Title: mysql doesn't start, but myth frontend & backend partially start, then fail when I manually start mysql Status in Mythbuntu, Ubuntu derivative focused upon MythTV: New Bug description: I upgraded to Mythbuntu 12.04 in late May (from 10.10, quickly through 11.04 & 11.10). I have been using MythTV for 4 years, but this is the longest period that problems have persisted. I use a combined Myth BE & FE PC, although last week I started exploring (successfully) using a slave BE, but that is not in operation. A few weeks after the upgrade, mysql no longer started during the boot up process. The Mythfrontend first menu does not appear. I am an end user, so it took a while to work out the problem & how to work around it. Now, after I boot the MythPC , I use Systems Monitor to confirm which apps are running ( mythtvbackend, mythtvfrontend, mythtvfrontend.real) & that mysql is not. In the meantime, the system tells me that Myth apps have crashed. I then open a terminal & start mysql (sudo start mysql). After a little while the first menu screen of Myth frontend appears, but the window is locked. After a little while a crash notice appears & the menu disappears. A little while later, the menu reappears & is functional. Another bug report message appears. Some of the time, I have tried to let the bug reporting system continue, but it usually fails. Mostly, I just disregard the crash notices, due to the frequency (multiple per boot), & the failure to continue to a report, but today I thought that I would persevere. If someone could tell me how to make sure that mysql would start during boot (I assume via upstart), it would eliminate a very frustrating sequence of events. I have seen comments on the internet about checking /etc/init.d/mysql, but I have no idea as to what the script does. Perhaps mysql does try to start, but fails, but I don't know how to confirm that. I have asked several people about upstart, but none of them have had any experience with it. If I am not home, my dear wife can't do any of the steps that I do. So, I do hope that one of you skilled people can make some sense of this. Regards, Garry.
