I'd consider the removal of that displayconfig script a fix in and of itself so you might consider marking it "fixed" rather than "won't fix". -- guidance-backends overwrites xorg.conf without confirmation or notification, if video card has changed since last boot https://bugs.launchpad.net/bugs/257809 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Displayconfig is unmaintained and nonexistent in Intrepid, so this won't be fixed. Although in your case it probably is fixed, since displayconfig is no longer around to muck up your xorg.conf. ;-) ** Changed in: kde-guidance (Ubuntu) Status: New => Won't Fix -- guidance-backends overwrites xorg.conf without confirmation or notification, if video card has changed since last boot https://bugs.launchpad.net/bugs/257809 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 257809] Re: guidance-backends overwrites xorg.conf without confirmation or notification, if video card has changed since last boot
** Description changed:
Binary package hint: kde-guidance
Some laptops allow the user to choose between an integrated GPU (for
power savings) and a discrete GPU (for performance). One of my friends
has such a laptop; I've set it up with a customized xorg.conf file,
tweaked with Device entries for both Intel and NVIDIA drivers, to make
the GPU switch as "transparent" as possible. On several occasions, I've
also booted my own system (with video and touchpad tweaks) in a USB
enclosure, connected to other computers. Under both situations, I've
noticed the following behavior:
Upon booting with a different GPUs or computers, I was unpleasantly
surprised when I Xorg started without any of my settings... and
sometimes dropped back to failsafe mode. I noticed the losing settings
when I ended up randomly, unexpectedly clicking things, due to Xorg
having lost my "disable tapping" setting.
- I took a look in xorg.conf, and noted that something had trampled upon it,
without confirmation, and without notification. Most of my custom settings
were gone, and all of the whitespace that makes my comments organized were
entirely gone.
+ I took a look in xorg.conf, and noted that something had trampled upon it,
without confirmation, and without notification. Most of my custom settings
were gone, and all of the whitespace that keeps my comments organized was
entirely gone.
Here's my xorg.conf file, for reference; it has entries to make it work on
multiple hardware configurations:
www.csc.calpoly.edu/~dgoyette/xorg.conf
I grepped around in various places to figure out what was overwriting
xorg.conf, and identified the following script as the offender:
guidance-backends:
/usr/share/python-support/guidance-backends/displayconfig-hwprobe.py
When I dpkg-divert i... so I dpkg-diverted it out of place, and have hence
had no issues.
I understand the need for things to "just work" upon video card swap,
but this script seems 'evil' for not respecting any of my
settings... and it didn't even make a working xorg.conf file! I
booted with the Intel GPU, and the file it generated had only my
NVIDIA(!) section, with all whitespace removed, and with the Synaptics
section gone. If it helps, I can let the script run again, and add the
created xorg.conf file to this bug report.
I believe this script should either be entirely removed, or should either
leave the file alone, or prompt before overwriting it, if any of the following
conditions are true:
1. If the xorg.conf file already has a defined section for the current
device (as it should ideally work without changing).
2. If the xorg.conf file is heavily customized ("heavily" will need some
definition), as advanced tweaks are there for a reason!
The mechanics of this prompting would need some work, though... perhaps
use the new usplash prompting interface? If that's not feasible, please
make it leave xorg.conf alone ... or at the very least, generate a
working configuration, and then TELL the user that the xorg
configuration file has been automatically regenerated.
+ Additional note: why is this (kde-guidance) installed on Ubuntu (non-
+ KDE) systems? If it's not just for KDE, then "kde-guidance" seems like
+ a misnomer.

The offending section of the python file:
if previous_hardware is not None and previous_hardware!=hardware_config:
# Run dpkg and configure the new hardware.
syslog.syslog(syslog.LOG_INFO, "Graphics card hardware has changed.
Reconfiguring xorg.conf using 'dpkg-reconfigure xserver-xorg'.")
cmd = ['dpkg-reconfigure','xserver-xorg']
environ = os.environ.copy()
environ['DEBIAN_FRONTEND'] = 'noninteractive'
#os.spawnvpe(os.P_WAIT, 'dpkg-reconfigure', cmd, environ)
result = ExecWithCapture('/usr/sbin/dpkg-reconfigure', cmd, 0, '/',
0,1, -1, environ)
for line in result.split('\n'):
syslog.syslog(syslog.LOG_INFO,"dpkg-reconfigure:"+line)
