Wrong Graphics card detected

[dcar]

I have a machine which I'm using for ML experiments. I'm looking to use PTS to see whether or not the CPU is causing a bottleneck using standard Linux utils and PTS. However when I run 'phoronix-test-suite system-info' PTS doesn't seem to pick up the GPU. Instead it lists the discrete graphics card.

I have an NVIDIA GTX 1070 which is running fine for these experiments. Where does PTS pick up the configuration for which graphics module to use. Is it configurable? I couldn't see anything on the documentation for this so I assume this needs to be configured on the OS somewhere?

The main place it picks it up is glxinfo... Do you have glxinfo installed? (mesa-utils package on Ubuntu) otherwise it might end up just pulling the data from lspci. Also do you have nvidia-settings in your path?

[dcar]

Thanks for such a quick reply Michael

I have mesa-utils installed. The output doesn't look correct

name of display: localhost:10.0
X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  154 (GLX)
  Minor opcode of failed request:  24 (X_GLXCreateNewContext)
  Value in failed request:  0x0
  Serial number of failed request:  41
  Current serial number in output stream:  42

I also have nvidia-settings. Interestingly when I run it, the wrong GPU seems to be displayed. It's showing a GT 730M rather than a GTX 1070. So perhaps this is my problem if this is where the config is pulled from

[dcar]

I have my suspicion that this is driver related. The error below creates some search hits that relate to driver/setting versions and nvidia/nouveau drivers. I might need to play about with the options here

$nvidia-settings --glxinfo

libEGL warning: DRI2: failed to authenticate
