No Screens Defined. Thinkpad T41 With Ati Mobility Radeon 7500
 

Hi,

I'm trying to install the ATI driver on my Thinkpad T41 and I keep getting the No Screens Defined Error. I've been following the ATI driver installation instructions on the The Jem Report to a tee and I still get the No Screens Defined error. Any help would be appreciated.

Here is my xorg.conf file:

When X windows starts up, it tries to setup using your default modeline. When that doesn't work, it tries another, then another until your list runs out. Look through the /var/logs/xorg.0.log to verify that. Perhaps there is another reason.

I highlighted the lines that may need tweaking. I would recommend using the gtf program yourself.
gtf 1024 768 56 -x # This will set up a modeline for 1024x768@56.
The line may start like "Modeline "1024x768_56 ". Comment out the original line, and edit out the "_56" part.
Compare your results with what yast produced.

Pay particular attention to the end part. "-hsync -vsync"
If those are wrong, The X server won't start.

Good Luck!

I am also having the same problem with my laptop (T41) with the "fglrx" driver.
here is the error - No Devices Detected
If i use the "redeon" driver X works fine.

Dude if I'm not mistaken, the 7500 is not supported by the proprietary ATI drivers, it's legacy now and simply too old.

You have to use the stock driver that comes with xorg :(

i have compaq n610c with P4m 1.8ghz, 512mb ddr266 and mobility radion 7500 32mb and im having similar griefs over the card. people that say its too old are simply ignorant and probably have no clues about the capabilities of this chip. this chip marvelously keeps up with newer directx games thanks to the clever ati drivers, on windows that is (yeah you have to forget about aa and high texture resolutions, and you decide resolution vs. features alot).
as far as linux goes, xorg or xfree86 is your choice, BUT here is my practical experience with both:
i use debian. on xfree86 driver the fps is MUCH higher and certain features are rendered more properly such as the reflections, but newer games like doom3 and quake4 do not work at all dispite the fact they work marvelously on windows on this machine. on xorg driver the fps is much lower but newer games like UT2004 can be played using opengl, meaning the necessary features are supported. in case with debian etch you cant really play anything else because its still very unstable.
both were tested using the 2.6 kernels btw.
overall the perfomance of either is very inferior to what i get on windows sadly. it is the opposite with nvidia cards on my desktops.
i am still hopeful ati will have some pity for us and include support for these chips in their linux drivers.

I never said the card is poor in terms of capabilities, simply that it's old enough from ATI's perspective not to have it included in their proprietary drivers.

Perhaps you should think before calling people ignorant. :mad:
