1 – Release Notes
A new version of GL-Z is available for Windows 64-bit, Linux 64-bit and Raspberry Pi (for Raspbian Buster only). GL-Z is a CPU / GPU monitoring and OpenGL / Vulkan information utility made with GeeXLab.
This new version of GL-Z improves the CPU and GPU monitoring support especially on Raspberry Pi platform. And now, the CPU / GPU monitoring is the default mode when GL-Z is launched. If you want to display all data, you have to use the GLZ_all.{bat|sh} script.
GL-Z on Windows 10 + Intel Core i7 8700K + NVIDIA GeForce GPUs:


GL-Z on Raspberry Pi 4 (Raspbian Buster):


GL-Z on Linux Mint 19.2 + AMD RyZen 7 1700 CPU:

Version 0.5.0.1 - 2019/11/27 - Linux: updated with GLIBC 2.23 support + GeeXLab GeeXLab 0.29.7. Version 0.5.0 - 2019/10/04 - Raspberry Pi: added monitoring of CPU and GPU clock speeds, voltage and temperatures. - all platforms: updated the CPU and GPU monitoring. The OpenGL memory load has been added to the monitoring section. - updated the csv file export - updated with latest GeeXLab 0.29.3 / 0.29.2 versions.
How to start this on Ubuntu ?
Download the zip file for Linux 64-bit, unzip it where you want and double click on GLZ. If you have a recent version of Linux Ubuntu (with GLIBC 2.27), it should run. You can also start GLZ in command line using GLZ_all.sh.
I tired that. I got massage
delevic@rig:~/Downloads/GLZ_0.5.0_linux64$ ./GLZ_all.sh
./GLZ: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.27′ not found (required by /home/delevic/Downloads/GLZ_0.5.0_linux64/dylibs/libgxc_r_linux_x64.so)
Ubuntu 16.04
I will try to install GLIBC_2.27
Ok, let me know if you manage to install GLIBC 2.27 and run GLZ on ubuntu 16.04.
I thing 2.23 is max for 16.04. Do you have any version with glibc 2.23 ?
I have no version with glibc 2.23. I must say that glibc is an annoying issue with Linux. I zipped the glibc 2.27 of mint 19.2, you can try it (try to put the so files in glz/dylibs/ folder. Maybe you will have to update the rpath of some dylibs…):

I will try again to force GeeXLab core libs to use older versions of gclib. I did that years ago and it worked fine but the last time I tried, I spent (wasted is better) hours without success…
I installed ubuntu 18.04. GeeXlab starts, but it doesnt see nvidia gpu p106-100, only two amd rx 580. But only that.Take a look:

I can get readings form amd driver like you can see on picture.
NO Raspberry PI 64bit !?! arm64 ….
Raspbian is 32-bit, GL-Z is for Raspbian => GL-Z is 32-bit
Ask the Raspberry Pi Foundation to release a 64-bit version of Raspbian.
Hi.
I got this running OK on Ubuntu LTS, but I don’t get the GPU usage for my AMD card. The card is recognized, but the usage and temps are at 0 all the time.
It seems that is looking for the proprietary driver if I’m not mistaken, and I’m using (like everybody else with an AMD card) the open source ones.
“sh: 1: aticonfig: not found
cat: /proc/ati/0/biosversion: No such file or directory”
Other than that everything seems OK. is this tool only meant for the AMD proprietary driver?
Still me, (replying to myself)
Here is some data/logs:

I coded the GPU monitoring for Radeon on Linux long time ago and I think it’s only for AMD proprietary driver. But if there is a way to read GPU temp + usage with open source driver (links?), I will add it…
What I usually do is read the “amdgpu_pm_info” file:
sudo cat /sys/kernel/debug/dri/0/amdgpu_pm_info | grep -E “Temperature|Load”
Which will show: https://imgur.com/H9I64ny
In case the image is not available, the output is:
GPU Temperature: 41 C
GPU Load: 82 %
As for the proper documentation I must confess I’m not sure where exactly you’ll find that. The above method is what you can usually find on various Linux forums/wiki etc, such as:
https://wiki.archlinux.org/index.php/AMDGPU#CLI_(default)
I tried to post various apps that monitor the GPU on Linux+Mesa drivers (maybe you could examine the source code) but
they were apparently seen as spam.
I started a prototype that monitors AMD GPU on Linux using DRM:

I will post the binaries on the HackLab as soon as possible so you’ll be able to test it.
I will also check the /sys/kernel/debug/dri/0/amdgpu_pm_info file …
Excellent. I am waiting for binaries. Until then I am using watch cat /sys/kernel/debug/dri/0-n/amdgpu_pm_info
I am using DRM for overclocking.
