Title: plasma desktop crashes
Post by: dsat on 2018/09/09, 14:54:57
Hi,

since a while I have the problem that my plasma desktop crashes on start-up. If I remember it good it is related to the upgrade of xserver-xorg-core 1.19 to 1.20. I installed LXQT, so I have a desktop but I prefer KDE-Plasma.

After sddm login the desktop shows up twice, but not complete and interrupted by a black screen and then remains black only showing mouse cursor, no start menue, no control panel. I can start all programms with Alt+F2 and use them as usual.

That's what I tried so far:
- I created a second user but the problem persists
- I uninstalled and reinstall all plasma related packages but no success

System is a pure debian sid fully dist-upgraded, hardware is a Lenovo X230T:

Two other sid installs, one in virtualbox and the other on hardware with nvidia graphics, do not have this issue.

Any idea how to solve this is appreciated.

Next test could be is to test the xorg-intel driver.

Hi,
I removed xserver-xorg-video-intel and it makes no difference. Isn't that strange?

Not removing, you should try it,  because you are using the modset driver, so test it.
Why, because nvidea works fine and also the vm.
It also could be some kind of software which is causing that error.
Trial and error.

How do I disable modesetting and activate i915 graphics?

I tried nomodeset as boot option but then I end up on a console with no graphics at all.

Do I need a xorg.conf with intel driver? xserver-xorg-video-intel is installed again.

the pure nomodeset is a ubuntu thing - one will need to specify it - read more in the kernel documentation

Hi,
I followed your link and have i915 graphics now:
Code: [Select]
inxi -G
Graphics:  Device-1: Intel 3rd Gen Core processor Graphics driver: i915 v: kernel
           Display: x11 server: X.Org 1.20.1 driver: intel resolution: 1366x768~60Hz
           OpenGL: renderer: Mesa DRI Intel Ivybridge Mobile v: 4.2 Mesa 18.1.7

But the behaviour did not change: black desktop with mouse cursor, no control panel, no start menu. What am I missing?

New user also doesn't work but lxqt is working?
Then you can move back to the modeset-driver by renaming the xorg.conf to xorg.conf~ and restarting the xserver, if you want so.
You can check the xorg.0.log , take a look too the journal ...

but i think
1. some kind of library is missing? (did you reinstalled plasma with the recommends? like apt install --install-recommends, how old is your installation, is it siduction or is it a pure debian?)
or
2. a special software is installed, which causing plasma to crash.

what is the difference between the nvidea driven pc and the x230?
check the installed software, plasma*, libkf5*, and so on, what is installed what is not ....

give us an "inxi -r"

Hi,

I'm back on modesetting. System is pure debian sid and 2 or 3 years old. All packages are installed without recommends but I now changed configuration to install with recommends.

I have no access to the other two installs, because I'm not at home right now.

Code: [Select]
inxi -r
Repos:     Active apt repos in: /etc/apt/sources.list.d/debian.list
           1: deb http://ftp.de.debian.org/debian/ unstable main contrib non-free
           Active apt repos in: /etc/apt/sources.list.d/virtualbox.list
           1: deb http://download.virtualbox.org/virtualbox/debian/ stretch contrib non-free

I hope virtualbox from Oracle is not too special.

I'll try to reinstall with recommends.
