Fatal server error:
no screens found
 
 
However, I can run X using the "radeon" driver if I do so with the following lines in my /etc/X11/XF86Config file:
Section "Device"
Identifier "* Generic VESA compatible"
Driver "radeon"
ChipID 0x4242
Option "AGPMode" "4"
Option "noaccel"
VideoRam 65536
# Insert Clocks lines here if appropriate
EndSection
 
Obviously, this does not help me too much as the acceleration is what I'm after. If I comment out the Option "noaccel" line, X starts but only the bottom half of the screen is displayed, and then the whole thing locks up.
 
I've tried DRI, assuming I've installed it correctly, it doesn't work either.
 
I'll take any suggestions here. I'd even be happy with "it doesn't work now but xxx release of xxx software will support it in the future." Any information will help. Thanks!

I've just discovered that the Radeon Mobility U1 chip is one and the same as the Radeon IGP 320M chip. So this may help in identifying the exact hardware in question. Any news on this front? Thanks!

My presario 2800 with ati radeon mobility 64mb works like a charm in
 
suse 8.1 pro , no more fucked up fonts , interlaced like mode n' blurred vision
 
*Chooose your ati in SAX2 , any monitor vim /.../XF86Config and add
the line crt screen within the ATI section
 
 
***With 3D enabled Quake3 dvd etc are flying , hell mode like.Smoothly

The Presario 2800 series uses Radeon Mobility M7 chips, which work fine in XFree86. The 2100 series uses the Radeon Mobility U1 (aka. Radeon IGP 320M) chips, which are completely unsupported. I have sent an email to ATI's developer relations address: devrel@ati.com
 
I am urging all readers of this post to PLEASE email ATI and ask them to either:
 
1. Release the technical specs to third-party developers sich as XI Graphics, DRI, or the XFree86 project
 
or
 
2. Develop their own proprietary drivers as nVidia has done.
 
If there is enough POLITE outcry, there may be some results. Please, if you have 60 seconds, fire them off a courteous email and then post a reply. Thank you all for your help!

Okay
 
You're welcome , though ahm sorry i wasnt be able to help you i
 
thought of that cause i got stuck in the ATI in general and not at
 
this very chip , well don't worry we'll see what we can do about it.
 
Farewell

Just to let everyone know, there is an ATI developer working with the XFree86 team to write an accelerated driver for the U1/3*0M chips. So far, it's working pretty well. They still need to fix some bugs in the 2D acceleration and then begin work taking advantage of the 3D acceleration. But it is promising!

do you know if this driver is publicly available yet? AFAIK it isn't because i cant find it anywhere

Any update on this yet?

Are the mobility chips supported in the Sheider Digital fglrx drivers? These work like a charm (after I patched the kernel to allow proper AGPGART support on my nForce2 chipset) for my 9500 Pro.

Hi,
 
I just installed FC3 in my laptop
 
http://eu.computers.toshiba-europe.com/cgi-bin/ToshibaCSG/product_page.jsp?z=78&PRODUCT_ID=15134
 
For graphics, it uses this:
 
manufacturer : ATI
type : ATI MOBILITY RADEON
memory amount : unshared 16 MB
memory type : DDR Video RAM
graphics accelerator : 64 bit
bus clock speed : 166 MHz
2D graphics accelerator : Yes
3D graphics accelerator : Yes
open GL support : Yes
direct 3D support : Yes
motion compensation : Yes
integrated TV encoder : Yes
reduce TV out flicker : Yes
multiple display support : Yes
triangle setup : Yes
connected bus : AGP bus
 
and my problem is I cant make it work to 1024*768
 
I havent found any driver.
 
Any news on this topic??
 
Thanks!
