KDE / Plasma have a Problem with Higher Resolutions like 4K or 8K
over nvida-card (here at me a GTX 660 TI at an HDMI to a LG UK6400PLF)an UHD TV
it can easy not start and not stay stable.
i have Test it at Openmandriva 4.x and Fedora 32,
STEPS TO REPRODUCE
==========================
1st. try
1. create a bootmedium with OpenMandriva or Fedora KDE-Spin
2. boot therewith
3. and the Plasma will crash..
---------------------------------------
2nd. Try
1. create a bootmedium with openmandriva 4.0
2. system is started, go to console with control+alt+F2
3. install in the squash fs task-lxqt,'echo "exec startlxqt" > .xinitrc'
4. startx
5. Xorg started, can open calamares and install the system..
---------------------------------------
3st. try
1. OpenMandriva installed, but hangs at sddm
2. go to tty2 kill sddm, create a .xinitrd file with exec startlxqt,
it has start and i be in able to work into..
3. edit .xinitrc again add startplasma and start X again..
4. KDE/Plasma hangs again...
---------------------------------------
4. Try
Create a Bootmedium with Fedora32 KDE/Plasma-Spin
Boot therewith up to the Plasma-Logo... then nothing happens anymore..
the best resolution in WinNT is 2560x1440, this should be as Standard
resolution if the TV/Display supports more as 4K.
In WinNT works it very well and if i install the Nvidia Drivers works also the
sound of the TV over HDMI.
OBSERVED RESULT
It's flawless a Bug in Plasma.
EXPECTED RESULT
Plasma should work on 4K or also at 8K
We are at 2020 (so in the Future ;))
i want install my loved KDE ;)
Kernel, coreutils and tools works still fine..
but Plasma with an Higher resolution not..
(or is it due to HDMI? Can not be, other WM works..)
SOFTWARE/OS VERSIONS
Windows: WinXP, Win7/Win10 works
macOS: -
Linux/KDE Plasma: all versions of Plasma works not
(available in About System)
KDE Plasma Version: ..i guess all version
ADDITIONAL INFORMATION
nothing..
