Post subject: | Invisible mouse pointer on Acer E5-471 |
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 Attachment: Selection_012.png [ 41.45 KiB | Viewed 25592 times ] 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 Code: 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. Code: netty@netty:~$ sudo lsmod | grep video 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.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 netty@netty:~$ 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 |
