Géza Búza, the next step is to fully commit bisect from Lucid to
Precise, in order to identify the offending commit. Could you please do
this following https://wiki.ubuntu.com/Kernel/KernelBisection ?

Title:
1002:9591 [Lenovo ThinkPad T500] External monitor on display port has
no sync with radeon driver
Status in The Linux Kernel:
Confirmed
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
When I turn on the external monitor, it displays an error message:
"The current input timing is not supported by the monitor display.
Please change your input timing to 1920x1080@60Hz or any other monitor listed timing as per the monitor specifications."
WORKAROUND: Installing fglrx-legacy 8.97.100.7 on Ubuntu 13.04 solves
the problem.
The GNOME display settings dialog shows exactly this recommended setting as current.
I even tried to set it up using xrand with:
$ xrandr --output DisplayPort-0 --auto -s 24/1920x1080 -r 60
$ xrandr -q
