Dave, Is this reproductible on current F10 ? Could you post full dmesg and /var/log/Xorg.0.log as uncompressed text/plain attachments to this bug, please ? Thanks --- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers won't probably fix this at this stage, upstream code doesn't have this issue. |
