This also effects Mint 17 KDE 64-bit. I have a 6 core AMD which currently has only 4Gig of RAM. It took me a while to figure this one out. During the evening the machine is running BOINC. The parameters I have set on BOINC tell it to upload between 3-6am. When I quit for the evening several of the tasks had multiple hours left to go. In the morning with screen locker set to random I was hardlocked. When I rebooted I checked BOINC. those tasks had finished but not uploaded.

At first I thought it might have been a problem with the many buttoned Logitech keyboard I had connected because it had some sleep/wake controls. Swapped it out for a basic K120. Next morning same problem.

Changed screen locker to simple locker. This morning I wiggled the mouse and the screen came back. I thought there was joy. Hard drive light was still flashing intermittently so BOINC was still running. Mouse could move, but clicking various desktop icons, even the KDE button and Dolphin. Nothing worked. After rebooting I checked BOINC and it appears to have run all night.

I have no disabled screen locker. Will report back in a day or so.

It appears to have locked up even faster. I booted Mint 17 so it could run BOINC. The automatic checkbox was not checked, but the require password was. Radio button for simple locker was checked. Judging from the current task state in BOINC (after rebooting via reset button) it didn't make it half an hour.

I have now changed it to Automatic, 27 minutes, no password, Blank screen.

I have to find _some_ form of these settings which will let the machine run more than a couple of hours unattended.

I was locked up again this morning. Now trying one final combination. Neither start automatically nor require password checked. Selecting "Blank Screen" from the list of possibilities. Simple locker definitely locked me up and it seems to have done it inside of 3 hours justing from where the BOINC tasks quit.

Finally identified the problem. I had an ASUS video card with an Nvidia chipset. The default driver xserver-xorg-video-nauveau (sp?) is bad. On a whim I installed the proprietary nvidia-331 driver. All is well. I have since swapped out that video card for one with 300+ cuda in order to participate with some additional BOINC projects. If the support/developer for that driver is in America I can ship the card to them.
