My girlfriend has an HP dv6000. In ubuntu 10.10 32bit i use the synaptics on it and all is good but when i disable it and enable it the problem starts. When booting the problem was that the synaptics was not working i then made the changes describe in EDIT 2. Now when i press the disable button in the synaptics touchpad it disables the mouse AND the keyboard. After enabled the Keyboard keys and Mouse clicks do not work. If i click on the panel below, for example the Applications, Places or System buttons the focus gets stuck there forever. I can open nautilus by clicking on it but i can not use the menus, the ALT+F2 function, see the wireless connections, lower the sound through the panel, etc..
Here comes the weird part. If i press CTRL+ALT+F1 (or any other tty for that matter) and then come back to CTRL+ALT+F7 where the gui is everything works perfect again. This started about a week ago but she told me right now. i checked dmesg which is for sometime now throwing some warnings about Skipping EDID probe do to cached edid but for what i could find out this did not create the problem in the start.
NOTE: I do not need to login when i do CTRL+ALT+F1 i just need to change to another tty then come back to F7.
What could be causing this problem?
EDIT 1 - After a couple of tests, this is what happens or is added to /var/log/syslog when i change to CTRL+ALT+F1 after the problem starts:
Jan 4 22:33:07 mary acpid: client 1234[0:0] has disconnected
Jan 4 22:33:07 mary acpid: client connected from 1234[0:0]
Jan 4 22:33:07 mary acpid: 1 client rule loaded
EDIT 2 - I have solved the synaptics when booting up (the problem was that it was not working at all) by adding this to rc.local:
modprobe psmouse proto=imps
EDIT 3 - Found two articles about the same problem: http://ubuntuforums.org/showthread.php?t=1470117 - / - https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+bug/549727/+index?comments=all
EDIT 4 - After some more tests i found maybe the problem (Not 100% sure). When i click on the disable button in the synaptics touchpad it makes a change in the file:
and it makes FALSE the following line:
<entry name="touchpad_enabled" mtime="1294200522" type="bool" value="false"/>
But when i enable it again it does not change the file. It leaves it FALSE that is why i have to do CTRL+ALT+F1 to activate it somehow.
EDIT 5 - I made a file called touchpad.conf in /etc/modprobe.d with the following line: options psmouse proto=imps To test. It still did not work.
UPDATE: The following HP Models are affected by this problem on Ubuntu 10.10:
