Several minor problems encountered when installing Ubuntu11.10

I have been working in Linux for a while. Today I saw the release of Ubuntu11.10Alpha2, so I just downloaded it and tried it. This machine is basically a laboratory. The original ubuntu was installed on the hard disk. (1) Press c in grub to enter the command mode (2) Set and boot setroot = (hd0, msdos1) linux (hd0, msdos1)/casper/vmlinuzboot = casp according to your computer situation

I have been working in Linux for a while. Today I saw the release of Ubuntu 11.10 Alpha2, so I just downloaded it and tried it. This machine is basically a laboratory.

Because Ubuntu 11.04 was originally available, you can install it directly on the hard disk.
(1) Press c under grub to enter the command mode
(2) Set guidance based on your computer
Set root = (hd0, msdos1)
Linux (hd0, msdos1)/casper/vmlinuz boot = casper iso-scan/filename = u. iso # name changed by yourself for convenience
Initrd (hd0, msdos1)/casper/initrd. lz
Boot
Note that the two files under casper need to be extracted from iso. You can use mount-o loop... to mount iso to a directory for extraction.
(3) After the startup is complete, double-click the installation. The installation will fail. So I deregistered it, but the problem came out. After I deregistered it, there was a wallpaper and nothing went wrong. Therefore, log on to the console:/etc/init. d/TPD start | stop. The result does not contain the target group. Previously, we used lightdm to replace it, but we have never seen lightdm.
Because lightdm won't do it either, there is no way, so restart and then install it.
(4) the installation is successful.

The installation sequence is similar to that of 11.04. There are several options when you log on. I want to give it a try, So I logged out and ended up with a wallpaper.
Go to the console: control + alt + f1
I checked the process: ps-A | grep lightdm.
After killing them, the graphic interface is gone. Enter lightdm start to display the logon interface. Log out again !!!

Because lightdm start is used in the console, control + c is directly interrupted and the graphic interface is no longer available. I use

Service lightdm start
Service lightdm stop
After testing, it is more convenient to use this tool. Although it is troublesome, you don't have to restart the computer.

The overall feeling is still good. I remember the total error rate from 10.10 to 11.04. Now this error rate (on my machine) is significantly reduced.
