Clean install will not change anything, because I installed ubuntu 12.10 (not upgraded), and still have this bug.
Seems to be a bug in Ubuntu (config). To permanently correct this, add this line at the top of /home/YOU/.profile : xset s 0 0 The file should look just like this : # ~/.profile: executed by the command interpreter for login shells. # This file is not read by bash(1), if ~/.bash_profile or ~/.bash_login # exists. # see /usr/share/doc/bash/examples/startup-files for examples. # the files are located in the bash-doc package. xset s 0 0 (and some other lines) -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1072531 Title: [regression] X11 screen blanking after 10 minutes with no UI to change it To manage notifications about this bug go to: https://bugs.launchpad.net/xorg-server/+bug/1072531/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
