SELinux is preventing QSGRenderThread from execute access on the file 2F7661722F6C69622F7364646D2F23353236393538202864656C6574656429.
***** Plugin catchall (100. confidence) suggests **************************
If you believe that QSGRenderThread should be allowed execute access on the 2F7661722F6C69622F7364646D2F23353236393538202864656C6574656429 file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'QSGRenderThread' --raw | audit2allow -M my-QSGRenderThread
# semodule -X 300 -i my-QSGRenderThread.pp

I am running Fedora 25 with KDE Plasma Version 5.8.5. Kernel Version is 4.9.9-200.fc25.x86_64. Am using Nvidia proprietary drivers. Thanks, GregoryS This message is a reminder that Fedora 25 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 25. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '25'. 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 25 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 25 changed to end-of-life (EOL) status on 2017-12-12. Fedora 25 is no longer maintained, which means that it will not receive any further security or bug fix updates.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. |
Qt QSGRenderThread uses system resources to keep the lock transition files when desktop ( KDE PLasma ) is locked/non logged. Using proprietary nvidia/ati drivers, selinux is blocking the access of this resources making unable to unlock the desktop unless using terminal loginctl workaround. Confirmed that add access to the resources system returns to work.
