[Bug 189814] Re: [hardy]computer and touchpad is buggy when running on battery

2008-06-30 Thread Saïvann Carignan
I can confirm that this bug can only be reproduced when the laptop have
a BIOS password set! Thanks for finding this!

** Summary changed:

- [hardy]computer and touchpad is buggy when running on battery
+ [hardy]computer and touchpad is buggy with BIOS password set

** Description changed:

  This bug happens with a freshly installed hardy beta 1 when the computer
  is running on battery or at the moment I plug/unplug the electric cable
  into my computer.
  
  If I let the computer unused for some minutes (2-5 minutes), when I come
  back and try to use the mouse, the mouse move of some centimeters,
  suddenly freeze for almost 5 seconds, and then come back to life. It can
  be reproduced since it continually happens each time I use my computer
  after reading a short text or spooke to somebody. If I plug or unplug
  the electric cable, the mouse freeze again for a 7 seconds. If any
  sounds are playing during the time that the mouse freeze, the sound is
  also corrupted and freeze.
  
  This bug does not happen when the electric cable is plugged, and it
  happens with metacity as much as compiz.
  
  Each time that the mouse suddenly freeze, I get this in dmesg :
  [  804.829840] psmouse.c: GlidePoint at isa0060/serio1/input0 lost 
synchronization, throwing 4 bytes away.
  [  807.405427] psmouse.c: resync failed, issuing reconnect request
  [  810.926845] input: PS/2 Mouse as /devices/virtual/input/input9
  [  810.973805] input: AlpsPS/2 ALPS GlidePoint as 
/devices/platform/i8042/serio1/input/input10
  
- This might maybe be linked with bug 190414, tsc clocksource does not
- work on my laptop with Hardy kernel so linux switch to hpet instead
- after ~35 seconds waiting at boot.
- 
  This bug is not a hardware failure because it is not reproducible under
  Linux Ubuntu Gutsy and Windows XP.
  
  Dell Inspiron 9300, i386
+ 
+ Update : It has been found that this bug only appears when there is a
+ BIOS password set on laptop computers.

Hi... I can confirm that the problem disappears with no BIOS password.
Keep in mind that this didn't happen to me with kernel 2.6.22 and
started since 2.6.23 or .24... so might be somehow related?

I really took interest in fixing this and it seems I finally hit the
root of the problem. Thanks to you all for your comments and trials, as
without the hint on gnome-power-manager I would never have though of
such a thing. The community is always great!

If others having this problem confirm that it disappears with no BIOS password, 
probably the best thing is to open a new bug against HAL with concise infos. 
I'll be glad to do it myself tomorrow if nothing new shows up here.
It's nice to have stability again.

I've been trying dellLcdBrightness for a while. It doesn't matter if I
enter the correct BIOS password or not ("dellLcdBrightness -a -v 1"  or
"dellLcdBrightness -a -v 1 -p "). My D420 still acts as if it
was locked.

Removing BIOS password works perfectly for me.

[Bug 189814] Re: [hardy]computer and touchpad is buggy when running on battery

2008-06-30 Thread Andrea Ratto
This is my idea:
gnome-power-manager tries to dim the brightness of the screen after some 
inactivity and then reset it upon input.
gnome-power-manager calls HAL to do the job. HAL has multiple methods of 
handling brightness of LCD panels. On dell machines, since hardy it uses a 
libsmbios.
Libsmbios has only rudimentary support for setting the brightness thought. For 
example it does not work if a BIOS password it set and apparently on some dell 
models.
However, instead of just printing an error when it fails, it makes the computer 
lock for a few seconds, due to the direct interaction with the bios on a very 
low level.

There is a very easy way to try if it work on your computer using the command 
/usr/sbin/dellLcdBrightness from libsmbios-bin package.
Here's a command that rapidly switch brightness 10 times:
for x in `seq 1 10`; do sudo dellLcdBrightness -a -v 1;sleep 0.1;  sudo 
dellLcdBrightness -a -v 5; done 
#Warning it may hang your machine

Without a BIOS password it works fine on my laptop (D630)

Another way could be with the brightness applet of the gnome-panel.

A possible elegant solution:
Correct HAL's detection of this capability, so that it only reports it when 
brightness can be set with no errors. Maybe also add some way for HAL to read 
the bios password from config files if the user wishes so. Oh and fix libsmbios 
to avoid stalling on error, that is ugly.
Less elegant:
turn off HAL's usage of libsmbios in some config file and have users who want 
it to manually set it.

possible temporary workaround:
blacklist the dcdbas kernel module
disable dimming in gnome-power
I don't know how to disable it from HAL, but that would be the best workaround.

