Thread: Lenovo Thinkpad W520 Docking Station troubles

-

hey guys, i'm using ubuntu 11 partition on lenovo w520 thinkpad.

default os windows 7, , when boot using windows 7, computer recognizes docking station when loading screen. before monitor keeps flashing on , off saying it's trying connect.

when try boot using ubuntu partition, laptop doesn't recognize monitor.
this monitor in case helps.

laptop works fine when run without docking station in either windows 7 or ubuntu.

i'll take , suggestions!

hi evonus.

suspect trouble not based in docking station, in graphics card.

have lenovo w520 nvidia quadro 1000m graphics card. card uses optimus technology switch between built-in intel graphics , more powerful (but battery-draining) accelerated nvidia chip. unfortunately optimus, , nvidia whole, famously unsupportive of non-microsoft os.

may try opening bios , disabling nvidia optimus there, seems built-in intel graphics weak run external monitors. might try using displayport cable (or dp-to-dvi) connect not via docking station on laptop directly.

luck , let know if have success - i'm dying windows off of machine haven't gotten dual external monitor support working yet. fingers crossed...
