okay I have another solution to the timing issue .. add two partition mounts to fstab .. my existing sda1 disco install has /home (sda2) and /home/store1 (sda5) mounted via fstab .. this was the original install configuration .. thus always a mount delay .. to test .. added the same partions to mount on /home/oldhome and /home/store1 respectively on newly installed sda9 - disco xubuntu final and no crashes .. ..plymouth shows up .. xorg/lightdm start normally ..just enough delay to let everything else happen .. all using the "foreign sda1 installed grub" .. so all the errors are due to "faster than expected storage media response time" .. some slumbering boot timing issues waiting to cause trouble .. -- 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/lightdm/+bug/1821609/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

of course the sda1 partition (on the SSD) has never failed to work properly no matter which grub source (installs on sda1,sda6,sda7,sda8,sda9) is used plymouth always appears when sda1 boots.. this disco version was installed jan 10 with a bootstrap log date of oct 13, 2018 .. it has been updated regularly ever since .. daily from proposed .. without issues .. other partition installs through most of febuary tested about once per week not always reported .. appeared to have no issues .. so the question to be answered is what change in late february /early march could have influenced the timing of the boot sequence and the start of plymouth ? any ideas? -- 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/lightdm/+bug/1821609/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

okay turned back the clock .. to a spinning metal disk previously installed in this hardware .. ran a number of test installs all work fine .. cosmic/bionic/disco early version disco final all work boot normally .. always .. thus conclusion is a SSD is very fast and can respond to requests sooner than a spinning metal disk this throws off the timing of a number of boot processes .. which become out of sync.. due to the " slower processor " now the first boot into a fresh install is not effected as a very extended plymouth start occurs .. due to " automatic-updates?? or disk checks or something ?" the rest of the boots are too fast for even plymouth to load properly due to a not yet loaded kernel video module .. thus it only flashes the screen red briefly .. then xorg/lightdm crashes for the same reason(?).. delayed kernel module load .. then a second successful try if still booting from "native" grub ..else no retry and lock-up -- 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/lightdm/+bug/1821609/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I will try to do videos for you tomorrow it is getting late in the day here .. a brief synopsis for now .. history: this is standard grub arrangement as "installed by default" used to work flawlessly with multiple partitions of various linux OS's .. It is only since early march that I noticed an issue with newer install disco boots failing .. I have an older disco install on sda1 which has been working all this time through without issues .. upgraded daily .. no alteration of netplan config or i915 module forcing.. I can prevent failures in two different ways .. add the module to /etc/modules or change netplan config to not use NetworkManager as the default.. attached my suspicion is that NetworkManager is crashing the system by running too early as on part of the failure.. the second part is slow loading of the necessary kernal module i915 this may be also the reason the plymouth (busy screen) does not show in the boot phase of the effected partitions which are all recent disco xubuntu spins.. an ubuntu install showed no issues .. wayland only works! When using the freshly installed grub with the partition it belongs to we get the first boot normal every thing works .. but on restarting again (2nd boot) xorg/lightdm initially crash then in about 6 seconds xorg/lightdm restarts ..and works on any other disco-xubuntu partition (except sda1) booting from this fresh grub .. we get the initial crash of xorg/lightdm and a locked system .. no restart of xorg/lightdm at all .. no console either .. only the power switch/ power removal works to reset .. and thus " a very perturbed and frustrated tester " ** Attachment added: "01-netcfg.yaml (password obscured)" https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1821609/+attachment/5256176/+files/01-netcfg.yaml -- 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/lightdm/+bug/1821609/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1821609] Re: lightdm login screen briefly appears and then blanks out on Intel(R) Core(TM)2 Duo CPU T5870 (crash in xorg before using "foreign grub") netplan mis-configuration maybe underlying ca
Okay, this bug has absolutely nothing to do with grub or netplan. Changing the renderer couldn't possibly affect the behavior of X, and the grub configuration looks, at a glace, to be run-of-the mill; pretty much default if you disregard that there is any number of different installs on the system. For instance the kernel command-line: BOOT_IMAGE=/boot/vmlinuz-5.0.0-7-generic root=UUID=1d61086d- 275b-4537-bed5-f2d3080670eb ro quiet splash (from various attached output of dmesg) This command-line is pretty much default. The use of kernels 5.0.0-7 or 5.0.0-8 are what I'd expect on disco images; and there are no special kernel parameters being passed. I don't know what partition root= points to; but this is the only possible thing I could see. Grub really doesn't care what you want to start, it will just run the kernel and initrd you tell it to. Unless this is a quite unforeseen and unlikely bad interaction between kernel drivers and the limited gfxmode changes we do in grub... but we'd see this on more than just this system. Could you please attach a video or pictures of what you're seeing on the screen, along with clear details of *any* modifications you do to boot something, how you set up your tests, so that we could potentially reproduce this or see what is happening? I'm cleaning up the title here for clarity; but this seems like either a kernel bug, some missing modules for your particular setup, or bad interactions because of the very complicated multi-boot scenario you're presenting. ** Summary changed: - lightdm login screen briefly appears and then blanks out on Intel(R) Core(TM)2 Duo CPU T5870 (crash in xorg before using "foreign grub") netplan mis-configuration maybe underlying cause. + lightdm login screen briefly appears and then blanks out on Intel(R) Core(TM)2 Duo CPU T5870 ** Changed in: lightdm (Ubuntu) Status: New => Incomplete -- 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/lightdm/+bug/1821609/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

okay a previous "fresh install that was crashing plymouth screen/lightdm/xorg was fixed by copying a known working set of netplan conf files into /etc/netplan .. the 01-netcfg.yaml from the "network install" uses networkd as the renderer .. with a working network device config.. plus the 01-network- manager-all.yaml file as well proof enough? of some weird interactions between services now the minimal 01-network-manager-all.yaml on the new installs seems to be lacking something .. although the documentation says it should work .. which it does if your graphics start properly .. Wayland (ubuntu install) or amd/ati cards probably nvidia too I have not tested but if using the current default netplan and i915 as module NOT listed in /etc/modules .. it does not work it crashes and locks up and only a powerswitch shutdown works .. no reset button on laptop .. no console access is available either .. so it has taken a bit of time to determine all this .. Anybody know how to fix the netplan config in a "generic way" to cure this issue? the only problem is no control over switching networks ..

