To potential close voters: I have looked through My computer boots to a black screen, what options do I have to fix it? but neither nomodeset nor apci=off + nolapic worked.
I am trying to install Lubuntu on an ancient laptop (Pentium III Mobile, 384MB RAM). While I can boot it from the install DVD just fine, after the plymouth boot screen finishes, the display simply goes black. However, I am in fact able to get into tty1 and run commands. I attempted to run sudo service lightdm start, but it said that starting the job failed. I also tried startx, but it segfaulted.
Interestingly, if I do sudo shutdown -h now, the plymouth shutdown screen appears, so it seems to me that this is more of an X server issue than a video driver issue.
Any other boot parameters I can try?
