Dual head monitor stopped working after last Deepin upgrade

[arlequin8]

Disclaimer:
First of all, I do know Deepin is not a currently supported DE. Period.

Said that, we must admit there’s a lot of people working packaging and tuning the Deeping DE for us users to work in Manjaro despite its unsopported status.

Facts: I always managed to have a two headed display in Manjaro+Deepin using the Deeping Control Settings display section. So far, so good. Worked like a charm with a VGA connector and even with a mini DisplayPort (ThinkPad’s) adapted to a HDMI display.

Now, after last update, the multi-headed display is broken. It only offers my the option to “duplicate” my desktop and not to “expand” it. Even worst: changes my laptop’s 1366x768 resolution to a nasty old 800x600 one. I have to mention the VGA monitor supports 1920x1080 @ 60 Hz.

Any hints on this topic would be appreciated.

Welcome to Manjaro!

1. Please read this:
   How to provide good information
   and post some more information so we can see what’s really going on. Now we know the symptom of the disease, but we need some more probing to know where the origin lies…
2. An inxi --admin --verbosity=7 --filter --no-host --width would be the minimum required information… (Personally Identifiable Information like serial numbers and MAC addresses will be filtered out by the above command)
   Also, please copy-paste that output in-between 3 backticks ``` at the beginning and end of the code/text.

@Fabby

inxi --admin --verbosity=7 --filter --no-host --width

I’m pasting only the Graphics section, OK?

Actually makes no sense since my laptop resolution isn’t listed correctly.

Let’s take a look at

$ inxi -Fza

…before plugging the monitor that used to be 1920x1080:

Graphics:  Device-1: Intel Haswell-ULT Integrated Graphics vendor: Lenovo driver: i915 v: kernel bus-ID: 00:02.0 
           chip-ID: 8086:0a16 class-ID: 0300 
           Device-2: Chicony Integrated Camera type: USB driver: uvcvideo bus-ID: 2-8:5 chip-ID: 04f2:b39a class-ID: 0e02 
           Display: x11 server: X.Org 1.20.11 compositor: kwin_x11 driver: loaded: intel display-ID: :0 screens: 1 
           Screen-1: 0 s-res: 1366x768 s-dpi: 96 s-size: 360x202mm (14.2x8.0") s-diag: 413mm (16.3") 
           Monitor-1: eDP1 res: 1366x768 hz: 60 dpi: 112 size: 310x170mm (12.2x6.7") diag: 354mm (13.9") 
           OpenGL: renderer: Mesa DRI Intel HD Graphics 4400 (HSW GT2) v: 4.5 Mesa 21.0.3 compat-v: 3.0 direct render: Yes 

…so now I am getting the correct values:

eDP1 res: 1366x768 hz: 60 dpi

for my laptop screen, great.

…and after plugging the monitor

           chip-ID: 8086:0a16 class-ID: 0300 
           Device-2: Chicony Integrated Camera type: USB driver: uvcvideo bus-ID: 2-8:5 chip-ID: 04f2:b39a class-ID: 0e02 
           Display: x11 server: X.Org 1.20.11 compositor: kwin_x11 driver: loaded: intel display-ID: :0 screens: 1 
           Screen-1: 0 s-res: 1024x768 s-dpi: 96 s-size: 270x202mm (10.6x8.0") s-diag: 337mm (13.3") 
           Monitor-1: eDP1 res: 1024x768 hz: 60 dpi: 84 size: 310x170mm (12.2x6.7") diag: 354mm (13.9") 
           Monitor-2: DP2 res: 1024x768 hz: 60 
           OpenGL: renderer: Mesa DRI Intel HD Graphics 4400 (HSW GT2) v: 4.5 Mesa 21.0.3 compat-v: 3.0 direct render: Yes 

Please note: not only the plugged monitor “DP2” turned into a nasty 1024x768 square (it’s a 16:9 monitor, BTW), but the laptop itself changed its “natural” resolution.

Please, give me a last minute and take a look at the Deepin Display settings window: it used to be great, allowing me to duplicate or extend the display. Now the ‘Mode’ combo box doesn´t show any other option that “Duplicate” and the screens go crazy.

Sorry about my verbosity; I am trying to be a good poster and provide as many info as I can.

1. I’m on KDE, but asked you to provide more information so another Deepin user can efficiently help you

2. @arlequin8

   Sorry about my verbosity; I am trying to be a good poster and provide as many info as I can.

   You’re not verbose enough: a full inxi at least once would be more helpful as you’re on Intel hardware and those drivers are built into the kernel.

OK, Fabby. You’ve got a point. Thanks for your tip. Here it comes:

• You seem to have an older BIOS / UEFI version. Check if there are any upgrades. (can’t reach Lenovo site here, so can’t check for you)
• Try Kernel 5.4 LTS first and if that would have the same problem, try 5.12 Stable.

@Fabby

You seem to have an older UEFI version.

It seems my system does not supports UEFI…

$ sudo efibootmgr 
Swipe your finger across the fingerprint reader
EFI variables are not supported on this system.

$ ls /sys/firmware/efi
ls: cannot access '/sys/firmware/efi': No such file or directory

How could you relate my issue to UEFI? It’s something I pasted above?

OTOH, I’ve already tried with 5.4.116-1 LTS and 5.12.1-2 without luck…

[Fabby]

I’m so used to type UEFI instead of BIOS, that even when I think “BIOS upgrade”, out comes “UEFI Firmware upgrade”

I need

[arlequin8]

He, he, he. Thanks, Fabby.

You were awesome. Actually, my refurbished Amazon’s certified ThinkPad T440s needed some firmware update. The drivers were from March 2021 but the BIOS now shows July 2020 as the date.

Nevertheless, I did the update from the Windows Lenovo propietary binaries. No problem at all. But now I am running the Plasma Display Manager that works great with two headed monitors (VGA or HDMI-to-miniDisplayPort).

I really don’t understand what the hell happened to the Deepin Display Settings manager but I guess it’ll improve with time. So being an unsopported DE…

[Fabby]

I’ve marked this answer as the solution to your question as it is by far the best answer you’ll get.

Dual head monitor stopped working after last Deepin upgrade

You seem to have an older BIOS / UEFI version. Check if there are any upgrades. (can’t reach Lenovo site here, so can’t check for you) Try Kernel 5.4 LTS first and if that would have the same problem, try 5.12 Stable.

However, if you disagree with my choice, please feel free to take any other answer as the solution to your question or even remove the solution altogether: You are in control! (If you disagree with my choice, just send me a personal message and explain why I shouldn’t have done this or or if you agree)

P.S. In the future, please don’t forget to come back and click the 3 dots below the answer to mark a solution like this below the answer that helped you most:

so that the next person that has the exact same problem you just had will benefit from your post as well as your question will now be in the “solved” status.
