issues with nvidia-driver: how to erase all of them

have issues with the nvidia-driver

the opensuse 13.2 only runs in command line after booting.

have found some instructions - for ubuntu

dpkg -l | grep -i nvidia

except the package nvidia-common all other packages should be purged.
If you want to be sure that you will purge everything related to nvidia you can give this command

sudo apt-get remove --purge nvidia-*

the asterisk in the end means (Purge everything that begins with the name nvidia-)

that does not work for me…

well in yast i found the following

asusfan - Fan Control for Nvidia Based ASUS Graphics Cards - Version 0,1 - 203.1.2
libdrm_nouveau2 - Userspace Interface for Kernel DRM Services for Nvidio Chips - Version 2.4.46 - 3.2.2
libXNVCtrl - Nvidia Control Library Version 340.76 - 1-28
nvdock Tray icon for launching NVIDIA Settings - Version 1.02. 10.1.3
nvidia-texture-toos - version 2.0.6.-23.1.3
vdpau-video VDPAU DRI Driver Interface to NVidia - Version 0.7.4.-2.2
xf86 - vidieo-nv - NViDIA Videotreiber für den Xorg - X - Server Version 2.1.20 - 7.1.2
Xorg - x 11 driver-video - nouveoau - Beschleunigter Open Source Treiber für nVideo-Karten Version: 1.0.9. - 3.1.2

should i erase all of them

best method would be via commandline - any idea!?

No.
And you apparently don’t have the nvidia driver installed at all (unless you installed it “the hard way” via the .run installer from nvidia).

The only thing that you definitely should uninstall is vdpau-video, this only works with the nvidia driver and will break (hardware accelerated) video playback if nvidia is not installed.
You can also remove libXNVCtrl, nvdock, and nvidia-texture-tools, they don’t make much sense without nvidia either (but shouldn’t cause a problem).

Keep your hands off the rest! :wink:

dear wolfi many thanks for the quick reply. Will ty to do all you explained.

hope that i can go ahead - (this is a very very nasty issue) - and perhaps i can collect some more information that is useful to give you more insights into the issues.

Which commands can help here. What should i do to find out more bout the troubles i am faced

any commands - any ideas that i should do (perform)

Well, you should probably explain what kind of issue you have in the first place…

If it’s related to the graphics driver, posting your /var/log/Xorg.0.log is probably a good idea. At least it should tell what graphics driver you actually use now…
As mentioned, your package list doesn’t indicate the nvidia driver being installed. Maybe just installing it would fix your problems already?

hello dear Wolfi,

thanks -

the issues as it appears:

starting the system and booting will end up in command line.

i have not the option to end up in KDE

i guess that there was an ugly update from opensuse 13.1 to 13.2

More on all that later the day. i will respond more later

So Xorg fails to start. The log file should indeed tell what’s wrong in that case.

A guess: you have an /etc/X11/xorg.conf that tells Xorg to load the nvidia driver, but you uninstalled the driver?
Remove the xorg.conf, and the graphical system should start using the nouveau driver.
Or, (re)installing the nvidia driver should help as well if that’s the case.

thx for the reply.

How To Use Journalctl how can i export Journalctl to USB !?

Reading the system log. journalctl is our interface into the machine’s journal/l

**question: **i need to save / store the content of the journalctl

how to do that!?

btw - have made some screenshots - i will publish them later the day…

Run:

journalctl

how can i export Journalctl to USB !?

journalctl > logfile.txt

There are options to restrict the output, please have a look at the man page (“man journalctl”), or the command help (“journalctl --help”), as always.

But actually you should rather take a look/post /var/log/Xorg.0.log as I wrote.

Unless you are using GDM, in which case the Xorg log is redirected to systemd’s journal and some other file which I’m not sure at the moment where it is located. /var/log/gdm/ maybe?

hello

many many thanks for the reply. you are very supportive. AND i will performe all the things - asap

[as i am not in front of the machine - i only can offer some screenshots i did last evening ]

see some insgights into the general logs - more to come later.

i will publish more later the day. Stay tuned.1

Well, I see a lot of “No space on device” messages there.
A full root partition can of course cause all sorts of problems, including (but not only) Xorg not being able to start.

Make room on your /, maybe delete some snapshots if using btrfs.

hello dear Wolfi,

many thanks for all . - thanks for the hints:

Following seems to work for me:

  1. rm -rf /var/log/*
  2. dmesg -c
  3. reboot Since this works,

also a good idea - the following:

sudo /etc/cron.daily/logrotate

now the system is okay again.
