RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

It's also reproducible on my colleague's computer, but only while disabling output.

Comment 15 Martin 2014-03-31 15:38:23 UTC

kde-workspace also crashes: https://bugzilla.redhat.com/show_bug.cgi?id=1082677

This is regression introduced in kscreen-1.0.1-8.el7.x86_64
kscreen-1.0.1-7.el7.x86_64 doesn't crash.

Downgrading kdelibs doesn't help. Regression is introduced in Kscreen.

Comment 19 Daniel Vrátil 2014-04-01 12:15:39 UTC

Please enable kscreen-console and KSRandR in kdebugdialog and run "kscreen-console monitor" in console, then reproduce the bug and provide full output from the tool.

There is only output after kscreen-console startup, nothing more on crash. kscreen-console is not in kdebugdialog.

$ kscreen-console monitor
START 
Config::current() took 149 milliseconds 
Remember to enable KSRandR or KSRandR11 in kdebugdialog
