We do our best to offer you a most convenient system for work, using the original installer, redesigned user interface, templates, Calculate utilities and Gentoo Portages. The system is distributed as an installation image, which contains chosen software. Most of the software we have included come under the free license, thus allowing you to install, distribute and modify the source code.
Below is the complete list of our distributions with their abbreviations:
To obtain administrator rights in the system running from livecd use login root with password root. Access to the desktop CLD, CLDG and CLDX can be obtained by the user guest with password guest.
Network Setup in CLD, CLDG and CLDX is performed with the Networkmanager. The program has a graphical interface with which you can configure both wired and wireless networks. When you load the program, it tries to bring up a network interface and obtain an IP address from a DHCP server. Start the program using the icon in the upper right corner of the screen.
Network Configuration of CLS, CDS and CSS is performed through a configuration file /etc/conf.d/net, help on setting up a network can be found in /usr/share/doc/openrc/net.example. After changing the settings, restart the network interface:
/etc/init.d/net.eth0 restart
Before installing, you may need to change the partitions on your hard disk. To set the CLD, CLDG and CLDX, we recommend that you use the partition of at least 10 GB. More detailed hardware requirements can be found here. The swap partition (swap) will normally be twice the size of RAM. If the swap partition already exists, the system will use it. It is wise to have a separate partition for personal files (/home). See more detailed recommendations on partitioning here.
The CLD distro uses Partitionmanager to change the disk partitioning, while CLDG and CLDX use Gparted. You can also partition the disk in the graphical installer, using cfdisk utilities. Note that CLS and CDS contain only the command line utilities: fdisk or cfdisk.
To view a list of existing partitions, open a console as user root and type:
fdisk -l
Note: To obtain root permissions in console, use su or sudo.
If you are new to Linux, you will need a bit of time getting used to the headings differences.
In Linux, partitions are referred to as sda1, sda2, ... instead of the usual C:\, D:\, ...
You can also use the existing partition or create it from Windows. To determine the selected partition in Linux, remember the sequence of its location and size. Usually, drive C:\ corresponds to sda1, disk D:\, to sda2.
Installing Calculate Linux 10.9 or higher performs by program cl-install. CLD, CLDG, CLDX and CLS distros have a graphical front-end cl-install-gui. The program can be run by clicking on the icon "Calculate Linux Install" on the desktop.
To install system to second partition of the hard disk using cl-install, run the following command in terminal with root rights:
cl-install -d /dev/sda2List of most commonly used parameters:
During installation, the program will extract stage4 - the image of the system - and performs the initial configuration using templates.
Before you begin, we highly recommend that you make a backup of your data on a flash drive.
To install the system on the USB-Flash uses a command line utility cl-install. Plug the flash drive to your computer. If you don't know the device name of your stick, run the following in console with the rights root:
fdisk -l
If your flash drive was defined as device /dev/sdb, type in console to install the system on it:
cl-install -d /dev/sdb1
After installing the CLD, CLDX and CLSG you get two users: root and guest (if you have not specified other user accounts). The user guest can get access to the graphical environment: use the username guest with password guest to login.
CLS has by default no graphical invitation to enter the password. After installation you can login as root and launch window manager typing:
startx
To become the root user, use the command "su". More details on creating user accounts can be found here.
By default, you can log into the system remotely using ssh only by root. To add a space for other users or to replace the root user edit the options AllowUsers in /etc/ssh/sshd_config. We recommend to deny the remote access for the root user.
Calculate Linux is a rolling-release distribution. You can update the system virtually unlimited number of times, using the "emerge" software manager. To update all of the installed packages, execute:
layman -s calculate eix-update emerge -uD world
To install additional software, update Portage:
eix-sync
After that, you can upgrade existing or install new versions of programs with "emerge". A quick reference can be found here. Read also the System Update Guide.
