Hello, i have amd rx6800 gpu and i just want to test it to mine something. The card was second hand so i want to know if it works in mining too.
I have registered on nicehash and found that no any Linux software available except dedicated nicehash distro.
As far as i know cgminer 4.9.2 which available via apt no more works for GPU.

If you dont want to use ready-made software like Hive-os etc, but would like to just install the graphics driver and run any mining program from the command line, then you can follow this recipe. It works for my RX6600 cards.

Goto the AMD web site and download the latest driver .deb file from

https://www.amd.com/en/support

If you enter your GPU model, RX6800, then the latest version to download is amdgpu-install_5.7.50702-1_all.deb

After this file is downloaded, open a terminal window, cd to the ~/Downloads folder and run the following commands to install driver:

sudo apt-get install ./amdgpu-install_5.7.50702-1_all.deb
sudo amdgpu-install -y --accept-eula --opencl=rocr,legacy --usecase=graphics,opencl

Then edit /etc/default/grub and add these kernel parameters to it:
Change the line where it says GRUB_CMDLINE_LINUX_DEFAULT to
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash text noapic amdgpu.gpu_recovery=1 amdgpu.ppfeaturemask=0xffffffff"
and save, then run

sudo update-grub

Then register your user id in the video group:

sudo usermod -a -G render $LOGNAME
sudo usermod -a -G video $LOGNAME

After this you may need to reboot for your system for it to register your card.
