Modprobe question (pre-install drm modules via modprobe on start-up)

I'm trying to follow the dri building guide but archlinux doesn't have /etc/modules.conf so what do I do?
2.6.x kernels:
pre-install <drm module> /sbin/modprobe "-k" "agpgart"
pre-install agpgart /sbin/modprobe "-k" "<agp chipset driver>"
Thats what I'm trying to do. For more info go here:
http://dri.freedesktop.org/wiki/Buildin … 16c0c945a7
I don't know if I should make a /etc/modules.conf or add what to what. Specific instructions would be great. Btw i have a via chipset (vt8237) and an ati radeon (9800 pro) graphics card. Thanks in advance.
btw correct me if I'm wrong:
/etc/rc.conf:
LOCALE="en_US.utf8"
HARDWARECLOCK="UTC"
USEDIRECTISA="no"
TIMEZONE="America/Chicago"
KEYMAP="us"
CONSOLEFONT=
CONSOLEMAP=
USECOLOR="yes"
#not sure if a line in MODULES=(...) should be made or not
MOD_AUTOLOAD="yes"
MODULES=(pre-install radeon /sbin/modprobe "-k" "agpgart"
pre-install agpgart /sbin/modprobe "-k" "via_agp")
USELVM="no"
HOSTNAME="archie"
eth0="eth0  192.168.0.10 netmask  255.255.255.0 broadcast  192.168.0.255"
INTERFACES=(eth0)
gateway="default gw 192.168.0.1"
ROUTES=(gateway)
DAEMONS=(!syslog-ng !netfs !crond network hal fam alsa gdm)
Now what do I put in /etc/modprobe.conf (if anything) because I'm really confused

By default, the only modprobe.conf file that exists in a new install will be blank.  The file is mostly used to either pass specific arguments to a kernel on boot-up so these args will be then inserted into userspace and used by whatever app needs them.  EG: There are examples of this regarding Alsa and blacklisting or adding special arguments in modprobe.conf for the hda-intel on-board soundcards.
As to what to put into that file, I can't tell you (didn't read the link yet).  I can tell you that you likely should just create it first then re-read what you're trying to do.  These lines won't go into rc.conf, that much I know:
pre-install <drm module> /sbin/modprobe "-k" "agpgart"
pre-install agpgart /sbin/modprobe "-k" "<agp chipset driver>"
In all likelihood you must either insert these into the modprobe.conf file itself OR run them as root commands.  As I said, haven't read the link so I don't know for sure.  Sorry, and I don't have time to read up much more.

  • If Mountain Lion comes pre-installed on my machine, how can I get the OS discs if it's only available via download?

    Had someone ask a very good question, I think.
    If you buy a new Mac that has Mountain Lion pre-installed on the machine, you are able to download updates as they come out; however, you can't necessarily download the Mountain Lion installer via the App Store since it came already installed on your computer.
    So my question is, how can you get a OS disk/drive of Mountain Lion if your computer fails? I know Apple has the Recovery drive, and even the Internet Recovery drive, along with Time Machine and whatever else, but what if none of these options are available to recover the computer?
    I suggested to the person to clone their hard drive using the 30-day trial of Carbon Copy Cloner. That way, they have a bootable image with the OS already available in case they run into this option. BUT, what if that isn't even an option? How does one go about recovering their computer if no OS disc of Mountain Lion is available?
    I haven't been able to find anything about workarounds besides the methods I mentioned above, so please tell me if I am missing something.

    you can't necessarily download the Mountain Lion installer via the App Store since it came already installed on your computer.
    Not true. You can go to the Mac App Store and download the installer
    (from the link that WALTER-MILANO-ITALY posted above)
    Install OS X Lion or OS X Mountain Lion
    If you completed your installation of OS X, your installer may have been removed after your successful first login to OS X Lion or OS X Mountain Lion.  Mac App Store's Purchases page should show Install OS X as being "Installed", and disallow its download, when viewed from a computer running OS X.
    To redownload the installer on a computer running OS X Lion or OS X Mountain Lion, press and hold the Option key while you click the Purchases tab. If the button to the right of the Install OS X Lion or OS X Mountain Lion item doesn't change to "Install" and allow you to download OS X, use Spotlight to search for "Install OS X Lion or OS X Mountain Lion" on your computer.

