Arch Linux

Attached the dmesg output after connecting and disconnect the monitor.

Hi,

Please note that he same issue is present in other distribution: (FC-23: https://bugzilla.redhat.com/show_bug.cgi?id=1265606).

I'm having the exact same issue with my external monitors connected to the docking station. Activating any of my three connected monitors with xrandr will lead to this. This only occurs while I'm on the 4.2.1-1 kernel from the arch repo. Downgrading the kernel seems to fix it for the time beeing.

Hi,
Please note that this issue happened only after the update to the new kernel version 4.2.1.

Hi,
I tried the linux 4.2.2-1 version and the external screen is now displayed.
But I got the following logs from dmesg:

Hey Hatem,

I don't think this is the same bug we're seeing.

Nevertheless, the 4.2 i915 driver does seemed stuffed.

Sorry.

My comment was based on what you pasted, not your bug.log

I'm having the same issue with kernel 4.2.1-1.

Are you able to use the external monitor if you switch to virtual consoles and switch back to X? i.e pressing Ctrl+Alt+F1 should bring the console on both the primary and external monitor. If it doesn't happen on the first try, try switching to another virtual console (Ctrl+Alt+F2). Once the console shows up, switch back to X (Ctrl+Alt+F7). This currently works for me.

This bug is similar to https://bugs.freedesktop.org/show_bug.cgi?id=89589 except that this bug is also triggered when X is locked.

With kernel 4.2.2-1 my external monitor is working again. However, i still have this error:

[drm:check_crtc_state [i915]] *ERROR* mismatch in ips_enabled (expected 1, found 0)

kernel 4.2.2-1 fixed the problem for me.

The 4.2.2-1 kernel fixed the problem for me too. No additional error messages or warning, everything is workthing smoothly as ever.

Hello,
I wanted to ask, if the topic could be reopened. The update of one these packages results in the same problems (probably xf86-video-intel)
* wayland
* mesa
* xf86-video-intel
* mesa-libgl

The new package (I believe xf86-video-intel 1:2.99.917+478+gdf72bc5-2) fixed it. Thanks a lot !

The bug ist back again:

Nothing is displayed on my second monitor. Also it is possible to drag something into it. Opening gnome display settings results in a white error screen, where i have to relogin. This results into a complete freeze of the system.

Here is an extract from my log:

A short update on this matter.
At the moment it works with a second monitor, but highly instable.

At boot everything works, but releasing the laptop from the docking station or putting it back in, results in problems.
The latter one results constantly in gnome crashing with a white screen and the message that something went wrong and I have to login again (Relogin results in a freeze of the OS).
Also a constantly message that I still have in my journal log is:
> Nov 05 10:08:44 <hostname> kernel: [drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!

Also opening the Gnome Desktop setting from the Settings menu results in a black screen for a short while.

Furthermore sometimes the screen just stop working and even after a reboot the matter persists. Just after several reboots it works again. But I can't reproduce what causes this. (I think it is related to pacman, e.g. when I update some libraries through it)

I hope it helps.
Thanks for looking into this!
