Red Hat Bugzilla 501125 0 low CLOSED Xorg uses 100% of the cpu and locks up 2021-02-22 00:41:40 UTC

Description Tim Lloyd 2016-08-24 07:36:56 UTC
Hi,

This morning I lazily clicked on a document in LibreOffice and my screen locked up (F24, Gnome classic). I could ssh in from another PC and I saw that xorg was chewing up 100% of CPU time - I ended up rebooting. No problems after that.

I found an old, slightly similar, bug ID 501125. The maintainers requested on that bug, xorg log and conf however the log file has moved since 2010. I have copies in /home/tim/.local/share/xorg if you would like me to post this.

I booted into the latest kernel this morning 4.6.7-300.fc24.x86_64, about 2 hours before this problem occurred.

Sorry for the minimal information/ Let me know what else could help to zero in on this problem. FYI, here is my lspci output

Comment 1 Fedora End Of Life 2017-07-25 22:37:02 UTC
This message is a reminder that Fedora 24 is nearing its end of life.
Approximately 2 (two) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 24. 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bug reports from releases that are no longer maintained.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 '24'.

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 24 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.

Comment 2 Fedora End Of Life 2017-08-08 16:45:47 UTC
Fedora 24 changed to end-of-life (EOL) status on 2017-08-08. Fedora 24 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no longer maintained, which means that it will not receive any further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.
