From virtual machines to dual-system networking, ubuntu has a one-week experience.

I have been learning the linux operating system for the past few weeks. I copied a ubuntu image file from my friend last Sunday. I tried it on Monday with a virtual machine for a day, and I couldn't wait to think about it again the next day. 1. Let's take a look at ubuntu's most exciting 3d effects and 2. Because running a virtual machine consumes cpu, the speed is greatly affected.

Just do it. Is it from the hard disk? Or a dial? I have never tried the hard disk. Although I had known it before, I still dismissed the idea of modifying the boot file. An empty disk costs 1 RMB. In case the system crashes, you can start it on a CD, which is relatively safe.

So run ones to burn a ubuntu8.10. first, delete the f disk from the disk management (in fact, as long as there is no important thing in it, it will also be formatted at that time ).

Dial Installation

Start the first practical drill with excitement: Adjust the bios, start from the optical drive, and install it step by step as prompted. when partitioning, select manual partitioning, and then select the empty disk, and then create a new partition. Considering that my memory is 1 GB, I allocated 1 GB of memory to swap (I think it is a waste, because I generally do not use sleep ). The other 15g versions have ex3 for/format (as if ubuntu9.04 uses ex4 ). I didn't mount/home, because I don't have any important files in linux (the system can be remounted if the file is divided into/home without losing data ). Then, start automatic installation as prompted. When the Progress reaches 32 percent, it will be stuck. I have heard of it before, and the CD will be suspended. No way, please wait! Suddenly, a prompt is displayed, indicating that there is something wrong with the CD. Please select a slow burning mode. Okay! This CD is a waste. Take it and give it away! The image file in it should be good, but reading is faulty. The second time I learned the lesson, I learned it from my mind, and then I will not repeat it here-the installation is successful!

Use sudo passwd root to set the root password. When you input commands, you are used to adding directories using tap. Sometimes a long string of characters is really annoying.

Graphics card driver

When I couldn't wait to see the special effects, I suddenly noticed that the video card and the unlimited NIC Driver were not supported. My God! I have to find the driver again, so I can search for my linux driver on Google. Pay attention to the number of operating systems. First, enter the text mode. Run the command:/etc/init. d/MCM stop to disable the x mode, and then install the command. Look at the jelly-like dialog box (this metaphor seems to be a shame, but I like it), don't mention how happy it is. You also need to install software for 3d effects.

Networking

For the reason that the school is using the drcomclient local network, I found the drcom-1.4.8.1.tar, decompress the package, and install it (some need to install gcc). Run the command: make and run the command: make install. The subsequent configuration problems waste me a whole afternoon. Follow the prompts to modify the file. Command: gedit/etc/drcom. conf. I entered the username and password, Intranet range, dns server, and login server according to xp. For the remaining default values, enter drcomd on the terminal to display the third line of error. Maybe eth0 is not connected yet, sure enough, there are two display overlapping icons in the upper right of the panel with a logo indicating no network connection. Select Edit eth0. select mont, fill in the IP address, subnet mask, default gateway and dns server, and click OK to save. At this time, if the OK button is gray, it may be because you have filled in the mac address in advance and cleared the mac address (I don't know why, I tried it for a while ). If you log on to the terminal again with confidence, The sudo drcomd will display Row 3 errors. It should be because the Intranet range is incorrect. Simply delete all four intranets, leaving only their own IP addresses and subnet masks. Drcomd again, and then drcomc login, it shows that the connection fails. size = 5. I thought it was wrong to fill in the password! Change Password everything OK!

Supplement the eth0 connection process, tried for half a day to get it done: Choose wirde-eth0-edit-ipv4 settings -- method manual fill, Address: IP Address, netmask: Subnet Mask, gateway: default gateway, and dns server,.
