When we use cirrus logic video cards and rdesktop1.5 receive de following error trying 800x600
 
cirrus(0): not using default mode "800x600" (Insufficient memory given virtual size)
cirrus(0): Virtual Size "640x480" (pitch 640)
cirrus(0): Default mode "640x480": 25.2 mhz, 31.5 khz, 60.0 hz
cirrus(0): Modeline "640x480" 25.20 640 656 752 800 480 490 492 525 -hsync -vsync
cirrus(0): dpi set to (75, 75)
 
If we use ICA protocol insted rdesktop works fine with 800x600. Same video card cirrus logic!!!!
 
Any ideas?
