Mageia forum

Hi!

Recently, I got a reconditioned Dell Latitude E6510 laptop. Installed Mageia 7.1 without issue, changed the display manager to SDDM from GDM, as I just find it easier to work with, and I primarily use Plasma as my desktop. I performed the full system update including the recent qt5 update. Upon boot, the SDDM screen is blank, so resetting the DM to GDM allows me to log into the system. Any attempt to start Plasma leads to a dialog stating that kwin has become unstable and asks to switch to openbox, which also doesn't open.

Any help to troubleshoot this and possibly file a useful bug report will be greatly appreciated.

Hi there, this might be the same issue as in viewtopic.php?f=7&t=13190
Can you try whether downgrading the packages listed there allows SDDM to work normally again ?

Downgraded all listed packages including symlinks, sddm and plasma still don't run. Sddm shows a mouse pointer and nothing else.

Turned logging on: saw the following:
sddm-greeter[3734]: Cannot mix incompatible Qt library (version 0x50c02) with this library (version 0x50c06)

Well as it says, your sddm version doesn't match with the installed version of the Qt libraries.
So best upgrade everything again, then do a fresh boot, and when sddm has started, wait a minute or so until nothing happens anymore and switch to another tty via e.g. Ctrl+Alt+F2 and post the output as root of

Code: Select all

systemctl status sddm -al -n150
journalctl -ab|grep -i sddm

So....
with updates-testing (core, nonfree and tainted) enabled (but not set for updates), I ran urmpi --auto-updates. It pulled in a couple qt libraries from updates-testing, and it looks like I have a functioning plasma desktop, so there's likely something there that should have been pushed but wasn't.

Thanks for the help, Dok!
