To find out if the PCIe/AGP/VGA driver is installed on a Linux system, you can use the lspci command to list the PCI devices on the system and the lsmod command to list the currently loaded kernel modules.
To list the PCI devices on the system, you can use the following command:
$ lspci
This will list the PCI devices on the system, including the PCIe/AGP/VGA device. You can look for the device name or vendor and device ID to determine if the device is installed on the system.
To list the currently loaded kernel modules, you can use the following command:
$ lsmod
This will list the kernel modules that are currently loaded on the system. You can look for the name of the driver for the PCIe/AGP/VGA device to determine if the driver is installed on the system.
Alternatively, you can use the lshw command to list the hardware components on the system, including the PCIe/AGP/VGA device. To list the hardware components on the system, you can use the following command:
$ lshw
This will list the hardware components on the system, including the PCIe/AGP/VGA device. You can look for the device name or vendor and device ID to determine if the device is installed on the system.
These are just a few examples of how to find out if the PCIe/AGP/VGA driver is installed on a Linux system. The specific steps may vary depending on the distribution and version of Linux that you are using. You can refer to the documentation for the lspci, lsmod, and lshw commands for more information on how to use them.
