HDMI doesn't work after last update

Hi all! I’ve just updated the system with ‘zypper dup’ and the HDMI monitor doesn’t wokr anymore. Anyone can help? Thanks

All local clairvoyants are on vacations right now.
Others need info about hardware and drivers to provide any help.

What does “doesn’t work” mean? Does any other graphic output work? Please run sudo zypper in xdpyinfo inxi and then provide here input and output using code tags from a Konsole, Xterm or equivalent running

inxi -SGay
cat /var/log/Xorg.0.log | susepaste

If you use an Nvidia card and updated the driver to 470-74 it may be related to this issue

This bug has been fixed internally and will be resolved in upcoming releases.

Hi, when I connect the cable nothing happens on monitor and nothing happens on laptop, seems the laptop “doesn’t know” I’ve connected something.

This file doesn’t exists: /var/log/Xorg.0.log

Hi, I’ve got an Nvidia card, but I’m not using Nvidia drivers

Gnome users may find the file ~/.local/share/xorg/Xorg.0.log instead of /var/log/Xorg.0.log. If you don’t find it there either, check to see if either location has one with a number in the name other than 0, and if so, susepaste it instead.

After you plug the cable, try keying in Ctrl-Alt-F3 followed by Alt-F1 or Alt-F7. Does this wake up the display on HDMI?

Key shurtcuts don’t work, but the Xorg log was where you said, so here it is: SUSE Paste

Those keys must be struck as a unit, in short succession, function key last, effectively all down together, before they will work. If they do not, it is a bug that needs to be reported.

I don’t recognize any material problem in the log. It does contain (EE) open /dev/fb0: Permission denied, which I don’t recall ever seeing before. Its location suggests it’s not related to your issue.

Hi, I’ve opened a bug report, thanks for help
