Sudo should be used with inxi only if using the -U switch, and a select few others, -Gaz not among the exceptions. Otherwise, it holds back information.

The inxi output previously failed to detect the full HD resolution with the modesetting driver, but that and the above collectively do not suggest anything helpful. Please do the following for a boot on which nomodeset was not used to boot, and provide the resulting URIs here:

cat /var/log/Xorg.0.log | susepaste -n sergelli
sudo dmesg | grep -iE 'fail|modeset|intel' | susepaste -n sergelli
sudo journalctl -b | grep -iE 'fail|modeset|intel' | susepaste -n sergelli

Any could possibly provide a clue as to what’s going wrong.

Did it change anything at all about the displays? If not, I think this is a bug that would be worth reporting if if wasn’t so close to time for support for 15.3 to cease. It only has around 7 weeks to go. If you upgrade to 15.4 and it fails to work correctly too, then a bug report would be much more likely to get fixed, IMO virtually certain.

OTOH, I have a much newer PC with a similar 15.3 problem that has no such problem with 15.4. If a report were to be filed and bug confirmed to apply to both yours and mine, it might get fixed despite the short remaining support period. The similarity between yours and mine, even though their difference in age is huge, is that our black screens are using DisplayPort connections, yours internal and named eDP-1, while mine external named DP-1. On mine, the problem does not occur if I only use two HDMI ports instead of one DP and one HDMI. My problem isn’t new, but it has newly worsened to more closely resemble yours in result and timing. To put it short, a bug may exist that applies only to DisplayPorts in use in conjunction with some other graphics output type.

I left out parameters necessary for the pastes to remain longer than an hour. Redone:

cat /var/log/Xorg.0.log | susepaste -n sergelli -e 40320
sudo dmesg | grep -iE 'fail|modeset|intel' | susepaste -n sergelli -e 40320
sudo journalctl -b | grep -iE 'fail|modeset|intel' | susepaste -n sergelli -e 40320

40320 corresponds to one month. Alternative time periods are available in man susepaste.

Good morning my good and dear friends.
Today I created a new user
I restarted without the “nomodeset” inside the boot
When uploading the new user, OpenSUSE is working perfectly.
But when I log in as my primary user the problem continues.
What should I do to resolve it?

25

I don’t understand what you want me to do.
In any case, I ran everything in a terminal
Here’s the result:

New user working correctly says it’s a problem with your user profile. First thing to try follows:

  1. log out of your normal user
  2. Ctrl-Alt-F3
    (to switch to a virtual terminal)
  3. login as your normal user
  4. rm .cache/*
    & confirm deletion of content of your cache directory
  5. Ctrl-D
    (log out)
  6. Alt-F7
    (return to GUI login screen)
  7. login to check if it helped
    *]report back here

Hello
Doing Ctrl+F3 and login
I ran “rm .cache/" and there were many directories left
So I ran "rm -r .cache/” and everything was deleted
Then I typed Alt+F3, but nothing happens, so I restarted.
Nothing has changed, the HDMI cable still doesn’t work and when I use it, the HDMI works but a lot of things don’t work
My God… how difficult it is…

Alt-F3 was not the return to GUI instruction. :stuck_out_tongue: To leave the GUI requires a three-key combination. To return only requires two, the correct two, which is usually Alt-F7. F1-F6 are usually fullscreen text logins. Some configurations have the GUI on F1 instead of F7, while some others have it on F8 or F2. F1 has a nominally unique configuration in any event, so I never suggest it. These exceptions are why I suggest Ctrl-Alt-F3.

Plasma’s config files are contained in ~/.config/, mixed among config files and directories for many other apps. You can selectively delete the ones that appear to be for KDE/Plasma while logged out of Plasma, then return to check for success, and to see what settings were lost.

From the fullscreen text terminal Ctrl-Alt-F3 produces, the Midnight Commander OFM mc can be used to select and delete easily within ~/.config/. As an alternative to a fullscreen text session, you could login to an alternative GUI session type from SDDM/LightDM, such as IceWM, but you risk involving the very files you wish to remove if you try to use e.g. Dolphin for selecting and deleting. Mc can be run in an Xterm in IceWM to avoid using any of KDE. If mc is not found, do sudo zypper in mc and try again.

29

I performed the steps to delete suggested folders and files whit the .cache/ command* with success, but nothing resolved
If I don’t use the “nomodeset” command at startup I’m having several problems, which don’t happen with another user,
Does anyone know how to solve this?
Will I have to reinstall OpenSUSE?

Genyoutube download photo is your best destination and site for downloading videos from the web. It is compatible with multiple online websites and works at a super fast speed. You can download various songs and music files from SoundCloud and other quality sites like YouTube without any hassle directly in your desired format.

31

You already did that before. .config/ in comment #28 is different, not cache, but personal settings. Removing all files there will in effect make you a new user if you remove them all, which you don’t want to do except as a last resort, because it will remove settings for most apps, not just KDE/Plasma settings.

32

I do not understand!!!
I did it: Ctrl+F3 and login I ran “rm .cache/" and there were many directories left and I ran "rm -r .cache/”
So, **everything was deleted **
It didn’t make me a new user and it didn’t remove any app settings.
So I keep having to use the command “nomodeset” on startup to get a lot of things working again.
After all, is it possible to go back to having the default settings of an existing user?

33

Note that the above is about a different directory than the instructions in comment #26. These are what to do if the instructions in comment #26 failed to help.
