[nvidia-prime]Freeze while using touchpad

Bug Description

Using Asus N43SL laptop as an example, with nvidia-prime installed, so the dedicated NVIDIA graphics card (GT 540m) is in use, once in a while, my screen will freeze when I use my touchpad.


WORKAROUND: Uninstall nvidia-prime and use integrated graphics.

WORKAROUND: Do a VT switch via Ctrl+Alt+F1 then Ctrl+Alt+F7.

In the attached Xorg.0.log, you can see "synaptics: ETPS/2 Elantech Touchpad: touchpad found" each time I did a VT switch and regained control:

The following upstream report has a patch that addresses this issue:

Whatever is causing this, it can't possibly be the nvidia-prime package, since it only contains helper scripts.

I'm reassigning this to the nvidia driver.

Any changes with nvidia 331.20 drivers ?

To me, there are no changes when using 331.20, same issue.

@Daniel: any ideas?

NOTE: this happens with RandR offloading. (I can't reproduce it though)

Daniel Dadap (ddadap) wrote :

Sorry, I don't have any ideas. I don't think we've seen anything like this either; we'd probably need a machine that uses the same touchpad or touchpad driver.

If the Nouveau driver also supports the RandR 1.4 provider source capability, it might be an interesting experiment to configure PRIME with Nouveau -> modesetting to see if it's a generic interaction between the touchpad driver and RandR 1.4. Alternatively, it might be useful to attempt configuring an X screen on the Intel GPU using the modesetting driver and no offloading, to see if it's a general interaction between the touchpad driver and the modesetting X driver. That should be a lot easier to set up.

Or... another possibility would be to try configuring the offloading with the Intel driver as the provider output instead of the modesetting driver. I can't remember the specific problems we ended up having with the Intel driver that led us to recommend the modesetting driver in the README instead, but if the Intel driver works as an output for you, and the problem is due to an interaction between the modesetting and touchpad drivers, then this may be a way to avoid the problem.

These are all just wild guesses though; I don't have any good ideas as to why this might be happening.

I have exactly the same problem on Lenovo G700. If using GPU offloading and touch-pad it takes 5 to 120 s to experience a lock-up with that message in X-org log. Unexperienced user (not knowing about VT-switch) would think it's complete system freeze.

I'm having the same issues after upgrading to 13.10 and prime. The system locks most when accessing pull down menus Never happened under bumblebee but then again i was using 304 nvidia drivers. Also does the prime for 13.10 not have the extra menu in nvidia-settings to select PRIME Mode? discrete or Intel?

Same problem on ubuntu 13.10 and nvidia-prime (319 and 319-update).

Screen freeze randomly when using touch pad, and to fast "unfreeze" the screen I've to switch to console terminal (Ctrl+Alt+F1) and back to graphical console (Ctrl+Alt+F7)

Corollax (corollax) wrote :

Sorry, not sure how to edit my last comment: I'm using an GeForce 630M.

Not sure if this helps, but it's strictly a visual freeze. The system will recognize inputs after the "freeze" -- the screen just doesn't update until you switch back and forth from the virtual terminals.

Hopefully that will help you debug the problem.

I have created file /etc/modprobe.d/psmouse.conf with following entry:

options psmouse proto=imps

I have rebooted the notebook and had to increase pointer speed of trackpad under System settings > Mouse & Touchpad after reboot. So far I don't have any issues with trackpad freezing.

Default parameter proto for psmouse module is set to auto. The current value of the proto paramater of psmouse kernel module can be read from /sys/module/psmouse/parameters/proto file:

cat /sys/module/psmouse/parameters/proto

After creating /etc/modprobe.d/psmouse.conf file parameter is set to ImPS/2.

The idea for changing psmouse proto parameter came from https://answers.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+question/176273.

So the quick fix would be:
1.) Run following command from terminal:
echo "options psmouse proto=imps" | sudo tee /etc/modprobe.d/psmouse.conf >/dev/null

2.) Reboot the system or reload psmouse module from terminal with following commands:
sudo modprobe -r psmouse && sudo modprobe psmouse

3.) Increase the speed of pointer under System settings > Mouse & Touchpad

Can anyone else confirm this fix ?

Same issue here on Ubuntu 13.10 Nvidia GT 750M using nvidia-331 and nvidia-prime. The same issue doesn't happen when using #18 fix or using an external mouse. I also have a touchscreen (eGalax Inc. eGalaxTouch EXC7910-1023-12.00.00) - I wonder if that can cause the issue.

Regarding #18 fix, any idea if touchpad scrolling can be enabled (using a Synaptics touchpad here)? I would rather have scrolling - sure the freezes are annoying but Ctrl + Shift + F1 and Ctrl + Shift + F7 quickly brings it back - better than having no touchpad scrolling.

pablo.t89 (pablo.t89) wrote :

I believe that so called "#18 fix" is not an actual solution. It disables multitouch features and makes your touchpad recognized as a normal mouse (and since touchpad doesn't come with separate physical scroll wheel, you won't get scrolling while using that option). You keep an ability to move your cursor and click, but that's not what I would call a "usable touchpad".

I wonder whether it's related specifically to the touchpad drivers, or is it just about the amount of cursor-related events which are sent to xorg? While it happens only with nvidia drivers, there migh be a possibility to fix it by pathing the touchpad-related protocols in psmouse kernel module or something in xorg (related to xrandr protocol, possibly?).

