HDMI not working on clean install

KilroyMcK commented 5 years ago

I decided to install ubuntu 19.04 on my y530 and after following the provided tutorial the hdmi worked. Then I installed Kubuntu, whicht didn't work at all. Then I installed Ubuntu again and now the HDMI doesn't work.

I tried the steps provided in the troubleshooting section and in other issue-threads, no luck. both monitor and cable still work properly.

-Ubuntu 19.04 -Kernel version 5.0.0-25-generic

Interesting. What is the output of prime-select query?

dush1729 commented 5 years ago

Goto Software and Updates.
Select additional drivers.
Install the proprietary nvidia driver and restart.

This fixes the issues. But creates another issue. You cannot change brightness now. Please help if you find a fix for this.

I have the same issue with 18.04. Can't get HDMI or DP to work. Any ideas?

sith@legion:~$ prime-select query nvidia

sith@legion:~$ uname -a Linux legion 5.0.0-29-generic #31~18.04.1-Ubuntu SMP Thu Sep 12 18:29:21 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

kfechter commented 5 years ago

@610th Are you running 18.04.3 or 18.04.1? the 31~18.04.1-Ubuntu suggests that its not the newest 18.04, which has a bunch of fixes but that could just be a different version number from somewhere.

Also, is your machine the Y530 or one of the newer models?

610th commented 5 years ago

Ah, sorry for leaving that part out. I'm running 18.04.3 (Kubuntu).

I'm running a (~1 year old?) Y530-15ICH.

kfechter commented 5 years ago

Interesting.

Debugging these issues is a bit hard. I'm currently running Ubuntu with gnome, and everything seems to work.

EDIT: wayland is experimental, so that's not important

610th commented 5 years ago

I agree. I've been debugging this kind of stuff too many times. :-) Hoped for an easy solution. Pew.. And I'm not running Wayland.

@610th try upgrading the bios - https://pcsupport.lenovo.com/in/en/products/laptops-and-netbooks/legion-series/legion-y530-15ich/downloads/ds503758

I faced the same issue issue in Lenovo Legion Y540 but fixed it by changing graphic driver to proprietary

610th commented 5 years ago

@dush1729 I did that just before installing Kubuntu. I think this might be related to secure boot.

From dmesg:

EDIT: Disabling secure boot fixed my problem.

kfechter commented 5 years ago

Ah, yeah SecureBoot screws things up even though it should work fine on Ubuntu 18.04 and up

dush1729 commented 5 years ago

Yes secure boot disabled and fast startup in windows disabled are a must for dual boot. Glad you found the fix. I hope I will fix my brightness issue someday. :( My screen always remain on 100% brightness in Ubuntu.

dush1729 commented 5 years ago

Hi, I've finally got a fix for my brightness issue. Just follow what's written here - https://askubuntu.com/a/199652/1012471

Works for my Lenovo Legion Y540
