@Abhijit: I don't think the xorg.conf that gpu-manager generates is causing your problem (I don't see anything wrong in the X log) but let's see what happens when the gpu-manager is disabled. Please follow these steps:
1) sudo nano -w /etc/default/grub 2) Add "nogpumanager" in the following line (within the quotation marks) e.g. if you have this line: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" it should look like this: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nogpumanager" 3) Press CTRL+X to save and exit 4) sudo update-grub 5) Reboot 6) Make sure that the following command returns true: grep nogpumanager /proc/cmdline && echo true || echo false 7) If it returns true, regenerate the xorg.conf sudo aticonfig --adapter=all --initial 8) Reboot and see if it all works (attach your /var/log/Xorg.0.log and /etc/X11/xorg.conf) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1310489 Title: xorg.conf overwritten by booting system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-drivers-common/+bug/1310489/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
