Hi,
I am experiencing this issue approx. the third time (over some months), but don't remember how I got rid of it before:
after d-u, KDM login screen takes my user/password, then seems to advance to KDE desktop but stops after some seconds and falls back to KDM login screen.
This is what /var/log/kdm.log says:
Code:
X.Org X Server 1.11.3.901 (1.11.4 RC 1)

Server terminated successfully (0). Closing log file.
However, I do get to the LXDE desktop by entering the following on tty1 (even if this is a root desktop, which cannot access all of my user configuration settings):
Code:
# /etc/init.d/kdm stop
# startx
If anyone understands the problem, I would be grateful for being explained what's wrong and how to get it working again.
Please let me know if more diagnosis information is needed!
Thanks,
Thomas |

are there some disks/partitions running full?
@hubi that can not be a driver problem otherwise startx would not work... |

Thanks, x-un-i! - That was the reason! My root partition (20 GB) is 100% used.
Searching for the reason why 20 GB can be so easily consumed, I found that ls /var/cache/apt/archives/ shows multiple different versions for each program.
Do you know how to tell it that it should remove any versions older than the last two+ |

"apt-get autoclean" removes all old packages, but keeps the current ones. "apt-get clean" removes all packages from this cache. |

Sorry, guys, to get back again: freeing disk space was not enough to get it running again...
Following your tips, I did this:
Code:
# apt-get autoclean
# df -h /
size: 20 G / used: 13,5 G / free: 6,5 G
# reboot
This still didn't resolve the issue: KDM still wasn't able to start KDE, but instead after 1 second returned to the login screen.
Fiddling around, I chose Fluxbox from KDM menu (I thought this is a less complex WM / desktop, so it might work without dbus, which I thought was causing the issue, according to kdm.log (see initial post)...).
=> Really, fluxbox came up correctly.
I decided to go through the installed wm's to get a clue on what's wrong.
Next choice in my list was KDE/Plasma workspace... and ... astonishing enough, now KDE started correctly!
Can you explain this behaviour / what should I have done after disk cleanup to enable KDM to start correctly? |
