Trying to troubleshoot a no video signal issue. Running Ubuntu mate 18.04 LTS on a dual boot Ubuntu-Windows machine. (Asus X399 Extreme mobo) When trying to boot this evening was getting no video signal. I have dual Titan Volta GPU's and tried switching the HDMI cable to the 2nd GPU. No difference. Also tried clearing CMOS. Has been working fine for a year or so. Never experienced this before.
Not getting any error messages on the motherboard on boot. I know my monitor is fine because I can plug my laptop into the 2nd HDMI input. Both GPUs are getting power as I see the fan spinning.
Is it possible either a recent software and or driver update has hijacked the video out signal?
Is there some keyboard combination I can try on boot? Any feedback welcome!
