bug:  
when I start a SDL-FULLSCREEN at any resolution the system shows a BIG  
window (with the same theme of my wm) that covers the surface

system: XFree 3.3.6 (SVGA)  
sawmill version 0.24  
RH 6.2

thanks michele

This is SDL’s way of giving you a fullscreen window even though you don’t  
have the requested video mode configured. You need to add the desired modes  
to your X configuration.

See ya!

I HAVE the video mode configured.  
the window is black and empty and covers the screen. some times I get  
the fullscreen without problems.

Speaking of modes, here are modelines for some cute modes that may  
come in handy if you need to run very low resolutions on very big  
and/or sharp CRT monitors:

—8\<----------------------------------------------------------------------

# 320x240 @ 100 Hz, 53.01 kHz hsync

Modeline “320x240” 22.9 320 336 384 432 240 244 247 265 DoubleScan

# 400x300 @ 100 Hz, 64.02 kHz hsync

Modeline “400x300” 34.8 400 432 464 544 300 302 305 320 DoubleScan

# 640x480 @ 100 Hz, 107.16 kHz hsync

Modeline “640x480” 88.62 640 656 720 848 480 488 492 524 DoubleScan

# 800x600 @ 100 Hz, 64.02 kHz hsync

Modeline “800x600” 139 800 864 928 1088 600 604 610 640 DoubleScan

----------------------------------------------------------------------\>8—

NOTE: These use video frequencies normally used for 640x480 through  
1600x1200 @ 100 Hz, so the higher ones won’t work on the  
average 17" or smaller monitor. OTOH, you probably don’t need  
double scan above 400x300 on those anyway.
