(solved) removing gnome-mime-data and chemical-mime-data

Hi. I  would like to remove gnome-mime-data. I executed the command #pacman -Rs gnome-mime-data. The result warned that chemical-mime-data depends on gnome-mime-data. So I have to execute the command #pacman -Rsc gnome-mime-data to get rid of gnome-mime-data but also of chemical-mime-data. If I remove both do I run the risk of making the entire system crash?
I have kde installed. I forget to edit /etc/pacman.conf to IgnoreGroup = gnome before running #pacman -Syu. so now I would like to get rid some gnome stuff I found on the system. I have absolutely nothing against gnome. I just want to run only kde.
Thanks for your attention.

You don't have to have chemical-mime-data.  You must've install some chemistry related software. 
Read up mime types so that you're more familiar with them.  Basically, chemistry-mime-data would allow you to double-click a protein databank (pdb) file in a file manager and launch pymol automatically, for example.

  • [SOLVED]Removing gnome 3.x now that cinnamon 2.x no longer requires it

    I've had gnome and cinnamon on my system for a while but am no longer really using gnome.
    From cinnamon 2.0, there are various reports that cinnamon is independent of gnome (although I think it still depends on some other gnome-* packages).
    I'm trying to remove gnome as a DE, while retaining whatever packages are required by cinnamon.
    I tried running the following command:
    # pacman -Rns gnome gnome-extra
    ...I get the following output:

    Thanks karol,
    Running 'pacman -Sqg gnome gnome-extra' produced a fairly long list, I removed the above 'requires <package>' packages from the list and ran pacman -Rns <long list!>
    This threw up a few more errors, which were resolved by removing one or two more packages from the list until pacman would run
    The following ran fine:
    pacman -Rns baobab empathy eog epiphany evince gnome-backgrounds gnome-calculator gnome-contacts gnome-control-center gnome-dictionary gnome-disk-utility gnome-font-viewer gnome-icon-theme-extras gnome-keyring gnome-screenshot gnome-session gnome-shell gnome-system-log gnome-system-monitor gnome-terminal gnome-user-docs gnome-user-share mousetweaks mutter nautilus sushi totem tracker vino xdg-user-dirs-gtk yelp accerciser aisleriot anjuta brasero cheese devhelp evolution file-roller five-or-more four-in-a-row gnome-chess gnome-clocks gnome-color-manager gnome-devel-docs gnome-documents gnome-getting-started-docs gnome-klotski gnome-mahjongg gnome-mines gnome-nettool gnome-nibbles gnome-photos gnome-robots gnome-sudoku gnome-tetravex gnome-weather iagno lightsoff nautilus-sendto orca quadrapassel rygel swell-foop tali vinagre
    pacman -Rns gnome-tweak-tool
    As a result, I've removed about 950 MB of unwanted packages.
    Thanks for the help.

  • [SOLVED] Removing gnome

    Hey guys and girls,
    I have finally become comfortable enough in openbox that i am ridding my laptop of gnome for good!
    I have run these commands so far
    pacman -Rns gnome gnome-extra
    pacman -Runs gnome
    this has done a pretty good job of removing the stuff i dont need.
    however, when i sudo pacman -Syu
    i get 129 targets and 1039.67 MB  to install because it wants to reinstall/update everything I've just removed...
    how can I run pacman -Syu without reinstalling all that gnome junk?
    I assume I need to edit my repo, but Im not sure how, and Im also not sure what to remove and what to leave..
    any help at all is much appreciated

  • Gnome: mime types, file associations and defaults.list

    I installed the new Gnome 2.8 during the weekend and now my file type associations is completely bloated. The mime system is intact - Nautilus recognises files properly. However, Nautilus doesn't know which applications to open a specific file with. I have read other posts and found useful information, but not the solution.
    This post in FedoraForum gave me a hint to what's causing the problem:
    http://fedoraforum.org/forum/showthread … post127530
    It seems that the file defaults.list is missing from /usr/share/mime/applications. Apparently this file contains the associations  between applications and mime types. I have not be able to find out which package should provide this file or how to recreate it. Can anyone help - maybe provide the name of the package that provides this file?
    Thanks,

