Info and help for HP TX2500 Series

[Favux]

Sorry farmercyst,

I should have asked if you had tried the old hot plug commands after a suspend. First ctrl-alt-F1 and then ctrl-alt-F7. See if that gives you your stylus and eraser calibration back.

[farmercyst]

Favux,

And I assume you made sure libhal1-dev wasn't installed when you compiled, correct? It shouldn't be installed by default anyway.

yes, i made sure libhal1-dev wasn't installed when i compiled 0.8.3-2.

And are you saying without touch in xorg.conf you are getting reaction to your finger, just not very well calibrated?

yes, thats correct.

It sounds like when you are resuming from suspend and X is restarting /home/username/.xinitrc isn't being run.

well now that you say that, i remember that i didnt set .xinitrc because it was calibrated close enough with my old xorg.

Breaking news. Please see post #104 here: http://ubuntuforums.org/showthread.p...038949&page=11 This should get Jaunty working for you. I hope!

thats exciting, im going to try this when i get home tonight!

Hi tannalv,

The following may help answer your question as to why it seems like acpi is being deprecated.

From Bryce Harrington at http://www2.bryceharrington.org:8080/drupal/node/63


Would another way to phrase your question be: Why are they moving thermal support away from acpi to the kernel? So it seems it has to do with the move to HAL (hardware abstraction layer)/dBUS & pmutils which will be supplanted by DeviceKit (which missed Jaunty but will be in Karmic, 9.10) which will be subsumed into udev-extras. The time line I think goes something like this. In April last year the lead HAL dev. (Red Hat/Fedora?) decided HAL was a dead end and then announced DeviceKit. Then within the last month he announced the last version of DeviceKit and that it was going to become udev-extras.

Hope this helps fill some of it in. I'm sure there's more involved I don't know about.

[Afief.h]

My keyboard seems to not work when I try to resume from suspend, stylus and touch do work for me.

Any ideas?

Hi Afief.h

I have a tx2590eo and the script in this link helped me with the same problems. (and I'm using Ubuntu 9.04 now)

Okay, I finally read up on how pm-utils works, 
and here is a solution that should work with Hardy.

Create the following file: sudo nano /etc/pm/sleep.d/25i8042

Code:

#!/bin/bash

case "$1" in
	hibernate|suspend)
		# Unbind the AT keyboard interface.
		if [ -f /sys/bus/platform/drivers/i8042/unbind ]; then
			echo -n "i8042" > /sys/bus/platform/drivers/i8042/unbind
		fi
		;;
	thaw|resume) 
		# Rebind the AT keyboard interface.
		if [ -f /sys/bus/platform/drivers/i8042/bind ]; then
			echo -n "i8042" > /sys/bus/platform/drivers/i8042/bind
		fi
		;;
	*)
		;;
esac

exit $?

Make sure this file is executable. There is no need to reboot your computer
 - your next suspend should work.
Please let me know if this works for anyone else.

[Afief.h]

Now I have a keyboard after suspend but no mouse(touchpad) but the wacom works so I can use that as a mouse(for now)


Do you know what I should read on so I can understand what that script did and apply it to my touchpad as well?

[martinjochimsen]

Sorry, but I have NO idea what anything means in the script. It just worked!
Strange about the mouse though. What kind of laptop do you have? Maybe there is a function that have locked the mouse? (fn+f1-12)

As mentioned here adding i8042.reset to grub is wat worked best for me (tx2510us):

$ sudo gedit /boot/grub/menu.lst

Find this line:
# kopt=root=UUID***************** ro
Change to this (leave the # at the beginning!):
# kopt=root=UUID***************** ro i8042.reset
save and close

$ sudo update-grub
then reboot...

hi marranzano, i've tried doing what you mentioned to solve the suspend issue, and though it worked, i lost my wifi ip gathering abilities in the process any ideas why?
i'm gonna try the script on /etc/pm/sleep.d now, let's see if that works..

this is ridiculous. i tried the script and not only i had just the keyboard as Afief.h, but i also lost my wifi connection and after 10 seconds the keyboard stopped working :/
oh well..
