Hello again! New problem.
I’m using an Acer monitor and I have an HP computer.
Running antiX-21, the full install.Last night my monitor kept going blank randomly while I was trying to stream a TV show on firefox-esr. It would say something like “no input” (I can’t remember the actual error message). Basically the same thing it would do if I unplugged it from the PC. I could still hear the audio playing from my show, but the monitor went blank and wouldn’t turn back on no matter what I did. I’m still new to Rox / antiX in general and don’t know how to navigate blind, so I was forced to hard reboot multiple times.
At first I figured it was a hardware issue, but the screen seems to work fine when I run my other (Windows) hard drive. I had it playing videos for hours today with no issue. I checked internally and everything seems to be hooked up securely. So now I’m wondering if it’s a software problem.
The machine was running fine for a couple weeks, the issue just started yesterday.
My memory is hazy, but I think I was trying out a new desktop (possibly the zzz-icewm one?). I may also have played around with a driver setting while installing a new program… but I don’t remember. I have a vague memory of having to choose between 0 NVIDIA and 1 NVIDIA, but I don’t remember why or even what program it was pertaining to. And I did a system update yesterday too, so maybe that changed something for the worse.
How can I diagnose the issue?
Thanks,

If there’s no hardware problem (the device works fine using another OS), my reasoning is that it’s not a video driver problem (or else it would not show any image on the TV…
1- The cable could have been incorectly conected (a little loose) either on the pc or tv side
2- are you sure it the problems were random? Could it be the screen blanking kicking in? To try to make sure it wasn’t this; Menu > Control Center > Session > The icon with a monitor with a yellow sun inside it > Tunr off screen blamk timout timeout > Click “Apply”P.
Thanks, P. I turned off the screen blanking. It definitely could’ve been that.
Actually, what I think I will do is turn it on and set it to go off as soon as possible (I’m assuming 1 minute is an option) and see if it exhibits the same behaviour. If so, I can simply turn it off.
I just spoke with my computer-savvy housemate and he said it could also be that the X something or other (x-server, maybe?) crashed because apparently linux doesn’t interface well with AMD?
Update: Okay. So the screen blank timeout thing DID behave very similarly to what happened last night: the monitor shut off and gave me a “no input” message. However, there is one important difference: when I tried it just now, the keyboard was responsive. I hit the enter key and the screen turned back on and everything was fine! Whereas last night, there was nothing I could do to get input to the screen to turn back on.

In some cases there are issues with very new hardware, that applies to any of the big names.
And there are a lot of complaints about AMD drivers. Especialy for Ryzen.
Propriety drivers are provided by AMD so better say AMD does not support linus as well as needed by users.
Maybe they see the linux desktop market as very small so only put a lot of effort in to windoze support..

Hi, if it is HW-compatibility issue then upgrading to a newer kernel (if not already running the latest available) may help.

I sort of lost interest in this problem because it stopped happening for a while. It’s only happened maybe once in the last two weeks or so, until it happened twice tonight in rapid succession again.
Once it happens, I can’t do anything about it. The keyboard and (as far as I can tell) the mouse are completely non-functional. The machine won’t respond to any commands.
It is always while I am watching videos. All of a sudden the screen says “No Input” and goes blank. I can still hear the audio of the video, which will play for a few minutes after the screen stops working. Then a few seconds of the audio starts looping, as if the video is skipping like a broken record, then it goes silent and nothing happens anymore. The machine is still running, but the screen is gone and nothing works, so my only option is to hold down the power button until it shuts off.
It’s definitely not anti-X, because I’ve been trying out a different OS (Lubuntu) for the past few weeks. But I’m wondering if it’s possibly a linux issue still, because it’s weird to me that it never happens while I’m using other programs, only when watching videos. Although I don’t trust this machine enough right now to do much else, so there’s a chance that is just a coincidence… but like, I keep it running all day and it never does this except when I’m actively playing a video. The computer is a rescue from the trash, so I’m not ruling out a hardware issue either, but I am having trouble figuring out what that could be. The OS is brand-spanking new and fully upgraded.
Suggestions?

Turn off screensaver if you have it installed and turned on.
Hopefully. You have apt update and apt dist-upgrade already or already used auto updater on your antiX install.
Otherwise. Go into session in AntiX Control Center and
Set Screen Blanking
Turn function to off.This tech friend that suggest amd and linux don’t play well together. Don’t sound right to me at all.
Yes. Linux works very well on a Ryzen CPU and AMD graphics. It is especially nice because the graphics drivers are open source and work perfectly with things like Wayland desktops and are nearly as fast as Nvidia without needing their closed source binary only drivers.
Edit: Did not read your last post. No signal is always hardware. I go through this on my motorcycle shop Desktop computer also with mix and match componenets.

