External monitor stopped working after upgrading tumbleweed

English Hardware
1

I upgraded tumbleweed this morning, and after a restart, my laptop no longer connects to my external monitor. My laptop was able to connect to the monitor before using mini display port connection.

I looked at the thread here: https://forums.opensuse.org/showthread.php/539833-tumbleweed-doesn-t-work-with-me-external-monitor. This thread does not seem to apply to me because i do not have INVIDIA GPU.

Here are some info about my system:

Any hints on how to solve this problem is appreciated. I am not an expert on linux so please take it easy on me.

Does the problem remain if you boot the prior kernel?

Have a look here, then try switching to the modesetting display driver to see if it makes any difference.

I have two Haswells, neither a laptop. On neither have I installed a 5.16 kernel yet. This is from the GT1, which is primarily used only for testing:

I created this reply mostly to show a Haswell can currently run two displays on TW.

My Haswell GT2 is the PC I’m typing this on, booted to 15.3. I only boot TW on it when urgently needed, which I might do later if it looks like it could help solve this OP’s problem.

I booted up the system with the old version (5.15.12-1-default) and it has the same behavior: my external monitor does not work with it.

I did follow the link you sent (xorg-x11-driver-video and xf86-video-*) and I still have the same issue.

Do you have another HDMI cable to try? IME, too many HDMI cables go bad. Is HDMI what you’re using for the external display? Are you using any kind of adapter to connect the external display?

Now that you’ve switched from the intel DDX to modesetting DIX display driver, Xorg.0.log will report connectors. The intel is the only DDX I’m aware of that doesn’t. Does it show the external display is connected?:

grep onnec /var/log/Xorg.0.log

or

grep onnec ~/.local/share/xorg/Xorg.0.log

Alternatively:

xrandr | egrep 'onnect|creen|\*' | grep -v disconn | sort -r

will show what X thinks is connected. Your Xorg.0.log isn’t showing the volume of EDID info I’m used to seeing, and it’s only coming from apparently the laptop display.

I suppose this could be a Gnome issue, so try opening some other session instead to see if same problem there, e.g. IceWM is normally installed as a convenient option. If that has the same problem, report a bug and include a link to this thread. I think it best to try another display cable first though.

The problem is resolved.

I got a new DisplayPort cable, but that did not solve the problem.

In a very strange way, the problem was resolved when I logged out and logged in in LXDE twice. Then all of the sudden the external monitor worked. I did that twice with GNOME, and now the monitor works.

I am not sure if there is a way to check if I am running in modsetting driver or not. Here is the output after using my monitor after turning off my laptop screen.

and

All those modeset(0) lines are the modesetting driver reporting things it finds, does or tries to do. inxi -G reports both the kernel driver in use and the display driver in use.
