==Pre-installation==
===Run Updates===
sudo apt-get update
sudo apt-get upgrade
===Reboot===
===Verify that you have a CUDA-Capable GPU===
lspci | grep -i nvidia
===Add location of CUDA drivers to the PATH===
Add drivers to environment path:
nano ~/.profile
With the file opened in the nano editor, scroll down and add at the bottom:
export PATH=/usr/local/cuda-10.0/bin${PATH:+:${PATH}}
Type ''Ctrl+O'' ENTER to save and ''Ctrl+X'' to exit
===Set configuration===
| 28% 29C P8 8W / 120W | 674MiB / 6075MiB | 0% Default |
+-------------------------------+----------------------+----------------------+
==[OPTIONAL] Change power and or overclock settings==
To overclock the cards you can adjust the settings in the NVIDIA applications that is listed in the applications list. This list is available in the lower left corner of the desktop.
sudo nvidia-smi -pl 100
==Disable automatic updates==
'''IMPORTANT:''' Disabling automatic updates creates a security risk. To keep your system updated manually:
sudo apt update
sudo apt upgrade
Automatic updates might interfere with your miner. To disable them, edit the following file:
sudo nano /etc/apt/apt.conf.d/20auto-upgrades
With the file opened in the nano editor, switch off the updater by changing values from 1 to 0:
APT::Periodic::Update-Package-Lists "0";
APT::Periodic::Unattended-Upgrade "0";
Type ''Ctrl+O'' ENTER to save and ''Ctrl+X'' to exit
==Setting up the miner==
For this example, let's look at the currently popular miner T-Rex.
# [https://github.com/trexminer/T-Rex/releases/ Download the last version from their Github here].
# Browse to the Downloads folder using the Files explorer
# Extract the miner from the tar.gz-file (right click and choose ''Extract Here'')
# Move the extracted folder to your home directory by dragging or copy-pasting it there
# Rename the folder to '''trex-miner''' for simplicity (right click and choose ''Rename...'')
# In the folder trex-miner, rename '''config_example''' to '''config''' (at the time of this writing their example was named ''config_example'')
# Open the config file in Text Editor (simply double-click) and change the settings to your liking.
Now start the miner by opening a Terminal and type:
~/trex-miner/t-rex -c config
'''OPTIONAL:''' Adjust intensity setting to your liking by adding -i '''X''', where '''X''' is your desired intensity setting, for example 20.
~/trex-miner/t-rex -c config -i 20
==Troubleshoot==
===PCI Bus Error===
If you encounter PCIe Bus Error messages:
sudo nano /etc/default/grub
Add ''pci=noaer'' at the end of GRUB_CMDLINE_LINUX_DEFAULT:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=noaer"
Type ''Ctrl+O'' ENTER to save and ''Ctrl+X'' to exit and update grub:
sudo update-grub
Now reboot
