[Bug 1035208] Re: touchpad stops working (moving the pointer doesn't work)
OS: Kubuntu 12.04 HW: clevo p150em notebook - don't know the touchpad manufacturer I have exactly the same problem with my clevo p150em notebook. (no movement, scrolling still possible) It's quite frustrating. It happened several time while I was watching youtube videos, but the reason for this could be that I did spend a lot of time on youtube... I have synaptiks enabled (the tool to control the touchpad). I enabled the disable touchpad for 1sec after button pressed option and the disable touchpad when mouse is present. I don't know how to force this bug. Maybe some dev has to work for 1-2h without a mouse, maybe then the bug will occure. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1035208 Title: touchpad stops working (moving the pointer doesn't work) To manage notifications about this bug go to: https://bugs.launchpad.net/ac100/+bug/1035208/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1035208] Re: touchpad stops working (moving the pointer doesn't work)
Hi there. I believe I experience the same problem. Here is what happened: I clicked on a tab in Chromium, and it got stuck with a right-click menu. I thought it was X and I had to reboot, but I used a USB mouse instead, and everything works fine. The touchpad still doesn't work, the pointer doesn't move. However, I can scroll normally (right side) and use the touchpad buttons normally. Funny thing though: clicking with the touchpad (i.e. touching it once) gives the same result as a right-click. Should this be a duplicate of Bug #830099?

@Ivan, the nvec message look normal. Btw, you can get rid of the page allocation failure message by increasing the min_free_kbytes in /proc/something, but this is neither critical nor tp related.

[Bug 1035208] Re: touchpad stops working (moving the pointer doesn't work)
Today I noticed that although the touchpad appeared to be not working completely (no pointer movements, and the pointer in X disappeared), it must still be working physically because there was a reaction for the scrolling gesture (gliding up and down at the right side of the touchpad caused scrolling the window contents up and down, as usually). So this must be some software problem, perhaps even of a higher level driver (X.org driver) which is responsible for interpreting the gestures (touching the touchpad) as either movements or scrolling... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1035208 Title: touchpad stops working (moving the pointer doesn't work) To manage notifications about this bug go to: https://bugs.launchpad.net/ac100/+bug/1035208/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

At least, in the *tail* of overall dmesg that I have attached (which is some while after this issue occured) there are no nvec-related messages.

It just happened right now. I've saved dmesg output and the X's log. (Attaching them.) There are no nvec messages in dmesg. But there are two ec messages. Are they important? I've checked once again the behavior of the touchpad when this happens: movements don't work, but scrolling doe work (at the right side of the pad with a single finger), clicking does work (by hitting the pad, or with the buttons underneath -- both work). I tried to press F9: this turned the tocuhpad competely off. Then I pressed F9 once again: and this resulted in the same errpneous situation: movements don't work, other things do work (scrolling, hitting). So it's not a matter of F9. And it's not matter of complete disconnection.
