Xorg: Resolution and 3D with Xorg ATI standard driver?


Ok, there are about 296 threads on getting ATI graphics cards running in Slack 10. But -- forgive me, if I overlooked something relevant -- I was unable to find the piece I need.


So:
How can I get / what do I have to add to /etc/X11/xorg.conf to get
- a resolution of 1280x1024 at 24bpp with 85 Hz (or more) and
- 3D
without having to install the driver from ATI? Is there a way?


I have, of course, tried to set the default depth, which works, but doesn't lower the resolution. Probably because today's graphics adapters are monsters --- even the cheapest come with 128 MBytes of RAM...

I had a running VESA fb configuraiton with a resolution of 1280x1024 at 24 bpp. I was just missing 3D. So I started to change a running system...

My problem:

After running xorgconfig I have a very basic configuration with a resolution of 640x480 --- a bit low, but that's ok, as xorgconfig doesn't claim to do anything beyond that.

So I tried xorgcfg, which gave me a working configuration, too. However, now I have 1920x1440 at 24 bpp --- impressive, but not what I want, and still no 3D. I tried to reduce the resolution, but that causes my root window to be moved beyond the screen limits.

Thanks in advance!

Did you try to do it without tools, by bare hands?

Max resolution\refresh rate is limited by the monitor horiz\vertical ranges you put in xorg.conf

Set it to the highest possible, then in KDE go
Control Center > Perihperals > Display (KDE3.3 here, it might be in different place in 3.2.3) and change the actual resolution/refresh rate to what ever you want.

I can help you lower your screen's resolution, but not with the 3D thing (not enough knowledge =)

Open the /etc/X11/xorg.conf from the console as root. Under the "Screen sections", place a "#" infront of any Display subsections that you don't want to use (not needed, but I do it for simplicity). Then, add "1280x1024" to the "modes" section, which falls under the display subsection that you want to use.

startx, and change the screen resolution from the menu.

Yes, I've tried it manually. Xorg server chooses 16bpp at 1920x1440, but I was able to get 24bpp by deleting the other sections. However, I don't know what to add, change or delete in order to get 3D and to choose a default resolution (like I did with a default depth).

The KDE menu entry you mention is there, but nothing happens, when I click it. Could have sworn that it worked, once...

Other suggestions...?

Thanks again,

gargamel

Thanks. I thought, I had put the # in front of the lines in the display subsections, but it seems I missed the modification in the modes section...

Thanks!

Now, hints on how to get 3D are still welcome... ;-)
