Hi,
I recently purchased Thinkpad P1 Gen2(Intel® Core™ i7-9850H CPU @ 2.60GHz ×
12 with Mesa Intel® UHD Graphics 630 (CFL GT2))
I have latest Ubuntu 20.04 installed. (5.4.0-40-generic #44-Ubuntu SMP Tue
Jun 23 00:01:04 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux)
I am seeing issues with an external monitor is connected to HDMI port while
booting. The monitor is not detected. If I connect the monitor 'after'
boot, it is detected, but same issues happens (blank screen) if the
machine is suspends and tries to come back up.
I have attached dmesg output with lspcon errors.
Thanks,
Unmesh
