Yes, I noticed also various specs can be found for the same type of machine on line
But we got to hang on with what lspci tells us in this case. That after all that IS this machine.
You are quite right. lspci generally
tells the truth of what is and what is not. There are some caveats here, though... for instance, if the configuration is wrong because modprobe "guessed" incorrectly, your hardware may still be at slight variance to the stuff lspci shows is loaded to support it. Also, some modules/drivers support a large family of hardware, some of which may have strange little individual quirks.
And you better believe me: The original Linux install is VERY basic and sure no X or any Desktop. Barely the kernel (a 2.6 version)
Its gone now of course and as I mentioned earlier on the supporting CD that came with it has nothing Linux.
Linux was installed to be removed! In the eyes of salesmen "No OS" doesn't sound as good.
Again, yeah, I do believe you, because I've seen something like this before, myself. It's not all that surprising - eMachines has traditionally been a, shall we say, lesser quality hardware platform.
IF it is a (failing)driver question (what I believe now it is) then PCLinuxOS can comfort itself as it is in good company as ALL Linux I tried on this machine (deb based as well as rpm based) shows the same failure. There seems simply not a correct driver for this setup. Hurdles past, it all runs fine be it that video is under performing. So I am for example unable to make a video with i.e. Cheese. It lacks the speed needed it seems. If I set Cheese to lower video specs, sound goes balony. It plays back the sound first and then the video! glxgears don't even think of starting up.
One of the things I keep telling folks who are considering Linux on a laptop is that prior effort in research can help avoid products whose support for Linux is iffy or non-existent. A great place to start is http://www.linux-laptop.net/
. A lot of their info is dated, but this just serves to show a history for different vendors' machines when taken in context. I have a report posted there on my old Gateway 3522GZ laptop, by the way, in the interest of full disclosure.
As you well know, it's virtually impossible to change video systems in most laptops (short of replacing the motherboard with a different one, and even that can be dicey).
I see, reading before I post, that you may have a solution in hand? Regardless of outcome, please continue to keep us advised of your progress (or lack of same). That way we all learn together. I do hope you've stumbled onto something that works consistently and well.
