[Ubuntu-x-swat] [Bug 1290342] [NEW] Frequent System Hangs

I get frequent system hangs...
...sometime xorg restarts itself, many times it does not.

Usually I have no keyboard or mouse clicks when it hangs.  Sometimes I
can move the cursor around the screen, but am unable to click on
anything.

If I have an active (95 chars by 45 lines) terminal, then it will
usually resize the terminal to the default size (80 chars by 24 lines).

It does not seem to matter what application software is running.  I have
seen the problem occur with firefox, system monitor, terminal sessions
running REXX scripts, gedit, and th file manager.

It does not seem to have  an real pattern that I have been able to
discover other than SIGABRT eventually showing up in various other
routines such as  GNOME.

My display card is a dual display 8600GTS with 512M onboard. I have been
using that card since I first started with Ubuntu 8-04 and 10-04 and it
worked exceeding well until I upgraded to 12-04 (12-04, 12-10, 13-04,
14-10)

When I first instralled the card I was able to support 4 monitors. One monitor 
on one port and the other three on the second port connected thru a 
Tripple-togo external adapter from Matrix.  the two seperate sets of monitors 
were run as separate x-windows
and I was very, very happy with that setup.

under 12-04 and all successor versions, the seprate x-server mechanism
has NOT functioned - resulting in my removal of the tripple-to-go
adapter and its three monitors from this system.

I now only run a single monitor, and am so severly plaged with XORG
failures, that I can no longer use this system as part of my Ham Radio
setup, as the system is too unstable to use in digital communications.

Please note, ALL system failures have been transmitted to UBUNTU for the
past four years.

[Ubuntu-x-swat] [Bug 1184451] Re: Ubuntu 13.10 random screen freeze while Normal OS activites

[Bill Turner, wb4alm]

Like many others, I have been getting random screen freezes since July
2013.

They are more frequent under 13.10, but I was also getting them under
13.04

I have a quad processor, and it seems that if one cpu approaches 100%, I am 
much more likely to see a screen freeze.  Some of the freezes clear themselves 
in a time fram of 15 seconds to a couple of minutes. If more than two of the 
copu's go to 100% it is highly probably that a Hard reboot (with the power 
switch) will be required.
(Could there be a kernal logic problem in signalling between the cpu's?)

When the unfreeze occurs, I will see a screen flash and then the
screen is rewritten and everything is fine for a while.

If the unfreeze does not occur within a few minutes, I have found that a
hard reboot with the power switch is necessary.  Sometimes when the
screen freezes, the cursor can be moved, but button clicks will no
longer work, nor will the keyboard.

My keyboard and trackball are both USB if that makes a difference, and
my VIDEO card is a NVIDIA GeForce 8600 GTS using NVIDIA's 304.88 driver.

I have had multiple monitors attached to my system in the past using my
dual port card, but in the last 6 months have only had a ViewSonic
VA1930wm at 1440x900 pixels. (In fact, prior to ubuntu 10.04, I was able
to run them as separate x-screens, but that went away with Ubuntu 10.04)

As a radio Amateur, I frequently run a program called FLDIGI to control one of 
my Radio Transmitters. When I had FLDIGI configured to use portaudio, 
everything was fine from Ubuntu 8.04 all the way to Ubuntu 10.04. 
With Ubuntu 10.04 I started to get some freezes using Portaudio and under 
Ubuntu 12.10 it was totally unusable - so I switched to PulseAudio (as 
recommended by the FLDIGI author), and as a result the freezes were less 
frequent until Ubuntu 13.10, when the freezes became quite frequent.  

I have no way to tell if the problen is X-server related, or if it is
pulseAudio related, or if it has to do with signaling within the kernal.

Sometimes when the system fixes itself, a problem analysis is created
and I assume is transmitted to Ubuntu support.  I know for a fact that
NO report is generated when I have to hard boot the system.

If the screen freezes and can not be fixed, then I will have to abandon
Ubuntu and go to mint 13 or mint 14 like a lot of other Radio Amateurs
have already done.

It is just not acceptable when I am in the middle of a radio
conversation with other Radio Hams to have the Ubuntu system freeze and
cause my radio transmitter to suddenly stop sending data, but continue
to transmit a signal, and then go suddenly off the air when the system
is rebooted.   Not only is it not polite to just disappear, it is a
violation of the FCC's rules and regulations to not end the transmission
with my call sign.
