recently i install a yellowdoglinux in a mac computer system...but it cant show the X server means GUI

Yo dude, YDL is nice.
Perhaps you can provide us with more information like YDL version, which Mac (iMac, G3, G4, G5).....

Cheers.

it is YDL 4.0 n mac power G4

with a geforce 2 graphic card
nvidia one

I have heard of YDL 4.0 having "no screens found" problem with Radeon cards only, and they have released a patch for XOrg in YDL 4.0 for that.

Can you please paste out the "/var/log/Xorg.0.log"?

I'll try to help.

Cheers.

i go change some configuration inside
then now i cant enter the linux already
sigh....

Hum, just cannot enter X only,
Still can enter runlevel 3 right?

n i configure the display file
then again it cant boot
it stop at the mount usb disk there
then it wont move
after config the file
then i use startx to test then it in a black screen
anyone pls help me

I don't get what you're trying to say.
Stop at mount usb disk, and since it won't move anymore, how did you use startx?
Duh...

I'm sure YDL 4 using Xorg anyway.
Paste out that Xorg.0.log...
Gee...

If that USB drive giving you so much problem..
Shut off the USB support in your BIOS first until you have done with the display problem.

Cheers.

ok
i think i manage to configure it
but after i change my refresh rate to 70 -140
it come to blank screen nothing come out?
how??

So, you mean, startx can display, the background is there, but there's no icon on the screen?
or, you mean, the background is not even there, and the screen is just black?
Are you using LCD?

I doubt that it's caused by refresh rate...
Usually we will start the refresh rate settings at the lowest possible first.
Horizontal or Vertical anyway, 70-140...
That's a bit high...
Default horizontal would be 30-54 and vertical would be 50-70
If the monitor can't display at default refresh, probably we need to do reduce the screen reso.

Cheers.

can see the screen blinking sometimes
so how??
i dunno wat actually the refresh rate
coz i install in a mac power pc G4

I suspect its the display driver. I just had the same problem, but Im using AMD Sempron on VIA chipsets. Are you sure using the correct/proper driver?

the workaround to my problem was that, I had to download another additional driver for my VIA chipsets and reboot, and it works!

Try looking in forums for Nvidia display drivers.
