Because in Foresight you always get software you otherwise will have to wait for in other distributions.
- It gives you the latest in GNOME software
- It uses the modern Conary package manager.
- Our community is cool
- It is easier to build packages on your own than in any other distribution.
- Foresight uses "rolling releases".
- It's green
No, we do not provide a live CD/DVD anymore.
However, there are a number of ways to try out Foresight Linux, including VMware image and others.
- Visit our Downloads page for more information.
We provide a cryptographic checksum (using SHA-1 – Secure Hash Algorithm 1) for each downloadable iso image. It is always a good idea to verify the download against this checksum to avoid burning a disc that won't work.
You can check that the checksum of the image you downloaded matches the checksum provided for that image on the download page. In addition to the iso image you downloaded, you will need to download the file called SHA1SUM and save it to the same folder as your downloaded image.
If you downloaded the iso image to your ~/Download folder, open a terminal and check the SHA-1 checksum like this:
If the iso image is not corrupt, you should see something similar to the following output:
Download the windows version of the sha1sum tool and save it to the folder where you saved the iso image and the SHA1SUM file. Then open windows explorer and navigate to the folder where you saved the iso image, the SHA1SUM file and the sha1sum.exe tool and hold down the SHIFT key while right-clicking on a blank area inside the folder.
This should bring up a context menu with the option "Open command window here" as shown in the screenshot below:
In the command window, you can verify the iso image SHA-1 sum as shown below:
This depends highly on your system. We recommend at least 256 MB of RAM - better more.
- Intel Core Duo T2300 with 1GB RAM, x86 2.0.6 DVD: 15 minutes from start of install to logged in and running applications.
You can search and browse for packages built for Foresight using the Repository Browser at rBuilder Online. Even though the package you are looking for isn't packaged specifically for Foresight, chances are that it will still work. If it doesn't, you can always use the Conary package manager roll back feature to reset your system to its prior state.
Because of its rolling update nature, security updates can quickly be rolled onto installed systems. At present we have no dedicated security team, but fixes are usually applied and rolled out from day-to-day.
Foresight uses the Conary Package manager. To interact you can use PackageKit (http://www.packagekit.org/).
- Add/Remove Software from the System->Administration menu
- If updates are available you will see notifications of PackageKit through the notification area.
see also How do I use PackageKit?
or you can use the conary command line tool:
- man conary
From the Conary wiki: Conary replaces existing software package management solutions (such as RPM and dpkg) with one designed to enable loose collaboration across the Internet. Unlike traditional packages, Conary packages are defined by components and files stored in networked repositories.
Take a look for yourself at the OpenSSH package recipe for Conary vs. the RPM package.
- sudo conary update packagename
- Look at rBuilder to find further packages. There you can click on the name of the results and from that trove you see a Version string like : /reponame.rpath.org@rpl:devel/5.1-1-1. To install this package you would then make a conary command: "conary update packagename=reponame.rpath.org@rpl:devel". This will fetch the package from the given repository. (Please be aware that not all package may be a good choice and do have the same quality. So also take a look at the Project where the trove belongs. If unsure ask in IRC, mailing list or forum which trove you could use in Foresight).
See also HOWTO add package X!
Use the "Add/Remove Software from the System->Administration" and search for "openoffice.org-locale". In the list, select the package corresponding to your country and install it.
Once installed, you can find this in all the OpenOffice.org applications in "Tools -> Options" under the Language settings line.
Before you log in press "F10" at login screen. "Select Language" and choose your local language.
We are working on a new theme that shows a button for this switch
This is a rare issue but check the following:
- Check if other applications can produce sound. If yes its not a general desktop problem but a problem of only one application.
- Did you disable sound somehow (maybe via notebook button, please also check cabling and power)
- Right click on the loudspeaker symbol (standard location in the upper right corner) and select to Open Sound Mixer. Then play with the controlers, disable and reenable one volume control by clicking on the small loudspeaker symbols (like for master, PCM) and test after each step if sound is working again. Often this helps.
If you still don't get sound in JIRA (see HOWTO file an issue in JIRA.
You do NOT really need avisynth.dll! Just place "-playlist" between the mplayer command and the URL.
You must install the package: gst-plugins-ugly.
If you are unsure if this is a bug come to the IRC irc://chat.freenode.org/foresight and describe your problem. Please be prepared to paste some stuff in the Pastebin. Or you can file a bug report in JIRA issue tracker.
In order not to break some older software that makes some bad assumptions that the Linux kernel would never use a major version higher than 2, we use a patch that has also been used by Fedora and is used by Oracle to report the version as if Linus Torvalds had kept using 2.6.x versions instead of moving to 3.x versions. (We expect to quit using this in Foresight Linux 3.)
In Foresight we use similar stuff as Red Hat/Fedora. So you can use chkconfig to do that.
This will stop exampleservice and then remove autostart from init scripts.
Read this HOWTO.
ATI's binary drivers do not work with Compiz due to not supporting the texture_from_pixmap OpenGL extension. Use the open source ATI driver, "radeon" to enable Compiz.
Our kernel has most of the stuff anyone might need built in. So in 99.9 % cases there should be no need to recompile. If you need the Kernel sources add the trove kernel:build-tree via commmand line:
See "man e2label" (Change the label on an ext2/ext3 filesystem). Read the label of a partition with "e2label partition" or set it with "e2label partition label". The nice thing about labels is that if something changes in the naming of partitions (like /dev/hda ->/dev/sda recently) the kernel still can work with the partition as it can recognize the label name.
