Hello, NX-ers!

We have successfuly installed navigatrix on our Acer laptop, everything works fine, but we dont have a pointer for the mouse. The touchpad clicks are working, and we are able to click on icons, but there is no pointer. If we connect an external mouse, the problem persists.
When I start up navigatrix from the stick, everything works fine.
Any ideas ?

Thanks Adrian and Ryan

As we say, "That's funny, not 'ha ha funny', but funny."

But just to clarify

It's just "invisible".

Since it worked in the LiveCD, and in the hard drive installation it 'works'...or not works as the case maybe, it is a case of loading up the wrong video modules (drivers).

This is going to be a lot of fun, so let's keep a lid on it.

Boot up the LiveCD and in a terminal, enter
sudo lsmod | grep video
Thsi lists all the modules (drivers). Output is piped (|) to grep to be searched for all occurrences of the word 'video'.

It looks like this.
[email protected]:~$ sudo lsmod | grep video
uvcvideo               73728  0
videobuf2_vmalloc      16384  1 uvcvideo
videobuf2_memops       16384  1 videobuf2_vmalloc
videobuf2_core         49152  1 uvcvideo
v4l2_common            16384  1 videobuf2_core
videodev              139264  3 uvcvideo,v4l2_common,videobuf2_core
media                  24576  2 uvcvideo,videodev
video                  20480  2 i915,acer_wmi
[email protected]:~$
In this broad sweep we are just looking for the line video 20480 2 i915,acer_wmi, (your's will be different) but cut and paste the entire output to a post.

But wait there's more....

Now boot to the hard drive installation and do the same thing. Because of the invisible cursor, if you want, modify the command sudo lsmod | grep video > ~/Desktop/lsmod_output.txt, or whatever you want to call it. This dumps the output into a text file on your Desktop.

Post, or attach that... and then we see about blacklisting the current module, and loading the one that works.

It's a little messy and fiddly, but it gets the job done. We'll make it pretty later.

Hello, Moe and others!

Thank you for your quick reply. We got out the laptop, and started it up again... This time we DO have a mouse pointer! I dont know what happened, maybe the one day sleep helped him get over this, but we dont have the problem anymore.
Thanks again, good nx-ing!

Adrian and Ryan
