Fresh Leap 15.2 on Dell Precision 5550 - Problems with 27 inch Second screen through HDMI

[estebanc00]

These error messages are indicative of newer Intel and NVidia hardware than the 15.2 software supports:

[    19.143] (EE) Unknown chipset: NV167
[    19.837] (EE) modeset(G0): glamor initialization failed
[    19.949] (EE) modeset(0): [DRI2] No driver mapping found for PCI device 0x8086 / 0x9bc4
[    19.949] (EE) modeset(0): Failed to initialize the DRI2 extension.

Thank you, I will start testing with TW.

A) To upgrade the kernel on 15.2 shall I use this article?
https://doc.opensuse.org/documentati...ikernel-latest

Looks appropriate for the devel kernel, which is likely overkill. Probably better to apply that process but use Kernel:/stable instead.

b) Is it worth once the kernel is upgraded to test other drivers for the NVIDIA card such as the NVIDIA drivers ?

I have no idea whether you'll find a proprietary NVidia driver matching Kernel:/HEAD or Kernel:/stable. I suspect not. Newer FOSS drivers would come from enabling X11:/XOrg/openSUSE_Leap_15.2 and using the same procedure to install as for Kernel:/HEAD.

c) Shall I consider checking and perhaps upgrading KDE (plasma or wayland) to a newer version ?

Negative re KDE/Plasma. Given nrickert's comment about Wayland, I wouldn't expect material help from enabling and upgrading to X11:/Wayland either, but if you're ambitious.... I've yet to attempt to use Wayland, and don't see it happening in the foreseeable future either.

Note the links I have here provided can be downloaded and copied to /etc/X11/zypp/repos.d/ as a simpler alternative to the zypper ar process commonly described for adding a repo, which creates a new file in that location, subject to typing and consequent errors.
