HDMI still disconnected after switching ot Nvidia

[Pinkolik]

Describe the bug Hello! I have a device with Intel Graphics and Nvidia, it has multiple video outputs (HDMI, mini-display) which are connected to GPU, which means they're not accessible when running in integrated graphics mode. But even when I switch to Nvidia xrandr still says that HDMI is disconnected.

Any advice?

Same is happening to me, I switch to NVIDIA drivers and My external display is connected via a dock and It is not detecting at all. My display is using HDMI and the xrandr is not detecting anything.

@rafay99-epic @Pinkolik , is this still happening on a more recent version of optimus-manager-git ? My Asus TUF has the same problem where HDMI and mini DP ports are hardwired to the nvidia GPU, but I'm not facing those problems anymore

Since this issue isn't active for the last year and a lot has changed in many aspects of multiple software, we'll keep this case opened for some days and close it if no further comments are provided.

Have a nice week ahead.

@nwildner Thanks, brother. I switched to optimus-manager-git on Awesome Window Manager. I'm not sure what I did, but it's currently working.

However, there's still one more issue. When I switch from integrated to hybrid mode using Optimus Manager, everything works fine. But when I shut down the machine and reboot, the laptop display does not show anything. I can access the tty session, but Awesome Window Manager does not show up. All my other extensions are working, but my window manager does not display graphics. I have no idea what's going on. Is it my window manager, the graphics card drivers, or Optimus Manager?

Any ideas?

Sup @rafay99-epic .

So, in your case, you get no video on AwesomeWM when setting to hybrid mode? What login manager are you using?

For me, it is the contrary: If I set to integrated mode, I'll not be able to have output on those ports. It needs to be at least hybrid and nvidia will consume a minimum amount of energy because it is hardwired to those ports...

@nwildner

Currently, I am using the SDDM login manager, and thanks for the feedback, I solved the problem. It had nothing to do with the drivers or Awesome Window Manager. It was the config file.

I was importing polkit, and that command was not running properly when Awesome Window Manager was loading after the login.

Hello, @nwildner. Last time I tried connecting HDMI to laptop was this January. It was working, however, after some time the video would freeze and I had to restart. I don't know if it's still an issue now, I'll try to check in the following days

[nwildner]

Sup @Pinkolik . Ok, lets wait for your input on this one.

Nvidia also released a lot of updates on their side as well, and driver 550 was pretty fu***d up. I've got random stalls with the classic caps lock blinking behavior of a Kernel crash. I've reported that in this article

https://www.gamingonlinux.com/2024/06/you-may-want-to-avoid-nvidia-driver-550-if-youre-on-a-laptop/

nvidia-dkms version 555 seems to be fine so far.

[rafay99-epic]

Yeah, switching to just Nvidia cards is not stable. Last night, I switched to using only Nvidia drivers, and the animation and UI were quite laggy. But the moment I switched to hybrid mode, everything worked fine and perfectly.

There are still a lot of bugs, and improvements are required.

[nwildner]

Sup @rafay99-epic . Thanks for your report here.

Lets wait for @Pinkolik confirmation on the HDMI disconnection stuff.

Meanwhile, are you able to report all your findings related to "choppy" performance on nvidia mode on the following case?

• 498

That will be the case where we will concentrate all reports related to nvidia mode being sluggish :)

[rafay99-epic]

@nwildner Your welcome, brother.

I will be taking a look at this issue.

[Pinkolik]

@nwildner Looks like everything works flawlessly now. No interruptions or freezings. Thank you for your time 💪

[nwildner]

As for the HDMI issue here, I'll then close the case. For the black screen and nvidia tearing/sluggish issues, please refer to the respective cases opened.

Thanks for the feedback and for taking time to report this back after this optimus-manager hiatus.

Have a nice day.
