T60-1952 w/ Advanced dock + Radeon 5450HD

[ericvb69]

Hi,

I've been using a T60 (1952AT7/1952AT7, BIOS 79ETE7WW (2.27 ) 03/21/2011) running Linux/Ubuntu as my main computer for the last 5 years. A couple of weeks ago, I purchased a second hand Advanced Dock (2503) because it lets me connect a 2d and 3d monitors to the CPU.

I also bought a fanless Radeon HD5450 and plugged it in the pci-express slot of the dock.

I'm having problems to init the radeon card correctly:

Has anyone had any success with this configuration?
