On a newly purchased Star Labtop MK III, many desktop environments are not
displaying properly, including gnome and kde plasma. Workaround is to use
xfce4, which is working fully.

startkde blackscreen except mouse cursor. Semi functional as clicking on where the icons should be seems to be working,
though menu images remain shown when they are no longer active.

Adding the kernel option dis_ucode_ldr has no effect
Same with noxorgconf. No effect
The labtop came with ubuntu 18.04.2 LTS where gnome does work.
That's running kernel 4.18.0-21-generic with gnome 3.28
please always use "-v" with the lspcidrake command so we can get the actual pci ids too
Sorry. Here's the card with -v ...

The display does work when using wayland, from run level 3 ...
"startplasmacompositor" from plasma-workspace-wayland works to start plasma,
"XDG_SESSION_TYPE=wayland dbus-run-session gnome-session" works for gnome.
Does the new mesa 19.1.4 and/or kernel 5.2.7 help at all (both currently in testing) ?
No difference. "startx startkde" still gives a black screen with the mouse
cursor. Right clicking brings up the context menu where konsole works. Moving
the mouse around and right clicking leaves many context menus drawn on the
screen, with the most recently drawn being the only one working.
Once konsole is started, programs such as kcalc do work, but with no window
I've tried with nokmsboot, and/or nomodeset. If either or both options are
specified, X fails to start.

This is expected, the Intel ddx is a modeseting driver, so it will fail with those options...
You seem to be booting to runlevel 3 and using startx & co...
Does it work any better if you boot in runlevel 5 ?
And what display manager are you using ?
And another thing is to try the modesetting driver
Specifying kernel option xdriver=modesetting has no effect.
Switching to use run level 5, both gnome and kde work. Tested with both sddm
So it looks like the problem is due to my habit of normally booting to run
level 3 and then using startx.
Want to close this report, or dig further?
The changes in ldetect-lst-0.6.3-1.mga7 do fix the problem. I can boot to run
level 3 and use "startx startkde". Thanks!
Looks like you forgot to close the bug :o)
