Understood Chris, sometimes I need to read with more attention, English is not
my primary language.
Seems my display simply can't handle 24bit color depth, if I force a 16bit
color depth on xorg I can see great degrade of the render, clearly evident on
desktop wallpaper (see pic).
About the 24bit framebuffer, with or without UXA xdpyinfo and fbset shows the
same values.
effe@C400:~$ xdpyinfo | grep "of root"
depth of root window: 24 planes
effe@C400:~$ sudo fbset -i
mode "1024x768"
geometry 1024 768 1024 768 32
timings 0 0 0 0 0 0 0
accel true
rgba 8/16,8/8,8/0,0/0
endmode
Frame buffer device information:
Name : inteldrmfb
Address : 0xe0020000
Size : 3145728
Type : PACKED PIXELS
Visual : TRUECOLOR
XPanStep : 1
YPanStep : 1
YWrapStep : 0
LineLength : 4096
Accelerator : No
Probably I miss something here, anyway the important thing is I found a
workaround.
The only thing I regret is I can't use liveCD to test future versions on this
notebook as I can't set UXA via GRUB.
