My computer is locking up while I'm using the trackpad. It seems to occur most after I install graphics drivers on a fresh install of ubuntu. It has occured once on a fresh install of 14.10. It also occurs in 14.04 after I install graphic drivers. I can't use ubuntu like this, because it's causing all sorts of problems. Does anyone know a fix?

I'm running an asus republic of gamers g750jm with a gtx860m graphics card in it. I don't believe I'm the only one with this problem and I found a solution that I believe works but it disables my trackpad's two-finger scroll. The page is here: http://www.hackingnotcracking.com/?p=112 does anyone know how to avoid disabling the two finger scroll so I can test and see if this page's suggestion fixes my problem?

UPDATE: I did test that pages solutions they didn't work. I still can't use Ubuntu unless I choose to not install drivers for my gtx860m,... so now I just don't install graphic drivers now.

UPDATE: I am following the instructions laid out here: Ubuntu and ASUS G750JM, GTX860M / Nvidia problems and running into this problem. Any advice or input may help the cause.

Still looking for a solution, I even set a bounty and nothing. I'd open a bug ticket on it but I'm using edgers drivers. When I try to install the nvidia drivers from their website lightdm won't even boot.

  • In order to even begin helping, we're going to need some more information such as computer model, graphics card, touchpad model, etc. Bascially, we need more specifics. – Chuck R Nov 2 '14 at 18:46
  • Okay I added some more info @githlar – Daniel Nov 2 '14 at 20:36

    Since this would seem to be a Nouveau-specific problem, I would recommend installing the drivers from Geforce.com (especially since you are using a new NVIDIA card that isn't supported by the Nouveau drivers, no 3D acceleration for Tesla-based cards) and see if that helps to resolve your issue. – Chuck R Nov 2 '14 at 21:13
  • I've already been through that, they never would work I ended up having to solve the issue myself by doing askubuntu.com/questions/519372/… the stuff listed on that page... blacklisting the nouveau drivers isn't really necessary however. But after I do that stuff is when I experience the problem. @githlar – Daniel Nov 2 '14 at 21:34
  • Yep, that is essentially doing the same thing as installing the drivers from the Geforce site (Xorg Edgers has the most updated drivers -- just like the site), except that Bumblebee was installed as well for hybrid Intel HD/Nvidia configurations. – Chuck R Nov 3 '14 at 1:24

I was experiencing the same problems on a laptop with GTX 860M, Ubuntu 14.04. I had the mouse cursor freeze (actually it must have been lightdm locking up) due to having the wrong graphics driver active. I had tried with the one from GeForce.com without any luck. Here is how I eventually made it work:

First, make sure drivers from GeForce.com are uninstalled (if you have them installed, run the installation file again with the --uninstall flag).

Then, update your sources, purge any packages with reference to nvidia and bumblebee. Install nvidia-prime and nvidia-340. Run nvidia-xconfig and reboot. Here are the commands:

sudo apt-get update
sudo apt-get purge bumblebee*
sudo apt-get purge nvidia*
sudo apt-get install nvidia-prime
sudo apt-get install nvidia-340
sudo nvidia-xconfig
sudo reboot

Note: if you have trouble using the graphical interface, press [Ctrl]+[Alt]+[F1] and log in on the first cli interface. If needed, enter sudo service lightdm stop to stop the graphical interface before running the above commands.

  • This is exactly what I've been doing. – Daniel Nov 3 '14 at 20:16
  • Actually this is not exactly what I've been doing, but you see, as soon as I install nvidia-340 the problems start occuring. I was using bumblebee and nvidia-340... having these problems. – Daniel Nov 5 '14 at 5:13
  • I also got problems using bumblebee. Have you tried the combo nvidia-prime and nvidia-340 (or nvidia-current)? – Alasjo Nov 5 '14 at 13:37
  • I just tried it- didn't work either – Daniel Nov 5 '14 at 15:34

Turn on trackpad while using keyboard in settings, I found this answer online and so far it has resolved the problem
