RADEON 7500 works but only in live mode(very strange)

alright heres my situation. ive been using knoppix hd install for some time and love it. however like ALL distros, my radeon 7500 would not get detected and i would get horrible 3d performance. today i acciedentally had my knoppix cd in the tray and it booted. while it was booting i paid careful attention to the text and noticed something similar to this:

AGP Bridge Detected
video = Radeon QW(75000) using x(radeon) server.

so i let it boot into kde and tried a 3d game(chromium) and was surpassed to see that i was getting 3d accelerted graphics.

Why did it detect my gpu while im using live mode and not after after i do an hdinstall???

plez help

sudo xedit /etc/X11/XF86Config-4

Look for the section that looks something like this:

Code:

---

# The following line is auto-generated by KNOPPIX mkxf86config
        Driver      "vesa"
        VendorName  "All"
        BoardName  "All"
#      BusID      "PCI:1:0:0"

---

Make sure the driver is either ati or radeon like so:

Driver "ati"

or

Driver "radeon"

My 7200 uses the ati.

After that, do this:

glxinfo

It should have a line that looks like this:

Code:

---

direct rendering: Yes

---

That should do it.

hmmm its says it doesent

heres my glxinfo

So are you using the ati or radeon driver in XF86Config-4?

If so - did you restart the xserver before running glxinfo?

i tried radeon, ati, and vesa. all didnt work(i restarted and checked)



im not sure if this helps but im using live mode and heres my new

glxinfo just tells you info about direct rendering and such. What you need to compare are your XF86Config-4 files. Have a look at the "booted from cd" XF86Config-4 and see what driver it's using.

both config files are the same. but i did notice something else. i did a search on dri and found that
/dev/dri/card0 is 0b when its around 800b its live mode
/proc/dri has a size of ob but in the live mode its 12.5mb

im not sure if that helps but might as well post it

lol um heres my lspci -v for the radeon. lol im just posting anything relavent
