The script attempted to perform driver selection by echoing the `$gpu_info` variable, but the variable had not yet been populated with the output from the `lspci` command. This resulted in the `if` condition always failing and the driver package incorrectly defaulting to `nvidia-dkms` for all hardware. This commit moves the `gpu_info` assignment to before it is referenced, ensuring the detection and selection logic works as intended.
