There's a fix for Ubuntu 11.04, 11.10 (Unity) as well. Read to the end.
The Synaptic Touchpad driver of touch-pad is installed, and it's Recognized. The problem is sometimes it gets disabled for no reason. Subash's Touchpad didn't work just after the fresh install, forcing him to reinstall again, as the reason was unclear at the moment. Later we found the problem and the fix.
What we have to do is enable the touchpad by setting the touchpad_enabled property to true. Here's the command to do it in one step.
gconftool --type Boolean --set /desktop/gnome/peripherals/touchpad/touchpad_enabled trueThis changes the touchpad_enabled property to true in ~/.gconf/desktop/gnome/peripherals/touchpad/%gconf.xml file. This will fix the issue.
Alternative to above, you may edit the file manually and restart gnome. Change the touchpad_enabled property to true (see screenshot), and enter following command in terminal:
killall gnome-session
As I've said, this has fixed the issue in my laptop, HP DV-5, Synaptic Touchpad, Ubuntu 10.04. Share the model of your laptop as well if this fix worked for you too.
The above solution is for GNOME, and probably won't work on Unity Desktop Environment (ie. Ubuntu 11.04, 11.10). For that, try the following.
unity --replace
sudo modprobe -r psmouse && sudo modprobe psmouse
Does this fix work for you? I haven't extensively checked this. So, value your feedback.
UPDATE 1: After the touchpad issue, it's quite difficult to navigate. So, I created a simple script for it. Save it to your home(~/) folder. Then, you can run it by following command from terminal.
sh ~/touchpad-fix.shDownload touchpad-fix.sh
(You can get the terminal by pressing ALT+F2. Type "gnome-terminal" without quotes and press Enter. Or just press Ctrl + Alt + T)
UPDATE 2: Sometimes, when touchpad disable button is pressed, Keyboard starts to not work. But, still (fortunately) some key combinations works. The reason for keyboard not functioning is unknown for me, but there's a workaround for this problem. The work around which fixed this keyboard issue is the following.
That is, go to console tty1 and come back! Strange, but it does work.
- Press CTRL+ALT+F1 (This will bring you out of X Window for a moment)
- Then, CTRL+ALT+F7 (This brings back the X )
yes, i also have the same problem. once i disable the touchpad, i can't re-enable. :'(
ReplyDelete@ශාකුන්තල Yes. that too an issue. Does entering the above code fixes the issue of yours?
ReplyDeleteSome times I copy and paste the above command to the terminal using keyboard shortcuts and it works! :-)

ReplyDeletedon't do spiderman stuff with keyboard. just prepare a one-line bash script and call it using Alt+F2
