View Full Version : [ubuntu] Mouse drags patch while scrolling.

January 1st, 2009, 07:04 PM
After I installed Ubuntu8.10, updated and modified my xorg.conf to allow my video driver I notice that when I click my left mouse button and then use the scroll button the pointer drags a square of the screen from where I clicked to where I scroll to. I don't think that it is my xorg.conf, but has something to do with the updates.

I had a lot of errors when updating, mostly to do with broken packages and dependencies. I fixed the broken packages and uninstalled and reinstalled the packages with dependency problems until no more error messages appeared. I think that the major culprit was the package ubuntu desktop and its dependencies.

Here is my xorg.conf:

# xorg.conf after running sudo nvidia-xconf with modifications:
# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig: version 1.0 (buildmeister@builder57) Mon Oct 27 14:37:20 PST 2008

# values from the debconf database.

# (Type "man xorg.conf" at the shell prompt.)

I don't remember much about all the packages involved; that was a pretty chaotic time trying to fix everything, and my mind is getting a little old.

Any ideas on how I can fix this?

Ha! The problem was xorg.conf. I changed from the software cursor to a hardware cousor:

Option "HWCursor"

and no more scrolled patches.
