FC14, Lenovo G575 (AMD Radeon HD 6310): how to change video driver?


Hello,

I recently bought my mon a Lenovo G575 and installed FC14
on it (burned ISO on DVD and installed from it).
As opposed to my desktop PC (also with FC14), during the boot
I see the blue then white bar advancing along the bottom
of the screen (just like under FC11) and not the filling drop
shape. And more importantly, the maximal resolution is 1024x768
despite the fact that the laptop is capable of higher resolution.
I also notice some "artifacts" being created after some mouse
movements and opening Evolution in Hebrew mode sometimes freezes
the laptop completely 1-2 minutes into the work with it.

I vaguely remember that during the installation there was some
selection related to video drivers and I think I choose the
default but I don't remember what were the choices.

How can I check what video driver is currently used?
How to upgrade it or replace it: is it just a simple
"yum install <some package>" or a more complicated procedure?

I never had to change video drivers (yet) and I'm worried of
somehow making a mistake that would render the system totally
unusable and require reinstall. BTW, if I make some
mistake in some configuration file, is there some keys combination
during boot to enter text-only mode?

TIA,
kaza.

Thanks John.

At what point the actual switch from the old driver to the new one occurs?
Is it on the next reboot or at some other point of time?

If something will go wrong and I'll get reboot ending with stuck GUI,
how to back out of it into something that works?
I understand that editing "/etc/inittab" and changing "runlevel"
to single ("1" on my desktop PC, haven't looked yet what's in the laptop)
results in text mode operation, what files related to video should I
preserve before the driver update to be able to restore the previous
operation if something goes wrong?

TIA,
kaza.

Hey kaza,

me and a few other people from the Internetz had the same problem with our Lenovo g575. At first I thougt about a problem with the graphic driver, then Gnome and so on... now we have the solution: You just need to go into your BIOS (F2) and enable the boot-option "network boot" and change it to the FIRST boot-point. Voíla, now your Ubuntu/Fedora/whatever works. Why? Don't ask me, aks Lenovo

God bless Linux,

Hotte
