Bug Description
I have Avita NS14A2 laptop where i dual boot windows 10 and Ubuntu 20.04. In past few days might be after installing updates I am facing issue where my screen dont display at all when i first boot it and after multiple force shut down and then boot in it work, even on doing Suspend and then opening it, screen didnt not display for about 5-6 minutes, and then shows login screen.
On checking logs software i got these line on those time stamp when display doesnt shows
this is the line:
(Hardware) i915 0000:00:02.0: [drm] *ERROR* failed to enable link training
this line continues for about 30-40 times on average during time when screen doesnt display anything on turing on. So I think there is some issue with it.
As I primarily use Ubuntu 20.04 so didnt check it with windows 10
but on doing cold boot it didnt even shows the boot menu where i can choose between Ubuntu 20.04 and Windows 10.
But once screen starts displaying i dont see that error in logs software anymore and screen doesnt freezes or hangs. It only happen when i either open after suspend or do cold boot.
Please consider this issue on urgent basis, as it takes a lot of time and efforts to make screen display something. :(
And please let me know whether I should do fresh installation of ubuntu 20.04 again.
Sorry for any grammatical mistakes. :)
Thank you,
