Xorg !!! And ATI

[Ankit Malik]

My Config: ATI MACH 64 GX, LG Studioworks 563N, FC2 

My Problem: X doesnt start it says ATI card doesnt support 16 depth. I
copied XF86Config from Knoppix ( which incidently works for me in
FAILSAFE mode) That didnt work

I typed out 'system-config-display --set-driver=vesa' and then it
worked @ all colour modes but i am not getting
a) 1024x768 ( i had it in FC1 ;-(            
b)  Clear movies : its all choppy on my FC2 Box

Now now can anyone help me put ATI correctly since it used to work @
all depths in Windoze

XORG is the problem:!!!!!!!!!!!!!!!!!!!!

Did you try setting the depth to 32 or 24 then?

What is in your xorg.conf then?  This tells X what resolutions your monitor 
and card can handle.   X can be told to go ask the monitor over DDC what it 
can handle, for some cards and monitors that doesn't work and you need to 
tell X directly in the config file with HorizSync and VertRefresh lines.

vesa driver is a lowest common denominator driver, using your video BIOS to 
get modes and so on.  It doesn't support xv, which is what provides smooth 
accellerated video.  So the mere fact you are using the vesa X driver means 
many things will be unsupported and sluggish.  (Hey, it's the same in 
XFree86).

More info and less complaining would help people help you.

How did you work that out?  That's the second time in two days I see people 
blaming xorg as The Demon.  Why don't you find out more about where your 
problem is coming from before choosing what to curse out.

I agree with the OP.
The Xorg "ati" driver appears to me to be deficient,
at least with the ATI Rage Mobility card.
I am also unable to get more than 8 bits at 1024x480
on my Sony C1VFK Picturebook with Xorg under FC2,
whereas I had 16 bits with this screen
with XFree86 under FC1.

If I use the same config file (calling it xorg.conf)
that I used successfully with XFree86 with DefaultDepth 16,
I get a shrinking black oval which becomes a blank white screen.
But there is no error indicated in Xorg.0.log .
According to this, all is well.

In my view, that must be a bug in Xorg.

However, I'm more than happy to pursue any suggestion you might have.

IIRC you were the first person mentioned above ;-)

That is an unusual resolution, I wonder if that is something to do with the 
problem.  How much video memory is on the video card?  AGP apeture size in 
BIOS?  When you ask for 16 bits NOT using the config from yesteryear, what do 
you see in the xorg log file as the reason it rejected 16bpp?  Did you try 32 
or 24 bpp?  What happens if you ask for the same deal using a "normal" 
resolution like 1024x768 (useless as that may be on your widescreen display).

I have seen this on my Dell (using XF86 at that time....) it seems to be 
caused by the video chip stopping driving the LCD while the backlight is 
still on.  From X's point of view everything IS well, it asked for such and 
such a video mode and as far as it can tell, got it.  You can try Fn-F8 or 
whatever it is in your BIOS to flip between CRT and LCD, this something 
resets the chip from the BIOS code providing output again.

Well, xorg's ATI driver seems to have changed functionality from what you were 
last using.  It can be a bug or just something changed: since xorg IS XFree86 
branched at a certain point blaming "xorg" makes no sense to me.
