Missing Monitor on Login

English Install/Boot/Login
#1

Running Tumbleweed. Recently upgraded in late June 2023, and again 20230707.
Also upgraded this dual boot PC to Leap 15.5 from 15.4, in late June.

Integrated Graphics RS780L (Radeon 3000) - radeon driver
Discrete GPU RX560 - amdgpu driver
sddm
kde plasma with X11

Before:
All displays and monitors show and configurations save

4 monitors
Left - Center - Right
Under

Left is driven by the Integrated HDMI port
Center (HDMI), Right (DVI) and Under (DP - HDMI) are driven by the Discrete GPU card

Left was rotated 90 right and Right was rotated 90 degree left

After: Issue Started in Late June
Issue 1) Only 3 monitors show
Left is missing (Integrated graphics)

Issue 2) Right Monitor will not rotate
tried to use xrandr output, but it fails
something like invalid transformation…

I read in a forum that amdgpu must load before radeon. If so, how is that done?

The ‘Missing Monitor’ does show on the boot screen - all 4 monitors show the boot screen and the ‘Tumbleweed’ Logo, then when the Login screen displays, the 4th Monitor (Left) disappears (no display).

Any ideas on how to get the Integrated Graphics monitor to also display in KDE?
It displayed OK, until recent upgrades of Tumbleweed.

#3

Old Radeons of your elder’s vintage seem to be suffering regressions lately, likely due to developers not using such old hardware any more. I recently reported two: Mageia bug 32066 and Redhat bug 2220717. I haven’t found a problem with any of my old Radeons on TW, yet, but I’ve never tried to use two at once either. Your issues could be fallout of whatever seems to have gone wrong as manifested in my reports.

Please, whenever posting command output, enclose it in PRE tags (</> icon above input window), and include both the full command line itself, as well as the following shell prompt, so that we have full and readable context of what you’re presenting.

Another bit of command input/output, run from Konsole in TW, should be helpful: inxi -GSaz. In Leap, inxi is an older version that may include some -G brokenness.

#4

Also, a reinstall of tumbleweed helps in the most cases, I did update to 6.3.7. and 6.3.9.1 in both times the 2 GPUs stopped working, together, if I installed nvidia, but returned after a fresh install of Tumbleweed.
A simple snapper revert does not work for me.

regarding the monitor orientation, there an some issue,

I do use horizontal screen when I am mobile and and also
multi GPU screens.

The issue with many distribution is actually, that you have to watch out for the correct numbering of the monitor output.

I still have a eyefinity 6 radeon 6950HD in the office connected to 6 screens.

You are not free to choose a random mix of screens.
Not possible:
1 4 2
6 3 4
To get this running I can only do
1 2 5
3 4 6
Other placement will crash the driver.

Now with my radeon 4600H + nvidia 1660ti I just experienced the issue again
I cannot place
3 2
1 [notebook screen]
I must place them
1 2 3 or

2 3
to get them to work.

The missing orientation also seems to be a returning bug,
Try if you can rotate neighbouring ports, to change

Also, a working workaround, to only use the discrete GPU is to get a DP MST adapter, like the one here, DP to 2x DP or 2x HDMI,

#5

And actually

if you need multiple screens, I fully and finally ended my request for more screen estate, by switching my
6x 22" 1080p screens against 2x 4k 43" screens. Enough space for everything, and mostly no issues with graphics drivers.

Device 1 is the card that does NOT display

Monitor-1 is the monitor that will not rotate.

Everything worked until last month.

#7

cik_support options are supposed to apply only to Sea Islands GPUs, which are GCN-2 and not what you have. I would try removing those options from your Grub linu line. I’m not sure whether those options continue to be supported or necessary at all in recent kernels.

Current TW version in OSS repo is 23.1.3, so maybe another dup will help.

This is the older (2008) card.

Using which kernel? Is that kernel still installed to try?

#8

I removed the cik_support lines - no change

The MESA version may be locked due to steam, will double check, but just a simple display should not be impacted by mesa

I do not have the older kernel still available…

Not a big deal.
It was great while it lasted.

I will get by with the 3 monitors on the GPU card.

Maybe later this year get a new MB and GPU.

Will try a fresh TW install next.

So, there could be a fix to be found if you report this as a regression bug.

You might try first disabling KScreen2 in Plasma startup, then manage displays manually via xrandr/arandr. Upstream 5.26 had a lot of changes regarding multiple displays because of a multitude of multiple display bug reports, that have since kept on coming in 5.27.

#10

SOLVED.
Had to Unlock ALL Mesa updates, that would not previously update due to Steam dependencies?

The Mesa packages are from Packman. I cannot even remember why I needed the Packman repos.

After 2 more updates, everything is now awesome once again, as Tumbleweed, normally is!
