On 26 Mar 2019 I reported here that I could not install Fed 30 beta-1.7 on a Dell Precision 5530 (end 2018 model) with i5-8300H & UHD graphics 630. Immediately after first few lines of startup messages the screen went black and except for some very faint 'pulsing' of backlight nothing further happened. Could not get any info as 'Ctrl-Alt-Fn' not working. Had to use power button press to quit. The same thing with the latest Fed Rawhide (kernel 5.1.x). The laptop came with Ubuntu 18.04 installed which I removed to install Fed 29. Fed 29 worked perfectly with all the 4.20.x kernels but when the kernel updated to 5.03 (same as on Fed30) a comparable phenomenon as with install of Fed30 beta apparently happened: upon reboot the screen went black before gdm screen appeared and stayed that way. Now having the 4.20.16 kernel available I could restart and get a journal log of previous boot so I reported a bug for the kernel on bugzilla (1693365) attaching journal log. I deleted everything kernel 5.0.3 and excluded further kernel updates in dnf.conf so I can still use the Precision 5530. However this is unsatisfactory state of affairs so I searched if others had experienced the same problem. Indeed there were a few reports of Arch, Manjaro and OpenSuse Tumbleweed users experiencing apparently the same thing. Common factor: Intel 8th gen CPU & UHD 620/630 & kernel >= 5.0.0. The UHD 620/630 have as graphic output options: eDP/DP/HDMI/DVI (eDP = 'embedded Display Port' for use internally in portables). In https://bugs.freedesktop.org/show_bug.cgi?id=109959 some people claim to have found a bug relating to eDP and laptop panel version. A patch was posted that seems to resolve the issue for some. If this occurs on more laptops I think this is, until resolved, a blocker bug for Fed 30 final (and beta). Should I post a bug report for Fed 30 beta.
