Hey guys, I'm stuck on 1024x768 resolution. I'm using an X1650pro.

I'll keep researching & updating

Thanks all,
Pete

here's a quick fix... but research it to get the full output from your video card.

Open Terminal and type

<b>sudo nano /Library/Preferences/SystemConfiguration/com.apple.Boot.plist</b>

Use the arrow keys to move the cursor. Ctrl+O to save (and then press Enter to save) then rename the <b>*.save</b> file that was created to the original after you've deleted your <b>com.apple.Boot.plist</b> file.

To automatically use a certain graphics mode
<b><key>Graphics Mode</key>
<string>1280x1024x32@85</string>
Note:</b> If your video card is using VESA 2.0 drivers, leave out the '<b>@85</b>' part as it only works on VESA 3.0 will cause the system to reset before getting anywhere. This '<b>@85</b>' is the Hz refresh rate.

Remember, this is only a quick fix. find the correct kext for your card if you want the full output.

@XX was never working for me, even on VESA 3.0

katana or callisto, is the bets way to change the resolution on ati cards that don't have good drivers

thanks a lot people, I'm anxious to try these new methods, but I'm stuck right now :(

Before anyone posted replies I went ahead and installed Callisto. I followed the instructions carefully but when I rebooted (oh no!) kernel panic!
I tried in booting in -s to delete the callisto kexts files but mount -uw wouldn't let me access the filesystem "read-only file system!"

Can anyone help me?
thanks

Did you try /sbin/mount -uw / or just mount -uw?

Ahh thank you so much DoiX ! ;)

Okay I tried that boot.plist method
I put in 1680x1050x32 but when I boot it's at 1400x1050 ! (It looked a bit stretched and in preferences it said 1400)

Any ideas?
thanks again :)

Widescreen? Try 1440x900x32

Thanks for the suggestion, naquaada

Unfortunately when I tried that it locked me on 1152x864

I don't really have an idea what's going on. is it somehow locked on an aspect ratio?

thanks again,
peter

seems that standard VESA modes only support 4:3 monitors :(

there's no way around that?

I do have drivers... i'm using (what's it called?) QE/CI, with the semi-transparent menu bar.

I don't really know what VESA is but I don't think I'm using it. is VESA the default/standard graphics displaying format?

VESA is a standard for various formats, graphics are a part of it. Standard VESA graphic modes are f.e. 640x480, 800x600, 1024x768 and so on. On my Amiga I created an graphics mode with 420x316 pixels, this is surely not a VESA graphic mode ;)

This is really strange...
At the beginning I installed Firewalk's guide and I came to this problem, I somehow managed to break my system and after a reformat I followed the guide again except now I can select any resolution and also there's no mouse tearing (!?)

I did exactly the same thing !
Anyway, thanks for all your help guys, maybe I didn't follow the guide well enough :)
