All;

I bought a new Lenovo X1 Carbon 3rd generation, installed Fedora 21
and neither the mini display port or the HDMI port work per an
external display.

Installed Fedora 22 as well but it has the same issue.

Can someone help me debug this?


Thanks in advance


What video card?

If nVidia, it is most likely and Optimus issue.





Intel HD Graphics 5500

Also, it turns out the HDMI port works even with the latest kernel.

Screen is still a bit washed out but not bad if I run "xgamma gamma .8" in /etc/X11/xinit/xinitrc.d/75-set-xgamma.sh
