~~NOTOC~~ ===== q104: "lspci: command not found" ===== ==== Symptom ==== When running ''lspci | grep -i nvidia'' to check for a GPU, you see "bash: lspci: command not found." This means the ''lspci'' tool itself isn't installed on the system — it's not a sign of a GPU problem. ==== Fix ==== # CentOS 7.9 sudo yum install pciutils On Rocky/Ubuntu, just swap ''yum'' for the corresponding package manager (Rocky: ''sudo dnf install -y pciutils''; Ubuntu: ''sudo apt install -y pciutils''). Once installed, run ''lspci | grep -i nvidia'' again. ~~DISCUSSION:off~~
