no3d cheat parameter gets in an endless loop of starting X with Knoppix 8.2
I usually use knoppix with the no3d boot parameter, like "knoppix64 no3d noscreensaver" but I've noticed with 8.2 it will go into a endless cycle of trying to start X, failing and trying again.
If I don't use no3d, everything is fine.
I thought no3d would just disable compiz.

Same observation here on laptop with Intel Haswell and desktop with nvidia GT218.
Funny observation: on VirtualBox virtual machine with 16 MB video memory and no 3D acceleration, booting with cmdline "knoppix64 keyboard=dk" works fine, starting X without compiz. It seems that if Knoppix 8.2 is allowed to detect that the machine has too little graphics resources to run compiz, it starts X with window manager openbox-lxde just fine. However, when I boot the same VM with cmdline "knoppix64 keyboard=dk no3d" it fails to start X and enters the endless cycle of failing.

no3d changes "something" more ...
fortunately 8.3 has ( undocumented ? ) nocompiz bootparameter
it gets parsed by /etc/X11/Xsession.d/45knoppix
however the "no3d" bug making x unstartable should be investigated ...
the error message with no3d is:
[ 40.424] vesa: Ignoring device with a bound kernel driver
Code:
[ 40.404] (II) LoadModule: "vesa"
[ 40.404] (II) Loading /usr/lib/xorg/modules/drivers/vesa_drv.so

[ 40.424] (II) UnloadModule: "vesa"
[ 40.424] (EE) Device(s) detected, but none match those in the config file.
the difference in xorg.conf is as follows:
Code:
knoppix@Microknoppix:~$ diff xorg.conf-mit-nocompiz xorg.conf-mit-no3d
66c66
< Option "Composite" "Enable"
---
> Option "Composite" "Disable"
99c99,100
< # Driver (chipset) autodetect
---
> # Specified driver (chipset)
> Driver "vesa"
who knows why the kernel already allocated the device so vesa cancels itself ?
why at all nod3 writes vesa in the config ?
the followin scripts are also part of configuring x11 :
/sbin/hwsetup
/sbin/mkxorgconfig
