Plasma5 - SDDM black screen after kernel/mesa/xorg update
On my machine running slackware-current and Eric's Plasma5 set of packages, I've upgraded all together kernel-4.4.5, mesa-11.1.2 and xorg-server-1.18.2, and sddm login stopped working.
Booting in runlevel 4 I get only a black screen with blinking cursor on the top-left side of the monitor. Everithing works flawlessy booting in runlevel 3 and using "startx". Nothing has changed with the latest "KDE 5_16.03" upgrade. In /var/log/messages I find lot of Code:
kernel: [ 158.167700] traps: sddm-greeter[1367] trap invalid opcode ip:7ffb34613646 sp:7fffac74c8a0 error:0 Code:

Initializing... P.S.: I've a skylake processor. |
I did a full upgrade yesterday it went flawless. and I run multi lib.
I skipped two upgrades and did this one. after downloading the latest stable current 5. First I upgraded all my slackware and made sure all my sbo-builds would be updated with any new additions. then this is the script I used. after I uninstalled nvidia. Code:
#!/bin/bash created an intrid.gz. then I ran my linux setup scripts. then rebooted with the generic kernel then rebuilt the latest nvidia. after logging in the theme manager would not change. so I logged out. init 3 logged in as root and deleted ~/home/.kde and .config and .cache of my user. then logged using init 4 signed in as the user and things where ok. The only issue I find is fonts are going blurry they do not seem to refresh at times. after that I rebuilt all my media ffmpeg vlc patents yes rebuilt pulseaudio so it would use my jackd2 then rebuilt mplayer to use patents yes. rebuilt my alsa-plugins so they would build against ffmpeg and jack2 and pulse audio rebuilt speex from slackbuilds. That is my experience. I only blacklist I have alien and compat32. |
Ok, I solved the issue, for reasons that I don't know, "sddm" no longer wasn't in "video" group.
Adding sddm user to the video group did the trick. Michelino |
