In /etc/X11/XF86Config-4 I found:
Section "Screen"
Identifier "Screen0"
Device "Matrox Millennium G400"
Monitor "Monitor0"
DefaultDepth 24
Subsection "Display"
Depth 24
Modes "1024x768"
EndSubsection
and in /etc/X11/XF86Config:
# The svga server
Section "Screen"
Driver "svga"
Device "Matrox Millennium G400"
Monitor "Sampo AlphaScan 711"
DefaultColorDepth 32
Subsection "Display"
Depth 32
Modes "1024x768"
ViewPort 0 0
EndSubsection
EndSection
# The accel server
Section "Screen"
Driver "accel"
Device "Matrox Millennium G400"
Monitor "Sampo AlphaScan 711"
DefaultColorDepth 32
Subsection "Display"
Depth 32
Modes "1024x768"
ViewPort 0 0
EndSubsection
Why Depths are different? (24<->32)
Shall I change them?
Thanks
