From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Need Help with Video Drivers on a Mid2012 Macbook Pro (sh.itjust.works)

Hello, I have been trying to get my drivers to play more nice with my hardware. When I originally installed Arch, it automatically installed the nouveau driver which mostly worked. However I was having issues with some windows rendering with big white boxes and a couple random crashes of the OS.

After looking into fixes I was recommended to swap to nvidia drivers, and I followed a guide to install the AUR nvidia-470xx-utils. But this completely broke my drivers. Luckily I was able to use TTY to revert these changes and got the nouveau drivers reinstalled.

With that background out of the way, I'm now dealing with some new issues. After logging in it now takes much longer to load the desktop and my whole system will randomly reboot. I'm hoping someone can point me in the right direction.

I am happy to post any more info or clarify points, I'm still very new to a lot of this.

Here is my gpu readout when I run lspci -v:

01:00.0 VGA compatible controller: NVIDIA Corporation GK107M [GeForce GT 650M Mac Edition] (rev a1) (prog-if 00 [VGA controller]) Subsystem: Apple Inc. Device 00fc Flags: fast devsel, IRQ 16 Memory at c0000000 (32-bit, non-prefetchable) [size=16M] Memory at 90000000 (64-bit, prefetchable) [size=256M] Memory at a0000000 (64-bit, prefetchable) [size=32M] I/O ports at 2000 [size=128] Expansion ROM at c1000000 [disabled] [size=512K] Capabilities: Kernel modules: nouveau, nvidia_drm, nvidia

EDIT: It is done, thanks to everyone here for the help! No more hairdryer temps!

I was under the impression the nvidia drivers would help my system run a bit more efficiently. So if this provides the same result then I’m happy. Thank you, I’ll try this out later today!

you got two graphics chips in there - Intel HD4000 and Nvidia GT650M. the system is supposed to switch amongst them based on load, but that doesn't always work as expected and the Nvidia chip is always powered on, using battery, emitting heat, etc.

by entering this variable, you turn off the Nvidia chip entirely and the system runs off the reliable and super-supported Intel HD4000, which is hella plenty for the majority of use cases.

I got one of these and running on the Intel graphics it performs like it was built for linux; with Nvidia, total shitshow.

also make sure to implement the wake/sleep scripts to turn off/on CPU cores if it takes a long time to wake from sleep.

Before I do something stupid, am I safe to boot to this MacOS usb drive? It was flashed via dd using the High Sierra ISO from archive.org.

I don’t want overwrite my installation which I’m pretty sure it would prompt me to install beforehand. Just want to do a quick sanity check first.

yeah, you're safe. either boot to the installer, open terminal, enter command, reboot, or, hold down command-s before clicking on the usb icon. that will boot into single user mode, which is way faster.
