This issue seems similar to the thermal problem the latest MacBook Pro had. IIRC Apple fixed it in a BIOS update. I don't know if/when Dell will fix it (or if they even can fix it).

After installing Centos 7 on this machine - and the MATE desktop - I have the following issues:

- When the machine boots and asks for the password to decrypt the password, the text is minuscule, really minuscule... Can this be changed somewhere?

- When it continues booting, the Centos boot animation is displayed in roughly the top-left 1/8 of the screen. Can this be changed somewhere so it uses the entire screen as is customary?

- I see no option to hibernate the machine, only to suspend. Did I have to do anything special to make hibernation possible when installing Centos 7? The machine has 16 Gb of memory and the swap space was automatically set to 8 Gb.

- The 4K desktop is unusable because the font, icons etc. are too small. Since I have not yet figured out how to increase font size etc. when in 4K mode, I changed display resolution to 1600 x 1200. This is only a stop-gap measure though and I hope there is a better solution.

- The trackpad is obnoxious to use and it is very hard to use it to maneuver around the screen. Should I disable it and simply rely on the mouse?

- I do like the fact that the touchscreen can actually be used to select windows in Centos, move them around etc.

- When I have the Dell extension dock connected at startup, the OS crashes and gives me a stack dump. Disconnecting it and rebooting solves the problem but it really should not be like this...

- Connecting the Dell extension dock after booting the computer results in some kind of crash every so often but the OS stays up.

- Even with the dock not connected I have found the OS suddenly crashes and two seconds later you are back at a desktop with absolutely no running apps no matter what you had running. I also get crash messages from xorg.

Clearly the current release of Centos 7 is not ready for prime-time on this laptop but I have yet to try a later kernel, 4.x, to see if that makes any difference.

Anyone else have had similar experiences?
