"Cannot access GPU registers, are you root?" even being root

meddario commented 2 years ago

Hi, executing both

radeontop

and

sudo radeontop

I get the error Cannot access GPU registers, are you root?, do I need some special configuration?

Additional info

radeontop was installed by standard sudo apt update && sudo apt install -y radeontop.

Another strange thing:

radeontop -v
RadeonTop unknown

dpkg -l | grep radeontop
ii  radeontop                                   1.2-1                                      amd64        Utility to showRadeon GPU utilization

Try with latest radeontop from git , which currently is RadeonTop v1.3-4-g1552170. You should compile it yourself which is pretty simple and guided in README.

Hi,

I downloaded a tarball of 1.3 and it works, for the record, I had to install (Ubuntu 20.04):

sudo apt install libxcb-dri2-0-dev build-essential pkgconf libdrm-dev libncurses-dev libpciaccess-dev

I'll also try the git version, thanks!
