Just a wild guess; substitute your grub config part blacklist=nouveau nomodeset nouveau.modeset=0 with module_blacklist=nouveau,amdgpu,radeon i915.alpha_support=1 Install the new grub config and rebuild your init ramdisk, just for consistency ... -- Leon
> module_blacklist=nouveau,amdgpu,radeon i915.alpha_support=1ok I did that - regen that file and verified with cat /proc/cmdline This is not a dual monitor situation. I also removed all that other "legacy" stuff I had in there. no difference. Jerry

If you are only using an intel GPU, you don't need them. -- Jonathan Billings <billings at negate.org>
Ok so I re-installed CentOS 8 from scratch. and compared the two. C7 and C8 X log files. As 7 loaded Intel drivers and 8 does not. grep LoadModule Xorg.0.log on CentOS 7 [ 22.856] (II) LoadModule: "glx" [ 22.863] (II) LoadModule: "intel" [ 22.878] (II) LoadModule: "dri3" [ 22.878] (II) LoadModule: "dri2" [ 22.878] (II) LoadModule: "present" [ 23.054] (II) LoadModule: "evdev" Clearly loading the intel driver... Good. grep LoadModule Xorg.0.log on CentOS 8 [ 12.792] (II) LoadModule: "glx" [ 12.804] (II) LoadModule: "modesetting" [ 12.812] (II) LoadModule: "fbdev" [ 12.813] (II) LoadModule: "vesa" [ 12.835] (II) LoadModule: "fbdevhw" [ 12.839] (II) LoadModule: "glamoregl" [ 13.120] (II) LoadModule: "fb" [ 13.726] (II) LoadModule: "libinput" Not loading the intel driver - bad What should I look at to find out why ?
