--- Comment #8 from Thomas <tg42 at gmx.de> ---
In Bug #53307 i saw some other information provided that i hope to be helpful:

root at amilo:/home/thomas# lspci -v -s 1:0
01:00.0 VGA compatible controller: VIA Technologies, Inc. CN700/P4M800
Pro/P4M800 CE/VN800 Graphics [S3 UniChrome Pro] (rev 01) (prog-if 00 [VGA
controller])
    Subsystem: Fujitsu Technology Solutions Device 10cd
    Flags: bus master, 66MHz, medium devsel, latency 64, IRQ 10
    Memory at f0000000 (32-bit, prefetchable) [size=64M]
    Memory at d1000000 (32-bit, non-prefetchable) [size=16M]
    Expansion ROM at <unassigned> [disabled]

root at amilo:~$ dmesg | grep -iE '(agp|drm)'
Linux agpgart interface v0.103

agpgart-via 0000:00:00.0: putting AGP V2 device into 4x mode
pci 0000:01:00.0: putting AGP V2 device into 4x mode

And this:

root at amilo:~$ grep '(EE)' /var/log/Xorg.0.log
    (WW) warning, (EE) error, (NI) not implemented, (??) unknown.
[     9.999] (EE) AIGLX error: dlopen of
/usr/lib/i386-linux-gnu/dri/unichrome_dri.so failed
(/usr/lib/i386-linux-gnu/dri/unichrome_dri.so: cannot open shared object file:
No such file or directory)
[     9.999] (EE) AIGLX: reverting to software rendering
root at amilo:~$ locate unichrome
/usr/lib/i386-linux-gnu/directfb-1.2-9/gfxdrivers/libdirectfb_unichrome.so

Should i use unichrome_dri?  (This would probably affect performance only, but
not mere working or not, i guess.)  It doesn't seem to be offered by the ubuntu
repository, anyway.