okay I stumbled across something .. the network install .. used netplan to set-up my wifi connection to start on boot .. so as soon as systemd networkd starts wifi is started NetworkManager thus has no access or anyway to try for other networks.. so I tried to change this.. If I edit the config files to give exclusive control to NetworkManager ..run netplan apply as long as I don't reboot I can use NetworkManager as per normal As soon as I try to reboot back into the install (via and foreign grub as defined above) I get exactly the same crash pattern as before .. so the deduction is that netplan configuration problems are causing the plymouth/xorg issues when you use only NetworkManager as a renderer .. so I am altering the title here again ** Summary changed: - lightdm login screen briefly appears and then blanks out on Intel(R) Core(TM)2 Duo CPU T5870 (crash in xorg before using "foreign grub") + lightdm login screen briefly appears and then blanks out on Intel(R) Core(TM)2 Duo CPU T5870 (crash in xorg before using "foreign grub") netplan mis-configuration maybe underlying cause. -- 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 (crash in xorg before using "foreign grub") netplan mis-configuration maybe underlying cause.

here is the journalctl boot log for sda6 /zlink4 booted by it's own install of grub (self grub) (it was reinstalled for this purpose .. to show it works .. however plymouth does not show on the screen at all on boot but does on shutdown ) now one change is addition of a vt.handoff=1 to the end of the grub entry (originally a $vt_handoff) i'll shortly revert this and regenerate this log again.. size is about same as zlink1 version also about 1 minute long note every problem boot has a much shorter journalctl boot log..why? some stuff is not getting done .. only because the source of the grub- install has changed and the controlling partition grub.cfg used instead .. ?? these are generic auto-generated by update-grub .. so why the different behaviours ** Attachment added: "zlink4 / sda6 boot log -- self grub boot" https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1821609/+attachment/5252840/+files/zl04-apr-4-sgrub-currentboot.log -- 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 (using "foreign grub") To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1821609/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

so why the peculiar behaviour that lightdm works when the partition installed native grub boots the system BUT not when a grub installed by another partition is used then lightdm consistently crashes and the machine locks up.. BUT if i915 is added to /etc/modules in the offending partition it all seems to work properly .. except plymouth does not show up.. if grub is restored by the offending partition via booting via rescue or working through a chroot WITHOUT i915 added to /etc/modules i.e. as installed originally .. the system seems to work but some times only vesa is used after an initial lightdm crash .. Then there is partition sda1 which consistently works from any grub installed by other partitions and NEVER had i915 added to /etc/modules .. please explain...what might cause this -- 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 - failure to load i915 kernel module To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1821609/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

a little digging and plymouth is supposed to work with drm modesetting drivers which means i915 has to be loaded for it to work .. so not seeing it means ..some hardware detection has failed .. is that part of plymouth or something else? since it works on the upgraded install on sda1 I suspect a config file change relating to hardware detection and "autoload" by systemd .. i'm not familiar with that magic ..

Kernel module will load if added to /etc/ modules .. I have my sda1 partition running kernel 5.0.0-8.9 as are the iso's tested recently .. my sda1 partition loads i915 without using /etc/modules..

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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

okay still bug present in xubuntu-disco-amd64-desktop-beta.. still uses kernel 5.0.0-7 updating from proposed with kernel 5.0.0-8.9 it works properly i.e. any linux os partion can be used to install grub and another partion with linux can be selected and boot normally e.g. beta install is on sda7 another linux os version is on sda1 which is used to install grub to /dev/sda thus sda1 is master/main linix os used .. the beta on sda7 will start lightdm but it flickers on and dies when using kernel 5.0.0-7 but when using kernel 5.0.0-8.9 it works properly lightdm stays running and does not even flicker... the only apparent difference is the kernel selected .. -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

*** This bug is a duplicate of bug 1819943 *** https://bugs.launchpad.net/bugs/1819943 addional clarification .. if sda6 (recovery booted or chrooted) installed grub then sda6 boots with some brief flashing normally. if sda7 or sda1 (recovery booted or chrooted or a normal boot for sda1) installed grub then sda6 would boot and lighjtdm would briefly flash onto screen and the disappear (blank screen) showing just aflashing underline cursor. so xorg video drivers appear NOT to be involved. except maybe as kernel i915 modules missing I have not checked -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

*** This bug is a duplicate of bug 1819943 *** https://bugs.launchpad.net/bugs/1819943 this effected only the more recent installs you have miss understood the details in the initial report .. the system would boot normally as long as the grub used (installed) was from the install partition (sda6 or sda7) .. if another partition was used to install grub the lightdm would appear briefly and then crash or vanish to a underline flashing cursor the video system did work it would flash once on start-up but come back in about 5 seconds or less is the correct (ie this partition installed the grub version used) the main sda1 partition always worked .. only difference was the kernel image used .. I have not yet checked to see if the sda1 5.0.0.7 image fails currently but it worked fine before. the installation of the newer video drivers did not fix this issue!!! It remained as long as a 5.0.0.7 kernel was selected to boot sda6 or sda7 sda1 was not effected. -- 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
