Problems Encountered with Installation on an ASUS R501VM Laptop

[SteveRiley]

I'm guessing the lights still aren't working.

What's the output of these two:

ls -al /sys/class/leds

lsmod | grep wmi | grep -v rawmidi

[NoWorries]

Thanks for the clarification. I opened a second console after leaving the tail ... command running for over 1/2 hour. The output from the modprobe is now:

:~$ sudo modprobe -v asus-nb-wmi
[sudo] password: 
insmod /lib/modules/3.10.0-5-generic/kernel/drivers/platform/x86/asus-nb-wmi.ko 
:~$

The output from the tail .... that I left running now gives:

This should now make much more sense. In particular the hotkeys and backlight responses.

I am pleased to report that today is ideal ... blue sky - sunshine - 14C. A great place to live

What I found was that this command never returned to the prompt and I closed Konsole.

That's correct, it should just wait. Check the man page for tail (lol..."man tail") and you might see why I asked for this. It's because I want to see what's recorded to the system log when you run the next command.

The next modprobe command gives no output at all, probably because there is no asus-nd-wmi file.

modprobe only reports errors; successful module loads report nothing on the console. Thus, we have to look in the system log. tail -fing it helps us. (Er...something's in the water here in Virginia I think!)

So please try again, from another cold boot.

Thanks for your response to my problem. Hope the following helps.

Here is the output from the tail -f ...

You can't create /sys; it's automatically built by the kernel as it initializes devices. Read more about the sysfs virtual file system.

After a cold start of the machine, please open a console window and run

tail -f /var/log/syslog

Then open a second window and run

sudo modprobe -v asus-nb-wmi

Into a reply here, copy-pasta what you see in the first window, and any messages after the modprobe in the second.

After having great success with Saucy on a Compaq, I decided to test Kubuntu 13:10 on my ASUS R501VM Laptop. I did not want to alter the partitions on my SSD so I decided to install it on a USB memory stick. I initially tried a USB 2.0 stick and this gave unacceptably slow performance. Since my laptop supports USB 3.0 I ended up getting a USB 3.0 stick and this gave acceptable performance.

As I now have two systems to choose from, I used Grub Customizer to modify the boot menu and add graphics. With Saucy on a USB, I found that it was the dominant Operating System, so I had to to have Grub Customizer for Saucy. At this stage this is not available so I used the Muon Package Manager to add http://ppa.launchpad.net/danielricht...tomizer/ubuntu and defined the Distribution as raring. This worked so that I could make the first option Kubuntu 13.04 and the second Kubuntu 13.10. This lets my Wife use the laptop without too much change.

I soon found that the Australian mirrors still do not support Saucy so I had to change the source to Main to get updates. As of now, the main unsolved problems with my Laptop are:

(1) The keyboard backlights do not work. The way I got them to work on Raring was to edit the /etc/rc.local file and before the exit 0 add

echo 0x00050021 > /sys/kernel/debug/asus-nb-wmi/dev_id
echo 0x82 > /sys/kernel/debug/asus-nb-wmi/ctrl_param
cat /sys/kernel/debug/asus-nb-wmi/devs

On Saucy there is no folder /sys/kernel/debug/asus-nb-wmi. I found it impossible to create this folder. I did find that if I started Saucy in the recover mode and resumed normal boot, this file was created and the backlights came on! Unfortunately, this mode does not have the video drivers loaded. When I return to a normal reboot, the backlights do not come on and the asus-nd-wmi folder is not present.

(2) Network activity is not shown by either System Monitor, Network Monitor Widget or Network Management Widget. This only happens on my Laptop. There is certainly no problem with network activity except it is not shown.

All other aspects that I have tested work well and I am still very encouraged by the state of development. There are other problems which are less important. In this category is the system randomly not recognising the presence of my battery. To fix this, I have to unplug and replug the battery. The other problem is that reboot does not work.

I am wondering if others have had this sort of trouble, or alternately, am I the only one who has not been able to work out a solution?
