Public bug reported: I had a few terminals and Chrome running. Started Eclipse from the GUI search, it started too load, the screen flicked to black for a moment then came back but was frozen. I have system monitor graphs going on the task bar and these were not updating. I could still move the mouse within the display it was in at the time of the crash but not on to the second display or over to my Windows box via Synergy.
After 30s or so the screen flicked to black and back again. Then I was returned to the login prompt. Once I logged back in the applications I had had open were closed. Inspected some logs to see what would come up. In kern.log I spotted: May 26 10:26:44 thorne-ul-dt kernel: [436212.122636] traps: unity-settings-[2567] trap int3 ip:7f84149d1c13 sp:7ffc1b310e70 error:0 May 26 10:26:50 thorne-ul-dt kernel: [436218.561645] compiz[2712]: segfault at 0 ip (null) sp 00007fff04c25ed8 error 14 in compiz[400000+3000] May 26 10:28:06 thorne-ul-dt kernel: [436294.229229] Qt bearer threa[10079]: segfault at 7fe2bc26ba50 ip 00007fe2eb821b84 sp 00007fe2715aa520 error 4 in libQt5Network.so.5.2.1[7fe2eb78d000+13c000] So to me this looks like a unity utility, compiz or a bit of Qt might have gone wonky. Is Eclipse written in Qt? I could imagine that being the case and that being a possible explanation for it being mentioned here. In syslog I spotted: May 26 10:26:31 thorne-ul-dt signond[1600]: ../../../../src/signond/signondaemon.cpp 388 init Failed to SUID root. Secure storage will not be available.

I did not disconnect and hardware so I guess the notes about monitors being disconnected will be part of the graphs system restarting. Also took a quick look to see if a some .crash report bits had been dropped: root@thorne-ul-dt:/var/log# ls -l /var/crash/ total 423588 -rw-r----- 1 thomasthorne whoopsie 79617614 May 26 10:28 _usr_bin_compiz.1000.crash -rw-r----- 1 thomasthorne whoopsie 2597271 May 18 14:55 _usr_bin_file-roller.1000.crash -rw-rw-r-- 1 thomasthorne whoopsie 0 May 18 15:54 _usr_bin_file-roller.1000.upload -rw------- 1 whoopsie whoopsie 0 May 18 15:55 _usr_bin_file-roller.1000.uploaded -rw-r----- 1 thomasthorne whoopsie 18737119 May 26 10:28 _usr_bin_signon-ui.1000.crash -rw-r----- 1 thomasthorne whoopsie 330529362 May 20 14:20 _usr_lib_jvm_java-7-openjdk-amd64_jre_bin_java.1000.crash -rw-rw-r-- 1 thomasthorne whoopsie 0 May 20 14:22 _usr_lib_jvm_java-7-openjdk-amd64_jre_bin_java.1000.upload -rw------- 1 whoopsie whoopsie 0 May 20 14:22 _usr_lib_jvm_java-7-openjdk-amd64_jre_bin_java.1000.uploaded -rw-r----- 1 thomasthorne whoopsie 2122088 May 26 10:26 _usr_lib_unity-settings-daemon_unity-settings-daemon.1000.crash -rw-r----- 1 thomasthorne whoopsie 133987 May 22 11:03 _usr_share_software-center_software-center.1000.crash -rw-rw-r-- 1 thomasthorne whoopsie 0 May 22 11:04 _usr_share_software-center_software-center.1000.upload -rw------- 1 whoopsie whoopsie 0 May 22 11:04 _usr_share_software-center_software-center.1000.uploade Looks like there are new ones in the form of _usr_bin_compiz.1000.crash, _usr_bin_signon-ui.1000.crash and _usr_lib_unity-settings-daemon_unity-settings-daemon.1000.crash but I did not see any automated prompt to send a report. That list of names might suggest that the automatic tool's inclusion of Xorg in the summary of this bug is unfair. Maybe it came from me choosing "Display Issue" in apport-bug. Shortly after I had an initial look through the logs I rebooted the machine. After that I used apport-bug to start reporting this problem. Let me know if there are any further steps I should take to try and diagnose this issue. I ran a memtest on my hardware about a week ago as I keep getting problems with this machine. It is new and we have two of them here at the office, both seem to get the odd problem. I think the guy using the other machine is using the latest stable release of Ubuntu but I do not know if he has reported any bugs yet. # lsb_release -rd Description: Ubuntu 14.04.2 LTS Release: 14.04 ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: xorg 1:7.7+1ubuntu8.1 ProcVersionSignature: Ubuntu 3.16.0-38.52~14.04.1-generic 3.16.7-ckt10 Uname: Linux 3.16.0-38-generic x86_64 .tmp.unity.support.test.0: ApportVersion: 2.14.1-0ubuntu3.11 Architecture: amd64 CompizPlugins: No value set for `/apps/compiz-1/general/screen0/options/active_plugins' CompositorRunning: compiz CompositorUnredirectDriverBlacklist: '(nouveau|Intel).*Mesa 8.0' CompositorUnredirectFSW: true CurrentDesktop: Unity Date: Tue May 26 10:57:33 2015 DistUpgraded: Fresh install DistroCodename: trusty DistroVariant: ubuntu ExtraDebuggingInterest: Yes GraphicsCard: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller [8086:0412] (rev 06) (prog-if 00 [VGA controller]) Subsystem: Gigabyte Technology Co., Ltd Device [1458:d000] InstallationDate: Installed on 2015-03-12 (74 days ago) InstallationMedia: Ubuntu 14.04.2 LTS "Trusty Tahr" - Release amd64 (20150218.1) MachineType: Gigabyte Technology Co., Ltd.