  • SOLVED: Building a streamlined kernel via modprobed-db

    Hi
    I was trying to use the modprobed_db daemon (activated by systemd) to collect all used modules on my hardware in order to build a more streamlined kernel.
    Here is the wiki:
    https://wiki.archlinux.org/index.php/Modprobed-db
    I modified the arch linux PKGBUILD of the kernel by adding these two lines:
    sudo /usr/bin/modprobed-db recall
    make localmodconfig
    Unfortunately the modprobed service doesn't catch the loop module, although I'm using it.
    I then tried to simply add some modules in ~/.config/modprobed.db, but this resulted in the error "loop: module not found", when I tried to build the kernel via makepkg.
    What is the right way to manually add modules to the modprobed database?
    thanks

    I made a huge mistake that was the reason for the abovementioned error:
    I tried to manually add modules into the modeprobed.db and then do a "recall"  during makepkg while being already in a module-wise restricted environment of a previous custom kernel build!
    It is clear that the "recall" mechanism during the build cannot work, when the booted kernel/the running system doesn't contain the searched for modules. One has to manually add and recall modules for a custom build from within a fully fledged arch linux generic kernel where everything is at disposition and can in fact be modprobed!
    sorry for the inconvenience.

    Your welcome, gald to be of help
    Welcome to Apple Support Communites and to the Mac, after a little time you will be flying!
    Make sure if you have not done so yet to run software update to make sure you MBP is up to date, you can do this by clicking on the Apple logo at the top left on your menu bar, and clicking on Software update.
    One other thing that will help you when posting here is to make syre your profile is up to date/correct. You have in your profile as of now your MBP model and year which is freat, but you have for your operating system, iOS(mobile devces) 7.02, which would be for and iPhone, iPad, iPod. Your MacBook Pro operates on OSX (which in your case should be 10.8.5, you can find this info under the Apple logo, About this Mac) having this info available to anyone reading a question post is very helpful for them offer advice/sugesstions that may apply to your particular OSX, as well as eliminating confusion.
    Thank you for the green check, by marking your respones it helps other users to find solutions if they are having a similar issue, if you are looking for something, after typing yor question, check the right hand side bar under "More Like This" and sometimes you may find an answer there.
    Synergy is a great thing.
    Thanks for using Apple Support Communities  and enjoy your new Mac.
    One more suggestion is to purchase AppleCare it will extend your warranty to 3 years and you will also have free phone
    in-store/online for the entire period. I have done this with my families machines and found it to well woth the relativly small investment.

    Hello,
    Yes, normally holding alt key or option key will show your boot choices, but some Linux distros need a boot manager installed.

  • Question about activation key for pre-installed software after hard drive failure.

    I had a hard drive failure on my MacBook Pro last week and had it replaced by Apple.  When I restored my computer with a Time Machine backup, Office 2011 wants an activation key to start up again.  Problem is, I had Office pre-installed when I bought my MacBook by Apple.  Where do I get the activation key to get it working again?

    hi Matteo,
    Welcome to the Forums.
    Can you try the following:
    1. Check this guide on how to obtain a Windows 8.1 ISO (see Option One)
    2. Follow this guide to make a bootable UEFI Win8.1 installer via DVD/USB flashdrive and use it to install Windows (the installation should be able to detect the Windows 8.1 product key in the UEFI firmware that should automatically activate Windows).
    Let me know your findings.

  • How to remove/uninstall custom installed perl modules?

    Hello all.
    Yesterday I upgraded from 10.3.7 to 10.4.5, then started to reinstall a bundle of perl modules (via the Terminal and 'perl Makefile.PL -- make -- make test -- [sudo] make install').
    As I saw too late, some of those modules I installed are now part of the standard OS X installation -- now some perl modules are twice on my machine, the 'originals' (so to say) in '/System/Library/Perl/5.8.6/...', and the 're-installed' are -- as usually -- in '/Library/Perl/5.8.6/...'.
    My questions:
    (1) Can these duplicates do any harm while executing perl code?
    (2) Is there an easy way to get rid of the duplicates (e.g., move the associated files in '/Library/Perl/5.8.6/...' to the trash)?
    Fortunately I have saved the terminal output of every installation, so it should be easy to find everything that was changed.
    Any advice is appreciated -- thanks in advance.

