Taked Redora Workstation with gnome(sorry of this hurts), 5.Try taked Fedora Standart Workstation install Iso https://getfedora.org/de/workstation/download/ It has works up to reboot and Login as User with a working Desktop.. hast the possible to configuration updating ad setting up the System in all forms. KDE-Programmer Team -have- a Issue.. i guess the problem is, like i have fount out.. to check not correectly the resolution possibility's and filtering out the right Resolutions don't use therewith the right Resolutions , because the TV stay in Black if KDE Started.. or hang .. and stops the system.. and i guess, therewith must be bugfixed the automated setting up Resolutions setup Stack of it.. so, i am fresh here (but longer as since Stuttgart Linuxday at KDE) and i have wrote this issues at the first issues in general/after all, so please help me a bit if i have setting up this issues on the wrong plase ..

a Screen Shot
this is a Photo of Plasma-Desktop on a UHD TV
with a QFHD Resolution with 60 Htz
Gnome works so far.. okey.. add RPMFusion to Fedora32 and have installed nvidia-drivers from.. it has works.. and all was run fine include Nvidia-Drivers, then have i start to install plasma-workspace all so far (exept a couples needed packet's) was installed and add the sddm as starter.... i had the hope to works Plasma on Nvidia better.. and this whant i directly testing.. so let'z gonna try ... stopping the gdm and disable.. and try to start sddm.. ooookeeyy it works so far.... !it works! i have Fire! so, now try it out to let's start the plasmadesk .. and... it has works ! A bit oversized, but has works now... then have i play a bit with nvidia-settings around to make the Size correctly and the Resolution.. Human readable ;) i guess it's a Thing of the displaydriver nouveau <=> Plasma i have see also a error in the Gnome-desktop where i have try to start a KDE-Application with this oversized Screen.. well Gnome-Desktop Works, just not the plasma desktop with nouveau, there should looked on what's there wrong.. Also a kcm tool for handle the resolution and scaling for KDE-Desktop and the GTK2/3 would be really good for the possible to be in able for handle that Scaling with the icons Fonts and so on in both Surfaces. Sounds like a driver issue that you should report to the Nouveau developers. Thanks! well, Gnomedesktop and other Desktop works well.. but KDE/Plasma not with nouveau drivers.. what's there wring ? Because only Plasma works not.. i be to less programmer for know directly what's goes on.. but once do i know.. Plasma have a Problem, other WM's not.. so it's easy to say it's a nouveau problem, no, on other Desktops works it.. best regards Blacky Created attachment 130776 [details]
Nvidia-Settings/Configuration in WinNT
and the Result at the whole is,
you can not install Plasma-releated Distributions on
a UHD Screen, because KDE want make his own thing,
use the wrong resolution and the UHD-TV get a black screen.
i have here the possibility to use a 4096x2160 resolution
with 60Htz and is native
Possible be also => Look Picture, but this is a thing of nouveau Driver..
but the nouveau driver works of the nativ resolution, but Plasma Hardware- recognition , discovery, identification to not works well on hdmi + UHD Resolution, because because the information simply does not exist in kde
hardware recognition.
And therewith it is impossible to install a Linux-Distribution on a Computer with a hdmi - UHD Screen. All exit Linux-Distributions.. with KDE/Plasma

Nvidia-Settings/Configuration in WinNT 2
add subsequently installed kscreen, kde/plasma wont work behind sddm started gnome-desktop open systemsettings5 disable "kscreen 2" service in systemsettings5 logged out from Gnome-desktop and started again the plasma-desktop then have it works again ... and i have access to the DPI contiguration/Adjusting of the Monitor configuration. so be 2 things, once nouveau drivers and kscreen-service best Blacky Created attachment 131034 [details] WebOS TV Open Source, This could give Hardware-Info over HDMI https://github.com/topics/webos-tv https://github.com/danjohnson95/LGTV-node with Java https://github.com/Kvanrooyen/WebOS-Remote over Phython application therewith could normally kscreen read out all technical information over WebOS Webos is Open Source, by start of Kscreen could it test if Web0S connectibal and if yes, read out all technical informations and the possible resolutions. Also could it be possible over Plasma/KDE use Webos-application if a WebOS connected over HDMI if is possible ofver a connectable API for Webos in Plasma this could be great possible for plasma, include a programming remote control in Plasma for Web0S ;) unmaintained |
