SDDM black screen - no cursor. Minor Plasma 5 issues

[OBenY]

Hi!

I've decided to migrate my desktop to Plasma Frameworks 5. Everything seems to work almost flawlessly.
Two problems were discovered so far.

1. After starting SDDM i've got blank screen without cursor. I can't do anything.
It doesn't matter whether sddm was started from root account text-console or started by /etc/init.d/xdm (appropriate entry in /etc/conf.d/xdm is present).
Starting Plasma 5 from lightdm or directly from command line by issuing startkde works fine.

/etc/sddm.conf generated by:

Code: Select all

sddm --example-config > /etc/sddm.conf

Plasma was merged by "emerge plasma-workspace" instead of installing whole set plasma-frameworks-XXX. Additional packages emerged by hand.
sddm-kcm is installed and configuration options are visible in Plasma5 System Settings.

SDDM merged with options:

Code: Select all

[ebuild   R    ] x11-misc/sddm-0.11.0::gentoo  USE="consolekit upower -systemd" 0 KiB

sddm user is added to video group.
pam_ck_connector.so nox11 commented out from /etc/pam.d/system-login according to ebuild advice.

No error messages visible on console when sddm is started, no entries visible in /var/log/messages.

I have no idea what is wrong or how to debug this problem. Have you got any ideas what should I check?

2. It is not possible to start konsole from menu entry.
Following notification appears:

Code: Select all

KDEInit couldn't start '/usr/bin/konsole'

When I try to start konsole from xterm following error is visible:

Code: Select all

FAILURE (KCmdLineArgs):
Application requests for isSet("display") but the "display" option
has never been specified via addCmdLineOptions( ... )

However when i try to start it with passing graphic system (both: raster and opengl) - it works:

Code: Select all

konsole --graphicssystem opengl

Have you got the same issue?

Hi OBenY.

You disable manualy KDM? With systemd is needly run:

Code: Select all

systemd disable kdm
systemd enable sddm

The error "KDEInit couldn't start ... " is very common in the actual KF5.

[OBenY]

KDM is not installed, I've removed everything what is related with KDE4.

Only packages that still remains on my system and are required by kdelibs-4 are:

Code: Select all

[ebuild   R    ] kde-base/kde-env-4.14.3:4/4.14::gentoo  USE="(-aqua)" 0 KiB
[ebuild   R    ] kde-base/kdebase-pam-9::gentoo  0 KiB
[ebuild   R    ] kde-base/oxygen-icons-4.14.3:4/4.14::gentoo  USE="(-aqua) -sources" 0 KiB
[ebuild   R    ] kde-base/kdelibs-4.14.6-r1:4/4.14::kde  USE="bzip2 udev udisks -acl -alsa (-altivec) (-aqua) -crypt -debug -doc -fam -handbook -jpeg2k -kerberos -lzma -nepomuk -nls -openexr -opengl -policykit -spell -ssl {-test} -upower -zeroconf" CPU_FLAGS_X86="mmx sse sse2 -3dnow" 0 KiB

[ebuild   R    ] kde-base/kioclient-4.14.3:4/4.14::gentoo  USE="(-aqua) -debug" 0 KiB

I'm not using systemd, I hate it...
I really don't won't to use systemd...

OpenRC for the win

Did you get this sorted.

Was it because you had Plasma(wayland) selected as your session type on the sddm login screen at all?

I had this similar problem and changing the session to Plasma from Plasma(wayland) solved the problem.

Hi!

I've decided to migrate my desktop to Plasma Frameworks 5. Everything seems to work almost flawlessly.
Two problems were discovered so far.

1. After starting SDDM i've got blank screen without cursor. I can't do anything.
It doesn't matter whether sddm was started from root account text-console or started by /etc/init.d/xdm (appropriate entry in /etc/conf.d/xdm is present).
Starting Plasma 5 from lightdm or directly from command line by issuing startkde works fine.

/etc/sddm.conf generated by:

Code: Select all

sddm --example-config > /etc/sddm.conf

Plasma was merged by "emerge plasma-workspace" instead of installing whole set plasma-frameworks-XXX. Additional packages emerged by hand.
sddm-kcm is installed and configuration options are visible in Plasma5 System Settings.

SDDM merged with options:

Code: Select all

[ebuild   R    ] x11-misc/sddm-0.11.0::gentoo  USE="consolekit upower -systemd" 0 KiB

sddm user is added to video group.
pam_ck_connector.so nox11 commented out from /etc/pam.d/system-login according to ebuild advice.

No error messages visible on console when sddm is started, no entries visible in /var/log/messages.

I have no idea what is wrong or how to debug this problem. Have you got any ideas what should I check?

...

Have you got the same issue?

System info:
~amd64, all synced, up-to-date, latest kde-overlay
desktop machine, two monitors connected to GeForce 760 GTX, latest nvidia-drivers installed

...

Thanks!

Yes and I've opened a super hazy bug against the (apparent cause) of the issue...

It appears the qt5 toolkit isn't able to see the Nvidia GLX acceleration or something along these lines... It's a bit above my ability levels to sort out. It does appear that a lot of Gentoo + KDE4 + Nvidia (??) graphics cards appear to be having similar issues during the migration to Plasma 5...

• If I built the qt5 toolkit with the USE flags -gles2 -egl I get the same SDDM (black screen) issues as you have described. As we know SDDM requires OpenGL 2.0+ support - so it's probably not able to access the Nvidia drivers for some reason...
• If I built the qt5 toolkit with the USE flags +gles2 +egl I get the SDDM Login screen rendered correctly. However KWin 5 is then using EGL rendering. Even replacing the media-lib/mesa EGL & GLESv2 library files with links to the proprietary Nvidia ones doesn't allow me to launch a full Plasma 5 session. I can launch a LXQt session on top of KWin 5 - compositing works better when using the Nvidia libraries (it's really glitchy with the Mesa ones).

I'm going to do some more testing of SDDM with the former -gles2 -egl USE flag options (rebuilding world just now)... The black screen makes it harder to debug!!

It's getting a bit tiresome - I've been banging my head against this issue for more than a couple of weeks now...
