Description of problem: Without reason at a certain point my system logs out automatically. A black screen appear with strings (like the one you see starting up in older versions when there was no fedora logo), then the "choice user" screen appears, where i have to click on my user, digit my password and then it re-logs in. After some seconds it logs out again. It seems to be related to my Samsung Tablet connected as a MTP device at the login step, but i'm not sure at all Version-Release number of selected component: xorg-x11-server-Xorg-1.14.4-9.fc20 Additional info: reporter: libreport-2.2.2 backtrace_rating: 4 cmdline: /usr/bin/Xorg :0 -background none -verbose -auth /run/gdm/auth-for-gdm-mvVfXO/database -seat seat0 -nolisten tcp vt1 executable: /usr/bin/Xorg kernel: 3.14.7-200.fc20.x86_64 open_fds: runlevel: N 5 type: CCpp uid: 0 Truncated backtrace: Thread no. 1 (10 frames) #9 __memcpy_sse2_unaligned at ../sysdeps/x86_64/multiarch/memcpy-sse2-unaligned.S:171 #10 memcpy at /usr/include/bits/string3.h:51 #11 EVERGREENUploadToScreen at evergreen_exa.c:1726 #12 exaCopyDirty at exa_migration_classic.c:220 #13 exaDoMigration_mixed at exa_migration_mixed.c:118 #14 exaTryDriverComposite at exa_render.c:719 #15 exaComposite at exa_render.c:1006 #16 damageComposite at damage.c:563 #17 exaTrapezoids at exa_render.c:1149 #18 ProcRenderTrapezoids at render.c:759

Another user experienced a similar problem: Step 1: display locked up while I was away from it. Several hours after I was away. Step 2: I sshed into the machine from another, captured dmesg and /var/log/Xorg* Step 3: reboot (without power being off) Step 4: X never properly came up after the reboot. Step 5: shutdown, all the way to power off Step 6: reboot and run ABRT. Here we are. I'm not actually sure which step ABRT is reporting. The problem appears to be a nouveau bug. Certainly the dmesg output I've examined show problem with nouveau. Previously I've had nouveau lockups with ver pretty curdled screens.

Another user experienced a similar problem: System hangs randomly and display goes black. The frequency of this occurrance can be increased by watching flash videos or playing flash games. When this happens, the computer has to be reset manually. It doesn't reboot on its own. I'm hoping this stack trace isn't from that manual reset. The LCD monitor (model #W2242TQ) is connected via DVI. The graphics card is ATI HD5000 series. I think it's an HD5450, but I'd have to open the case to confirm.

Another user experienced a similar problem: I have an Acer Aspire X1200 (desktop), ever since I switch to Linux distros two years ago, I always have problems with my graphics. My computer uses Nvidia GeForce 8200, so the open source driver is nouveau. With others distros and Fedora 20, sometimes when I'm doing something, the screen freezes, the mouse moves but everything is stuck. Fedora 20 goes back to the login screen within several minutes but if not I have to restart my computer. This happens so often, I love Linux and Fedora, but this problem with my graphics or xorg server is extremely frustrating. Any possible fixes would be greatly appreciated.

More to offer, I was able to reporduce the problem by starting the same VM backup and running it again for a few minutes. I am running an Ubuntu 14.04 VM under Virtual Box. None of my other VM's cause this problem. I will post more ABART logs soon. Thanks, Devon

Good day, I have verified that I can easily recreate the issue in attachment 937286 [details] above by running the Ubuntu VM along or with other VMs. So it is only happening when the Ubuntu VM is running inside of Virtual Box. Let me know if you would like anything else specific from my system at all and I will provide it. Thanks, Devon
Hi all, I have narrowed down the condition on the Ubutu VM. When you disable 3D Acceleration the system does not crash. When you turn Enable 3D Acceleration it crashes again. Thanks, Devon
Another user experienced a similar problem: Every few days Fedora 20 becomes inoperable. The symptom is that both monitors go black and even though a mouse pointer is on screen, I cannot move it. I have a lot of programs idling in 6 workspaces, but no heavy load on the system. reporter: libreport-2.2.3 backtrace_rating: 4 cmdline: /usr/bin/Xorg :0 -background none -verbose -auth /run/gdm/auth-for-gdm-uWs8tP/database -seat seat0 -nolisten tcp vt1 executable: /usr/bin/Xorg kernel: 3.16.7-200.fc20.x86_64 open_fds: package: xorg-x11-server-Xorg-1.14.4-11.fc20 reason: Xorg killed by SIGABRT runlevel: N 5 type: CCpp uid: 0
This message is a reminder that Fedora 20 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 20. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '20'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 20 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
