Installed Kali Linux on my Alienware M17 laptop;
- laptop monitor was working
- connected to an external monitor via HDMI, configured the external monitor as the primary, laptop monitor as secondary; all were working initially
- used xrandr command to dim laptop monitor; laptop monitor stopped working, while external monitor was working
- If I unplug the external monitor and reboot my laptop, the laptop monitor will display as expected; as soon as connect the external monitor back in HDMI, external monitor will work but the laptop monitor will black out with occasional flickers.
Does anyone have a solution?
