Against every recommendation I have
apt-get remove python in Ubuntu 10.10 (build 2.6.24-29-server x86_64) and
apt-get install python2.7
Some built-in software with python2.6 dependencies (like firefox, other minor stuff) was fixed just by apt-get reinstalling or reinstalling from source and the system was stable for one day until I rebooted.
Upon booting I got the message "ubuntu is running in low-graphics mode" I have an NVIDIA Quadro NVS 295 256 running on a HP Z600 Workstation so I sudoed:
apt-get --purged nvidia* apt-get --purged xserver apt-get install linux-headers-generic apt-get install nvidia-* apt-get install xserver-xorg dpkg-reconfigure xserver-xorg nvidia-xconfig
upon rebooting i get the same "ubuntu is running in low-graphics mode" if I decide to tell the boot menu to restart X, the Ubuntu 10.10 "load screen" shows up and does not do anything for hours.
If I "X" the screen remains black for hours; ctrl-c shows that /etc/X11/xorg.conf did not produce any errors just a warning "Type "ONE_LEVEL"...". /var/log/Xorg.0.log issues the following warnings (no errors) (WW) AllowEmptyInput is on (WW) NVIDIA(0): UBB is incompatible
If I "startX" I get /usr/bin/python: can't find '__main__.py"' in '/usr/share/command-not-found' Before re-installing xserver-xorg however "startX" ran, just by changing the resolution of the tty1 console.
