Installing Ubuntu 8.04 (Hardy Heron) on a ThinkPad T30

Djc: Add suspend/resume fixes

= Slow boot =
This is a problem which afflicted at least one T30 machine when the last beta of Ubuntu 8.04 (Hardy Heron) was installed on it. Another user reports not encountering this problem when installing the release version of Hardy; however, it probably depends on having a [[Cisco Aironet Wireless 802.11b]] card installed in the [[miniPCI slot|mini-PCI slot]].

At first the {{T30}} took three minutes to boot and "ps" showed that several modprobe commands were hung in "D" state. The workaround was to comment out two lines in /lib/modules/2.6.24-16-generic/modules.alias:

<pre>
modules.alias:#alias aes padlock_aes
modules.alias:#alias aes geode_aes
</pre>

= X =
== Running dual-head ==
I connect various external monitors on the DVI port of the port expander. In order to spread one desktop over the laptop monitor (1400 x 1050) and the external monitor (e.g., a Samsung 1680 x 1050) I had to edit xorg.conf:
<pre>
Section "Module"
Load "glx"
Load "GLcore"
Load "dri"
Load "v4l"
EndSection

Section "InputDevice"
Identifier "Generic Keyboard"
Driver "kbd"
Option "XkbRules" "xorg"
Option "XkbModel" "pc105"
Option "XkbLayout" "us"
EndSection

Section "InputDevice"
Identifier "Configured Mouse"
Driver "mouse"
EndSection

Section "InputDevice"
Identifier "Synaptics Touchpad"
Driver "synaptics"
Option "SendCoreEvents" "true"
Option "Device" "/dev/psaux"
Option "Protocol" "auto-dev"
Option "HorizEdgeScroll" "0"
EndSection

Section "Device"
Identifier "Configured Video Device"
Boardname "ATI Rage 128 Mobility"
Busid "PCI:1:0:0"
Driver "ati"
Vendorname "ATI"
EndSection

Section "Monitor"
Identifier "LVDS"
EndSection

Section "Monitor"
Identifier "DVI-0"
Option "RightOf" "LVDS"
EndSection

Section "Screen"
Identifier "Default Screen"
Device "Configured Video Device"
Monitor "LVDS"
Monitor "DVI-0"
Defaultdepth 24
SubSection "Display"
Depth 24
Virtual 3080 1050
EndSubSection
EndSection

Section "ServerLayout"
Identifier "Default Layout"
Screen "Default Screen"
Inputdevice "Synaptics Touchpad"
EndSection

Section "ServerFlags"
EndSection
</pre>

Interestingly, this causes the following message to appear in /var/log/Xorg.0.log
<pre>
(WW) RADEON(0): Option "RightOf" is not used
</pre>
but this is not true, since omitting this option (from the Monitor section for DVI-0) casues X to start in clone mode instead.

The other errors and warnings in the log file are:
<pre>
$ grep [WE][WE] /var/log/Xorg.0.log
(WW) warning, (EE) error, (NI) not implemented, (??) unknown.
(WW) The directory "/usr/share/fonts/X11/cyrillic" does not exist.

</pre>

== Synaptics Touchpad ==
Despite what is suggested by the X log output, the touchpad does work. The right side of the touchpad functions as a scroll control.

= Sound =
The last release corrects an old bug: sound volume keys don't change the general sound volume.

= Suspend/Resume =
There are a couple of annoying problems with suspend and resume:
* The LCD backlight stays on during suspend
* No sound after resume

== LCD Backlight ==
To force the LCD backlight to turn off when suspending, first ensure radeontool is installed:
<pre>sudo apt-get install radeontool</pre>

Then, as root, save this script in /etc/pm/sleep.d/21radeon:
<pre>
#!/bin/sh

case "$1" in
suspend|hibernate)
/usr/sbin/radeontool dac off
/usr/sbin/radeontool light off
;;
esac
</pre>

You must set the script executable:
<pre>sudo chmod +x /etc/pm/sleep.d/21radeon</pre>

== Sound after resume ==
To fix sound after resume, as root, save this script in /etc/pm/sleep.d/99sound:
<pre>
#!/bin/sh

case "$1" in
resume|thaw)
/etc/init.d/alsa-utils restart
;;
esac
</pre>

You must set the script executable:
<pre>sudo chmod +x /etc/pm/sleep.d/99sound</pre>
