Installation of the Ubuntu10.10 official version of the problem, including the Broken network

A few questions came:
1.SIS Motherboard PC Installation Ubuntu10.10 Official edition, will not be able to access the installation interface.
Workaround:
In the previous article on the installation of Ubuntu10.10 official version of a problem and the solution has been said
When you enter the boot interface, you will see the following startup items:

Ubuntu, with Linux 2.6.35-22-generic

Ubuntu, with Linux 2.6.35-22-generic (recovery mode)

Memory Test (memtest86+)

Memory Test (memtest86+, serial console 115200)

Windows 7 (loader) (ON/DEV/SDA1)

The first is the normal start Ubuntu, the second is Safe mode, first move the cursor to the normal boot, press E to enter as follows:

In the/boot/vmlinuz-2.6.35-22-generic Root=uuid=cb432b6a-e74e-4d81-93fa-9909b2557194ro single after a space plus as the three options that were canceled: acpi= Off,noapic,nolapic

Then press Ctrl+x to get into the system. The following method is different from what was said before and then explained

2.UBUNTU10.10 official version, not normal shutdown, this also needs to be modified, according to the changes, the boot into the system problem is resolved, I have tried. Modified as follows:

1. Open the terminal, enter

sudo gedit/etc/modules

Return at the last line of a file, add another line

APM Power_off=1

Save, close
2. In the midrange input

sudo gedit/etc/rc0.d/s90halt

Locate the following code:

hddown= "-H"
If Grep-qs ' ^md.*active '
/proc/mdstat
Then
Hddown= ""
Fi
And
Netdown= "I."
If ["$NETDOWN" = "no"];
Then
Netdown= ""
Fi

Comment out these two pieces of code as follows:

# hddown= "-H"
# if Grep-qs ' ^md.*active '
/proc/mdstat
# Then
# hddown= ""
# fi
And also
# netdown= "-i"
# if [' $NETDOWN ' = ' no ']; Then
# netdown= ""
# fi

Save, exit
3. In the midrange input:

sudo gedit/etc/default/grub

Found it

Grub_cmdline_linux= ""

Modified into:

grub_cmdline_linux= "NOACPI acpi=off acpi=force APM power_off=1"


Save, exit
Enter again at the midrange:

sudo update-grub

You can shut down and turn on the computer normally.

3. Internet often automatically break the problem of network, modified as follows: sudo gedit/etc/ppp/options

Find Lcp-echo-interval and lcp-echo-failure, and make these two numbers bigger, like I wrote a 3000 and a 400 straight, and I haven't broken the line since this afternoon.

4. The right key does not have the terminal, this question also incidentally writes:
sudo apt-get install nautilus-open-terminal

It's OK.

5. With regard to the ECLIPSE+CDT question, this let me really toss for a while.

There is nothing wrong with installing eclipse: sudo apt-get install eclipse-platform is done, ubuntu10.10 installed eclipse is 3.5.2, so the CDT corresponds to http:// Download.eclipse.org/tools/cdt/releases/galileo

Then enter eclipse, select Help->install new software, after adding the above URL, all the way next, will find failure

Solution: There are a few dependencies that could not be installed, so after canceling the few, next time it succeeded. As for those, I forgot to try it one by one, and it won't take long.

6. Ubuntu Network source download too slow:

Backup software Source: sudo cp/etc/apt/sources.list/etc/apt/sources.list

Open Sources.list:sudo Gedit/etc/apt/sources.list

The original Deb beginning of the contents of all removed, the network state, the following source a group of a group of handcuffs into (ensure that only one group each time), specific also need not be so heroic, you can draw on the recommendations of the next to try some of them. Each send in a group, Ctrl+s save, start the Update Manager, click "Check Update", then Ubuntu will download from the source you set up the list of software, you then observe the download speed, if soon, choose him. (Reference: I use Xuzhou Campus Network telecommunications, Education Network connection when Xiamen University very fast).

In addition, can not completely follow the copy of these, Ubuntu each stable version has a code, such as 8.04 called hardy,9.10 called karmic,10.04 called lucid,10.10 Maverick, some software sources in order to differentiate the version has this code, Available network sources are as follows, if it is telecommunications, recommend using Cn99:
