separating the following phrases from those which came before.
I guess this is a problem similar to the one I had.
When you're asked to select your language and then select Try Trisquel
without installing and many other options. Highlight Try Trisquel without
installing, then press F6, you should see a list with the word nomodeset,
select this word (if the list doesn't have the mentioned word, or if you
don't see a list, press Escape and try one of the neighboring keys, that is,
F5 or F7).
After selecting nomodeset, this word will be marked with an X. Now, just exit
the list (by pressing Escape, if you didn't do it yet). Select Try Trisquel
without installing and you should at least be able to use or install
GNU+Linux Trisquel, although you won't have higher screen resolutions
available.
In the case of the live CDs, the nomodeset option will be disabled each time
the live operating system is shut down.
After installing GNU+Linux Trisquel, if you can't go past the login screen
when starting the installed operating system, you'll have two options:
First option
Start your live CD (you may have to use the method above), enter the recently
installed operating system's partition (by double clicking Computer and then
double clicking on the file system containing your GNU+Linux installation (if
you're not sure, try to remember where you asked for the installer to save
it). Inside this partition, double click on a folder called etc, then on X11,
in this folder, try to find a file named exactly xorg.conf, if the file
exists, please continue reading, otherwise, go to the other option. Press the
right mouse button inside the folder's content and left click Open with a
terminal, then type:
sudo mv "xorg.conf" "xorg.conf~"
Due to the fact that you're using a live operating system, it won't ask for
your password, but most of the times, it does.
Now, restart your computer and try to start the installed operating system.
If something unusual happens, start your computer using the live operating
system, go to the folder where the xorg.conf file was, open the folder with a
terminal and type:
sudo mv "xorg.conf~" "xorg.conf"
If you need more information about each one of this commands, just type:
man sudo
Or:
man mv
Second option
The second option is a workaround for those people who must not waste any
important time, but this comes with the price of limited graphical quality.
Start your computer using the live operating system, open the partition of
the recently installed operating system, open the boot folder, then the grub
folder. Right click the folder's content and select Open with a terminal and
type:
sudo nano "grub.cfg"
You will see a simple text editor called Nano. This text editor opened the
grub.cfg file. This file has informations which, along other things, makes
the GRUB (your operating system boot loader) display a list of available
operating systems, as well as, to control how they will start.
What we're going to do here is simply as equal as what we did in the very
beginning of this comment. While Nano has grub.cfg opened, press Ctrl+W.
Notice that, below Nano's window, you should see a word similar to Search and
a blinking pointer. If so, type:
menuentry 'Trisquel GNU/Linux
If you want to search for more matches, press Ctrl+W and see if Nano's window
shows you something more. In this case, I'm assuming that you just have one
match.
Below menuentry 'Trisquel GNU/Linux, you'll see various lines which are
distant from the start of the line mentioned above. These lines make
reference to the menu entry above, that said, to the Trisquel GNU/Linux menu
entry. One of these lines starts with the word linux, place the blinking
pointer in this line, and between the words quiet and splash, then type:
nomodeset
Remember to separate each word with one space. The text should change from
this:
quiet splash
To this:
quiet nomodeset splash
Now press Ctrl+O. If Nano asks if you want to overwrite the existing file,
press Y.
Now just start your computer using the recently installed operating system.
When GRUB appears, and if you have more than one operating system installed,
remember to select the exact menu entry which you edited.
Now you should be able to go past the login screen.
-- End --
The problem with the second option is that, if you update your operating
system, and if this update changes the kernel version of the operating
system, or if it says that it updated grub, you'll have to redo the second
option.
Best regards, ADFENO.
Have a nice day.
