I installed F12. While doing some basic tweaks, nautilus, panel, display etc I got a pop-up: Additional Firmware Required... "to make hardware in this computer function correctly". No more detail than that. Like signing a blank check so I said "go for it". When I rebooted the display was hosed. Like the refresh rate was wrong. So off to xorg.conf to fix it. There is no xorg.conf. After four hours of searching forums and google I gave up and reinstalled (only an hour). This time I made a backup (cp -a) before letting F12 fix the non-existent problem. Tried again very carefully to be sure that what killed the display was the additional firmware. True. That kills my display. Only problem is the backup cp -a when copied back in would boot but would not let me log in!? I could boot "single" change the password, but it said that was already the password.
Oh well, for me F12 is a "one-day-distro". I have multiple partitions with Ubuntu, Mandriva, SuSE, Slitaz ... My first Linux was Fedora Core 4 and I will try the next Fedora release. For now back to Ubuntu 9.04. I'm still testing 9.10.
My graphics is on-board Intel. I think it's 965G chipset. This is a Dell E520N.
How would I tell what not to do that firmware addition?
Where could I tweak the refresh rate to repair the damage done?
Links to instructions/how-to would be great. Thanks.
