HDMI Connection cause logout from System

English Hardware
1

Hi all Members,
I’ve recently changed my operating system from deepin to tumbleweed. I’m thrilled. It gives us so many functions and possibilities. One problem bothers me a lot, my external monitor connection. Every time (after log in) when I plug-in my HDMI cable from external monitor to my laptop - black screen appears with weird characters “@@@@@”. After I click any button on keyboard, Tumbleweed avatar appears and starting log-in to system again. Of course all my processes were killed and I need to start over opening them. It’s very annoying! Same thing is happening when i plug-out my HDMI cable. The situation doesn’t appear when I remove/plug-in cable again (only once after running laptop). Apparently, I need to change my video driver somehow. Does anyone got the same problem or know the solution for that?

Hi and welcome to the Forum :slight_smile:
Perhaps some details on the desktop in use (Wayland or X11) and the graphics hardware, so as your user run;


/usr/sbin/lspci -nnk | egrep -A3 "VGA|Display|3D"
echo $XDG_SESSION_TYPE
xrandr

HDMI is not compatible with a hotplug - you may burn out your HDMI ports.

Thanks guys for fast response! :wink:

What do you mean by saying “burn out your HDMI ports”? Its a normal thing to unplug/plug-in HDMI cable to laptop, its perfectly normal to do this on other operating systems like Windows or MacOS or even other linux distro.

Hi
My bad;


/sbin/lspci -nnk | egrep -A3 "VGA|Display|3D"

Hi
Ahh, so dual gpu’s… on the other operating system did you run the likes of the nvidia driver, suse-prime etc?

Sorry, haven’t checked when i had other systems. If I have dual GPU’s it will be a problem of using my laptop somehow? I ve used other OS with standard configurations and works good (had Win 10, Elementary, Deepin). What I can do about that?

Hi
So on the other Linux operating systems, were applications likes bumblebee, prime or perhaps vgaswitcheroo installed?

10

Before I’ve installed Tumbleweed, I had many other Linux OS. Every time HDMI connection works perfectly, what can I do about this now? Installing other OS now for testing isn’t the best thing to do after works… Is it possible to switch off one graphic card, change drivers etc to check is a problem still exists?

Hi
Does it reproduce if you switch to using Xorg rather than Wayland?

12

Yes, problem not exist now, but creates new one. After changing brightness, its starts lagging (screen or movies freezes while doing it).

Hi
The system is all up to date with the latest kernel/snapshot using zypper dup?

If so, then some regression which probably needs a bug report (Please post back the report number :wink: ).

Hi,
this is very risky command to execute, ask many questions about replacing some drivers, I am not sure what should I choose to run this Thumbleweed correctly. Is there any tutorial to set all drivers, so operating system starts working propertly?
Thanks for all your efford malcolmlewis :slight_smile:

Hi
Then how have you been updating the system, zypper dup is the ‘correct’ way to use Tumbleweed, nothing risky about it?

You mean replacing (in some cases downgrading) packages?
