usb mouse and keyboard temporary freeze of laptop

[francois]

Since edition 3.0 of porteus, I have had some temporary freeze with the mouse and the keyboard attached to my toshiba satelite z930, but not to the keypad and keyboard of the laptop.

First, I thought this could be due to the batteries and then to my usb logitech mouse and keyboard. I changed the batteries, with no improvement. Then I changed the mouse and keyboard and the problem was still there. Looking on internet with keywords temporaty mouse freeze linux, I got this frustration saving thread:
http://askubuntu.com/questions/161657/w ... tery-power

The solution was to modify some parameters in /etc/laptop-mode/conf.d/usb-autosuspend.conf. It should have been evident, this is my reasoning, that laptop tend to try to save energy. I imagine that suspending usb devices is one way to acheive that.

Checking into the /etc/laptop-mode/conf.d/usb-autosuspend.conf to modify some parameters, with the help of the lsusb output I have blacklisted my logitech usb mouse and keyboard according to the instructions so that they do not get into autosuspend mode automatically.

For now, everything seems to be functioning well.

This is a report for the record, in case someone else run in some similar type of problem.

vary useful - thanks for posting.

In fact, I noticed a difference with porteus arch version of stifiling for which there was no such behavior and porteus stock which would have these freeze of the mouse and keyboard. This leaded me on the right path.

1) Another option is changing the autosuspend time from two seconds to a greater amount of time for all the usb devices:

Code: Select all

# USB Auto-Suspend timeout in seconds ***SUSPENDING FOR 20 minutes***
# Number of seconds after which the USB devices should suspend
AUTOSUSPEND_TIMEOUT=1200

2) But better than that is to blacklist usbhid auto-suspend, usbhid means mouse, keyboard and joystick:

Code: Select all

# The list of USB driver types that should not use autosuspend.  The driver
# type is given by "DRIVER=..." in a USB device's uevent file.
# Example: AUTOSUSPEND_USBID_BLACKLIST="usbhid usb-storage"
AUTOSUSPEND_USBTYPE_BLACKLIST="usbhid"

I propose that porteus be set to AUTOSUSPEND_USBTYPE_BLACKLIST="usbhid"[/code]

And to set the default action for Lid Closed to be Sleep. And the default action for Low Battery to be Shutdown after 5 mins. That way if the lid is closed for an extended period and the battery gets low a user's changes don't get lost unexpectedly. Obviously a user can change these values and actions if they choose to but the defaults will be safer than the current ones.

thanks - will consider those.

@fanthom:
Thanks for your wide and wise mind. With porteus we are really into produsage. Citing: Axel Bruns on GPL communities:
http://old.slax.org/forum.php?action=vi ... =produsage

The concept of produsage highlights that within the communities which engage in the collaborative creation and extension of information and knowledge that we examine on this site, the role of consumer and even that of end user have long disappeared, and the distinctions between producers and users of content have faded into comparative insignificance. In many of the spaces we encounter here, users are always already necessarily also producers of the shared knowledge base, regardless of whether they are aware of this role - they have become a new, hybrid, produser."(http://snurb.info/produsage)

Already a long road has been done since these days on the slax forum. In addition to their great presence, here the leaders and the maintainers give a lot of place to the will of the forum members.

set the default action for Lid Closed to be Sleep.

was thinking about this and decided to not do it as user may download something in the background (torrent) or stream video on a TV (i do it often myself).

default action for Low Battery to be Shutdown after 5 mins. That way if the lid is closed for an extended period and the battery gets low a user's changes don't get lost unexpectedly.

will do for KDE4 and LxQT (if possible). brokenman decides about MATE and XFCE.

thanks

But for people doing these things, with their lid closed, they could simply change the default to fit their needs.

Nice to see you're still thinking about these suggestions.

well - you could do the same

Nice to see you're still thinking about these suggestions.

started working on rc1 for next Desktop release and these were on my TODO list among others.

off topic: wish uClibc could release something after 2 years as i cant upgrade e2fsprogs in the initrd (needed for fsck):
http://lists.uclibc.org/pipermail/uclib ... 48561.html
of topic2: 'vga_detect' cheatcode is on the way out if i wont find reliable way of extracting PCIIDS for latest generation of AMD GPUs (R 9xx)
in short - usual Desktop edition headaches has started
(not saying that Kiosk delivers less ... cause it's contrary)

True enough, if I knew I needed to, but do you want the safe default to be for newbies, both to Linux and to Porteus, or for experienced users?

I don't envy you but am reasonably confident you will find a way.

I know this not on topic but as we are there with these different changes. What about setting out of the box the screen brightness a little lower.

[fanthom]

@francois
hmmm... this depends on preferences/hardware specs so i would leave it up to the users.
if you screen is too bright then you can change it in the laptop-mode-tools config or DE power settings.

@Ed_P
same thing - it's impossible to find preference which makes everybody happy. i would leave it up to the particular desktop maintainer. for DEs i maintain the lid behavior wont change.

[Ed_P]

@fanthom, where is the Lid Close option saved? I want to make a module of it and use it with Always Fresh mode. I looked in /home/guest/.qt but didn't find it. And there is no /home/guest/.razor folder.
