After I log in, the mouse is shown on the grey wallpaper, and nothing more. If I attempt to switch to a text tty: mouse is gone, same wallpaper, and no more control on mouse or keyboard, this looks like a video/Xorg issue. Xorg.log shows that it loads the Intel module but still looks for the nouveau one: [ 6.565] (II) LoadModule: "nouveau" [ 6.565] (WW) Warning, couldn't open module nouveau [ 6.565] (II) UnloadModule: "nouveau" [ 6.565] (II) Unloading nouveau [ 6.565] (EE) Failed to load module "nouveau" (module does not exist, 0) Second attempt: blacklisted nouveau kernel module -> nouveau still shows in `lsmod` after reboot (w/ a non-ml kernel), wft? But Xorg.log doesn't mention nouveau anymore, success? No, it still hangs w/ ml kernel. ==== After all this, I wanted to get back to kernel 3.10, to see now that nouveau is off, if that changes something. Well this is a surprise, everything works fine w/ this 3.10.0-514.26.2.el7.x86_64 kernel (suspend/hibernate/wifi/hmdi-out/dell keys/vmware) BUT the bluetooth (and the dell fn+radioswitch key). I re-installed drv-nouveau, removed the blacklist file from /etc/modprobe.d and all is still OK, but Xorg doesn't loads nouveau driver despite the fact that lsmod shows the nouveau kernel module (I checked, during my former attempts w/ this 3.10 kernels, it was already the case: Xorg not loading drv nouveau). IOW this whole topics turns into something more complex (call that a mess?) ;-) and I don't understand how it could not work w/ regard to these laptop features and how it works now. I'm willing to help w/ the experimental or ML 4.x series kernels, but in terms of personal productivity, I will also focus on solving the bluetooth issue w/ 3.10 kernel.
