The default color depth was chosen when you setup X using Xconfigurator, XF86Setup, or whatever. Assuming you have sufficient video memory for your screen size, use startx -- -bpp 24 to have Xwindow start with "24 bit" color. ** Color depth cannot be changed without exiting to the command line. ** 2. The desktop is too big about 4 times than my screen of monitor. Why? I have to move my mouse all around in order to find some thing on the screen. This is dependent on screen resolution, e.g. 640x480, or 800x600, or 1024x768(?), or You chose the allowable resolutions when you setup X using Xconfigurator, XF86Setup, or The highest resolution is the only one that will show the full screen. That is, if I setup X so that at 16bpp I can have 800x600 or 640x480, I'll have to pan around (using the pointer/mouse as you describe), while 800x600 will show the "entire desktop." The resolution that comes up is the one listed first in /etc/X11/Xconfig (I think that's the file Mandrake looks to when you run startx). You can view the file by running less /etc/X11/Xconfig from the ocmmand line. Here's what a part of mine looks like. -=-=- Section "Screen" Driver "SVGA" Device "My Video Card" Monitor "My Monitor" DefaultColorDepth 16 BlankTime 0 SuspendTime 0 OffTime 0 SubSection "Display" Depth8 Modes"1024x768" "800x600" Virtual 1024 768 ViewPort 0 0 EndSubSection SubSection "Display" Depth15 Modes"1024x768" "800x600" EndSubSection -=-=- The first resolution listed (as Modes) in the -- SubSection "Display" -- is the resolution that you see when Xwindow starts. If there are other resolutions listed on the line they can be achieved using the Ctl+Alt++(numberpad) that you mentioned. Thanks! John l.yn Hope that helps. Gerry

To change resolution (pixels x pixels), use Ctrl-Alt-NumPad + and Ctrl-Alt-NumPad - To change color depth, you'll have to exit X and add a flag to your startx command. Something like this should work: startx -- -bpp 16 or startx -- -bpp 24 2. The desktop is too big about 4 times than my screen of monitor. Why?

If nothing changes try running XF86Setup as root, and select the appropriate resolutions. Bela (please, if you are a dreamer, check out our website: http://members.xoom.com/_XOOM/belantos/index.html) Hi, John, crtl-alt-+ will change the screen resolution, not the color depth. If you want to change from 16-bit color to 24-bit color, exit X, and then restart X with 'startx -- -bpp 24' for 24-bit color. If your desktop is too big for your screen, set the virtual screen in /etc/X11/XF86Config. For example, if you want a 1024x768 screen resolution in 24-bit color as your default, add the line 'virtual 1024 768' in the 24-bit stanza of /etc/X11/XF86Config. OK, good luck, Hidong

1. I want to change the resolution of X-windows from 16 color to 24 bit color.Help say that using 'alt'-'ctrl'-'+', but it doesnt work. startx -- -bpp 24 ( you can add this line to your xf86config file to have it start x in 24 bit as default, but I prefer just creating an alias for the different color depths that I use. Being a new user, I still mess things up often, and this method leaves me some options just in case.) I don't know why the 'alt'-'ctrl'-'+' method doesn't work. Doesn't work on my machine as well? 2. The desktop is too big about 4 times than my screen of monitor. Why? I have to move my mouse all around in order to find some thing on the screen. I'm using an i740 based card with the XBF server, so I'm not sure if this will work in your case, but when running xf86config, it asks if you would like a desktop larger than your screen. Selecting no for each resolution/color depth fixed the problem for me. Hope that helps. Ben
