Re: [WORKAROUND] SDDM/Breeze Issue With qt5-* Package Upgrade

I just bit the bullet and updated.

Had the same issue - after entering my login credentials, I was thrown back to tty1. After downgrading sddm-kcm to 5.5.2-1 my system worked again.

Then I've installed the new version again and removed (actually just renamed it) SDDM's cache and now things are working.

Thanks arojas!

Deleting the cache(s) did not work for me even though I tried multiple times to delete, restart sddm and login. I also tried to downgrade sddm-kcm, which didn't help either, only when I also downgraded qt5-base it worked again.

Re: [WORKAROUND] SDDM/Breeze Issue With qt5-* Package Upgrade

It would be very weird if sddm-kcm had any effect on this issue. It parses and edits config files, in no way is it directly linked with sddm and will certainly not write any config changes arbitrarily without the user's explicit invocation. (And I'm fairly certain there were no breaking changes in it from the 5.5.2 and 5.5.3 version bump)

Yep, I updated it again and it still works with the old qt5-base.

Using the default theme solves it for me too!

Re: [WORKAROUND] SDDM/Breeze Issue With qt5-* Package Upgrade

@Cuke: Confirm, I have no problem with `maui` theme.

Everybody: please remove *both* /var/lib/sddm/.cache and ~/.cache and see if it improves things.

Unfortunately it didn't help.

I encountered this problem on desktop and notebook, both with intel graphics.

it works fine on desktop with nvidia-340xx.

Hm, on my up-to-date system sddm with breeze theme works.
EDIT: with xf86-video-ati

Re: [WORKAROUND] SDDM/Breeze Issue With qt5-* Package Upgrade

Works here as well with nvidia, likely an intel graphics speciality... I wonder if the driver cached some broken shaders or similar with the breakage from the QT update and now since this was reverted tries to use them and keels over? Weird that

Yes, changing away from breeze theme to something else fixed the problem for me. For the record, I have Intel GMA 4500MHD.

I can now confirm that deleting the cache only worked once for me. I now changed the theme to maui and login works again.

Re: [WORKAROUND] SDDM/Breeze Issue With qt5-* Package Upgrade

I also have good results switching to maui theme.

That bug is filed against kcm_sddm, which doesn't seem like the correct place - it's probably either sddm or the breeze theme, right?

Also, I found that sddm works fine if run directly from a root console, whereas it fails when run through systemd. Whenever the sddm service is running, running startx from another user console returns this error (http://www.x.org/wiki/FAQErrorMessages/#index6h2), but running "startx -- :1" as suggested on that page works. So to me it seems like something in the breeze theme is causing some part of sddm to use X improperly.

OK, changed theme to Maui and re-updated. I logged in fine. I will mark the thread solved.

This is not a solution, it's a workaround. We still don't know why the Breeze theme is broken

Re: [WORKAROUND] SDDM/Breeze Issue With qt5-* Package Upgrade

According to the bug report (https://bugs.kde.org/show_bug.cgi?id=358171) the recent update (plasma-framework 5.18.0-2) fixed it for some people. Not for me though, just like Jonathan Doman in the bug report, I could never login with the breeze theme.

Re: [WORKAROUND] SDDM/Breeze Issue With qt5-* Package Upgrade

BTW - do you use maybe nvidia cards with nouveau? I wanted to check something, so i installed nouveau instead of nvidia drivers and after reboot...screen was flickering, SDDM could not launch and in console i had massive amounts of sig crash.

Re: [WORKAROUND] SDDM/Breeze Issue With qt5-* Package Upgrade

I have an Optimus setup, so I boot with the Intel card. I usually boot and run only the nVdia card, but there is a bug in the xorg drivers preventing me from doing that at the present.

Changing the theme didn't help? I am reluctant to think it is the same issue if changing the theme didn't help.

You're right, chaging the theme to Maui helped. However Brise theme was working with lts kernel...
I'm using intel driver
