I have Thinkpad T490 with Nvidia mx250 dedicated gpu.
When btop is run by root user it detects both the GPUs, but when it is run by user raj only the nvidia gpu is detected.

• I tried copying the root's config, nothing changed .
• Switched between KDE and Xfce, still no change.

If btop is able to detect both the GPUs, why is only the nvidia one shown ?
Even simply running sudo btop shows both the gpu.

On my Proxmox system (Debian) I had to sudo setcap cap_dac_read_search,cap_sys_admin+ep /usr/local/bin/btop to get an Intel iGPU to show up when not run as sudo.

Thank You for your reply and I am really sorry for the late reply, i got busy with college and other stuff.

For me sudo setcap cap_dac_read_search,cap_sys_admin+ep /usr/bin/btop this worked.

There was no btop directory in /usr/local/bin/ .
I guess we are elevating btop's privileges so that it can access restricted system data.

Again Thank You and I apologize.
