Yet another question about black screen with Ubuntu 12.04
I've installed Ubuntu 12.04 after fighting with the "black screen" issues.
This is what I did:
I firstly used the nomodeset with the LiveCD, and then I modified one line of the /etc/default/grub file like this (following internet advices):
I have screen resolution problems, so I modified the /etc/rc.local (also following internet tips), adding this two lines:
I tried using this solution http://bit.ly/Yy1lMe (the first script), even though I have no idea what I does, but I doesn't work.
I'm going nuts!! Every time I forgot to disable the screensaver, and I'm away, I come back to find the black screen and I have to turn it off!! Help please!!!
What can I do? any ideas??
I'm using a Notebook Acer Aspire 5734Z. Let me know what other information do you need.
Whenever I have screen resolutions, I usually create and customize an /etc/X11/xorg.conf file.
Unfortunately, creating this file is super complicated, as you need to detail every last bit about your hardware, including video drivers, native resolutions, and every single last modeline you wish to support.
There are howtos out there on the web for how to do this.
First, create the file automatically:
If you're going to create modelines, this modeline calculator is invaluable:
Anyways, this road takes quite a bit of effort... I've been doing this since 2007 and still have trouble in doing so.
The plus side is that you can specify which video driver you wish to use, and remove superfluous options.
I could not add one single thing to what has already just been said ... except to suggest that you might wish to get a Knoppix DVD and boot it up on your system, then see what sort of configuration it came up with, assuming that it somehow succeeded in presenting you with a GUI screen that works.
Also: the key-sequence Ctrl+Alt+1..4 usually cycles between the GUI screen and one-or-more terminal sessions. Try it. If it does, then you can be sure that XOrg/X11 is in control, even though it does not yet have settings which allow it to correctly drive your particular hardware. That, in and of itself, is a major conclusion.
Sounds like complicate :(
I'll try other distros... :( I have tried Linux Mint and Trisquel before, and had the same problems though. I'll try non-ubuntu based distros and see what happens. It's a pity this thing still happens, I thought with the new ubuntu version this issue would have been fixed :(