    Perl has a list of paths it searches when it needs to find a given module, similar to how the shell uses the PATH variable. If the things you installed are in a directory after that which contains Apple's official stuff, your stuff is invisible. Check the section labeled "@INC" in the output of 'perl -V'...that list is searched top-to-bottom.
    If what you installed is ahead of Apple's but what you installed is at least as high a version number as Apple's, again no problem in general. The modules Apple supplies have genereally quite stable API, so there's no problem if a program expects Appl'es but gets yours instead. OTOH, if you have a lower version, there could be trouble, since things may rely on the features only present in new versions (something for a certain OS X would reasonably assume "the stuff that came with that OS X" as a minimum).
    Anything you installed manually you can remove manually as well, using "rm" or dragging stuff to the trash. Modules often install a .packlist file somewhere in $arch/auto/ in your perl lib dir.
    I think you can often do '[sudo] make uninstall UNINST=1' to uninstall, assuming you kept the original builds or feel like redoing 'perl Makefile.PL' in the exact same version of the modules you installed. However, the 'uninstall' target is generally frowned upon by perl folks.

  • Still necessary to manually install kernel modules with CUPS?

    I'm just setting up my system with CUPS for printing. In the "Configuring CUPS" section of the wiki, you're instructed to install the appropriate kernel module with modprobe for using a usb or parallel port printer. With my usb printer and kernel 2.26.9 I found this is unnecessary. Plugging in the printer caused the module to automatically load. Is this because I'm using input hotplugging? And in any case, should the wiki be edited to reflect situations where loading the module manually is no longer necessary?

    Sure, feel free to edit the page to reflect what you're seeing, which is udev autoloading the appropriate module when it detects the device. This functionality has been in place for a long time, and is not related to input hotplugging as used in xorg (not sure if that's what you're referring to above).

  • How to view pre-installed License file

    Hi,
    I was told we that 6296 comes with pre-installed 18-port license but I could find any.
    There is nothing under installed license. All I can find is 180 days grace period.
    Is pre-installed 18-port license viewable via license management?
    Thanks,
    Harry

    Hi,
    No, you cannot view your default license. you can only view additional license as well the grace license (180 days).
    you can configure the port normally and the base license should cover up until the certain port number, before start using the grace license.
    And the additional Modular also give you another base port license (another 8 port if I'm not mistaken), but you can use it in any port, not only on the module. when you unplug the module, the license is removed, and if the port is greater than the licensed, it will go to the grace license.
    Hope it helped.
    Thanks,
    Pieter

    Hi sasi4urs,
    The only way to restore the preloaded apps is to do a factory restore. Alternatively you can download it via PlayStore.
    Thanks.

  • Any difference between pre-installed apps and previous versions?

    I just bought a MacBook Air. I immediately transfered everything from my Time Capsule backup of my 2008 MacBook. The software on the MacBook was completely up to date via the App Store or Software Update. It didn't occur to me to consider that the new Air came with software pre-installed until just now.
    Now I'm wondering if I overwrote anything important or if the Time Capsule/Time Machine restore takes into account anything that was pre-installed or if all the software was the same already and it doesn't matter. Normally, I could just use the included restore disks that come with the computer to answer this question myself but with the new Airs, there are no disks.
    So I don't really understand how something like a new MacBook Air works. If I wiped the disk and used Lion Recovery would I get everything back that was on the original installation? This seems logical but I don't know if it is true. Anyone know the details about how this works?
    Thanks.

    Just to double check.  Go into the Purchased tab of the App store.  You should see the apps are "installed".  If they have a button that says "install", I'd do that.

  • Drivers from various HP pre-installed software

    Hello,
    I Have an HP ENVY 6 1040EW Ultrabook.
    Because I had issues with my windows system I had to reïnstall windows with disks because a manual factory reset was not possible because of dammaged drivers.
    There where no disks for this particular laptop so i had to use normal windows 7 recovery disks.
    My problem:
    I recovered Windows 7 with my recovery disks and ofcourse my old pre-installed software was not on my PC.
    But I really liked HP coolsense, Beats Audio, HP connection manager and the HP service software to store safely my usernames and passwords. But I can't find the software on the HP website.
    Tnx for reading and answering my question.
    Greetings,

    Hi, Bart:
    See if this IDT audio driver from your PC's support page installs the Beats software too.