    Yeah, I got tired of Evolution not knowing about opening *.docs in openoffice.  After several hours of research, the key is the /usr/share/applications/mimeinfo.cache,  /opt/gnome/share/applications/mimeinfo.cache, and the MimeType fields in the *.desktop files.  The mimeinfo.cache in /usr was empty and the /opt one had gthumb and other apps but no OO:
    [MIME Cache]
    application/x-gnome-stones=gnome-stones.desktop
    image/jpeg=gthumb.desktop
    application/postscript=ggv.desktop
    ...snip...
    That's a lot of blather to say that the fix for Evolution/OpenOffice was to add the proper MimeType entry to /usr/share/applications/ooo645writer.desktop:
    MimeType=application/vnd.ms-word;application/msword
    and then run "update-desktop-database".  Problem solved.
    Another problem is that within Evolution it says an attached doc is a "application/msword" and not a "Microsoft Word Document".  Unfortunately this is because freedesktop.org decided to use application/vnd.ms-word instead of application/msword like the rest of the world.  If you check the vnd.ms-word entry in /usr/share/mime/packages/freedesktop.org.xml it defines an alias msword but the new mime system doesn't appear to recognize aliases yet.  The solution I used was to rename the entry to msword.  Another possible solution might be to remove the msword alias from the vnd.ms-word entry and create a new msword entry based on the vnd.ms-word one.  Then run "update-mime-database /usr/share/mime".  Hope that made sense.
    I think the defaults.list is part of the previous GNOME MIME setup cause I don't have one and I'm not experiencing any problems.  For other apps check for the associations in the mimeinfo.cache's and if missing add the MimeType's to the app's *.desktop.

  • White Macbook 2006 random shutdown solved removed cpu heatsink and more

    I picked up a cheap macbook from a secondhand retailer for $300 and it regularly shutdown, froze, restarted as well as the grey kernel panic screen completely random no real pattern. I set about trying to solve the problem swapping ram and hard drive with my identical 2006 macbook (which I had similar problems with last year, fixed that one with a new battery connector cable). The ram and hard drive made no difference so I downloaded istat menus to see if any combination of cpu voltage, current and temperature were causing the random shutdowns. It seemed when the temperature reached certain values the computer would shutdown or freeze(around 30 to 50 degrees). I'd read on other forums about faulty cpu temperature diodes so I reapplied heatsink compound to the cpu heatsink and checked all the wiring for shorts but nothing seemed to solve the problem. I was ready to retire the computer and use it for spares for my other macbook when needed but I pulled the keyboard off one more time and tried something completely radical. This fix requires some forward planning and software installation but it has completely solved my Random shutdowns completely.
    for instructions see my next post *Fix for random shutdowns white macbook*

    Ok this is not for the non technical person but it is quite a simple process with the right instructions.
    This first step is very important install the software coolbook($10) and fan control (Free)( not smc fan control). Set up coolbook to operate the cpu at the lowest speed and voltage for both power adapter and battery(1002MHz and .95Volts). Remove the keyboard to access the computer logic board (instructions can be found at iFixit). Remove the four screws and two connectors holding the heatsink to the logicboard and gently lift the heatsink out (very important that you leave the fan screwed in and connected). Close the computer back up if you wish to test just gently connect the keyboard and loosly sit the keyboard back in. Restart and reset the pram immediately. Let the computer boot up and then open system preferences and configure Fan Control to your liking. So far no random shutdowns for over a week (was getting many a day previously.

    The iCloud was never verified therefore never backing up anything on my iphone 4s because it was the wrong email and now I'm trying to make a new one but it says if I delete the account it will remove it's data from my phone. So if I put delete account will I lose everything on my Iphone?

    This was EXACTLY what I needed about the purchases I made from my device. However, is there a way to re-download other ones you've made from a computer? Because I realized some of them were not just purchased from my device.
    This is a picture of what it looks like now:

    As you can see, the stuff circled in red doesn't give me an option to download from Cloud Beta because it already says "downloaded".
    any way to get around that?

  • How do you remove back up data from the memory storage? my storage data states that i have over 80gb of data used for back ups and i dont know why as i use a external hard drive as a time machine .now my 250gb flash storage is nearly full

    how do you remove back up data from the memory storage? my storage data states that i have over 80gb of data used for back ups and i dont know why as i use a external hard drive as a time machine .now my 250gb flash storage is nearly full.. HELP!

    When Time Machine backs up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of recently deleted files. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as  Backups. The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself. If you followed bad advice to disable local snapshots by running a shell command, you may have ended up with a lot of data in the Other category. Ask for instructions in that case.
    See this support article for some simple ways to free up storage space.

