[Touch-packages] [Bug 1801533] Re: lightdm does not start
This schouldn't happen. lightdm should only be started about 10 times, then disabled. BTW: no errors are readable on screen. Logs only show lightdm restarted by systemd after terminatating. Errors can be seen by disabling lightdm, then starting it from commandline. But this isn't helpful either: "Could not initialize screen.

[Touch-packages] [Bug 1801533] Re: lightdm does not start
Same problem: it does not matter if upgraded from 18.04 or installed new with 18.10. lightdm might not allways be capable initializing graphics leeding to some loop together with systemd turning on backlight, turning it off again, then restarting. Backlight is turned on, then off about twice a second. After some time backlight electronics break down, killing the monitor. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1801533 Title: lightdm does not start Status in lightdm package in Ubuntu: New Bug description: lightdm tries to initialize screen output, fails, tries again, fails until the backlight electronics break, killing the monitor. lightdm fails initializing screen.
