I finally successfully converted my Sony waio p27h to Ubuntu 10.4.

Speed Perception during use: Ubuntu> maxos >>>> win7/XP> Vista (note> Number of vertices)

 

It is not necessary to mention the bad vista of the original system. Later, XP and win7 were modified. Although the drivers/functions were perfect, the speed of use was not flattering.

In the meantime, although Mac OS is installed, some drivers cannot work, Ubuntu has been installed twice, and the display and sleep work is not good.

 

Mac OS is not good, but it is not as good as Ubuntu to install Mac OS on non-Mac machines, especially on general screens.

It is very bad. If you want to use Mac OS, just buy an apple machine.

 

Therefore, we are still confused about ubuntu. Today we open several documents we have read before, mainly based on this document:

Https://wiki.ubuntu.com/HardwareSupportComponentsVideoCardsPoulsbo

 

Installing 10.04 first is still an old problem. Many people have reflected this. After setting it, the black screen cannot be entered after restarting.

So search again, see http://ubuntuforums.org/showthread.php? T = 1468975 posts, put 10.04

In combination with the 9.10 method, the display card can be perfectly driven:

 

9.10 video card setting process:

 

Sudo add-Apt-repository PPA: gma500/PPA & sudo apt-Get update

Sudo apt-Get install poulsbo-config poulsbo-driver-2d poulsbo-driver-3d PSB-firmware PSB-kernel-headers PSB-kernel-Source

 

Sudo gedit/etc/X11/Xorg. conf

Replace the content:

Section "device"
Identifier "gma500"
Driver "PSB"
Option "ignoreacpi" "true"
Option "migrationheuristic" "greedy"
Endsection

Section "dri"
Mode 0666
Endsection

 

Note that the content of/etc/X11/Xorg. conf after replacement is not append.

 

Sudo VI/etc/default/GRUB

Modify grub_cmdline_linux_default = "quiet Splash":

Grub_cmdline_linux_default = "quiet splash mem = 2000 MB nohz = off VGA = 0x367"

VGA = 0x367 is important.

 

Sudo Update-grub

Sudo reboot

After the restart, we can see that the original display is refreshed to 0 and now it is 60. Although there are no other settings, the screen is no longer very slow and smooth when it is pulled down.

 

 

After 9.10 is successfully installed, I want to see if 10.04 is also possible. I have created a 10.04 installation disk. After installation, I will repeat the above settings under 10.04 and OK.

The original by the https://wiki.ubuntu.com/HardwareSupportComponentsVideoCardsPoulsbo settings to restart the black screen, but now because

The content replaced by/etc/X11/Xorg. conf can be successfully driven. Although there is no setting option, it can run smoothly.

 

 

The difference between the 10.04 setting process and 9.10 is that

 

Sudo apt-Get install poulsbo-driver-2d poulsbo-driver-3d poulsbo-config, Not Installed

PSB-firmware PSB-kernel-headers PSB-kernel-Source

 

After solving the problem of display, I searched for the problem of sleep, which is very easy to solve:

Sudo apt-Get remove vbetool
Sudo apt-Get install uswsusp

Replace/usr/sbin/PM-suspend with the following content:

 

#---------------------------------------------------------------

#! /Bin/sh
# Remove WLAN modules
For m in 'lsmod | grep ath9k | awk' {print $1 }'';
Do
Rmmod $ m
Done
S2ram -- force
Modprobe ath9k

#-----------------------------------------------------------------

 

I performed the following operations for backup:

Sudo mV/usr/sbin/PM-suspend/usr/sbin/pm-suspend.bak

Sudo VI/usr/sbin/PM-Suspend

When I inserted the content into the storage disk and exited, I was unable to perform the operation successfully. I was prompted that I didn't have the permission to execute the operation:

Sudo chmod 711/usr/sbin/PM-Suspend

 

In fact, if you open and edit the original file, you will have the execution permission. In this way, the WLAN will not be disabled during sleep. You need to disable it manually and enable it manually during sleep.

 

 

I am very satisfied now. I want to help people who have the same problems with me,
