Thanks for the bug report. We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue. Please add drm.debug=0x04 to the kernel command line, restart computer, and attach * your X server config file (/etc/X11/xorg.conf, if available), * X server log file (/var/log/Xorg.*.log), not what you have attached above which is not a log file. * output of the dmesg command, and * system log (/var/log/messages) to the bug report as individual uncompressed file attachments using the bugzilla file attachment link above. We will review this issue again once you've had a chance to attach this information. Thanks in advance. -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
(In reply to comment #2) > * X server log file (/var/log/Xorg.*.log), not what you have attached above Sorry about that, the top of the file contained useless output and I didn't read it all the way down. It is a log, I'm sorry for my mistake. -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
Yeah, I'm not sure why that's showing up in the log -- a separate issue I assume. I'll reboot with the kernel debug option.