  • Hello, My computer crashed, I removed the hard drive and installed it into a hard drive enclosure and now I am trying to get my Thunderbird data off of it

    Hello,
    Thank you for taking a look at my problem. My Windows computer crashed so I removed the hard drive and installed it into a hard drive enclosure and connected it to my new Windows computer with a USB cord. I installed Mozilla Thunderbird on my new computer and read the different tutorials on this website for extracting data from the external hard drive and installing it on my new computer however I cannot seem to be able to find the files that I need and quite frankly I do not know how to move them once I do find them. I even tried MozBackup but it could not find the files either. I searched for profiles.ini in the hard drive and the only hit I got was a profiles.ini file that was 111 bytes in size. I assumed that this was not what I was looking for but I did save a copy on my desktop. If someone has experience with moving files from a hard drive to a new computer I would be grateful for the help.
    Thanks,
    AN

    lets get with the program. Mozbackup is useless in this situation because it looks for your profile in the location Thunderbird says it is.
    You biggest hurdle is probably setting windows to show system and hidden files. The %appdata% folders are hidden by windows.

  • I have allowed my iTunes Match subscription to expire, because of a limited data plan so can't listen to music outside my house. My music files were removed from my computer and are inaccessible without renewing the subscription. How do I get them back?

    I have allowed my iTunes Match subscription to expire, because of a limited data plan so can't listen to music outside my house. My music files were removed from my computer and are inaccessible without renewing the subscription. How do I get them back?

    Hi,
    I presume you deleted the original files as match would not have done so. Do you have a back up. If so, restore your music from that. If not, your will have lost all your music as this needed to be on your hard drive when you unsubscribed.

  • "Remove all website data," cookies, and extension preferences

    Safari 5.1 Lion
    Can someone please confirm the following (very unfortunate) behavior?
    1) Check the option "Block cookies from 3rd parties and advertisers"
    2) Visit any major site (CNN, CNET, etc.)
    3) 3rd party cookies and tracking data is still acquired from doubleclick, etc. despite step #1
    In other words, Safari 5.1 does not seem to be blocking third party cookies. I have seen other threads documenting this. What's worse is that "removing all website data" (Preferences | Privacy tab) *also* deletes your extension preferences. ***?
    Chrome and Firefox separate "local data" (extension prefs and site offline storage) from cookie/tracking data. Safari is no longer an option to me until this is fixed.

    I, too, am perplexed by this change. Then again, I've been perplexed by most of the changes Apple has made to products/os in the last few years. I'm thinking that I may not only change browsers, but hardware/software also. It's issues like this that make me wonder if anyone on the Apple design team actually uses any of their products, or maybe they think we are all just too ignorant to be able to use a computer.
    Making things simple to use shouldn't equate to removing advanced functionality, but it seems that's what Apple believes it to be.
    Really disgusted now.
    Thanks Apple.

  • [SOLVED] Removing all uneeded packages, GNOME Issues

    Just setup arch in VirtaulBox, and I got everything working! Hooray, only took 4 tries, but thats what I call the learning process and I love it!
    My issue was this:
    Gnome wouldn't save my theme settings! Each time I ran it with startx my theme settings were reset to default! I'd change the theme to DarkRoom and change my icon set to Tango, and then after logging out, and running startx again, poof, back to default. My background, however, DID save.
    So after that experiment, I've decided to use KDE, just cause I wanna do it, no real reason, besides learning as much as I can
    I've gone and removed gnome:
    pacman -Rc gnome
    Now I'm trying to clear out all the excess packages, so I ran:
    pacman -Qdt
    It shows a whole bunch of stuff, so what I'm asking is this: How can I clear out all unneeded packages, orphaned packages, etc
    Coming from the Debian based world, I know I could use apt-get autoremove to get rid of unneeded packages, and I would like to know if there is a way to do this using pacman
    If not, is it possible to run pacman -Qdt and export the output to a file, then run pacman -R  and have it access that file and remove all those packages?
    Thank you for the assistance!

    I have a 2007 Mac Book Pro and a Genius told me that it is "vintage" and that the "logic board" is bad and no longer supported.  He removed the hard drive and told me to buy a "sled" to retreive the data.  Is it worth trying to fix it so that I don't have to buy a new one?  Where should I take it?  Thanks.

    djgornik,
    if the Genius is correct and the logic board is bad, then replacing the logic board would be fairly expensive. What problems are you seeing with your MacBook Pro that caused you to visit the Genius in the first place? Whether it’s worth trying to fix it or not depends on your particular circumstances, such as your willingness to trade time for money in pursuing repair vs. replacement.
