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

    Hello there

    This is a new installation on the laptop model mentioned above with KDE and Full Wayland.

    The laptop screen and its definition is very nice, however when I add a second screen I cannot say the same (see below).

    Please note I use a Dell docking station that gets the HDMI and connects to the laptop on one of the the USB-C ports.


    IIyama 27 inch screen (ProLite B2791HSU model)

    I cannot get the same clear definition than on the laptop screen and also the way some items are display do not look right.

    The setting I have are: 1920 x 1080 (which is its native resolution) and setting the DPI to 72.

    Sometimes clicking on some icons are not fully shown or just the definition that the laptop screen has is a much better quality. Also some times some parts of the screen look darker than others.


    Dell 24 inch screen

    I also tried on a 7 year old 24 inch screen and with this one I managed to have a better look and feel than with the 27 inch however it is still not good enough and found by testing the same above problems.


    Questions

    1. The laptop has a graphics card as follows
      nVidia TU117GLM [Quadro T1000 Mobile]
      Intel UHD Graphics
    2. Is there anything I am missing to set up or perhaps drivers I should try?
    3. Is there anyone else with a similar configuration and issues?



    Any help will be appreciated Thank you!

    I don't have dual screens, so I don't know much about your problem. However, may I suggest you try KDE/Plasma with X11 (i.e. without Wayland).

    I've been quite happy with Leap 15.2 since I installed it some time ago. However, when I last logged in (Monday), I decided to give Wayland a try. And, quite honestly, it is not ready for prime time. When I next login (probably after updating), I'll be going back to X11.
    openSUSE Leap 15.2; KDE Plasma 5.18.5;

    72 DPI is an extremely low resolution for a computer screen less than 30 years old. The lower the resolution, the lower the quality. Most PC apps and environments assume a minimum DPI of 96, and many modern screens, particularly laptops, are capable of much more. Modern desktops dissuade or outright deny applying an accurate DPI WRT the physical DPI of a display screen. Matching the logical DPI to the physical DPI takes a heroic effort that is worth it only for a limited set of needs. Web browsers enforce a minimum DPI of 96 within their display ports. DPI is more often used as a scaling device, notably in Gnome. A 27" 1920x1080 screen is most often used optimally at the assumed DPI of 96, even though it's physical DPI is about 82.

    Please check that inxi is installed and install if it isn't already, then do from Alt-F2 or Konsole:
    Code:
    inxi -Gxx | susepaste -n estebanc00
    susepaste -n estebanc00 /var/log/Xorg.0.log
    You may get an error message about upload failure, but the results should be found at https://paste.opensuse.org/lists . If you get an error message about Xorg.0.log not found, then do this:

    Too new hardware. Try to use newer kernel from Kernel:stable repo: https://download.opensuse.org/reposi...able/standard/

    Docking station and Full Wayland brings additional headaches.
    And you not mentioned Thunderbolt 3.

    Hello there

    thanks for your answer. Yes I did not mention Thunderbolt 3.

    Is this the correct article to switch the kernel https://doc.opensuse.org/documentati...ltikernel.html ? or do I have to follow different steps and use 5.8 as you pointed out on the link above?

    Both i7-10750H and T1000 are only a few months old. I wouldn't expect full support from 15.2, and possibly not even from TW - yet. To find out about TW you could boot the latest live TW media to test your hardware's support. If satisfactory, you could first try a 5.8 kernel in 15.2, and if that isn't enough, upgrade 15.2's X11 to the latest version from the build service repos.

    Even with older ("fully supported") hardware, a laptop with both Intel and NVidia GPUs (monikered aka Optimus) takes some effort to configure. You'll almost certainly need Suse Prime installed to achieve success. The wildly different display densities of a laptop screen and a 27" FHD screen present their own problems even without the complication of Optimus.

    PS, still waiting to see Xorg.0.log.

    Thanks for your answer and yes you are right both are quite new. The Xorg.0.log failed to upload yesterday, sorry about that. Now it is on https://paste.opensuse.org/64137819


    I am going to try the steps as you suggested.
    1) TW latest (check kernel) and test how it goes

    2) 15.2 with newer kernel (same as TW)

    3) If needed upgrade X11 on 15.2 to the latest.


    Questions

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

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

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


    Thank you very much for all your help!

    Thank you, I will start testing with TW.

    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.
