Desktop not working after boot

English Install/Boot/Login
1

Hi guys, i’m new in this forum since my professor installed opensuse leap 42.2 in double boot with windows on my samsung np900x3e, and installed a software developed by him to allow me working on my thesis, and it was all working ok.

this evening i had the stupid idea of installing synaptics driver from yast to modify some touchpad options. yast asked me to overwrite or unistall something and i said yes not really understanding what i was doing.

the system didn’t shut down so i shut it down manually since nothing seemed to happen (pushing the button I/O) and then, when i rebooted the pc it goes on a black screen with a white underscore on the top left angle of the screen. i’ve tried to use Ctrl+Alt+F7 to return to graphical desktop or init 5 but seems not working on graphical desktop. on prompt it works fine, but i don’t know how to get back to previous install of drivers or whatever, like a “hey i know i made a disaster, can we go back in time and start again?”

please help me, i’m in total desperation.

Need to knows:

Which desktop?

and we need the output of:

zypper lr -d

Even if you know the following, I am including it for any other readers who are unfamiliar with the methods:

  1. Open a terminal and run that command from the command line;
  2. Use your mouse to select the output, including the command itself
    as you entered it; 1. Use Ctrl-Shft-C to copy the output to the clipboard;
  3. Start your message on the forum, and at the top of the message-editing window, go to the right side of the middle row of formatting icons;
  4. Click on the #
    icon. Your cursor will now be between code tags; and 1. Paste the output there with Ctrl-V.

First, we will look at your repo list, then decide the next step.

Assuming a default install you should have snapper in use that lets you go back. Should be available in the advanced section in the boot menu

details here
https://en.opensuse.org/Portal:Snapper

Also you may be able to boot to a terminal by at the boot screen pressing e then finding the line starting linux or linuxefi going to the full end (it wraps) add a space and a 3 F10 to continue to a terminal log in

You can run yast by typing yast as root

You can run zypper also

Were did you get the package you installed and how was it installed??

Ne sure to apply a bandage to your foot :wink:

Hi guys!!
I didnt know that, but i can’t select the output, i’m in line command, i can’t see the mouse.
I’m pretty sure my desktop is KDE, i installed the first one in the list.
To be more precise, it seems that opesuse attempts to go in desktop mode by Ctrl+Alt+F6 or F7 i don’t remember, or by init5, and a totally black screen appears with the undescore in top left corner, and then it returns to prompt mode (this name is correct?).
i can post the output of the code by an image since i can’t select the output text: (language is italian, si is yes and no is no :))

for snapper if somebody tell me how to use it in prompt mode thanks! i installed synaptics from yast since i thought it was safe, but i was wrong…
maybe i can try to run yast from root and uninstall last packages that ruined everything

thanks everybody

… another way would be to output it to a file.

zypper lr -d > *path*/*filename*

It looks like you have a NVIDIA card you have the repository anyway. In any case the Repos look ok

Did a snapper roll back work??

Log into terminal as root and type init 5

What happens??Show any errors
