Sometimes KDM is not ran after boot instead black screen

Hello,

I can't really reproduce it but sometimes kdm fails to start, after grub boot black screen appears and no matter how long I wait nothing happens. Then when I press ctrl+alt+f1 shell login appears and from there I can start kde. I've tried reading the logs many times but I can't figure out what is wrong, maybe I'm reading the wrong logs?

Here are the log files after fail start:
.xsession-errors - http://pastie.org/private/8ac1tblmbxgapavxndxa
.Xorg.0.log http://pastie.org/private/guspozou7hgbza63qwe7bw
kdm.log http://pastie.org/private/z3oybm2gnh6d4p3tm8n7q
list of installed packages and their version http://pastie.org/private/18qu9tw8pbsn4edwywqhq

Thanks

Re: Sometimes KDM is not ran after boot instead black screen

Hi there!

I am having the exact same problem. I'm using a Thinkpad T440.
I mostly get a black screen instead of a normal boot. But the correct keyboard-layout is not loaded. After switchting with Ctrl + Alt + F1 I have to

loadkeys-de

It also seems that the kdm service is already running because i can't start it. However if i do

systemctl restart kdm

the normal login appears and everything seems fine.

It's frustrating and I can't figure out, what causes the bug.
Hope someone knows a solution.

edit: some typos.

Hello,

I have fixwd the problem, it was something with the video drivers (i dont remember exactly what was it), check if you have installed them properly.

Re: Sometimes KDM is not ran after boot instead black screen

Hi,
Thanks for the hint. My drivers seemed to be installed properly.

I also checked the settings and realized that the "early activation of KMS" was not activated (as described here).
I enabled this and since then I had no Problems.

Maybe your reinstallation of the drivers did the same job. Would be interesting to know whether there are different causes for the same bug.

Please mark the thread as solved.
