Description anonymo29 2012-03-05 03:49:50 UTC
Description of problem:
I have a Dell XPS laptop, which comes with a mini DisplayPort powered by an integrated Intel graphics card. Any external monitor connected to the mini DisplayPort reports that there is no sync. I have tried both Fedora 15 and 16 to no avail.

Note that this issue is different from the nVidia issues on the same laptop.


Version-Release number of selected component (if applicable):
Output of lspci for related graphics card:

00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) (prog-if 00 [VGA controller])
        Subsystem: Dell Device 04b6
        Flags: bus master, fast devsel, latency 0, IRQ 52
        Memory at f1400000 (64-bit, non-prefetchable) [size=4M]
        Memory at e0000000 (64-bit, prefetchable) [size=256M]
        I/O ports at 4000 [size=64]
        Expansion ROM at <unassigned> [disabled]
        Capabilities: <access denied>
        Kernel driver in use: i915
        Kernel modules: i915
 

How reproducible:
Always


Steps to Reproduce:
1.  Connect any external monitor to a Dell XPS laptop with similar Intel graphics card (recent Dell XPS 17, 15, 15z or 14z) through the mini DisplayPort. Use a suitable mini DisplayPort to HDMI or DVI adapter.

2.  Power on the external monitor, then the laptop.

3.  Enable dual display from the display dialog box of system settings.
  
Actual results:
The external monitor shows the Fedora flash screen during power on. Once the system is fully started, the external monitor reports no sync. Only the laptop screen has a working display.

In system settings, the external monitor is recognised. I can drag a visible window off the laptop into an invisible display to the right. Such windows will then no longer be visible. But a screenshot will show the invisible display, along with any window that was dragged into it.


Expected results:
The external monitor should be fully functional with a visible display.

The issue has been marked resolved in the upstream.

kernel-utils isn't a valid component for fedora, reassigning over to kernel.
