized. Interestingly when i boot with the HD plugged into the back side ports everything works fine. Can you point me any directions how to solve this problem?
    Hopefully sombody using Arch on a T420s has already solved these issues and could share the solutions. Otherwise I would be grateful for any suggestions.
    Sincerely yours,
    Tobsen
    Last edited by tobsen (2012-02-09 17:15:27)

    Hi Tobsen, I have a T420 also. Perhaps my experiences will be some help?
    Regarding the USB ports: I installed Arch on my T420 with the Kernal 3.0.3 snapshot and all the USB ports worked out of the box. That sounds like a problem with udev to me, though. Have you checked the wiki article on this?
    Regarding the graphical artifacts: For me, when a popup window appears from hovering the mouse over an icon, the window is sometimes blank grey. It's totally inconsistent, and I can fix it by just hovering over it again, so I haven't really bothered to examine the source of the problem. Could this be related to your problem with the GPU? I figured it was a problem with the windows manager I'm using (Enlightenment e17), which is unstable.
    Regarding UEFI: I don't use GRUB2, so this may not be good advice, but I personally feel like you should avoid auto-mounting partitions you don't always need. It slows down boot, and if the partition is mounted, user error could damage it. I say you should keep doing what you're doing.

  • Question about SSD space? And BootCamp?

    Ok, so I installed BootCamp a while ago because I wanted to have a Windows partition and to play games and such on my MacBook Air (2012). The game I wanted to play is relatively large; about 23 GB + or - a few gigs, and I knew that I should include some extra space in there for updates and other stuff. So, I put about 30GB on the partition. When I went on it, there was only like 10GB free!!! So, I kept increasing and increasing until now, I have a like 48.5 GB partition to hold a 23 GB game with only 7.3 GB free. So:
    1) Where did all of the rest of the storage space go?!
    2) I noticed I think 10 GB or so is in the "Windows" folder. Can I compress this? Will it damage/mess up the Windows Partition? I want to free up some space, but I don't want to break anything.
    3) Can I REMOVE a few gigs from the Windows partition, or do I have to start over? If I start over, will I have to redownload my game and all that?
    Section 2
    I have a 128 GB SSD MacBook Air. I thought that it would be plenty of room. However, I just got a new iPhone, and within a month and a half, I have taken over 2,100 pictures, which takes up numerous GB. So, if I want to back up my iPhone and iPod and all that, I will need a lot of space on my computer. However, I have a Windows partition taking up about 48.5 GB as I remember, so that's about 40% of the entire amount of space on my computer. So, I had a 72 GB portion or so on my Mac side. I thought that this would be enough, but I somehow only have like 28 GB left. If I keep taking pictures, want to back up things, get apps, etc., I would like to free up/add space. So:
    1) I know this sounds stupid (I thought I was good with computers and Apple technology, but I just wanted to make sure) ... but is there any way to permanantly add extra SSD space onto my Mac? Because there's the option to upgrade your Mac to like 256 GB which would be awesome, but as far as I know, this is only online, with the more expensive version of the 13" MacBook Air, and I don't know if you can do this with the computer already bought and installed and all that. So, is there any way to add space? Like not free up space, but ADD it?
    2) How does the whole Time Machine/ Pass port thing work? If I transferred 10 GB of stuff to Passport or whatever, (1st of all, is it a USB?) if I plugged it in to my computer, could I easily transfer stuff back and forth? Would it take a while?
         i) If I had a game on my computer, happened to have Passport or something, and transferred the files to Passport... (this will be a long question) once I plug in the Passport, could I launch the game? Or would I have to transfer the files back to the desktop...
           a) Basically, what I'm getting at is... If I had a game's files on Passport / Time Machine / whatever it is called, if I had it plugged in to my computer, would I have to transfer files to the computer to launch/play a game, or could I just play it by putting in thing..
    3) If there is a way to increase the space to 256 GB or so, how much would this cost? How long would it take?
    I am so sorry about all of my confusing questions, but I just want to ask a bunch at once so I can set things straight in my mind xD
    Please help! Thanks so much!

  • *Solved* Question about ATI Drivers

    Ok, I'm just finished installing, and I know most distro's, ask you to remove the open source drivers, before adding in FGLRX  drivers.  Looking at the wiki, I didn't noticed if this needed to be done, and after going through the install, I rebooted.  It went as planned until kdm went to load.  The screen was unreadable.  I used the cd media to mount root, and removed catalyst, and re-installed the opensource drivers.  All is well atm, so I'm trying to figure out what I missed.  My question atm though is during the FGLRX install, it ask's if you want to removed the opensource drivers due to conflict.  If I hit yes, will pacman it automatically remove the required drivers, or do I need to manually remove the Fx86 drivers on my own?
    I do apologize for not having a /etc/X11/xorg.conf report, as it slipped my mind while fixing everything. I'll try to make a better habbit of getting it made. I did do a aticonig --inital before the reboot, so i know it won't that.
    If I missed anything on the wiki, please let me know, I'll look again at it after dinner.
    Thank you all for  your time in the matter.

