Sorry for the delay, I tried: linux-image-4.4.0-83-generic doesn't work linux-image-4.8.0-040800-generic doesn't work linux-image-4.10.0-041000-generic works linux-image-4.11.0-041100-generic works
By the way, I didn't mention is that even the kernel versions that work are far from perfect. When I first login one of the 2 external screens goes black or starts flickering, but there is a workaround. I have to switch to text mode (Ctrl+Alt+F1) and back. With the kernel versions that don't work I couldn't find any workaround, the external screens go black and they don't switch on anymore. Also, when I undock it while it's running it often crashes, and if it doesn't it crashes when I dock it back. Switching to text mode before docking/undocking seems to make more stable. That's most likely a different bug though. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1686189 Title: External monitor connecting problem on Intel graphics card Status in linux package in Ubuntu: Confirmed Status in xorg package in Ubuntu: Confirmed Bug description: I am facing a problem with Intel Graphics driver.
