OS : leap 42.3
kernel : 4.4.103-36-default
Graphic driver : Nvidia
Install mode : The hard way (opensuse naming).
I run into problem when installing the recent nvidia driver. Then Following a suggestion from nvidia In try to return to nouveau and then re-install nvidia
I have manually reverse the configuration
1: remove nomodeset in command line kernel boot
2: remove /etc/modprobe.d/xxxxxx file that looks like disable nouveau.conf
3: remove line in 50-blacklist.conf that disable nouveau
4: reinstall drm-kmp-default
5: NO_KMS_IN_INITRD --> nothing to do because does not exists
6: do mkinitrd
7: reboot
8: black screen when login screen is supposed to come
Starting x from init 3, show an error, message
Plasma is unable to start as it could not correctly use OpenGL 2. Please check that your graphic drivers are set up correctly.
Other error :
Can't open display:
XIO fatal IO error 13 (permission denied) on X server :0 from kinit
Could not start ksmserver
could not connect to d-bus server
So How could I do something that is like reinstalling nouveau.
I encountered the same error during a 42.2=>42.3 upgrade (with DVD) with nvidia drivers installed from the nvidia repo. Fortunately I was on my test machine as I was not able to repair the problem from a rescue session; I was forced to do a clean install which I cannot do on my main workstation.
Do I follow the OP’s above procedure before I begin the upgrade, starting with uninstalling from the repo? Will that automatically bring back nouveau?
Also, I am currently using grub legacy; “nomodeset” is not in my kernel boot command; what should I do about that?
Thanks very much! Sorry, left out this question . . . according to 42.3 Release Notes, after removing the nvidia drivers (from the wording this seemed to apply either way, from the script or from the repo), then “drm-kmp-default” needs to be reinstalled. Yes?
Again, TIA.

EDIT: Btw, despite my sig, I am upgrading from 42.2. I haven’t been here for a good while, so apparently I can’t edit my sig.
Well, you don’t need to install it per se.
It contains backported graphics drivers from Kernel 4.9 though, so probably good to have (especially if your graphics card/chip is quite new). Unless it gives you problems (which may be the case for older intel chips e.g.)…
It might even get pulled in automatically, I think, if you install updates.
ase it’s better to uninstall it.

If you are logged in, you should be able to edit your sig in the “User Control Center” (top right of the page). There should be a link “Edit Signature” on the left side below “Settings”->“My Profile”.
I’m obliged. For safety sake, I’ll reinstall it after I’ve removed the nvidia drivers and cleaned up modprobe.d if necessary; apparently there is no xorg.conf any longer so no problem there.
Found the route to changing profile elements, so the sig is done, too.
Unless you modified things manually, there shouldn’t be anything to clean up in modprobe.d though…

xorg.conf is not there by default (nor needed) anymore since about 10 years.
But you could have created one manually, e.g. by running nvidia-xconfig (which some people apparently still believe is necessary, it isn’t).
It is still used if it exists, and if the specified driver is not found, X will fail to start.
PS, Just to be sure: do not delete /etc/X11/xorg.conf.d/ or the files provided by the distribution in there!
This will break things.
Thanks! I didn’t know about the xorg.conf.d directory. I looked at the files there and found no reference to the graphics card or driver. Do I need to do something with that directory?
Correct. The driver is determined automatically by default.
You can of course specify a driver explicitly (either in xorg.conf or in some file in xorg.conf.d), but it should not be necessary. (and it will break X if the driver cannot be loaded for some reason, e.g. if you change graphics cards)
