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.

04/22 - RE: Bad page map in process uksmd (Adrien Daugabel)

Hi, thanks for your answer.

Since I posted here, I had some other errors but without uksm.

I think I have a problem ( faulty RAM chips )

I am going to test to remove each RAM and after, I will install the latest kernel.


04/22 - RE: Bad page map in process uksmd (Iurii Blokhin)

Try to emerge =sys-kernel/calculate-sources-3.19.5
Kernel version 3.19 without UKSM and may be problem will be solved.

Thank you!
