Thanks, Felix and Patrick. The Xorg logs are in ~/.local/share/xorg, not /var/log (or its subdirectories). It is also available in the journal with a type of "/usr/lib/gdm/gdm-x-session" when using X11. When using Wayland, it's is not in the journal. And things get more confusing... I switched back to Wayland from X11 to generate a Xorg.0.log to help debug why the intel DDX was not selected, and Wayland came up with the intel DDX selected: > inxi -Gxx Graphics: Device-1: Intel UHD Graphics 620 vendor: CLEVO/KAPOK driver: i915 v: kernel bus ID: 00:02.0 chip ID: 8086:3ea0 Device-2: Chicony Chicony USB2.0 Camera type: USB driver: uvcvideo bus ID: 1-7:3 chip ID: 04f2:b649 Display: wayland server: X.Org 1.20.8 compositor: gnome-shell driver: intel unloaded: fbdev,modesetting,vesa resolution: 1920x1080~60Hz s-dpi: 96 OpenGL: renderer: Mesa DRI Intel UHD Graphics 620 (WHL GT2) v: 4.6 Mesa 20.1.4 compat-v: 3.0 direct render: Yes (In case it's not clear, I "switch" between X11 and Wayland by selecting one or the other in GDM when I log in.) My guess is that the log is no longer of use, since it shows a successful selection of intel, but the Xorg.0.log is in https://paste.opensuse.org/60046995, if it does have value. Since i'm now up on Wayland with the intel DDX, I'll stay there to see what happens. I'll then try X11 with the intel DDX if that seems warranted. Is this occupying too much bandwidth on the list? I can move this to bugzilla, if so. It's probably two or three issues: 1) the screen flickering, 2) non-selection of the intel DDX, and maybe 3) documentation of where the logs are kept. Let me know your preference. Thanks for all the time you're spending on this. David On 7/31/20 2:06 PM, Felix Miata wrote:

In some environments, maybe only some distros, it's ~/.local/share/xorg/Xorg.0.log which is sometimes copied to /var/log/Xorg.0.log. Historically, and in every openSUSE environment I've used, it's always been /var/log/Xorg.0.log. Note too that in some situations X will run in an additional session, such as using startx from a vtty while a display manager is running. In those situations the 0 will be replaced by a 1, or if a third session, a 2. Previous sessions' logs are saved by the same name except with .old appended.
With Wayland sessions, I have no idea if there automatically exists any such log as a discrete file, but IIRC, in Fedora at least, equivalent information shows up in the journal if the session is Gnome, and maybe for other DEs/WMs too.