It was interesting thing when I tried to switch back to bumblebee from nvidia-prime. I have done these steps:
sudo apt-get purge nvidia-prime
sudo add-apt-repository ppa:bumblebee/stable
sudo apt-get update
sudo apt-get install nvidia-331 nvidia-settings
sudo apt-get install bumblebee bumblebee-nvidia primus primus-libs-ia32

But then I started World of Goo (from Steam) using optirun. And when in game startscreen I've pointed to profiles icon - there has been a freeze again!
I removed bumblebee, primus, nvidia-331.
After that I installed nvidia-319-updates, then bumblebee and primus.
And now i have no freeze at all.

So I think the bug is not in nvidia-prime but in nvidia-331driver, because with nvidia-319-updates there's no freeze.

A solution will be nice because this problem touch lot of users.

Having what closely looks like this bug with 14.04 LTS and Nvidia 610M+Inter HD4000 combo in a asus K55VD laptop. I can confirm switching VT as a working workaround. Also using an Elantech Touchpad.

@up: Definitely, following comment #18 makes the screen freezes stop. So does not touching the touchpad at all. Unluckily, neither of those two options lets you use the actual touchpad features like multitouch gestures (e.g. two-finger scrolling).

I have the same problem on ubuntu 14.04 with elan touchpad. I use a optimus laptop with nvidia 640m gpu and intel gpu. Using the touchpad causes ubuntu to freeze, and it is possible to unfreeze going to and from a virtual console. I am using nvidia 331 and prime.

I don't see any correlation with touchpad use.
In my case, window or application switching (alt-tab) is often very unresponsive (e.g. have to hold down alt-tab for 14 seconds before the switcher appears) (about 10 seconds in, a half-faded-in switcher appears).
Also, switching workspaces is often super unresponsive, freezing before jerking to the next workspace, or freezing halfway between workspaces.
In all cases, normal functioning resumes after 5-10 seconds frozen.

I am one of those who does not know how to apply a patch, so often have to get around this bug using Ctrl+Alt+F1 and Ctrl+Alt+F7, or external USB mouse. In general I am very pleased how much faster bugs get fixed in Ubuntu than in commercial operating systems. But this one has continued for over a year.

I have the same problem, or, at least, a similar one. My system is: HP Pavilion dm1 / Ubuntu 14.04.3 LTS / Radeon HD 6320 graphics / PS/2 Synaptics TouchPad.

My touchpad stops working periodically. A display swap (CTRL+ALT+f1 etc.) *sometimes* solves the problem, but I'm also finding that sometimes my keyboard stops working at the same time - which of course means that I can't swap displays using the keyboard. The problem does seem to be solved by connecting a USB mouse and a USB keyboard - but as it's a laptop I can't always do that.

I have tried the solution suggested at post #18. This worked very briefly, but before long the touchpad and (non-USB) keyboard stopped working again.

I have briefly looked at the solution suggested at post #251. Pardon my ignorance as a relative novice, but do I need to compile the package at https://launchpad.net/~snafu109/+archive/ubuntu/xorg-server ? I've added the PPA address as instructed, but I'm guessing that's not all I need to do?

If someone could help with this I'd be very grateful.

== Elantech Touchpad, the common hardware
After seeking on the net, I've find (here: https://devtalk.nvidia.com/default/topic/766166/elantech-touchpad-related-nvidia-driver-freeze/) that many people who experience the bug have an Elantech Touchpad and are using the synaptics drivers.

To check if you're in the same situation:
$ cat /sys/class/input/mouse0/device/name
->> ETPS/2 Elantech Touchpad

== Proposed workaround

It seems that the following workaround works, although I can't promise anything. We are however all expecting that NVidia developers fix their drivers properly.

    $ sudo apt-get remove xserver-xorg-input-synaptics-{your-flavour}
    $ sudo apt-get install xserver-xorg-input-mtrack-{your-flavour}

Hope you're doing better with that solution ;-)

I'm having this issue since the first boot of my new Dell Inspiron 5558 (with Nvidia GeForce 920M), and that's about 15 days already. Tried like millions of solutions including ones I found here, but nothing worked for me. Reinstalled Ubuntu for 20 times I think, from 14.04 to 15.10, tried UEFI and legacy boot (as someone somewhere suggested this as solution too), modified that one .conf file in modprobe.d as someone else suggested, added xorg-edgers repository and pulled the packages from it... I can't remember anymore what else I tried, but nothing helps.

Touchpad (pointer) freezes randomly without recognizable pattern. Sometimes right after the boot, sometimes 5 minutes after, sometimes one hour after, but eventually it will freeze, sonner or later. Sometimes it does not only freeze, it starts to act weird, opening right click menus while still frozen, like randomly generating all kinds of touchpad inputs. Sometimes it fixes itself after closing/opening laptop screen (going to suspend and waking), but this is not working every time also.

This is driving me insane. I love Ubuntu for years and I love my new DELL Inspiron, but having the laptop with defective touchpad defies its very purpose.

In my case, there is NO difference whether proprietary or nouveau drivers are in use, the freeze will happen regardless. I just had to add this clarification, as I see people reporting this issue is happenning only on proprietary drivers, which is not true in my case.

I'm testing the Win 10 Pro for the last two days, just to see if the same thing will happen, and yes, it does happen even on Win 10. Freezes occur less frequently, and are easily solvable by right then left button click on touchpad. It freezes whether Nvidia or integrated Intel graphics are in use.
It seems to me that this "elantech" touchpad is one @#&* of a touchpad, or the Nvidia card presence alone is making touchpad acts weird. Because, and I noticed that recently, even while in BIOS or live CD environment, touchpad freezes sometimes.
