Description Martin 2012-04-05 06:09:08 EDT
Description of problem:
Docking station DVI output doesn't work on Lenovo ThinkPad T520 with two GPUs while using only Intel HD3000. VGA port works fine.

Version-Release number of selected component (if applicable):
kernel 3.3.0-1.fc17.x86_64

How reproducible:

Steps to Reproduce:
0. Disable nVidia GPU in BIOS or force kernel to use i965 driver instead of nouveau.
1. Attach notebook to docking station.
2. Connect monitor to DVI port.
Actual results:
Monitor is not recognized on DVI.
VGA works fine.

Expected results:
i965 driver should support DVI port.

Additional info:
Using docking station ThinkPad Mini Doc Series 3.
T520 with 2 GPUs: Intel HD3000  and nVidia NVS 4200M. nVidia was disabled in BIOS.

Comment 1 Adam Jackson 2012-05-23 15:46:14 EDT
The "two GPUs" part is why this is tragic, and not going to work until we have proper Optimus support.  Digital outputs besides the laptop panel are simply not connected to the i915 chip on a machine like this.
Comment 2 Fedora End Of Life 2013-07-03 15:20:51 EDT
This message is a reminder that Fedora 17 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 17. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '17'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 17's end of life.

Bug Reporter:  Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 17 is end of life. If you 
would still like  to see this bug fixed and are able to reproduce it 
against a later version  of Fedora, you are encouraged  change the 
'version' to a later Fedora version prior to Fedora 17's end of life.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.
Comment 3 Fedora End Of Life 2013-07-31 13:42:35 EDT
Fedora 17 changed to end-of-life (EOL) status on 2013-07-30. Fedora 17 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
