12.04 3rd party software graphs not working

[Terry Scott]

I have a 3rd party software which monitors and reports on some medical equipment which I use.
It's called Sleepyhead and is available to download from sourceforge.
I upload the latest data, on an SD card, twice a week.
As and when software update informs me, I install all updates.
Upto and including early Thursday 12th April GMT, it was working fine.
This morning, Sunday 15th April, I uploaded the latest info to a folder on my /home then launched SleepyHead as normal from terminal.
It crashed, if I remember correctly, with a segmentation error.
I re-installed it using software centre, still not working.
I de-installed it through synaptic then installed it through software centre.
Launched it ok but graphs all black screen.
Switched back to my 11.10 system, launched SleepyHead. Worked like it's supposed to, graphs and all and imported the latest data.
Switched back to 12.04, launched SleepyHead. Seems to be working without crashing but all graphs black.
Have not tried data import as already there from 11.10 test.
From the application wiki, it's written in c++

Terry Scott, thank you for taking your time to report this bug. With proper logs and terminal outputs it is not possible to investigate the segmentation fault error that you are experiencing. Please answer the following questions.

1. Are the version of SleepHead you tested on 11.10 and 12.04 the same? If now, it could be a bug in SleepyHead in which case you need to contact its developers.

2. Can you post the terminal outputs when you experience the segmentation faults. You could get this by trying to launch SleepyHead using the terminal, thereby all outputs are redirected to the terminal.

Please try to use apport to report bugs since it automatically gathers all the system information automatically and attaches it to your bug report which helps solve the problem easier. You can do this by typing "ubuntu-bug --unity" in the terminal or the dash without quotes. If you so wish you could also create a new bug report using this method.

Hi,

I can confirm that the version of SleepyHead is the same in 11.10, 12.04 and XP
The first time thesegmentation fault occured, a crash report was generated but, being a 3rd party software, that's as far as it got.
As I said before, it's only since that latest updates, those that were released since, and including, 12th April, that I started experiencing problems. I can take a screen shot of the what the application is doing under 12.04 and under 11.10 and I'll e-mail them to you

Hi Nekhelesh,

Have just updated the post, copied below:-

"I can confirm that the version of SleepyHead is the same in 11.10,

Attached are the screenshots from 12.04 and 11.10.
16.03.03.png is the incomplete 12.04
16.07.29.png is the 11.10
16.08.06.png is the terminal display from the working 11.10
16.17.19.png is the terminal display from 12.04

One note. I have not had any segmentation failures since removing the application with synaptic and re-installing through software centre.
Sorry to be so vague but it was working Thursday but isn't working now.
Something's changed but it's not Sleepyhead

Terry

I am reopening the bug. However, waiting for confirmation from any other user.

Begining to suspect this is a NVIDIA driver and / or hardware problem.
My motherboard is now getting on for six years old and am using the onboard graphics which, according to the NVIDIA site "should" cope with the onboard graphics..............
I've been trying 12.04 due to occasional system lockups in 11.10. These are usually shown by the screen remaining blank, if it's during boot, or by the screen going crazy. 12.04 is also doing it.

Have been trying a few options which have involved installing, re-installing, re-re-installing, installing older versions and upgrading in place, etc.
My "live" 11.10 system was built doing a roll forward.
Today I've cut a 11.10 CD, installed it, lowered the NVIDIA driver to level 173 and installed all updates.
I should now have two 11.10 partitions, one of which I will probably roll forward to 12.04 once I'm happy that both partitions are relativly stable and that I've got something to fall back on in case of problems.

[Terry Scott (terrykscott57)]

Sorry for the long time since last post. I've been having a few problems, both ubuntu and hardware.
I'll try and summarise:-
Installed my trusty 10.10 cd onto another partition. Tried to install SleepyHead but got version errors within Ubuntu.
Downloaded various .iso's
Created 11.04 and installed. Installed all updates and regularly used apps. SleepyHead installed and worked ok.
Created 11.10 and installed. Installed all updates and regularly used apps. SleepyHead installed and worked ok. Computer unstable with many shutdowns / system freezes. Tried various desktops, inluding K and Xubuntu's. Still shutting down but few system freezes.
Created and installed 12.04, non beta,. Installed all updates and regularly used apps. SleepyHead either crashed with "Segmentation fault (core dumped)" or failed to produce graphs. Computer unstable with many shutdowns / system freezes. Tried various desktops, inluding K and Xubuntu's. Still unstable. Finally resolved system shutdowns by loading ubuntu with ACPI=OFF and, when using Ubuntu, ensuring that I use 2D Unity.
As I understand it, the older NVIDIA drivers are not supported / compatible with 12.04?
I now have a 11.10 partition, a 12.04 partition and a 11.04 partition which has been rolled forward to 12.04.
At this time it looks like I can use 12.04 except when I need to use SleepyHead, when I shall have to revert to 11.10
Motherboard is Foxconn 6150K8MD-8EKRSH, last BIOS update 2007

Success!!!
I finaly got it working!

downloaded and installed the latest NVIDIA driver, NVIDIA-Linux-x86_64-295.53, from the NVIDIA website.
SleepyHead works on my 11.04, updated to 11.10, updated to 12.04LTS partition.
Will now work on my CD installed 12.04 partition to see if I get the same result.

[Terry Scott (terrykscott57)]

When is NVIDIA driver NVIDIA-Linux-x86_64-295.53 going to be added to the repositry?
The lastest repositry version 295.49 is unstable on my system

Please close this
My motherboard became part of the great computer in the sky............................................

[Terry Scott (terrykscott57)]

Now using Ubuntu 12.10, same version of SleepyHead, new motherboard GA-A55M-DS2 from Gigabyte
Using Unity or gnome-panel with effects I get the following:-

With gnome-panel with no effects, SleepyHead works
