Fixed Issues

ACPI

Bug description (Declared on LauchPad : #147560])

Facts: Laptop Chipset: Intel Santa Rosa 965PM BIOS support: PnP, Supports ACPI 1.0b og 2.0 BIOS flashed to version 3.0E (the latest version) Ubuntu version: Gutsy Gibbon 7.10

The bug is described as the following: When the AC cable is plugged in then sometimes Ubuntu claims that the AC cable is unplugged and the laptop lid light is by result of this dampen. And sometimes on battery with AC cable unplugged then Ubuntu claims that the AC cable is plugged in.

Possible fix: Add ec_intr=0 boot option to /boot/grub/menu.lst for the kernel you are using and reboot.

In Hardy, ec_intr boot option is no longer available. acpi=noirq boot option can be used instead. However, this fix disables brightness function keys.

Sound

The sound is nearly working properly with the initial installation.

Problem : Internal Speakers are not muted when headphones or external speakers are plugged in.

To Fix this issue, Add the following line at the end of the /etc/modprobe.d/alsa-base

sudo gedit /etc/modprobe.d/alsa-base

and add the following line at the end this files :

options snd-hda-intel model=targa-dig

PulseAudio

In Hardy it is recommeded to fix PulseAudio's behaviour a little bit. Guide to that can be found from http://ubuntuforums.org/showthread.php?t=789578

Webcam

Work using USB Video Class : [http://linux-uvc.berlios.de/] and pressing P2 button

Instruction for installation : You need to install a few packages to compile the source

sudo apt-get install build-essential kernel-headers make gcc subversion

then get the source

svn checkout svn://svn.berlios.de/linux-uvc/linux-uvc/trunk linux-uvc
cd linux-uvc

Then you have to edit the file Makefile

gedit Makefile

and replace the following line

INSTALL_MOD_DIR := usb/media

by

INSTALL_MOD_DIR := kernel/ubuntu/media/usbvideo

Save and then run

make && sudo make install

Then don't forget to press the P2 button to activate the Webcam !

And the webcam should work !

Dual Screen

Remark : Due to limitation of the GMA 965 card, the dual screen cannot be fully working with 3D Desktop like Compiz. (Limiation of the total size of the screen to 2048*2048 px)

However, dual screen is properly working with xrandr 1.2 if your do not activate the Compiz Desktop

For the MSI PR200 precise case, a solution "out of the box" with external LCD 19" screen, or projector (1280*1024), is given by the following instructions :

1. Do a backup of your xorg.conf (if there was any problem, then you can recover our previous configuration)

sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf_safe

2. open the /etc/X11/xorg.conf

gksudo gedit /etc/X11/xorg.conf

Replace the "Device", "Monitor", "Screen" and "ServerLayout" Sections of your previous /etc/X11/xorg.conf with the following lines

Section "Device"
        Identifier      "Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller"
        Driver          "intel"
        BusID           "PCI:0:2:0"
        Option          "MonitorLayout" "CRT,LFP"
        Option          "Clone" "Off"
EndSection

Section "Monitor"
        Identifier      "Philips 170S"
        Option          "DPMS"
EndSection

Section "Screen"
        Identifier      "Default Screen"
        Device          "Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller"
        Monitor         "Philips 170S"
        DefaultDepth    24
        SubSection "Display"
                Modes           "1280x1024" "1024x768" "832x624" "800x600" "720x400" "640x480"
                Virtual 2624 2048
        EndSubSection
EndSection

Section "ServerLayout"
        Identifier      "Default Layout"
        Screen          "Default Screen"
        InputDevice     "Generic Keyboard"
        InputDevice     "Configured Mouse"

EndSection

3. Restart the X server

sudo /etc/init.d/gdm restart

Without any other manipulation, the external screen should be a cloned verion of the laptop screen.

4. Then to launch the dual screen with External Screen (VGA) on the left of Laptop Screen (LVDS) type the folling comand in a command line :

xrandr --output VGA --left-of LVDS
