Please add emerge --info lightdm mesa. Additionally, please take the time to read https://wiki.gentoo.org/wiki/Bugzilla/Bug_report_guide. I know you are a frequent bug reporter. emerge --info and bug summary really shouldn't be things you are missing in your reports at this point...

Sorry that I did not provide more detailed information. Some 'emerge --sync; emerge -uvDN world' and reboots later everything is again fine. I can start lightdm without any issues. Regards, Juergen
