[SOLVED] Can not launch KDE after pacman -Syu

Recolic Keghart · 2017-04-26 07:27:36

sddm can not launch KDE after system upgrade. I tried to reinstall plasma, kwin, xorg_xinit, but it didn't work.
I failed to find out the exact reason from my log files, so logs are all attached below.

Could you give me some hints? Or should I move this post to kde forum?

Thanks a lot!

--------------------

How does the problem appeared:

sudo pacman -Syu
reboot
(Now everything looks ok. )
shutdown
(Go sleeping...)
boot Arch Linux, problems appears now...

Snapshot:
A snapshot (taken by mobile phone)

Log files:
journalctl log
/var/log/pacman.log
/var/log/Xorg.0.log
/var/log/Xorg.1.log

-----------------------------------------------Edit:
Occasionally, I found that if I close the laptop lid while launching KDE (it locks and suspends) then unlock, KDE will be started immediately and perfectly.
The truth is that KDE will take about 3 to 5 minutes to start and I thought it crashed... In several trials the phenomenon is consistent.
The error window is caused by kcmserver:

Apr 26 19:36:32 RECOLICPC ksmserver[657]: ksmserver: autostart service "/home/recolic/.config/autostart/dropbox.desktop" failed to launch (dropbox has been already removed)
Apr 26 19:36:32 RECOLICPC ksmserver[657]: ksmserver: Starting autostart service  "/home/recolic/.config/autostart/guake.desktop"
Apr 26 19:36:32 RECOLICPC ksmserver[657]: ksmserver: Starting autostart service  "/home/recolic/.config/autostart/ibus-daemon.desktop" (ibus has been already removed)
Apr 26 19:36:32 RECOLICPC ksmserver[657]: QXcbConnection: XCB error: 3 (BadWindow), sequence: 634, resource id: 31457294, major code: 40 (TranslateCoords), minor code: 0

The problem is that KDE is taking too long to launch... I got the log.

Use a decent pastebin client: I can't open those links in my browser, and I have no intention of downloading them...

I set their HTTP header to text/plain just now... Maybe they're ok now...

So this is a hybrid graphics setup? There have been a couple of threads about this post the upgrade.

Yes. I've been using nouveau for a long time, but I know little about it...

There are several posts mentioning this can be caused by sddm cached files.

Boot into multi-user target (see systemd wiki page) ,
and remove /var/lib/sddm/.cache

also check if /var has enough free space available (df -h ), if not you can use paccache to remove parts of pacman pkg cache.

I did it and, by the way, removed these invalid autostart tasks mentioned above. Everything goes well. Thanks a lot for help.
