Hi everyone,

new at the forum and also to linux gaming, Im trying to go from windows to linux gaming, but something that i cannot get my head around and thats is how you get resize bar to work on linux.

What i got working was, install the with UEFI on with out secure boot and then enable secure boot in bios afterwards?
Ps. running nvidia.

Create a file /etc/modprobe.d/nvidia-rebar.conf

Contents:

# /etc/modprobe.d/nvidia-rebar.conf

options nvidia NVreg_EnableResizableBar=1

okay, but still with secureboot enable in BIOS or can you do that just in UEFI mode?

It doesn’t matter.

I don’t know. You can check if it’s actually using BAR

I know that with nvidia driver you can check it with this command:
nvidia-smi -q | grep -i bar -A 3
Then it tells you how big your first bar is:
BAR1 Memory Usage
Total : 32768 MiB
Used : 27 MiB
Free : 32741 MiB

Hi,

just to let you know i can confirm that rebar is working without secureboot :slight_smile:
Thanks for the help

PS. On my Asus motherboard you cannot enable CSM and Rebar, so you need to disable CSM and have secure boot to other os witch mean disabled.
