Nothing to do with Qt but given our previous given out previous
conversation on how OpenSource bugs are left to rot then mass
exterminated, this one just showed up in my inbox this morning. It's
noteworthy because, yet again, to avoid working on something the
maintainer flagged the report "Incomplete." Given the amount of detail
in the report the "incomplete" status is laughable but an all too common
trick.

Title:
64-bit BOINC crashes with ever NVidia driver
Status in Linux Mint:
Expired
Status in boinc package in Ubuntu:
Expired
Bug description:
Linux Mint 17 'Qiana' KDE 64-bit
BOINC cannot identify CUDA with any of the NVidia drivers unless one
manually installs the backported nvidia-modprobe. 32-bit version does
not have this problem. In fact the 32-bit versions of things work
flawlessly. 64-bit appears to have never been tested.
Install BOINC.
Install Nvidia 331 driver
Reboot.
Launch BOINC manager select advanced view, Advanced->Event Log
Scroll back to the top and you will see a line stating something like "no
useable CUDA found.
Click on the little blue start button in the lower left corner.
In the little search bar at the top type "sour" and you should see an
option for "Software Sources" appear. Click it.
Click the "Additional repositories" button on left.
Click the "Add a new repository" button at bottom.
paste in the following:
deb http://archive.ubuntu.com/ubuntu trusty-backports main restricted
universe multiverse
Click "Ok"
Click the "update" or "refresh" button on upper right side of screen.
(This will be greyed out with "No action required" until you actually
add something and I don't remember what the text chagnes to.)
Exit out of all windows.
Click on the little blue start button in the lower left corner.
Applications->System->Synaptic Package Manager
Enter password when prompted.
After the index finishes updating type "modpro" in the "Quick filter"
field
Mark nvidia-modprobe for installation, then click "Apply changes"
Exit everything and reboot
Open your BOINC manager.
Click Advanced->Event Log
Scroll to top of log (it always shows last entry when it opens) You
should see something like:
Tue 10 Mar 2015 06:35:09 AM CDT | | CUDA: NVIDIA GPU 0: GeForce GT 630
(driver version unknown, CUDA version 6.0, compute capability 3.5,
2047MB, 1973MB available, 692 GFLOPS peak)
near the beginning.
Now, be sure to subscribe to Einstein@Home (other projects do use
CUDA, but I know this one uses it heavy and makes the problem happen.)
With the base 331 driver you can go for quite a few hours before
machine starts getting slow. If left with manager up over night most
mornings will display "NVidia Crash". This will be displayed by one
of two conditions.
1) Mouse will move on screen but nothing will respond. SSH in from
another machine and terminal applications seem to run.
2) You will wiggle the mouse and notice screens don't come out of
darked out mode. Looking down at the keyboard you will notice the 3
indicator lights turning on and off in sequence.
Installing 331-updates driver will let your computer operate less than
half a day.
Installing any of the 34x drivers out of edgers PPA will have you
crashing many times per day.
Note: with the 32-bit version you simply install BOINC, install 331 driver, reboot, and everything is flawless. This bug is 64-bit specific. If you visit this thread:
http://boinc.berkeley.edu/dev/forum_thread.php?id=10046&postid=61102#61102
you will see the desktop does not matter. Whether beautiful KDE or one of the
Gicky-Gnasty-Gnome desktops is used one achieves the same results.
