Public bug reported:
Binary package hint: xorg
Switching from running xserver to a virtual terminal via CTRL+ALT+Fxx
and back causes the system to freeze. When switching back to X a black
screen appears. The computer does not react to any keys or acpi buttons
and has to be reset. This problem also appears when DRI is turned off or
when the vesa driver is used instead of the ATI one. With the vesa
driver the system crashes not so often but it still happens after a
couple of terminal switches. Instead of a black screen, the screen fades
gradually to white when the system freezes and the vesa driver is used.
Changing the kernel to 2.6.32 or using the newest drivers from xorg
edgers could not solve the problem. This problem did not appear before
with Ubuntu 9.04.
