Installing Ubuntu 8.04 (Hardy Heron) on a ThinkPad T30
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 depends on having a Cisco Aironet Wireless 802.11b card installed in the 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:
modules.alias:#alias aes padlock_aes modules.alias:#alias aes geode_aes
korgman: A nicer approach is to blacklist the modules, because in the first update those comments will gone ;)
echo "blacklist padlock-aes" >> /etc/modprobe.d/blacklist echo "blacklist geode-aes" >> /etc/modprobe.d/blacklist
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:
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
Interestingly, this causes the following message to appear in /var/log/Xorg.0.log
(WW) RADEON(0): Option "RightOf" is not used
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:
$ 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.

Despite what is suggested by the X log output, the touchpad does work. The right side of the touchpad functions as a scroll control.
The last release corrects an old bug: sound volume keys don't change the software mixer.
Another problem that can happen is that the sound card device won't be recognized. ALSA will report no sound cards found. Although seemingly unrelated, the removal of padlock_aes module helped clear this up. In the file /lib/modules/2.6.24-19/modules.alias make sure these two lines are commented out, then reboot.
#alias aes padlock_aes #alias aes geode_aes
For the record, the ALSA module is snd-intel8x0.
There are a couple of annoying problems with suspend and resume:
- The LCD backlight stays on during suspend
- No sound after resume
To force the LCD backlight to turn off when suspending, first ensure radeontool is installed:
sudo apt-get install radeontool
Then, as root, save this script in /etc/pm/sleep.d/21radeon:
#!/bin/sh case "$1" in suspend|hibernate) /usr/sbin/radeontool dac off /usr/sbin/radeontool light off ;; esac
You must set the script executable:
sudo chmod +x /etc/pm/sleep.d/21radeon
Sound after resume
To fix sound after resume, as root, save this script in /etc/pm/sleep.d/99sound:
#!/bin/sh case "$1" in resume|thaw) /etc/init.d/alsa-utils restart ;; esac
You must set the script executable:
sudo chmod +x /etc/pm/sleep.d/99sound
