Do you have suse-prime installed?

Yes, 0.5 is installed, but it's not used as is, I'm using slightly tweaked version to get rid of bbswitch.

What is output from 'inxi -GxxSa'?

So, openSUSE:Factory still has files for 5.1.16 kernel, so I've been able to download them and install manually. At least I have working system now.

You may still find the old kernel in TW history repo, http://download.opensuse.org/history/ Also I have a collection of old kernels in my repos, e.g. http://download.opensuse.org/repositories/home:/tiwai:/kernel:/5.1/standard/ (In reply to Mykola Krachkovsky from comment #2)

So, I've checked. 5.2.2 is affected too. And despite I've checked 5.1.16 kernel as locked with `zypper al` it was removed. So I have no usable system right now. What the heck? Why it was removed?

Because you still have a kernel-default package on your system even after removing an old one. The multi-version packages are managed in a different way and the number of installed packages is specified in /etc/zypp/zypp.conf. Edit the multiversion.kernels line in that file to allow more instances. In anyway, if the problem persists and 5.1.x is confirmed to work as is, please boot with drm.debug=0x0e option on both working and non-working kernels, and upload the dmesg outputs to Bugzilla, too. -- You are receiving this mail because: You are on the CC list for the bug.

Please attach /var/log/Xorg.0.log after having booted 5.2 kernel and having started Plasma.

I've added attachment, but I don't think this is related to X. Bug presents in TTY when system booted into 3 mode as well. -- You are receiving this mail because: You are on the CC list for the bug.

Also, I've booted with external display and noticed that only notebook internal display is affected, external display works absolutely fine. For example, internal display still shows SDDM, while on external KDE Plasma successfully loaded and works fine.

xrandr info (1st is internal, 2nd external): ``` xrandr -q | grep -A1 ' conn' eDP-1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 344mm x 194mm 1920x1080 60.02 + 60.01* 59.97 59.96 59.93 47.99 -- HDMI-2 connected primary 1920x1080+1920+0 (normal left inverted right x axis y axis) 477mm x 268mm 1920x1080 60.00*+ ```

Also when external display is plugged TTY behaves much better (presence of X doesn't matter).

And it might be false impression, but it seems, when mouse moves from external to internal display it's updated.

Sorry for hijacking this thread, but I experience the same (very similar) problem after updating from 5.1.16 to 5.2.1. I have tried up to 5.2.4 and the problem persists. Hw= Lenovo X1 Skylake GT2 520 graphics rev 07, i915 driver. It is impossible to boot without an attached external screen (via DP). After booting interacting through the external screen, the system behaves normal (but with an unusable internal screen - it is frozen). reverting back to 5.1.6 fixed the issue.

Since it happens with the recent 5.2.x, could you report this to upstream bug tracker? e.g. bugs.freedesktop.org, component DRI/Intel. Feel free to put me (tiwai@suse.de) to Cc there for any assistance. Thanks.

As this bug https://bugs.freedesktop.org/show_bug.cgi?id=111088 exists, there is no point of creating another one, is there any help to create comment there with link to this bug? (In reply to Patrik Jakobsson from comment #23)

Can you try disabling PSR? eg. booting with i915.enable_psr=0

Checked it, seems working fine with 5.2.3. (In reply to Patrik Jakobsson from comment #26)

Found a possible fix at: https://patchwork.freedesktop.org/patch/319173/?series=63774&rev=4

Yeah, I'll try it. -- You are receiving this mail because: You are on the CC list for the bug.
