2nd display stoped working


Hi guys,

I am a bit confused here. My laptop worked realy well with two additional screens, but stopped it since I've booted the thing this morning. Now I can only chose between one of the external screens. I connot use both at the same time. They both work fine, but not together.

Laptop: Fujitsu Lifebook with dockingstation
Screen1: Asus 27" - connected with DP
Screen2: Asus 24" - connected with DVI
Distro: MX Linux - up-to-date

Working and not working cases:

C1: 27" + Laptop - works
C2: 24" + Laptop - works
C3: 27" + 24" - nope
C4: 27" + 24" + Laptop - nope

Like I said initially, C3 and C4 worked fine until yesterday.

I've searched this forum for similar problems and could find nothing, but saw, you guys like to have informations from xrandr:

Code:
$ xrandr
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 16384 x 16384

Are dock and both external displays powered on when booting the laptop?

Which DE or WM are you using? Is the behavior different if you start a different X session type, or use Xorg instead of Wayland (or vice versa)?

Is it possible to connect both external displays without using the dock? If yes, do both external displays work at the same time?

Were any updates installed before shutting down yesterday? If yes, were any related to graphics, or a new kernel?

Are there any new or freshly changed files in /etc/X11/ or /etc/X11/xorg.conf.d/?

Please ensure /etc/inxi.conf does not contain B_ALLOW_UPDATE='false', removing the line or changing false to true if necessary, then run sudo inxi -U, and follow by pasting here input/output from inxi -SGaz -vs.

Positive. Both ASUS displays have it's own power source and they are powerd before I boot my laptop.

Never done, don't know how. Need to learn it and will report back when done.

I've tried following:
I've connected the 27" display directly via DP to the laptop and the 24" display via DVI and docking station.
Both displays work now like before the problem occured, yet not fully with the docking station, which is unsatisfactory.

I am not sure. I update like Lucky Luke - faster than my shaddow - maybe not a good idea ^^

Ether one of your measures worked, or the problem was simply solved by using another DP-Port at the docking station.
Booted several times - removed and replaced the laptop from and to the docking station several times - the display settings are working again and they are stable.

Whatever it was,it works now perfectly.

Thanks for your help @mrmazda

Looks like you had an encounter with connector voodoo. Glad it works now!

I also allowed to update, like you've suggested "/etc/inxi.conf does not contain B_ALLOW_UPDATE='false'" and made an update.

But I am to new too Linux to even understand what the inxi.conf is for =D
So my guess is, it was the connector voodoo.

Thx again

Did you misspell inxi when you were supposed to run inxi -U, or just here in your #3 response?

Quote:

What it is for is like any .conf file, so establish an/some configuration option(s). In this case, it was to prevent successful use of the -U switch, and keep you using a broken old inxi version. We wanted your inxi output here from the current inxi version, so changed that option to allow the upgrade by changing false to true.

Inxi has/had nothing to do with your graphics connectors issue, only with the information contained in inxi's output/report.