NOTE: if HAL is allowed to use libsmbios a local user could exploit it
to induce a denial of service or crash.

I hope this info proves useful.

2008-06-30 Thread Aitor Pazos
With last kernel and modules update (2.6.24.29-generic) I don't get the 
following messages anymore:
[ 266.266778] psmouse.c: GlidePoint at isa0060/serio1/input0 lost

[ 269.718340] psmouse.c: resync failed, issuing reconnect request

No more kernel panics either.

But after being a while ( 10-20 seconds) without using it and with no
cord plugged there is a strange high CPU usage for about 3 seconds and
the pc seems to be hanged. Even playing music starts making noise. This
behavior isn't new but is the only symptom that still occur on my
laptop.

I think I now where the problem lies ultimately. Can you just do a small
test for me? Add a brighness applet to the gnome panel and try to see if
that works smoothly. 

On my d630 it does not work with a bios password set, but does without.

In a duplicate (#243595) of this bug there is this comment:

"I disabled "Dim display when idle" in both AC and BAT on Gnome Power
Managment and it works OK. No need for kernel paramaters though. I'll
keep testing."

I did this on Intrepid Alpha 1 and to my surprise i can't reproduce the
bug anymore by unplugging my powercord or leaving my laptop for a few
minutes untouched. When I enable "Reduce backlight brightness when
inactive" again, the bug is back.

2008-06-29 Thread Andrea Ratto
With the heat of these last days it seems to happen even more. Kernel 
parameters did not solve the issue.
Yesterday I also uncovered something. I was watching a video on youtybe and had 
the screensaver coming in every minute, so I touched the touchpad everytime the 
screen started to go black. This mostly resulted in a few second of audio 
looping and gui freeze. Interesting is that it happened with the touchpad, the 
"touchpoint" and the keyboard itself.  So it is not specific to touchpads or 
the tiny blue "touch point", but also can be triggered by the keyboard. 

Can also someone CC dell on this bug? 
PS happened a total of three times during writing of this and crashed my laptop 
around 3 times a week since hardy installation, so how about setting priority 
to high? If it does not get solved I will have to switch distro...

I can confirm Andrea's findings 100% it sums it up for me completely.
Especially that there is no relation between inplugging / outplugging of the
battery.
On the side, my now 80% complete switch to mandriva to avoid this bug
learned me that (k)ubuntu should drastically improve its kde integration...

I any testing on a dell needs done I'm available with a D830.

still present with 2.6.24-19-generic. Here are my findings:
1 battery or not battery it happens
2 it starts when using again the touchpad after a period of inactivity. (Maybe 
on battery this period can be shorter)
when it starts it freezes everything for some seconds, CPU usage get to 100% on 
all cores. At this point if you keep insisting on the touchpad you can really 
crash the machine. If you let go it usually just pass but you have to notice 
quickly.
3 sometimes the touchpad looses touchpad functionalities (eg scrolling on the

4 dmesg entry "psmouse.c: GlidePoint at isa0060/serio1/input0 lost

5 many people are having this problem, someone also on fedora, someone since

2008-06-03 Thread Andrea Ratto
I have this very same problem with 2.6.24-17 generic on a dell latitude
d630. And it really bothers me.

My latitude has a "touch point", a sort of secondary mouse in the middle
of the keyboard. I was wondering if this bug is somewhat related only to
similar hardware configurations. Is there someone that does NOT have
another mouse/touch point and experience this problem?

Ironically I was trying fedora 9 because of this problem with the thouchpad and 
related instability and got it there too. So it is 99% sure not Ubuntu specific 
and it is not being fixed in 2.5.25! That's one sneaky and evil bug.

[Bug 189814] Re: [hardy]computer and touchpad is buggy when running on battery

2008-05-12 Thread Saïvann Carignan
I got to reproduce the bug again today. The bug does not happen
immediately when unplugging electric cable like it did in the past, but
if I let the laptop without any activity for ~10 minutes, the mouse
freeze.

No problem. 
Sorry for dmesg because I've suspended my laptop and interesting messages may 
be lost in me middle of a bunch rubbish

Aitor Pazos : Thanks for your fast confirmation. Can you attach the 4
files created by these commands in a terminal?

uname -a > uname-a.log
cat /proc/version_signature > version.log
dmesg > dmesg.log
sudo lspci -vvnn > lspci-vvnn.log

I get the same output and it behaves as described. Sound also stalls for
1 or 2 seconds when computer is idle for a while without touching
anything.

dmesg output:

synchronization, throwing 2 bytes away.
