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 ... Card:Intel 810 and later: Intel Corporation|UHD Graphics 620 [DISPLAY_VGA] (vendor:8086 device:5917) (rev: 07) 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 decorations. I've tried with nokmsboot, and/or nomodeset. If either or both options are specified, X fails to start. (In reply to Dave Hodgins from comment #8) > > 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 and gdm. 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) Resolution:
