[Kernel-packages] [Bug 1454160] Re: External monitor is disabled after resume
last good kernel: 3.18.3-031803-generic
first bad kernel: 3.18.4-031804-generic
I tried to do a git bisect but I didn't make it far because there are no tags
3.18.3/3.18.4 in kernel repo (kernel.org) I cloned.
These are the only tags containing 3.18:
v3.18
v3.18-rc1
...
v3.18-rc7
Is there another ubuntu specific repository that contains the tags I
mentioned (3.18.{3,4}) ?

Title:
External monitor is disabled after resume
Status in linux package in Ubuntu:
Incomplete
Bug description:
I have an external screen connected to my machine (T450s, via docking
station) and after resuming from suspend, my external monitor is
disabled.
After some trial and error I made an interesting observation: The
external monitor only stops working if suspend via systemctl suspend,
sudo pm-suspend, or via the hotkey on my keyboard (K750).
However, this problem does not occur if I suspend via the menu entry
in the upper right corner.
How is this even possible?
Mapping the suspend command from the upper right corner to a hotkey
would be a sufficient workaround. But which command is used by that
button?

[Kernel-packages] [Bug 1454160] Re: External monitor is disabled after resume
This bug still exists on 4.1.0-040100rc4-generic #201505181436 SMP Mon May 18 18:38:10 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux ** Tags added: kernel-bug-exists-upstream kernel-bug-exists-upstream-4.1-rc4 ** Changed in: linux (Ubuntu) Status: Incomplete = Confirmed -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1454160 Title: External monitor is disabled after resume Status in linux package in Ubuntu: Confirmed Bug description: I have an external screen connected to my machine (T450s, via docking station) and after resuming from suspend, my external monitor is disabled. After some trial and error I made an interesting observation: The external monitor only stops working if suspend via systemctl suspend, sudo pm-suspend, or via the hotkey on my keyboard (K750). However, this problem does not occur if I suspend via the menu entry in the upper right corner. How is this even possible? Mapping the suspend command from the upper right corner to a hotkey would be a sufficient workaround. But which command is used by that button?
