A BIG welcome to Linux!
With PCLinuxOS, open up the Konsole program. This will get you a terminal emulator (i.e. a command-line prompt). From there, type in "/sbin/lspci -v" and press Enter. This will run the lspci (
li
st
PCI) program, which will scan your hardware's PCI buses to see what sort of hardware you have. The "-v" will make lscpi output extra details (i.e. "-v" means "verbose"). You'll see a bunch of information appear in Konsole. Just copy and paste this into a forum post. It will help us determine which drivers you will need.
You will find the most difficult part of Linux is unlearning Windows. Here's a brief description of directories in Linux:
/bin. This is where the command-line binaries (i.e. executables) are. These are very simple programs that are used by more complex ones.
/usr. This contains the following directories:
/usr/bin. This is where all your applications are (including Konsole and KDE).
/usr/games. This is where a lot of your games are.
/usr/X11R6/bin. This is usually a symbolic link to /usr/bin, but it contains programs specific to X (i.e. the X server, startx, xinit, and a bunch of xclients).
/usr/local/. This usually has nothing but a few directories (servers, however, use this a lot).
/usr/share. This shares hardware-independent data for programs (i.e. bitmaps, sound effects, documentation, some configuration files, etc).
/usr/src. This is where source code to programs you build are stored. This will probably be empty for you.
/usr/lib. This stores application libraries (this is kind of like C:\WINDOWS\System32 in Windows).
/usr/sbin. This contains applications intended to be run by the superuser (i.e. root).
/etc. This stores the system-wide configuration. Programs you install may store their default configurations here. Also, this directory contains OS-specific configurations (i.e. power-management configuration, X server configuration, daemon configurations, etc.)
/boot. This stores info for booting the system, such as kernel images, initrd images, bootloader configuration, etc.
/home. This stores your personal data. This is like C:\Documents and Settings\.
/root. This is the root user's home folder.
/sys, /proc. These contain info about the running state of the system.
/sbin. This contains basic programs intended for use by the superuser (i.e. root).
/var. This contains log files, caches, file locks, etc.
/dev. This contains device files. In Linux (and Unix in general), everything on the system is represented by a file. Hardware devices are represented by device files. For example, your hard drive, you sound card, your graphics card, the terminal emulator device that Konsole connects to, etc. are represented as files in this directory. On my system, for example, my disk is /dev/sda, my graphics card is /dev/nvidia0, etc.
/lib. This contains essential system libraries.
/media, /mnt. In Linux, you attach additional storage devices (i.e. USB sticks) to the system by mounting them onto an empty directory. These directories can be anywhere, but are traditionally stored in these directories. For example, on my system /mnt/usbstick is usually an empty directory, but when I plug in my USB stick (it will automatically be mounted), this directory will contain everything on my USB stick. When I unmount (i.e. click "Safely remove hardware") the stick, this directory will become empty. This is sort of like how in Windows a new letter drive (i.e. E
will appear on the system when you plug it in, and when you remove it the drive disappears.
/tmp. This contains temporary files that are erased every time the system reboots.
Hope this helps!
