  • Ubuntu Sapphire RX Vega 64 Nitro+ running slow ?

    After installing Ubuntu 18.04 LTS I tried installing the AMDGPU-Pro drivers as directed (I included Pal / Legacy & Rocm) the GPU went very silent and the desktop runs smoothly. There was only 1 snag, after the install in the terminal said ...
    The following packages have unmet dependencies.
    amdgpu-hwe : Depends: amdgpu-lib-hwe (= 19.20-812932) but it is not going to be installed
    amdgpu-pro-hwe : Depends: libgl1-amdgpu-pro-ext-hwe (= 19.20-812932) but it is not going to be installed

    I'm assuming after looking in the Synaptic Manager it's to do with i386 architecture, as I'm using 64 not 32 I'm assuming I should just skip it ?

    The next step I installed Krita and found page rotation and zoom are very laggy so disabled OpenCL acceleration and works a little better. Then thought I should try Blender with a render which took the CPU 41s and GPU 1:10, I know people have noted this is common but ... (lm-sensors / sensors-detect) the GPU's temp at idle roughly 40c only went up to 51c and the watts (i think) idle 3w only showed as 150w.

    I guess apart from not knowing if the card is installed properly, does it also need to be overclocked ?

    Just an update, still haven't determined the driver installation but have fixed a couple of problems.

    Blender just needed some settings changed when rendering by GPU (tile size mostly). Krita for some reason the version I had installed was the problem so just added the ppa suggested from their website and works fine now.

    So the question still remains, do I need amdgpu-hwe installed ? Did the installation finish or not ?

      The 32 architecture on Ubuntu 18.04 needed to be installed for a full installation, but I've moved over to Linux Mint Tina (Cinnamon) and installs perfectly fine nothing extra to do.
