Shutdown problem as well as .dmrc Problem
 

Hello all,

I changed mice on my Ubuntu system, changed from PS/2 mouse to a USB mouse.

Prior to changing mice, this system was perfect.

Now the system does two strange things:

1) It will not power down by itself now, I have to hold the power button in for 5 secs.

2) When I log in, I receive a message about ignoring $home/.dmrc file because it does not have correct permissions.


I have chmodded the .dmrc file to all sorts of values such as 755, 777, 644 but no matter what I try this error will not go away.

Any thoughts would be much appreciated.

Greenie

First, do you have acpid running? It should read events like pressing power button and react on them. Also check presence of /proc/acpi/button , if there is no such dir, modprobe button . Your way does not let fs's to be cleanyly unmounted.

Proper permissions of .dmrc? I guess 600 .

Hi Raskin,

I checked if acpid is running by doing a 'ps x'

The following line would indicate that acpid is running, however not sure if correctly.

7509 ? Ss 0:00 /usr/sbin/acpid -c /etc/acpi/events -s /var/run/acpid.socket


I checked for the prescence of /proc/acpi/button/power

I have two directories in there "PWRB" and "PWRB" both of those directories have an "info" file in them.


I dont think there is a problem with the permissions of .dmrc as I have tried every chmod value that would make sense, and the error still appears. (It never was a problem until I added the USB mouse).

So I think the error is a side effect of something else.

Hmmmm,

Putting the 'user' into the 'user' group then . . .

chmod 700 /home/user
chmod 644 .dmrc
chown user .dmrc

Seems to fix the error at logon (not sure how any of this got changed)



I thought the shutdown problem was fixed by adding:

'acpi' to the /etc/modules file

but alas, its till has shutdown problem.

I have read comments about including acpi=on but no comments about how to do that. Does anybody know what this means? more info?

I had made an image of the Linux Partition prior to these problems, so I re-applied that image back to the Linux partition and rebooted this time with the PS/2 mouse connected.

I tested shut down a few times and had no problems.


I reconnected the USB mouse and the shutdown problems began again (the computer does not power off automatically). So I am 100% certain that using a USB mouse causes this type of shutdown/powerdown problem.

If I disconnect the USB mouse and revert back to the PS/2 mouse without reverting to my backed up image of the partition, the shutdown problem does not go away (ie: Connecting USB mouse causes indefinate power down problem).


The last message to appear on the screen during shutdown is as follows:

shutting down LVM volume Groups [OK]
[4294827.504000] Power Down

The system does not power down at this point.

Most Bizzarre,

Everytime I edit the /etc/modules file, the immediate following shutdown will work (power down works).

Then everytime after that, the power down fails at the end of shutdown.

I'll be buggered!

If I connect a PS/2 mouse in tandem with the USB mouse, the system powers down just fine, everytime.
