stranger and stranger .. if you install kernel 5.0.0-8.9 at the first boot into any new install partition before changing any thing else .. it does not fix the issue .. once you return sda1 to being grub master .. neither sda7 nor sda6 will keep lightdm running ..both briefly flash lightdm login screen and then blank out screen , briefly showing a cursor .. a long hold down of power button does eventually powerdown machine .. note: can't even get to consoles .. not a nice fail.
note resetting grub back to the "new install version" works but there is a stutter in lightdm .. it shows briefly blanks for 2 seconds then shows again and and you can login.. only other way into partition is through recovery boot option, or via a chroot. this is now using xubuntu-am64-desktop.iso -beta version ( two installs sda6 and sda7 ) I'm beginning to think that using a chroot to reinstall/or update the kernel might be a "work around only" for the issue .. as a native update does not work .. I'm going to test this further .. replace sda6 and sda7 sequentially and see what happens using chroots for updates more later .. any ideas what else to look for or check? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1821609 Title: lightdm login screen briefly appears and then blanks out on Intel(R) Core(TM)2 Duo CPU T5870 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1821609/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
