lubuntu mantic daily - 2xgpu's & only primary is now utilized by desktop/UI

[Chris Guiver]

This was noticed two nights ago on my installed mantic system after I rebooted.

It occurs regardless of desktop (thus my filing against Linux), however NOTE this package is likely a misfiling as I have NOTED NO LINUX changes...

On booting yesterday's mantic daily (lubuntu) I noted no change with my five attached screens working as expected; 3 connected to primary i915/intel & 2 connected to radeon. On this daily however I'm only able to use monitors connected to the i915/intel working.

** What I see on boot (live & my installed mantic system on this box)

1. On boot; plymouth appears on all 5 displays; today & prior mantic ISOs

2. At greeter/dm (sddm) I get to view only i915 on my installed system; this is NORMAL behavior SO NO CHANGE. This step isn't seen on this LIVE ISO boot; but noted on my installed system.

3. Once logged in on my installed system I can view only using the i915 connected monitors; the 2 connected to old radeon card go into sleep mode. I noted this two nights ago on installed system, this is the FIRST DAILY ISO that exhibits that behavior.

** Expected behavior

Steps 1 & 2 are normal, at step 3 though; when system is booted & operational (I'm logged in), I expect to be able to use all five of my attached monitors.

** Actual behavior

On displays connected to intel card now work; If I go into settings etc; only the first 3 displays are configurable. The two connected to radeon card don't exist in settings thus cannot be 'enabled' (this was sometimes required on new installs/live boots).

Operation on DAILY ISO today matches what experienced on installed system yesterday & after boot the two nights ago.

** DAILY ISO changes

A DIFF between today's DAILY ISO manifest & the last I booted (2023-07-29) that didn't exhibit this behavior shows the following changes

is this thus related to pci.ids ?? Sorry I don't know.

This occurs on my installed system using other desktops too, I'll zsync the Ubuntu Desktop ISO (when I can) and expect that behavior today too (given the same behavior occurs on GNOME on installed system).

Of no value I suspect, on shutdown the plymouth & eject messages appear on all monitors...

Linux can't be involved due to it working at plymouth (boot & shutdown).. the issue is elsewhere in the stack, but sorry I don't know where (thus the manifest diff)

Exploring with current Ubuntu Desktop ISO, and no problems.

http://iso.qa.ubuntu.com/qatracker/milestones/446/builds/283569/testcases/1743/results

pci.ids 0.0~2023.05.23-1 is in manifest (difference to lubuntu mantic daily)

[Chris Guiver (guiverc)]

Exploring again with current Ubuntu Desktop ISO, no problems

pci.ids was updated on this ISO for Ubuntu Desktop thus its not that.. (couldn't see how it was fault anyway; it just showed up as changed on my lubuntu manifest diffs) thus that is INVALID

Is this something Lubuntu specific? package on Lubuntu ISO??
that was thus on my primary mantic install (which has ubuntu-desktop + lubuntu-deskop + xubuntu-desktop) which caused by install to be impacted; it's not impacting LIVE

[Chris Guiver (guiverc)]

I just experienced this today on 22.04.3 daily???
- dell [optiplex] 7050 (i5-6500, 16gb, intel hd530/i915, radeon cedar)

http://iso.qa.ubuntu.com/qatracker/milestones/429/builds/283826/testcases/1303/results/

this was unexpected; I'd not noticed it on the installed system (will boot & explore that shortly!) though I've used it less recent days.

I also don't recall this issue with jammy on live ISO before; alas when did I last test on this box? I've mostly booted live on other boxes

(i rebooted [into] my [installed] jammy system & all five displays are working; upgraded packages & rebooted; still good .. though it looks like daily is built with -proposed packages (not on my installed system))

i booted 20230801 ISO on this box; issue occurred yesterday's ISO too

I booted Xubuntu mantic daily on 3070 (http://iso.qa.ubuntu.com/qatracker/milestones/446/builds/284361/testcases/1303/results/) and whilst the monitors attached to the second display card (4 & 5) were disabled, they were easily enabled & put into operation.

This problem appears to be LUBUNTU SPECIFIC.

I booted into my installed system, and was unable to enable display 4 & 5.. in the Lubuntu Monitor.Settings only 1-3 are configurable in that option..

On logout (installed mantic) system, and switching to Ubuntu Desktop (GNOME) I can use all displays (this was GNOME on Wayland!)

Is the issue only that I need to 'enable' the displays in LXQt, and there is no simple/easy GUI option for that in Lubuntu?

Logout & switch to Xubunu/Xfce.... I see only display 1-3 configurable like I do in Lubuntu.. which differs to the Xubuntu daily ???

It feels like a Lubuntu configuration issue (why it appears on daily run live) makes the Xubuntu act this way.. and I need to find it. Ubuntu Desktop & Xubuntu Desktop run in live allow me to use all five displays.

[Chris Guiver (guiverc)]

booted Lubuntu mantic daily 20230811 & i can use all displays...

this maybe is a SUPPORT ISSUE & consequences of mantic (development) usage, and no actual bug that needs fixing !!! ??

(I can't say all is working as expected, but my issues now relate to different bugs relating to openbox, and not related to this issue!)

Changing the Lubuntu issue to 'incomplete'

[Chris Guiver (guiverc)]

If i login using Xorg with Ubuntu Desktop; the displays attached to the radeon card are DARK.. (except during the plymouth boot/shutdown sequence)

They're now working only in Ubuntu Desktop (Wayland) as mentioned in comment #7, however Xubuntu/Xfce and Lubuntu/LXQt use Xorg... and it's not working when I login using GNOME & Xorge either.

Something changed (leading to this bug report) which made it work in Wayland only? but that's NOT a Lubuntu-META package issue, no idea what the report should be filed against though sorry.

[Chris Guiver (guiverc)]

I wonder if this issue relates to https://launchpad.net/bugs/2031361 (Xorg crashed)...

The issue with 2031361 (Xorg) has happened twice... alas I've been unable to re-create it since (and more than 10 attempts, 6 with same ISO & 2 subsequent ISO too)

[Chris Guiver (guiverc)]

Whatever this issue was occurred for a number of days when testing the LIVE media (ubuntu/lubuntu mantic dailies) HOWEVER that changed with time... Now I only need to ENABLE the radeon connected displays & they operate (lubuntu) when booting LIVE media.

The issue however remained on the installed system.

Ubuntu mantic has now been re-installed, and issue does NOT occur on installed system now (talking about my primary box
