OR no. Just saw the version of the driver. My mistake. You’ll have to follow this guide for that driver.
That guide is for 340xx, I’m using 430xx.
Otherwise, it’s pretty much how I installed 430xx in the first place (like I said, I used the info in the sticky about nvidia drivers on top of the forum, if you scroll to the bottom there is a peace where it says “Other 4YYxx drivers (example for linux54)”).
However, it doesn’t show up in mhwd nor the settings GUI this way, which is what’s confusing me. Does it mean I can no longer rely on mhwd and the GUI, and need to look at inxi in order to see my currently running driver, or is something else going on? I hope anyone can confirm.
Quick side note, I think mhwd -i video-nvidia just installs the newest theoretically compatible nvidia proprietary driver. However, theoretically 455 should be compatible to my card so it wants to install that, but practically anything above 430xx results in the system freezing at TCP startup/shutdown
