Please try this patch: http://mid.gmane.org/1422373429-10137-1-git-send-email-simon.farnsworth@onelan.co.uk Created attachment 113146 [details] dmesg - with patch "drm/dp: Use large transactions for I2C over AUX" Thanks for a prompt reply! I applied that patch on top of kernel 3.18.5, tried on that laptop - no effect. Same behaviour, same errors. dmesg is attached. In case other logs are needed, they are here: http://hw.rosalinux.ru/index.php?probe=17d5745ffe I built vanilla kernel 4.0-rc3 on that system - the problem is still there. The logs (dmesg) before and after I tried to switch to the external monitor will be attached below. Created attachment 114322 [details]

We've fixed plenty of issues with DP aux/i2c-over-aux lately, presuming we've fixed this one too. Please reopen if the problem persists with latest kernels. (In reply to Jani Nikula from comment #9) > We've fixed plenty of issues with DP aux/i2c-over-aux lately, presuming > we've fixed this one too. Please reopen if the problem persists with latest > kernels. Unfortunately, the problem is still there even with kernel 4.3 vanilla. After the system boots, the external monitor works, I can drag windows to it, etc. But when I try to make it the main output, the screen flickers a bit and the external monitor can no longer be used. I will attach the new logs below. "too many retries, giving up" message is output several times there. Additionally, when I try to switch to the external monitor, there is the following warning, not sure if it is related: ------------------------- [drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in has_drrs (expected 1, found 0) ------------[ cut here ]------------ WARNING: CPU: 2 PID: 6939 at /home/alina/distrib/kernel/linux-4.3/drivers/gpu/drm/i915/intel_display.c:12700 intel_atomic_commit+0xd65/0x1350 [i915]() pipe state doesn't match!

Similar bug report on Ubuntu bug tracker: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1300914?comments=all (In reply to Andre Rummler from comment #14) > Similar bug report on Ubuntu bug tracker: > > https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1300914?comments=all By the way, the "workaround" mentioned in that bug report works for me. I mean, I've recently bought a DisplayPort-to-VGA adapter and connected the external display to the laptop via DisplayPort with it. Seems to work OK so far on kernel 4.1.13. |
