Hi.
I have allways used windows with phoenix, now i am thinking about to change it top linux ( ubuntu) and i am making some tests with it, i have a problem , i can not load the config file properly, neither make phoenix tu use the extra settings i use. it only loads default values meaning i do not get the extra hashrate with overclocking, and undervolting, here are my example files :
For AMD cards, you need to set the kernel parameter to enable overlooking and voltage adjustments in Linux.

For Nvidia cards, you need to enable coolbits in the xorg.conf file for each card to allow overclocking and power limit. For overclocking a single card, you can run X-server as a standard user. To be able to set overclocks and power adjustments for multiple Nvidia cards, the X-server needs to run as root.
