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.

Upgraded the CPU and now have GPU problems... any help? (self.linux)

I went from a 2600x to a 5600 (yes, MoBo is compatible after BIOS update) and now for some reasons I get 1FPS in games and monitor is not really detected (resolution is fine, but I can't change refresh rate and in "color" settings it's shown as "None-1 Monitor").

I tried:

monitor factory reset;
updating GPU drivers (was already running latest);
removing and purging GPU drivers (sudo apt remove ~nnvidia and sudo apt-get purge nvidia*) and reinstalling (sudo apt install pop-desktop system76-driver-nvidia);
resetting RAM speed to factory (2400Mhz).

Still nothing.

As you can guess from the commands, I'm running PoP!_OS and a nVidia GPU.

What else can I try?

Thanks in advance!

Issue found: I disabled secure boot from BIOS and now I can change resolution and refresh rate. Since I updated BIOS just before installing the new CPU it went under the radar

Boot from a USB stick with a Live environment on it. See if you get the same issue.
