[BUG]

[endepointe]

Describe the bug

GPU usage information seems to be missing. Toggle GPU box not working. After cloning the ROCm SMI library into lib/rocm_smi_lib (from README(, updating btop from version 1.2 to 1.2.13, the gpu usage information is not displaying. Im curious now if my gpu is simply not being detected by btop.

Expected behavior

1. run btop
2. see gpu usage info in cpu box
3. press 5 to toggle gpu box
4. see gpu information

Same thing happens to me with an nvidia card (3070). Fedora 39 kernel 6.6.4 self compiled. Only reference to GPU are in options, but no trace of it in the main ui, nothing happens when pressing '5'

@endepointe @Botoni Make sure you are compiling from git main. btop version should be 1.3.0 When compiling check that GPU_SUPPORT says true.

Then run btop --debug and post the output of the logfile.

Thank you @aristocratos I've found the problem looking myself at the log, libnvidia-ml.so was named libnvidia-ml.so.1 in my system, so it wasn't found. I created another symlink named libnvidia-ml.so and everything works now.

@Botoni Hey, may I ask how to locate the log file? I'm not able to find it.

how did you find this out? I cant get btop to show gpu usage. Not sure where to start looking for these files.

@alotofentropy @arvvnd

Hi sorry for not keeping up with this. The log files produced by btop can be produced by running the command: btop --debug

The logs are located at $HOME/.config/btop/

Thank you, I will check them out!
