My apologies for the noise.

At least you don't care for the correct driver. The Radeon driver is pre-installed and used for your Radeon graphics. The nouveau driver can't handle your AMD (the graphics brand formerly known as ATI) at all, since it's a driver for NVIDIA graphics. A workaround probably could be to migrate from "turn monitor off after 15 minute" to "never" do so. However, in my experiences with Ubuntu flavours that suffer from this screen blanking issue, the screen comes back, if you push Ctrl + Alt + F1 (or F2, F3 ... F6) and right after that Ctrl + Alt + F7. "nouveau (/nuːˈvoʊ/) is a free and open-source graphics device driver for Nvidia video cards" [1] "Radeon (/ˈreɪdiɒn/) is a brand of computer products, including graphics processing units [...] by Radeon Technologies Group, a division of Advanced Micro Devices (AMD)." [2] "This guide shows you how to use the open source Radeon driver for some ATI/AMD graphics cards and APUs, which is part of the xserver-xorg-video-ati package. This driver provides 2D and 3D acceleration in your video hardware. For the most recent releases of Ubuntu (and its flavours) this driver is usually as fast as the closed-source, proprietary fglrx driver (called AMD Catalyst) from AMD Inc. Furthermore the Radeon driver supports some older chipsets that fglrx does not. The Radeon driver is already pre-installed in Ubuntu."

Power problem with Radeon 7750 card and Nouveau driver
Hi Everyone, I'm working on Ubuntu 20.04, x86_64, fully patched. It has the 5.4.0-64 kernel. The machine is a Dell XPS 8930 with an i7-8700, https://www.amazon.com/gp/product/B078N85NCR. I'm having a power management problem. The monitor goes to sleep and does not wake up. Power Management applet settings are (a) turn monitor off after 15 minutes, and (b) never go to sleep. Moving the mouse and tapping on the keyboard does not seem to wake the monitor. In this state I can SSH into the machine. I think this issue has to do with Noveau. The problem started after I removed the original GeForce GTX 1060 (Nvidia driver) and installed a Radeon 7750 (Nouveau driver). I switched cards for the open source driver. The Radeon 7750 card is https://www.amazon.com/gp/product/B00C7EPSVS. The monitor cable is HDMI to Mini DisplayPort. It is a new cable for use with the Radeon card. https://www.amazon.com/gp/product/B00YONKZ72. I have the package xserver-xorg-video-nouveau installed. I removed all the Nvidia and purged all the packages. The logs I have found look like this (from log viewer): 12:10 PM radeon_dp_aux_transfer_native: 2510 callbacks suppressed 2:00 PM radeon_dp_aux_transfer_native: 1040 callbacks suppressed 2:01 PM [drm:radeon_dp_link_train [radeon]] *ERROR* displayport link status failed 2:01 PM [drm:radeon_dp_link_train [radeon]] *ERROR* clock recovery failed 2:01 PM [drm:radeon_dp_link_train [radeon]] *ERROR* displayport link status failed 2:01 PM [drm:radeon_dp_link_train [radeon]] *ERROR* clock recovery failed 2:05 PM radeon_dp_aux_transfer_native: 566 callbacks suppressed I searched Freedesktop's GitLab issues (https://gitlab.freedesktop.org/drm/nouveau/-/issues) related to "*ERROR* displayport link status failed" and "*ERROR* clock recovery failed". GitLab did not return any hits. I noticed I was missing the nouveau-firmware package. When I added it I lost the monitor completely. The monitor displayed a message similar to "No HDMI signal present", even during a reboot. nouveau-firmware definitely made things worse. Removing nouveau-firmware did not help. The "No HDMI signal" problem persisted. I had to switch back to the GeForce card and the Nvidia driver.
