Re: r296548 breaks external DP and HDMI on HD4000

2016-04-26 Thread Ian FREISLICH 
Hi

Replying to myself...

The monitor works with in 1920x1080.  Any higher resolution and the
monitor displays rapidly changing random colours filled over the entire
screen.  I'm currently using r298115 with no improvement on the situation.

2016-03-19 Thread Ian FREISLICH 

Hi,

It was running 2560x1440. I'm not sure if the chip can do 4k although tho 
Xorg probe suggests it might. Maybe the rest of the interface electronics 
can't support the higher clock rate.  r296547 does correctly run the 
external monitor at 2560x1440.


Sadly the monitor is an international flight away from me for the 1.5 
months so I can't test anything else until I'm back.

On my Haswell laptop, the external DisplayPort doesn't work either. When
using Ultra HD, I get garbage. When using Full HD, the image is correct
for a few seconds, then the output connector is disabled (talking about
Panel status timeout in dmesg).

What resolution do you use with your monitor? If you're using Ultra HD,
could you please try Full HD?

r296548 breaks external DP and HDMI on HD4000

2016-03-14 Thread Ian FREISLICH 
Hi

With r296548 on the following hardware:

vgapci0@pci0:0:2:0: class=0x03 card=0x15171043 chip=0x01668086
rev=0x09 hdr=0x00
vendor = 'Intel Corporation'
device = '3rd Gen Core processor Graphics Controller'
class  = display
subclass   = VGA
cap 05[90] = MSI supports 1 message enabled with 1 message
cap 01[d0] = powerspec 2  supports D0 D3  current D0
cap 13[a4] = PCI Advanced Features: FLR TP

I get the following console messages when X starts and my external
monitor (Samsung U28E590) goes into epileptic fit attack mode.

[drm] Initialized i915 1.6.0 20080730 for drmn0 on minor 0

The good news is that I no longer need the following hack to turn on the