Did you hint that the same issue would also happen when using Lubuntu?
this problem … it stopped happening for a while. It’s only happened maybe once in the last two weeks or so, until it happened twice tonight in rapid succession again.

I don’t have an answer either, but since I stumble upon your post, I want to share my experience.
1. I encountered similar problems on my Thinkpad X60 and T61p. But the issue happened so rarely – perhaps once per several weeks or even months – so I was not able to recognize a pattern, let alone to reproduce it.
2. When the monitor goes blank, it is unlikely to be a monitor hardware issue, because my Thinkpad laptop’s built-in monitor and the external monitor BOTH go blank. So, it seems more like an issue on the Linux side, which somehow cuts off the video output. (My same Thinkpad X60 was running Windows for years and never encountered such an issue.)
3. When the monitor goes blank, it is not the normal screen blank kicking in, otherwise you would be able to turn it back on after you move the mouse or type some keys. Besides, I also tried setting the screen blank timer to 1 minute, and watch some youtube video. It seems the desktop environment is smart enough to NOT turn off my screen when I’m watching video.
4. That being said, the issue MIGHT still be triggered by the blank screen timer, because I habitually keep my daily driver powered on 7×24, and the issue – when it happens – tends to be discovered when I came back the next day trying to wake up my computer but it remained blank.
5. When the monitor goes blank, the mouse and keyboard were not able to wake up the screen, but they might still be able to generate input, it is just that we can not see its effect via screen. So, the recovery method has always been perform a power-off and then power-on. However, when the latest incident happened at months ago on my Thinkpad T61p, I happened to notice that, albeit losing screen output and possibly also the keyboard and mouse input, my T61p actually remains functioning, because I can use “ssh” to login to it remotely from my another computer. So, as a weird experiment, I keep it running, and use it that way. Now, my T61p remains on for 281 days, and still counting. Just so you know, the issue was really just affecting the video sub-system, not the entire Linux.
Just FWIW.
Are you using chrome or chrome based browser to watch video, the issue seems very familiar/similar to my experience before
switching off browser hardware acceleration, and removing chrome cache every start. The cache often gets Gigabyte huge in an
hour or so of video, generaly acceleration setting is on by default.
Since doing above neither vivaldi nor UngoogledChromium have locked me up.Another issue can be having debian java 11, on the system, that also caused random lock ups, to be fair, mostly in tandem with
libreoffice (known bug) for which it is non recommended by LO Org.Put in desktop session startup file.
#delete chromium cache at startup
rm -rf ~/.cache/chromiumYou can also have chromium cache in temp, must change from demo to your username as appropriate, either has the added advantage of removing many tracking vectors.
Vectors, because the startup cache contains a lot of code useful to a tracker script. It is more like a super supercookie. It is not deleted by the browser on closing
intended to never expire. Applies to Firefox or other browsers too…#Moves chromium cache to temp, thanks to xecure
#First line only needed if chromium cache exists in home
[ -d “$HOME/.cache/chromium” ] && rm -rf $HOME/.cache/chromium
mkdir -p /tmp/demo/.cache/chromium && ln -sf /tmp/demo/.cache/chromium /home/herold/.cache/chromium#mkdir -p /tmp/demo/.cache/chromium/Default && ln -sf /tmp/demo/.cache/chromium/Default /home/demo/.cache/chromium/DefaultThanks for the suggestions, ModdIt!
I’ve turned off hardware acceleration in firefox. Gonna have the machine watch a pile of videos today and see if the issue happens again.
BTW, I *am* exclusively using firefox. I set it to destroy all cookies on shut down and ask websites not to track me etc… is that not sufficient protection against super cookies? If it’s still a problem after turning off the hardware acceleration, I can try clearing the cache more frequently moving forward. Seems like a bit of an annoying work-around though, rather than a solution.
If it’s the debian java 11, how do I check for that? (If it IS a problem, I’ll want to know how to deal with it, but I won’t trouble you for that information until I know.) I haven’t had the problem with libreoffice, just video playback. But I also haven’t used libreoffice all that much on this machine yet.
I’m sorry we seem to be in the same boat, Rayluo… although it’s nice to have the company. Maybe we can figure it out together.
I initially suspected the blank screen timer as well, but I turned it off and it would still happen. It’s also happened when the timer was set to something ridiculous like 3 hours, when I’d only been using the machine for a few minutes. AND it happens at completely random intervals. i.e. it’s not every 10 minutes or whatever, it just happens after 47 minutes or 30 seconds or any random amount of time. So I don’t think it’s that.
I’m going to try some of ModdIt’s suggestions and report back.