    Hi there
    First off, which installation method are you following? (ABS using the AUR package, the unofficial repository or the AMD installer). Depending on which method you use, you'll have (or not) a resolved dependency. For instance, you have to remove both the open source driver and your former xorg.conf file (safer is to back it up) to be able to install Catalyst with the AMD's site installer.
    If you use AUR (with a tool like Yaourt for example) or the repo method, pacman/yaourt should do it for you, but in a lot of cases it doesn't (I switched to Catalyst having my OpenBox session built already, so when I tried to remove the open source driver it complained about all of the apps that I had installed for removing a dependency like libgl or mesa) and you'll have to do a pacman -Rdd xf86-video-ati to make it work
    I'm wondering if you remembered to add the mkinitcpio hook (which is needed to make Catalyst work).
    What I would suggest is to re-read the wiki page for Catalyst, see if your card is still supported by Catalyst, maybe your card needs Catalyst-Legacy...
    Best of Luck with that
    I figured it out, and got it working.  I had a typo adding the module for flgxr driver.  Fixed it and a soft boot later, all is well.  I also deicided to make it so I have to "startx" into my gui, incase this happens again, I won't need the installation media.  Thanks for the input.

    if [[ $line =~ $NOM ]]; then
    echo "$line" >> "$outputfileNOM"
    (( ++countNOM ))
    fi
    #Check if the actual line has the PGP flag
    if [[ $line =~ $PGP ]]; then
    echo "$line" >> "$outputfilePGP"
    (( ++countPGP ))
    fi
    else
    echo "$code is not numeric"
    exit
    fi
    done < "$inputfile"
    echo "COUN NON $countNOM"
    echo "COUN PGP $countPGP"
    else
    echo "FILE: $inputfile does not exist or does not have read permissions"
    echo "FILE: $outputfileNOM does not exist or does not have write permissions"
    echo "FILE: $outputfilePGP does not exist or does not have write permissions"
    fi
    I have some questions:
    I) When I do:
    if [[ -r $inputfile && -w $outputfileNOM && -w $outputfilePGP ]]; then
    else
    echo "FILE: $inputfile does not exist or does not have read permissions"
    echo "FILE: $outputfileNOM does not exist or does not have write permissions"
    echo "FILE: $outputfilePGP does not exist or does not have write permissions"
    fi
    I would like to print the things on the else, accordingly, this is, print the right message. Ex: if "$outputfileNOM" did not have the write permission, just print that error. BUT, I don't want to put a lot of if/else, Ex:
    if [[ -r $inputfile ]]; then
    if [[-w $outputfileNOM ]] then
    else
    For the READ permission, and the other for the WRITE
    Is there a way to do it, without using a nesting approach, and that maintains the readability. 
    II) About the:
    if [[ -r $inputfile && -w $outputfileNOM && -w $outputfilePGP ]]
    is OK if I use the flag "-x" instead of -r or -w. I don;t have a clear definition of what is the meaning of:
    -x FILE
    FILE exists and execute (or search) permission is granted
    III) Notice the ATTENTION label in my code. I notice that there are some possibilities, for ex: having white spaces before, after or before or after. I'm believing in the consistency of the input files, but if they change, it will explode. What could I do in this case? Is there an elegant way to manage it? (exceptions?)
    Thank you very much!
    EDIT: corrected what rockin turtle wrote bellow about the format. Thank you.

    I) Regarding your if statement, you could do something like this:
    estr='FILE: %s does not exist or does not have %s permissions.\n'
    [ -r $inputfile ] || ( printf "$estr" "$inputfile" "read" && exit 1 )
    [ -w $outputfileNOM ] || ( printf "$estr" "$outputfileNOM" "write" && exit 1 )
    [ -w $outputfilePGP ] || ( printf "$estr" "$outputfilePGP" "write" && exit 1 )
    II)The -r/-w/-x mean that the file has the read/write/execute bit set. Do a
    $ man chmod
    for details.
    III) You should be able to do
    if [[ "$line" =~ .*\<NV\> ]]; then
    echo "..."
    (( countNOM++ ))
    fi
    but that didn't work for me when I tried it.  I don't know if this is a bug in bash, or (more likely) something that I am doing wrong.
    Regardless, I would write your script like this:
    #!/bin/bash
    file=$(egrep '^[A-Z]..[0-9]{2}' "$1")
    grep '\<NV\>' <<< "$file" > "$2"
    grep '\<PV\>' <<< "$file" > "$3"
    echo 'Count NON:' $(wc -l < "$2")
    echo 'Count PGP:' $(wc -l < "$3")
    Note: In reading your script, your comments imply that each line of the input file starts with 'llnnn' but the example line you gave starts with 'lllnn'.  That is, there are 3 letters (AVO) followed by 2 numbers (01). The above script assumes that lines start with 'lllnn'

  • [SOLVED]Questions about e17-svn

    I installed e17-svn and e17-extra-svn from commouty repo,it's beautiful...and buggy.It creates several desktop icons for my partitions,i deleted that from Desktop and .e/e/fileman/favorites folder,but they appear again the next time i login.Firefox and thunar freeze many times as well,and the most unacceptable thing is that i can't logout,every time i try logout,the e17 hangs there forever and i have to restart x myself.I use kdm4 as the login manager,and i try slim as well,the problem remain.Anybody knows how to solve those problems?Thanks.

    WTF, Something weird going on here.  It used to be #pacman -S e-cvs and you got a perfectly useable e17 desktop.  I just tried to #pacman -S e17-svn and it says no such package or group so there must be some changes goin' on as a #pacman -S e-cvs gets you nowhere now.  Be patient, though--I say to myself
    I'll bet pressh is on the job!  Hmmm... I don't recall seeing any announcement about a big change in getting enlightenment in arch.  Maybe I missed something?
    Edit:  I guess I did miss something.  Searching the forums brings me this: http://wiki.archlinux.org/index.php/E17 from a post in 2008-07-03 http://bbs.archlinux.org/viewtopic.php?id=51202
    I'm beginning to feel like Rip Van Winkle
    Edit:  I just did a #pacman -Syu on my x86_64 machine and it asked if I wanted to replace e-cvs with e-svn stuff so I did and sofar no probs.  Sorry ashunter, you might have other issues.  I use gdm on my desktop and slim on my laptop and no probs logging in or shutting down here.
