[solved] blinking monitor
The past few weeks my Lenovo monitor would occasionally blink off (black) for a second, then return to a good picture. This happens sporadically, whether the monitor has just turned on or is warm.
The monitor is 6 months old; the display is onboard in my aged Gateway SX2380, operating under Mate 19.3, constantly updated. I wanted to call the seller (MicroCenter) to ask about their warrantee but they no longer list a phone#, demanding that the customer came in person, however distant and inconvenient. My last purchase there.
Does this sound like a failing monitor? Might it be time to add a display board?

Re: blinking monitor
Find a way to test this monitor on another machine, whether laptop of otherwise; that is the ultimate diagnostic step to take here, IMO.
A loose or broken (physical) connection can cause this, however.

It might be a cable issue.

Re: blinking monitor
It is not unusual to have people posting about having graphic related issues when their computer's root partition is this full. Because of the way SSD's are designed, they can start running into performance issues when they are more than 75% full. The manufacturer of mine (Samsung) recommends keeping them less than 2/3's (66%) full which is the recommendation I pass along to others. Older, unused kernels can take up more space that people realize. Here are some other tips How to Clean Linux Mint Safely.
Partition:
ID-1: / size: 95.62 GiB used: 76.78 GiB (80.3%) fs: ext4 dev: /dev/sdb1
Perhaps clearing some space will help clear this issue.

Re: blinking monitor
I'm wondering if I should tank my root partition just so I can experience all the weirdness I keep hearing about, because I keep forgetting this is a thing.
I guess OP could run
df -h /
in a terminal, so we can see whether space is the issue.I'm also Terminalforlife on GitHub.
Re: blinking monitor
It's not so much physical space available as it is the percentage of space available. This article, Why Solid-State Drives Slow Down As You Fill Them Up, explains at 75% full there is a documented slowdown on consumer drives.

Re: blinking monitor
I'm familiar with the performance drop of SSDs, but I've never heard nor read of all this other stuff happening; sounds a little iffy, to me. I'll keep an eye out, though -- thanks for the info.

Re: blinking monitor
I did the recommended procedures for 'cleaning' the SSD, now down to 44% usage, but the monitor still blinks.
Re: blinking monitor
Do you have a different cable you can try? Termy suggested that earlier and I would second that recommendation.

Re: [solved] blinking monitor
After cleaning the SSD down to 44%, I switched cables and utilized the VGA connections on the monitor and computer. The problem has not recurred now for the past two days.

Re: [solved] blinking monitor
I see you edited the title of this post so I presume you consider this solved. The way the forum works is that only changes the title of that individual post. I realize that can be a little confusing. To mark the thread solved, you need to edit the title of the very first post in this thread because the title of the first post is what shows when people pull up the thread in searches.oxygenfarm wrote: ⤴Thu Jan 14, 2021 12:26 pm After cleaning the SSD down to 44%, I switched cables and utilized the VGA connections on the monitor and computer.
