Description

At first, I thought I had problems with grub:
#204: Configure grub for dual boot
but it seems that grub is properly configured after all.
The problem is that the grub menu doesn't display when I boot the computer.
It seems to be a problem with the video card. When using linux on that computer, I saw some strange artifacts within console and man pages (some words were truncated).

I need to find out what video card is inside (it's an Acer computer, ready assembled) and figure out what driver problem there may be.

I think this is related:

uncommenting:

#6 worked for me. I can now see the grub menu!

Look at the two screenshots posted in #2 above.

In the first one, you can see file and directory listing in the konsole. Notice that all the long directory names are truncated at the end. At first, I thought it was a feature!! But no. On the screenshot, you can see the following directory names truncated:

.gstreamer-0.4/
.kde/
.locale/
.macromedia/
.pulse/
...
augustin/
.directory/
lost+found/

In the second screenshot, you can see a man page within Konsole. Look at

man grub-setup
in your own console and see how the long options are all truncated.

Also, I had to modify a configuration file with vi, and similarly, some words were truncated, but I could read all the word if I moved my cursor from one letter to the next, as if there was not enough space to show the whole word at once...

What could cause this??
