ksmserver segfault [SOLVED]
ksmserver segfault [SOLVED]
I just upgraded my main computer form stretch to buster, which resulted in inability to logon to my desktop (KDE), because of the abve mentioned segfault in ksmserver.
I am looking into two solutions, both depend on being able to log into terminal without going through desktop.
1.
Insist with dist-upgrade until bug is solved.
2.
Load an alternative desktop (xfce), from terminal
So, basically I need help on launching a terminal if desktop is unusable.
Thank you,

Basically, put 'exec xterm' into your ~/.xinitrc and run startx.So, basically I need help on launching a terminal if desktop is unusable.
However, somehow I think this is not what you are looking for.

Re: ksmserver segfault
There should be options in the login screen, where you can select which DE or WM you want, this does depend what display manager you are using, with lightgdm it is up in the upper right corner, a little wrench like thing.
You can also disable or not use a display manager ,
I believe for KDE, the display manager is KDM, and looking at one image,(older) there is a cog wheel, clearly labelled, it says "session type", that would be where you could select
a different DE, the other image, newer, is much different, and no text, to identify the options, just a arrow pointing down, a power "button", and another arrow thing, horrible the way modern DE,and display managers do things, but sorry , that is another topic, if you move your mouse around and play the "clicky dicky,click the icon" game, one of them should give you a menu where you can select Xfce, if it is installed.
Below might give some idea, :

You can also disable or not use a display manager ,
If you do disable the display manager, you can still use 'startx', and start XFCE4 or a WM ,whatever,...What segfault says, is correct, but the same I am not sure if that is what you are looking for,from: https://unix.stackexchange.com/question ... -using-gui Fake display manager
There's a way to specifically avoid starting a display manager on Debian. The scripts that start display managers at boot time check if they are the default display manager, to ensure that only one display manager will be run. So set a fictitious default display manager. Make sure that /etc/X11/default-display-manager exists but doesn't contain the name of a display manager (e.g. make it empty).
The ctrl+alt+f1 (2,3,4,etc) is ok , if all you want is a terminal, but you probably will not be able to run 'startx' and start another DE or WM from another tty.So, basically I need help on launching a terminal if desktop is unusable

Yes, thank you, I had forgotten that key combination.Dai_trying wrote:Can you Ctrl+Alt+F1 (or other F keys) to get another tty open?
Re: ksmserver segfault
There is no responsive button in KDE after the segfault.
Will try all tomorrow, too late now.

Re: ksmserver segfault
SOL completely.
I did manage to launch alternative terminal and shutdown sddm and the failed instance of KDE desktop.
Dist-upgrade did not fix anything, reported everything up to date, just some packages to be removed by autoremove.
So I decided to fire up smxi and install xfce.
Rebooting system only showed black screen, startx did not launch.
During install I was offered the choice to use sddm or lightdm, chose sddm, but would like to revert to lightdm, I know there is a file that can be edited to do that, but I forgot where it is.
Please help.

Re: ksmserver segfault
Yup, that is what it says in the link I posted earlier as well :
https://www.makeuseof.com/tag/choose-sw ... -managers/
https://www.makeuseof.com/tag/choose-sw ... -managers/
.For Debian:
The procedure is similar to Ubuntu: replace the path to your old display manager to the new one in /etc/X11/default-display-manager. You have to edit the file as root. Alternatively, runand choose the new display manager.Code: Select all
sudo dpkg-reconfigure yourdisplaymanager
Re: ksmserver segfault
I think you are lost, this happens sometimes after large upgrade. Better reinstall system, I don't think you can fix it, since all desktop environments don't work.
Re: ksmserver segfault
I am thinking of reinstalling system, will wait till Saturday for official release of buster, right now it is RC3.
Will try to fix in the meantime.
Thank you.

https://www.debian.org/releases/buster/
Debian 10.0 was released July 6th, 2019.
Re: ksmserver segfault
Do you mean that buster is the new stable now?
I thought that release was next Saturday, not realizing that July 6th. is also a Saturday.

Re: ksmserver segfault
On another note, i wiped clean the system partition, formatted to ext4, set bootable flag, mount point to / all from install CD.
The problem is I cannot install nvidia driver because it conflicts with nouveau.
Tried but apt could not find package nouveau.
New question: how to remove package nouveau?

Re: ksmserver segfault
As I recall the nouveau driver gets blacklisted when nvidia-driver gets installed so no need to remove it.
Re: ksmserver segfault
Here is what I did to fix: since I had to get some work done and got tired of fiddling around with an unusable computer. I decided to reinstall system.
This is not much of a problem for me because:
/home is a separate partition from system so many of my settings are already there, and,
All my data is stored on a different physical drive.
So I fired up a buster CD in another computer and reinstalled, it worked.
