Lucid Lynx (Ubuntu 10.04 LTS 64-bit) Suspend/Resume Solution

Lucid Lynx would lock up when resuming from a suspend on my Dell Studio 1555 notebook computer. Finally it seems to be solved in AMD's Catalyst version 10.6 driver set.

But then I discovered I couldn't eject an optical disc, so I had to add nomodeset to my Grub line.

sudo nano -w /etc/default/grub

Find the line that reads:

GRUB_CMDLINE_LINUX=""

and put nomodeset between the quotes. Then save it, exit, and run:

sudo update-grub

Adjust Synaptics Touchpad in Lucid Lynx

Until Lucid Lynx, HAL was used to control certain settings. For example, to adjust the Synaptics Touchpad on a laptop, settings could be put into /etc/hal/fdi/policy/11-x11-synaptics.fdi (see my previous post). However, HAL was removed in Lucid. How, then, does one make these adjustments to a Synaptics Touchpad? ... by using xinput.

I created a folder named .synaptics in my home directory (/home/myuser/). Then I made a text file named touchpad_adjustments.sh (filename doesn't really matter) which contained the following (the xinput lines beginning with # are adjustments I left in that I may want to easily enable later): (SEE UPDATE AT END OF THIS POST TO VIEW MOST RECENT ADJUSTMENT FILE I USE.)

#!/bin/bash
#
# list of synaptics device properties http://www.x.org/archive/X11R7.5/doc/man/man4/synaptics.4.html#sect4

#

# xinput --set-prop --type=int --format=8 "SynPS/2 Synaptics TouchPad" "Synaptics Circular Scrolling" 1
# xinput --set-prop --type=int --format=8 "SynPS/2 Synaptics TouchPad" "Synaptics Circular Scrolling Trigger" 3

exit

Then I made sure it had execute permissions by running:

chmod ug+x /home/myuser/.synaptics/touchpad_adjustments.sh

After that, to make sure it ran every time I started a session, I went to System > Preferences > Startup Applications and chose "Add," then gave it this filename for the command.

Update: The most current version of touchpad adjustment file I use is:
