Black screen/no full boot?
« on: June 17, 2015, 08:47:24 am »
Hello,

First post here and it starts with a problem.  ::) I've been using Peppermint 5 on and off for a year and now upgraded to version 6 and really like it! The problem is that after I've been using it for a while the screen turns black on boot. The computer doesn't seem to reach the full boot since one touch on the power button and it shuts down. I'm an old laptop Dell inspiron 1525 and as far as I collect I had this same problem when using Ubuntu 12.04 or/and 14.04.

I got some tips on Google+ but there is no way I can use them (for example [sudo service lightdm restart] since the screen is black and the system doesn't respond. Someone mentioned Nomodeset but I haven't got a clue what that is.

Anyone recognizing this problem? Any tips? (Right now I'm on my Lubuntu live-USB.)

So I guess everyone is on vacation or just haven't got a clue? I still haven't solved the problem and would appreciate some form of help.

OK, you want to try the nomodeset kernel boot parameter ?

Here's how

The following instructions are for a single boot ONLY .. so you'll have to do this EVERY time you boot .. but if it works, we can add nomodeset permanently to the kernel boot line.

Turn ON your PC, and as soon as your BIOS POST screen disappears, press the SHIFT key and hold it, until you are presented with the GRUB menu .. SIMILAR to this:
(you won't have long to hit the shift key, and the timing can be a little awkward, so it may even be easier to hit AND HOLD the Shift key DURING the BIOS POST .. ie. immediately after turning on your PC)


Select the 'default' kernel (usually the top one), and rather than pressing enter, press E to edit.

You will be presented with a screen SIMILAR to this:


Press DOWN ARROW until you get to the line that starts with:

Quote
linux /boot

and press the END key to position the cursor at the end of the that line... it *usually* ends with “quiet splash”.

Now you can enter additional kernel boot options... so add nomodeset as in the above screenshot .. so it now reads:

Quote
quiet splash nomodeset
(doesn't matter if it moves down a line, as long as there is a space between splash and nomodeset)

Now hit Ctrl+X to boot.



Let us know if that helped, and we'll go from there.
