[CX700] Mouse, keyboard, and power button freeze

[captinkid]

Tested on 4 Cendyne cloudbooks, mouse, power button, and keyboard become non responsive while the computer continues running. It can occur at anytime after the background is displayed on boot.

The only work around is to plug in a USB keyboard and use the CRTL-ALT-F2 and use the terminal to reboot the computer.

No related errors listed in Dmesg or xorg.log after the freeze.

Please build/install the latest openchrome driver and enable debug mode.
The detail build instruction for Ubuntu/Debian is available at:
https://help.ubuntu.com/community/OpenChrome

Then attach your /var/log/Xorg.0.log file.

[Bartosz Kosiorek (gang65)]

When you switch to VESA, is everything is ok?

What happened when you run Ubuntu Jaunty?

[captinkid (captinkid)]

The mouse, keyboard and video card are currently frozen, I am
currently using an external USB keyboard to build the openchrome debug
driver.

I have saved the Xorg.0.log (current run with input freeze and
openchrome (non debug)) and Xorg.0.log.old.

Running with the command line interface is stable, however the input
freeze also affects the terminal and command line. External USB inputs
still function.

The inputs still froze while running X in vesa mode.

Jaunty would not install and boot reliably. It would freeze at random
points during the install process, and freeze seconds after X started.

Karmic installed properly, but it has the input freeze problem.

Is there any test I could run while it is frozen that would help
diagnose this issue?

What kind hardware do you have?
Add link to your hardware model.

I think if in Vesa this error still exist, then this is not in openchrome.

If you have FIC CE260 I found this article which should be helpful:

[Roberto Rosario (roberto-rosario-gonzalez)]

Also happens on the Sylvania G Netbook 13001
Same chipset: VIA CX700

[Bartosz Kosiorek (gang65)]

Please attach your xorg.conf file

[Bartosz Kosiorek (gang65)]

I found following an warning in your Xorg.log file:

(WW) AllowEmptyInput is on, devices using drivers 'kbd', 'mouse' or 'vmmouse' will be disabled.
(WW) Disabling Mouse0
(WW) Disabling Keyboard0

[Bartosz Kosiorek (gang65)]

I think you have enabled option:

    * Option "AllowEmptyInput" "false"

More information about this is available at:
http://fedoraproject.org/wiki/Input_device_configuration#Disabling_the_use_of_HAL

[captinkid (captinkid)]

I do not have:

Option "AllowEmptyInput" "false"

In my xorg.conf

Would that affect the fact that the inputs freeze after working
normally for several minutes? I would think that the setting would
stop it from working at all.

I switched my system over to "vesa" from "openchrome" and I am not
getting the regular input freezes. Also the system performance seems
to be just fine with the vesa driver.

It was crashing 100% of the time on the "openchrome" driver whenever I
tried to access gmail. It locks up the inputs as soon as you enter
your username and password and click to login.

[Roberto Rosario (roberto-rosario-gonzalez)]

I added the following to xorg:

Section "ServerLayout"
 Identifier "Configure Server"
 Option "AllowEmptyInput" "false"
EndSection

This resulted in duplicated keystrokes and the frozen keyboard/mouse problem still happened after a while.

In my case using an external mouse and the following grub command options almost eradicate the problem (is only triggered after several hours): "idle=halt io_delay=none pci=routeirq clocksource=hpet"

[Roberto Rosario (roberto-rosario-gonzalez)]

Changing the video driver to VESA didn't lowered the recurrence in a measurable manner for me.

[Bartosz Kosiorek (gang65)]

Try to remove this section in xorg.conf:

Section "Module"
 Load "dri2"
 Load "dbe"
 Load "record"
 Load "glx"
 Load "dri"
 Load "extmod"
EndSection

[captinkid (captinkid)]

I commented out that section, with the "openchrome" driver the inputs
still freeze on gmail login. With the "vesa" driver the inputs still
do not freeze on gmail login.

My /etc/X11/xorg.conf file is pretty basic

Section "Device"
 Identifier "Configured Video Device"
 Driver "openchrome"
# Driver "vesa"
 Option "DPMS"
# Option "SWcursor"
 Option "VBERestore" "true"
EndSection

Section "Monitor"
 Identifier "Configured Monitor"
EndSection

Section "Screen"
 Identifier "Default Screen"
 Monitor "Configured Monitor"
 Device "Configured Video Device"
EndSection

#Section "ServerLayout"
# Identifier "Configure Server"
# Option "AllowEmptyInput" "false"
#EndSection

Bug repeatable in final of Karmic 9.10 netbook remix

[Jack McSlay (jack-mcslay)]

same happens to me, but in my case it's not a notebook, but with the genius traveler 515 laser. It starts normally, but after some time it simply freezes. If I try to log off to reboot the X server, the whole system will freeze.

It seems totally random, sometimes I leave it doing nothing and when I return the mouse's frozen and the only I can do is plug another mouse or reboot the system. But it seems to happen more often when I'm using Blender or Wings3d

[GNET13001 (blondeendurance)]

I have been happily using the GNET13001 for about ten months. The freeze occurs when the cpu runs too slowly.

To make this thing work, you must first make sure that your kernel actually supports frequency scaling for the C7. In my case, I had to recompile the kernel. I do not know if more recent netbook remix kernels have this built in.

After that, make sure that you have the cpufrequtils package installed and run:

cpufreq-set --min 700Mhz

I know this is not a great solution. The cpu should be able to scale through all of its available range. OK. On the other hand, this transformed my GNET13001 from a paperweight into a useful netbook.

[captinkid (captinkid)]

As posted by GNET13001, the error seems to stem from the CPU min freq. A kernel patch or the following change used on the Acer Aspire one will get it running without the crashing.

> It means you have them. Now, my netbook is a VIA C7-M ULV (vs your Atom processor within that Aspire One), I have to raise cpu frequency scaling's minimum frequency value to stop those random freezing. You might want to take a look in your system's frequency settings:

Oh, almost forgot, don't remove cpufrequtils. These application are responsible to prolong your battery charge by downclocking (thus preserve electricity) within processor. Normally you have an "ondemand" setting which may throttle processing power up and down.

This bug was filed against a series that is no longer supported and so is being marked as Won't Fix. If this issue still exists in a supported series, please file a new bug.
