[radeon] jammy live - on adjusting display config; one display is unsuable blocky-mess

[Chris Guiver]

ubuntu jammy daily (canary build) live test on
- dell optiplex 960

(this is my primary machine; so is normally used for entry of data & not doing the QA-testing).

on adjusting the displays to match my setup (six displays; two high & three across; this box uses two in the middle with middle on top row & middle on bottom row).. the top display is still useable, but the bottom is not. This boxes are not perfectly aligned as not all my displays are the exact same size; so top display is slightly to right of bottom display

the bottom resembles a digital TV with bad signal, mostly blocky & parts of it flashing (very quickly). it doesn't match the attached picture (as viewable on this box anyway.. my top display; which was LEFT prior to alignment is perfectly readable).

** actual

my top display is usable, bottom is not (blocky warped picture)

** expected

on adjust displays to match my config; both displays remain usable & readable.

** notes

likely related to graphics card & not GNOME. If I recall correctly; this box has an older video card used as it had 2x DVI connections my screens use.

My usual install on this box is jammy; but I usually use LXQt/Lubuntu and I don't experience issues.. I also have installed Xubuntu/Xfce & Ubuntu/GNOME so can test the installed OS (where I don't believe I have issue), but my install is somewhat old (artful install upgraded every six months ~30-36 hours after each release) thus is likely heavily modified.

** Picture comments

My top display is ~perfect (vertical white bar to left of ubuntu-dock-items I'd not expect, but the color-blocks to the left of the 'install/firefox/thunderbird/files` is NOT visible; only a vertical WHITE bar a few pixels wide to left of the dock appears' rest of top display is perfect.

My bottom display is nothing like picture; it's unusable. A mixture of black/white boxes with red/purple bits which would be the picture warped into blocky-components. When I type, I get reactions on this display with the picture changing (mostly the black & white portions which flash, the red/purple bits which are warped indri picture appear to remain static).

My phone/camera isn't working, but I've taken a photograph. I didn't anticipate issues in this QA-test (it's past 1AM now) otherwise I'd not have run this QA-test now.

** further comments

this is likely a duplicate... I experience this type of reaction on other boxes; likely radeon related but I've yet to look & can't even remember which video card exists in this box (I don't experience issues with the display configuration of the box with identical card to this, but it relates to display setup/config... my other box with this card is landscape+portrait I believe and doesn't have one display above the other; ie. d780; I get these issues when one display is above the other - and only with single orientation (swap top/bottom and issues don't exist))

so this is with X, what about the wayland session which should be the default?

[Chris Guiver (guiverc)]

I haven't re-tested on my primary box (d960)... yet.

I grabbed the latest *daily* of Ubuntu Desktop (2022.02.16) and performed a live QA-test on

- dell [optiplex] 780 (c2q-q9400, 8gb, amd/ati cedar radeon hd 5000/6000/7350/8350)

and was unable to re-create this issue. Default session on a LIVE run is X.Org as reported using GNOME.Settings.ABOUT which is what I believe was default on d960 (and am yet to confirm).

Do note it's identical in specs except for box model; my details being taken from `lshw`. HOWEVER it has different motherboard & external ports, and its video card has HDMI+DVI ports out the back instead of 2xDVI on the 960 thus its not identical. It also has different resolution monitors (two old dell 4:3)

I could NOT re-create the issue described in this bug report on this box; including play trying to adjust screen positions in arrangements somewhat akin to how monitors are set on 960 (much of the play using the landscape+portrait orientation as that's how the 780 monitors are; which is different to 2xlandscape on 960, but I did try and re-create using 2xlandscape [gritting my teeth]

I've booted today's daily (jammy canary ISO - ISO date 20220222) on my
- dell [optiplex] 960 (c2q-q9400, 8gb, amd/ati cedar radeon hd 5000/6000/7350/8350)

On FIRST adjustment of displays (one [directly] above the other) no visual issues were observed.

On SECOND adjustment of displays (top display slightly to the right of the below display; this is how my displays actually are as not all displays are identical size), visual glitches did occur - however they don't match the description of my original post.

My bottom display today is PERFECT, the glitches appeared top display along the left edge only.. but they've since returned to normal (glitches stopped flashing after I took screenshot). I've noted this behavior BEFORE many times (mostly with UBUNTU-MATE many releases ago), but before this box became my primary one, it was used for QA-testing far more regularly than it is in recent releases.

See screenshot - it'll explain how I've aligned displays PLUS shows ~blocky-mess where screens do not show (left of my-top display & right of my-bottom display.. this POSSIBLY is what I was seeing on original post EXCEPT it was showing on screen but isn't today at least not now (but was left edge of my upper screen at beginning of session after second adjustment of display settings until I hit printscreen).

GNOME Settings About - tells me X11 is the "Windowing System" used in this default run.

Either way; nothing would stop me from using this box today... (I may [if i remember] when I reboot into my normal jammy] use GNOME & have a look at how it is there

I did NOT find a way at gdm3 to login using WAYLAND instead of default X11/Xorg in the live session.

(I'm not going to report this bug on QA-test; it's not bad enough as only an extremely mild version of what this report was like; my QA-comments can be found at http://iso.qa.ubuntu.com/qatracker/milestones/429/builds/244757/testcases/1743/results)

On rebooting into my installed system on same box
- dell [optiplex] 960 (c2q-q9400, 8gb, amd/ati cedar radeon hd 5000/6000/7350/8350)

AND using 'Ubuntu on Xorg' (sorry i forget exact wording) on Ubuntu jammy.

- I am NOT getting any video glitches using the GNOME desktop; if I had I would have noticed before now

HOWEVER

- SCREENshots are showing issues to the left & right of what my scree showed just as LIVE image showed, these are only visible using PRINTSCREEN, and AFTER screen-position-change (even if change is very slight)

What I see varies on each SCREENSHOT but on the attached picture I see bits of the terminal window mostly; parts of my `gpicview` display of first picture (will talk about this shortly!) .. & other windows.

PLEASE NOTE the image shown in the `gpicview` window; nothing glitchy shows on that picture!! which was directly after login before I adjusted screens; the issues appear to be after moving alignment of screen .... on four subsequent PRINTSCREEN presses after slight changes of screen.alignment GLITCHES were evident a per top-left & bottom-right of the image itself.

I see nothing wrong on my displays, I'm talking about PRINTSCREEN images saved to disk that are later viewed in my old gpicview.

Note: this installed system was installed in the artful cycle; is release-upgraded every 6 months (though wasn't on artful long at all) so is heavily modified.

This is my observation of this session only; I'd want to confirm what I wrote here on subsequent logouts/logins before I relied on it.. (QA-test installs & other stuff going on at same time currently)
