Random xorg & kernel errors, keep logging me out of TDE, and power management wonky

Greetings, First, THANK YOU SO MUCH FOR TDE! The horrible things they have done to KDE from 4.x onward seem unspeakably bad. I am so very grateful you revived this much more productive interface. I am however having some trouble and not sure how much is TDE, video driver, touchpad/touchscreen driver, kernel, and/or other hardware driver issues. If it isn't TDE itself, I appreciate help isolating which components to tackle first. I haven't figured out the causality yet, and it is random seeming but frequent. Periodically the little crash indicator red light icon shows up in the lower right corner of taskbar. Sometimes the message when I mouse hover over the icon: "A problem in the xorg-x11-server-Xorg-1.20.1-5.1.el7 package has been detected". Other times it is something about a kernel error, and then before I can read more, I get logged out of TDE and brought to the login screen. Also the screen will dim down considerably some times, seemingly randomly, appearing to be around 10-25% brightnness, but command line cranking it up to 1.0 barely raises it up. I have to fully reboot the system to get the screen brightness back to normal. It _might_ (and I emphasize guessing heavily) coincide with multitouch on the touchpad, but really can't trigger it reliably. It usually happens faster if I am using the laptop, but sometimes I come back and it has logged itself out without my being there at all. Sometimes it seems to trigger the logout when I am using 2-finger or 3-finger scrolling on the touchpad. Sometimes the touchpad makes the mouse jump around. Other times it behaves just fine. There is also a weird behavior if I accidentally click two fingers on the touchpad 3-4 Konsole screens appear, and I click on the X in upper right hand corner of each window to close, when I click on the 2nd to last one, 3 more appear! The only way to stop that is to type "exit" in each rather than using the mouse. Weird behaviors, but seem interconnected somewhat? Everything else seems to be working well though I haven't tried any 3d tests yet. The "Automatic But Reporting Tool" shows "My (0)" and "System (4) but in the right hand column shows "No problems detected!". I'm not sure where to begin as far as logs that might be useful, so could use a little guidance. There is a lot of whitenoise (to me at least) on the logs, so suggestions would be appreciated. This is a very new 2 in 1 laptop, and I wonder if it has anything to do with the drivers between the touch screen (which I only rarely use) and the touchpad (use a lot), and/or something with the video drivers. But I'm totally shotgunning here.

Thanks kindly!
