Hi,
After trying two different machines I'm beginning to feel like Skylake is completely unusable with multiple monitors connected. Is this a known limitation? Am I the only one experiencing this?
First I tested on laptop Dell XPS 15 9550 with QHD display. Seems to work fine with internal panel, though I haven't used it extensively. Immediately or sometimes within a minute or two when I connect an external monitor using HDMI the system freezes completely (ping reply stops). This is with updated Fedora 23 with kernel from drm-intel-nigthly tested several
times during the last two months. I've reported this here:
https://bugs.freedesktop.org/show_bug.cgi?id=94625 with more details.
Now I've also got access to a Dell Precision Tower 3620. Being a tower, this of course has no internal panel. Connecting one external monitor seems to work, but again I've not used it extensively. The second I connect a second monitor it freezes completely. Booting with two monitors connected also doesn't work. This is with updated Fedora 23 and distribution kernel 4.4.6-300 (waiting for download/build of drm-intel-nigthly to finish). CPU is i7-6700 stepping 3 microcode 0x74.
What else to do or test?
Both systems are using latest available BIOS from Dell.
Regards,
Oskar
