Calculate Linux

What is… Calculate Linux?

slide show

You can learn about Linux ® here.
The Calculate project features several distributions, optimized for two distinct groups of people: home users as well as small and medium businesses that prefer open-source to proprietary solutions.

Calculate Linux Desktop is a complementary solution for the Server and together they provide important features like roaming profiles and centralized software deployment.

Calculate Directory Server can successfully replace a Windows NT ® domain controller (Windows clients supported) and provides additional services that can be deployed in a matter of minutes: LDAP, Mail, Jabber and many others.

Calculate Linux is based on Gentoo that is well known for its stability and great performance on a broad range of hardware: from Pentium Pro to modern CPUs.

Why make another distribution?

Most of the modern Linux distributions are intended for enthusiasts, except Novell SLES/SLED, Ubuntu and RedHat EL. However, even if you use these, setting up a client/server environment could be tricky (especially when you have to manage both Windows and Linux clients). We created our own distribution to help other people who want to use GNU/Linux instead of a proprietary OS for their business needs.

How may i check thos…

08/22 - RE: KDE Framework 5? (Iurii Blokhin)

The steps to install KDE Framework 5 are the same as Gentoo. At you own risk. Calculate Linux at now does not have any special settings for Plasma 5

08/22 - RE: kernel name with no extension (Sylvain Bonnemaison)

I still have the same name after unmerge, removing the source directory and emerge again.

cl-kernel is not yet installed on the system. Is it the problem?

How can I reinstall cl-kernel?

08/21 - KDE Framework 5? (sergio ruppel)

Hi, im new to Calculate, been using about a week as main OS, actually its my only OS installed atm...

Thanks, Sergio

08/21 - RE: fat codepage problems (Iurii Blokhin)

This is precompiled in kernel.
In "make menuconfig" -> File Syetems -> DOS/FAT/NT Filesystems:
Default codepage and default iocharset

08/21 - RE: Project: a completely custom-compiled desktop INCLUDING compiled X-org from CLS (Iurii Blokhin)

In CLS is already precompiled xorg, openbox, etc... If you want to build EVERYTHING on your pc - you need to change make.conf
Add to /etc/portage/make.conf/custom

FEATURES="${FEATURES} -getbinpkg" 

and something optimization flags you want.

And then rebuild the system.

08/21 - RE: systemd renamed network eth0 (Iurii Blokhin)

No network interfaces available on the system or no daemons in /etc/init.d?
What ifconfig says?
Try to add new symlinks to /etc/init.d/

08/21 - RE: kernel name with no extension (Iurii Blokhin)

Try to build kernel again. This error was fixed.

08/20 - kernel name with no extension (Sylvain Bonnemaison)


When the kernel is built, the name does not contain calculate or CLD extension. What's wrong in the system configuration?

# eselect kernel list
Available kernel symlink targets:
  [1]   linux-3.14.16- *

I'm using distros (layman) for system profile configuration.


Thank you!
