Hey! I wrote the latest ISO to my USB drive and booted into it. Everything seemed fine.
I have two monitors; my main is 144hz, with a 60hz on the side.
I set my main monitor to 144hz, both screens blacked out for a second, and then came back with 144hz correctly applied to my main monitor.
I went through the installation up until the partitioning step where I realized I had some stuff left to do inside Windows, so I cancelled and went back inside Windows to sort those out.
Booted back into the Live USB, set my main monitor to 144hz, however this time only that monitor blacked out. When it came back, it was rapidly flickering as if it was rendering every second hertz or something. Trying to set it back to 60hz also took forever. Setting it to 120hz works, but it felt really odd scrolling these forums on it, as if it would ever so slightly lag behind intermittently.
What’s going on?
I have an Nvidia 970 for reference and booted into the second option for nvidia cards, however on second boot it didn’t even let me pick any option. I’m wary of installing EndeavourOS until I can figure out if this is suddenly a permanent thing.
You might try manually selecting the live ISO as your boot option, with a boot override option if you have one available. As far as I’m aware, that menu allowing you to select “Nvidia” should always appear, if you’re booting from the live ISO.
I don’t foresee any issues with running the Nvidia GTX 970 at 144Hz using the proprietary Nvidia drivers. I’ve used the Nvidia GTX 970 successfully under EndeavourOS on my loungeroom gaming rig, and I’m able to push the refresh rate up to 144Hz on my workstation’s Nvidia A4000.
I did have the live ISO as the first boot option, and I also tried doing a straight boot override. For some reason it simply won’t show that menu again, which I’m assuming from your response might be the reason I’m getting these flickers. I suppose I can try rewriting the live ISO to my USB drive.
If getting that boot option is proving to be difficult, you might be able to proceed in any case. I suspect without being able to select that boot option, it’s defaulting to the open-source nouveau driver, and perhaps that’s not co-operating with the high refresh rate.
You’d be able to confirm this by running this within the live ISO environment:
inxi -G
This is what the proprietary driver would look like:
I antipate the open source driver would instead specify nouveau there.
If that’s all it is, you could still install EndeavourOS at the lower refresh rate, then after installation, and from within your new OS, install the proprietary Nvidia driver using the nvidia-inst tool.
Ah, perhaps some more context, and maybe an alternative fix.
According to the Arch Wiki on Variable refresh rate, the open source Nvidia Nouveau driver does not support FreeSync or G-SYNC. If your monitor has this enabled, try disabling it while using the Nouveau driver.
I do not have a VRR monitor, so I will try checking if it’s indeed defaulting to nouveau for some reason. If it is, I’ll just go ahead with the installation like you’re recommending.
