--- Comment #10 from George R. Goffe <[email protected]> --- David, I have reinstalled several older versions of Fedora Core (27, 29, 31) in a virtual environment (VirtualBox). FC27 and FC29 seem to be working well... even with the startx and .xinitrc changes. I have been working on the Fedora Core 31 virtual machine by applying package installations "dnf install '*xorg*' and other "normal" upgrades but still no joy (WITH NOMODESET installed). I have removed the "nomodeset" kernel command-line parameter and am seeing a more or less "normal" response to the startx & .xinitrc setup. All these Fedora Core systems worked with "SDDM". As I understand it, "nomodeset" turns off the kernel level hardware support for the video card. Here's what one site says "https://askubuntu.com/questions/716957/what-do-the-nomodeset-quiet-and-splash-kernel-parameters-mean": The newest kernels have moved the video mode setting into the kernel. So all the programming of the hardware specific clock rates and registers on the video card happen in the kernel rather than in the X driver when the X server starts.. This makes it possible to have high resolution nice looking splash (boot) screens and flicker free transitions from boot splash to login screen. Unfortunately, on some cards this doesn't work properly and you end up with a black screen. Adding the nomodeset parameter instructs the kernel to not load video drivers and use BIOS modes instead until X is loaded. Have you seen anything in the KDE code that might depend on the setting of "nomodeset"? Regards, George... -- You are receiving this mail because: You are watching all bug changes.
