lspci detects that I am using: VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RV610 [Radeon HD 2400 XT]

Using this ATI graphic card turn the screen turn black after I have installed Triskquel in any mode ("Try Trisquel without installing", "Install Trisquel", or "Install Trisquel in text mode", etc.)

The problem figured out by having a close look at /var/log/Xorg.0.log.old and was solved by editing /etc/default/grub by adding "nomodeset" at the end of GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" so it looks like GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset".

A simple script could compare the graphic card to a list of cards that need "nomodeset" to work without proprietary Linux drivers.

Also, do not forget to run update-grub update-grub2.

Modifying /etd/default/grub and as described above, did not work when the metapackage "trisquel" (abrowser problem) is installed which receives error (see http://trisquel.info/en/issues/8058).

I can confirm this. However, my case has some more issues.

If you want, you can check out my case at https://trisquel.info/en/forum/mouse-pointer-and-graphical-issues-trisquel-60.

Have a nice day.
