MX Linux 18 Laptop Computer Hung Up With Black Screen

#1 Post by Falcon »

Hi,

I'm new to MX Linux and I posted a question about printer installation in the Hardware forum using my desktop computer. I left the laptop that I just installed MX Linux on a short time ago running until I got an answer to my question. This took a couple of hours, and when I got the answer, I went back to the laptop and found that the screen was black. That's most likely because the screen shuts off to save battery power. I tapped the touchpad but nothing happened. In the past when the computer had Windows 7 installed if this occurred, I only had to press the ESC key and the computer would come back to life. That didn't work this time, nor did any other keystrokes. Is there a particular key combination that would normally be used to poke the OS and get it running again? I was logged in as an administrator so I'm afraid to force a power off.

Thanks...!!!

I gave the power button a try but that didn't work. Any other ideas?

Well, after going through all of the options in the Manual to try to get the OS back, I finally bit the bullet and pressed and held the Power button until the computer turned off. When I powered back up, everything seemed to be okay.

On another note, how is the computer normally brought out of Suspend mode or Hibernate mode?

Normally - you would just 'pres any key', but sometimes, that doesn't work.

so - you then press the power for for 2-3s, but no longer:
- any more, like 5-6s will power-off that machine.

it's an Tricky one, for sure, but don't compare it to any Windows Scenario, though,
- even though it's an similar situation, in hand.
that Windows System is an highly customized environment,
& where-as the Linux System is just plain vanilla, & the result(s) are Not the same Thing.

Thanks for the help guys. After trying to solve this problem using ideas from the manual, I just forced a power off as described above. Everything seemed to be okay when I powered up again. I'm wondering if the computer went into Hibernate mode, rather than Suspend mode, since it seemed that the OS wasn't damaged like the manual said that it could be from a forced shutdown. The first thing that I did was to go into the Power Management feature and it looked like the Suspend and Hibernate settings were set to NEVER, so I don't know why the computer went into one of these states in the first place.

I just started to read and follow the manual from page 1, so I hadn't gotten to the section on Power Management when I ran into this. MX Linux boots up so quickly that there really isn't any need for me to use the Suspend or Hibernate modes, anyway.

Use 'suspend' - it simply works - any key tap wakes it up

If this happens again, try to enter your password and hit 'Enter' without seeing anything on-screen.

If you didn't try to wake up the screen by using a dead-key (eg Shift or Control) and instead used a character key, type on the keyboard Control-U just to clear the (non-visible) password field.

You can try the above at any time by manually suspending the computer through the shutdown menu.
