Black screen, nvidia-modeset : ERROR: GPU:0 Idling display engine time out

How do I troubleshoot/fix this issue?

Using a nvidia GPU, the system is able to show the motherboard firmware logo and Grub screen. After a Ubuntu version is selected, either 18.04 or 20.01, Ubuntu login screen can't be shown. Instead, I see a black screen appears complaining that nvidia-modeset : ERROR: GPU:0 Idling display engine time out three times (see attached photo), followed by a pure black screen with the GPU revving up to full fan speed continuously and becoming very hot. I had to press the power button to shut down the system.

error

This GPU had worked well prior to this incident. The Ubuntu system is able to properly boot up when the GPU is removed and when the Intel CPU's integrated graphics is plugged in to the monitor. IGPU is disabled.

Installed nvidia packages:

I had this GPU tested on a Windows system, which was able to display boot screen, login screen and desktop. However, the display artifacts persisted. Also, I suspect Windows was able to step down the resolution.

I came across this youtube video showing the same display artifacts and using NVidea MOD and MATS found the issue originated at one of the GPU VRAMs. Replacing the VRAM fixed the display issue.

As this GPU has been well maintained, I wondered if the GPU display fault was due to faulty interconnects. I came across this other youtube video that showed that reheating the GPU board with a heat gun for 6 to 8 mins had a 10% success rate of fixing the GPU card. He recommended this treatment as a last resort. I heated the GPU side of the card with a heat gun for around 4 mins. Thereafter, I flipped the card over and heated it for another 2 mins or so. After the GPU card cooled down, I tested it and found that its functionality is restored. The reheating procedure fixed the GPU card. Earlier, the GPU card was cleaned but was not heated treated; that procedure alone did not fix the GPU.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
