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.

Title:
[830 v3.7 regression] Video goes blank and system hangs (using an old
kernel fix it)
Status in “xserver-xorg-video-intel” package in Ubuntu:
Confirmed
Bug description:
I'm on a very old Dell C400 P3 866 with 768mb ram which still works
rock solid. I've upgraded this system from Lubuntu 12.10 to 13.04 but
with every kernel above V3.6.11 (took from mainline ubuntu) system
hangs randomly.
I tried to install Intel video drivers from
https://01.org/linuxgraphics/ (Intel(R) Linux* Graphics Installer
version 1.0.1 for Ubuntu* 13.04 (32-bit)) but this did not solve the
problem. I'm not sure if is driver or kernel related since on the last
release change the drivers curiously works using kernel V3.9 but
before revert to this release I would like to help to find a solution.
