Explanations for Clara - how to login to the system affected by this
bug.
(Re)boot your system, holding down the "Shift" key - the GRUB menu will appear.
In the GRUB menu select
"Advanced options for Ubuntu"
then
"Ubuntu, with Linux X.Y.Z-N-generic (recovery mode)"
(X.Y.Z-N is a kernel version number, choose any version, the latest one will be
fine).
In the "Recovery menu" choose
"root Drop to root shell prompt"
You get the root shell, but filesystem is mounted read-only. Remount it
read-write with the command like
mount -o remount,rw /
Now you can do what you like, for example,
vi /usr/share/X11/xorg.conf.d/91-noaccel.conf
and type the configuration lines I mentioned in my first post.
Instead of
Option "NoAccel"
you may also try
Driver "vesa"
- it is not as fast as native drivers, but supposed to work with most graphics
cards.

Title:
MACH64 video driver crashes with Mach 3D Rage Pro
Status in “xserver-xorg-video-mach64” package in Ubuntu:
Confirmed
Bug description:
It seems that xserver-xorg-video-mach64 is broken in Lubuntu 12.10.
After the upgrade from 12.04 to 12.10 MACH64 video driver crashes, causing
infinite loop at boot:
starting desktop manager, X server crash, restarting desktop manager, X
server crash, restarting desktop manager, X server crash, etc.
It is impossible even to switch to text console.
I found a workaround - booting in rescue mode, mounting filesystem read-write
and creating the file containing lines
------------------------------
Section "Device"
Identifier "Default device"
Option "NoAccel"
EndSection
------------------------------
in /usr/share/X11/xorg.conf.d stops the crashes of X server and allows to
boot desktop environment. But doing without video acceleration on a slow
machine is not a good thing.
I hope it will be possible to find the bug (in 12.04 this video driver worked
OK).
Some details which may be useful:
System:
CPU Pentium III 500MHz, RAM 512 MB
Video card:
01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI 3D
Rage Pro AGP 1X/2X (rev 5c)
OS:
Lubuntu 12.10 (upgraded from 12.04)
Package:
xserver-xorg-video-mach64 6.9.3-0ubuntu1
