lcdproc for imon_lcd stopped working

[Bengt Nilsson]

The front panel display on my IMON-LCD served by the lcdproc daemon stopped working today 03-may-2013.

"dmesg | grep imon" shows

Most obvious symptom is that my /etc/LCDd.conf is set to turn off the backlight at boot, and as of from today it does not do that anymore.
The daemon i still running:

[Bengt Nilsson (bnilsson11)]

Could be related to unpredictable/changing /dev/lcd* device name between boots.
If the device name referred to in /etc/LCDd.conf does not match the real device name, nothing works.

[Brad Figg (brad-figg)]

This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 1176226

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

[Bengt Nilsson (bnilsson11)]

This is issue probably connected to Bug #1216366, which I reported later than this issue.
The device used by lcdproc, /dev/lcd0, if changing between /dv/lcd0 and /dev/lcd1 between boots, either toggling or random.
If /dev/lcd0 is set in LCDd.conf and the existing device is /dev/lcd1, of course nothing works.

Is this serious? Is some required info still missing?

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.13 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

[Bengt Nilsson (bnilsson11)]

I will try to test during the next following days.

Are the headers necessary?

[Bengt Nilsson (bnilsson11)]

Tested the kernel without headers briefly, did not seem to improve.
The device had stayed /dev/lcd1 for a while with the old kernel, and I would have expected it would change to /dev/lcd0 stable with the new kernel but it did not. It remained as /dev/lcd1 after the first boot. Not conclusive, but I had no possibility to spend long time with the new kernel since it did not seem completely compatible with my system, I am using the lowlatency kernel in ubuntu-studio.

[Bengt Nilsson (bnilsson11)]

I will give it a try once more over the weekend.

[Bengt Nilsson (bnilsson11)]

Now testing the 3.13 kernel.
Now (12-jan 11:30) I have rebooted about 10-15 times, and the first two times it flipped, but now it seems to be stable at /dev/lcd1.
I will keep the kernel and keep rebooting during the week.
However, I still think it is strange that it is /dev/lcd1 and not /dev/lcd0.

[Bengt Nilsson (bnilsson11)]

Seems to be fixed.

I added the tag "kernel-fixed-upstream"
