Public bug reported: Binary package hint: xorg
I installed 10.04 and immediately upgraded to the latest linux-headers. When i attached my Samsung 2333sw monitor. I called Canonical support and was advised to chang this line in /etc/default/grub: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to include "radeon.modeset = 1" (and radeon.modeset=0), but that did not change anything. When the machine boots up, the laptop and LCD monitor are set to mirror each other (the default), both at 1024x768. When I enable an extended desktop, the LCD monitor goes blank when i click Apply. The display on the monitor shows a black box as follows: ------------------ Not Optimum Mode ------------------ (this message is coming from the monitor itself, not Ubuntu.) Any suggestions?
