I followed both Sharad's and A.B.'s answers (both of them) on a previous question about Kubuntu. I then rebooted LXDE and managed to get into Grub, I then selected to run Ubuntu, normally (i.e., the default option given) and while it seemed to be loading normally (i.e., it showed the Ubuntu logo with the five circles that change their colour to reflect that Ubuntu is loading) for a while after that, it eventually left me at a blank black screen with only my mouse cursor visible. I waited patiently for this to pass, I assumed it was only temporary but it didn't pass, after twenty minutes of waiting nothing happened. So at this time I am on my live USB (in "Try Ubuntu" mode) and hoping someone in this grand community can help me. I don't have anything on my Ubuntu installation I'd deeply lament being rid of, aside from my MediaWiki installation (if there's a way to do a mysql dump from my live USB I'd love to hear it).
Following 2, issues
When following 2, this is what editing the Ubuntu boot option gives
Changing quiet splash
to nomodeset
allows me to boot (and even login) but the computer is incredibly laggy, graphics-wise. Like there's trails of black pixels left by the mouse cursor. While the other options like acpi=off
or nolapic
gets me to the login window, but freezes and reverts to the screen described at the start of this question. Everything is so laggy and prone to these stream of black pixels following my mouse cursor I can't even open a web browser and read stuff in it. See when I open a web browser, it opens but the blank pixels pop up when I scroll down in the browser. So I think the best option is for someone to work out how I might fix the problem that occurred with the changes recommended (in the answers) in the previous question I linked.
nomodset
and if that did not work, try withacpi = off
andnolapic
as described in askubuntu.com/questions/162075/…acpi=off
andnolapic
. I then logged out of the live session and rebooted from my hard drive and I experienced the same error again.
