Screen remains dark after blanking


Best Answer RockinBodi, 17 September 2017 - 10:52 PM

Ha, I don't think the ssh thing is for me.  I just upped the monitor sleep to 15 minutes and won't leave chrome open when I go to bed or to work.  Issue solved a lot simpler, and I can live within those confines.

 

Thanks guys for trying; I thought it might have been a simple setting I was missing, but it seems to be some weird bug with an old laptop.

Hi all.  Most know I have Bodhi on my little Lenovo and that one has been rock solid.  I've also gone and put Bodhi on my workhorse laptop and I've run into an issue with it I've sort of diagnosed on my end, but I'm hoping some with more experience can confirm whether or not I am right.  Basically what happens is I have my screen set to blank after about 6 minutes of inactivity.  95% of the time, give the mouse a shake and it comes back.  That other 5%, the screen is permanently off and nothing I do gets it to come back, so I have to manually power down by holding the power key and then turning the computer back on.  

 

I want to say what causes it is walking away and leaving Google Chrome open, but I've done that before and it does come back on, so its not a consistent behavior.  I don't know if there is a combination of applications causing it.  Just now, I had Chrome, audicious, and the file manager open while I was working on student grades (hard copies) and the screen went blank.  Went to shake the mouse to see what I was listening to, and the screen didn't come back.  I do know going to bed at night, if I close all programs and then come back in the morning, I've not had any issues, so it must be some program causing it, just not every time the program is running.

had similar issue. i solved it by tweaking the blanking and the locking settings. it finally worked. i now have it setup as follows:

 

- locking: lock on suspend

- screen saver: enable screen blanking ONLY (the other options are not checked)

I would suggest, if michmanbiker's comment doesn't work, that you look for the various log files to see if anything is cropping up. Also, have you tried Ctrl+Alt+F2 to attempt to get to a virtual terminal? If that gets a response, you can then Ctrl+Alt+F7 to get back to the GUI. I still have to imagine there is something being written to a log file somewhere that would be of use to you or people that actually know what they are doing (people smarter than me). :)

@michman tried to make sure it didn't lock or anything, just blank out, and it still occurred.  Again, chrome was open when this occurred.

 

@birdmun I will give a CTRL command a try next time.  I forgot what it was so I couldn't test it.  I'll be ready next time and see if that can snap it out of whatever happens.

 

If that fails, I'll have to get a log somehow of what's going on or why.

As an addition, Ctrl+Alt+F1 through Ctrl+Alt+F6 are typically all virtual terminals accessible at any time.

 

WAY OFF TOPIC

There was a time when computers with linux were specifically sold as multi user workstations and made use of the multiple terminal capability. With some other Desktop Environments/Window Managers you can actually access Crtl+Alt+F7 through Ctrl+Alt+F12 as GUIs. As I understand it, Enlightenment and therefore moksha do not support multiple log ins to multiple virtual desktops in this manner.

Ok, its a weird bug whatever it is, and like I said, I don't know what triggers it since it doesn't happen every time.  Same scenario...working on grades, was reading over stuff and writing it down in the gradebook and my music stopped.  Sure enough the screen was dark, and that was it.  So whatever happens, it totally kills any app running and the only thing to do is turn off the computer by holding the power button.  Its not a suspend/hibernate issue since I don't have those enabled.

 

How would I get  a log for such a thing because its so random?  Its not really good for the computer to do such a hard shutdown with stuff running.

 

EDIT: the CTRL commands do nothing to wake the system/screen.  My keyboard still lights up, but otherwise its like nothing is happening.

I think maybe ~/.xsessions-errors.old

 

Hopefully some more experienced eyes will fall upon this thread.

I'm really not sure where to start with this one. Don't have this issue on any of my four laptops here :(

Its not like it happens every time, so I can live with it, and it never happens if I don't leave apps open.  You never know with older laptops what will and won't work or the why or how of something.  This one's going on seven years now.

If you have more than one computer I would attempt to debug this issue by sshing into the computer that has frozen up from another machine and trying to see what is going on and/or killing processes that are highly suspect trouble makers: such as Chrome. You should in theory be able to ssh into the frozen machine. If you can ssh into the frozen machine note that you can also force it to reboot or shutdown without powering down. 

 

Note: on both machines you need openssh-server installed to do this:

sudo apt-get install openssh-server

If you are willing to try this, do you know or are able to figure out how to ssh into another machine? Remember search engines are your friends  ;)

 

Also note that to truly debug this issue using ssh requires familiarity and some comfort level with CLI and some knowledge of Linux and linux commands.

Could it be some memory going bad? The more programs you have open, the more memory will be used... 

 

If you boot to the live ISO in Legacy mode (not UEFI mode), there is an option to run 'memtest'. You've probably seen it on other distro's too. Since the problem is intermittent it may not pick it up right away, but it might pick something up through a few runs. Could be worth a try if you're still interested in looking into it.
