[Bug 1559308] Re: Plugging HDMI screen in causes system hang

@Jonathan: I was on 15.10. :| The problem with 15.10 is the trackpad doesn't work due to a bug in the i2c driver (drivers/i2c/busses/i2c-designware-platdrv.c) for kernels < 4.5. When I upgraded my kernel to version 4.5 I started getting this same external monitor issue. Since 16.04 is using a

[Bug 1559308] Re: Plugging HDMI screen in causes system hang

Ok, it seems as Intel has just 'forgotten' to make their newest drivers available. That's why they are not included in 16.04. There is a German article on that available here: http://www.heise.de/newsticker/meldung/Linux-Intels-neue-Iris-Grafik- Treiber-Support-in-Sicht-3193993.html (translation:

Yes, I can also confirm this problem with a Lenovo Thinkpad T460s (using a docking station as well as without one). I am also using the Mesa DRI Intel(R) HD Graphics 520 (Skylake GT2) (0x1916) GPU running on the i915_bpo driver. Interestingly enough, when I use the docking station and connect

[Bug 1559308] Re: Plugging HDMI screen in causes system hang

Same problem on my laptop, started right after upgrade from 15.10 to 16.04. Happens right after I plug external monitor to to HDMI socket, system freezes and not responding to any actions from keyboard and touchpad. I'm using Intel® HD Graphics 520. -- You received this bug notification because

Same problem here, also right when I upgraded from 15.10 to 16.04. It only happens with the external monitor, and only after logging into gnome. I'm on a Asus zenbook UX303U with NVIDIA GeForce 940M. I need to plug in many different external monitors and projectors for presentations, so having it

I reported earlier that the crash only happens for me when I move the mouse pointer from my external monitor to the laptop primary display. I just reproduced again when moving the mouse pointer the other way: It was fine with the mouse cursor on the laptop primary display for a while (2 minutes,

@Scott: This bug only started happening for me when I upgraded from 15.10 to 16.04. You could try installing 15.10 and maybe it will be fine for you, and you can use that until a fix appears. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to

[Bug 1559308] Re: Plugging HDMI screen in causes system hang

I have a Asus Zenbook UX305CA-EHM1 M3-6Y30. It's a pretty sweetly designed machine and Ubuntu looks and works awesome on it EXCEPT for this external monitor issue. I've got the Intel HD Graphics 515 using the i915_bpo driver and a micro HDMI display port. I've got a few days left to return this

Mine has a usb3.1 with an adaptor providing another HDMI and a VGA port. They all work the same, ie hardly!, so if say don't rush out and spend cash! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu.

[Bug 1559308] Re: Plugging HDMI screen in causes system hang

It crosses my mind that as well as the HDMI output, my laptop also has a mini display port. Does anyone have a feel for whether it's worth buying an mini display port adaptor or cable to test whether that behaves the same? -- You received this bug notification because you are a member of Ubuntu

If I have an external monitor, then I get a crash when when I move my mouse cursor on to the primary (laptop) display. I get the same traceback in my syslog as that posted above by @shinyblue. My graphics card is the integrated Intel HD Graphics 520 Mobile, i5 6200U, using driver i915_bpo. My
