Initial state: laptop on dock with lid closed. Using external display. (tried VGA and DVI, same result) At boot-up the external screen is in the proper resolution. When Xorg starts the resolution switch to the largest between the LVDS and the external display, in my case being 1336x768 (mas LVDS resolution) while my external display should be by default 1920x1200. Problems: 1) The lid detection does not work hence LVDS is not being turned off (refers to bugs #11455, wontfix). I can't believe that more than 5 years after the initial creation of that bug that there cannot be a proper fix now to detect this in a decent matter, no? 2) Should be extending the Xorg to the detected "max" resolution, all the time, by default. Every time I login I have to extend the xorg to 1920x1200 manually and either turn-off the LVDS or keep it as is (1336x768), configured in cloned therefore LVDS only shows a portion of the 1920x1200 screen visible area. If xorg would do that by default that would already solve part of the problem. This bug as also been seen with radeon driver (#14500) which makes me doubt that it might be more relevant with the overall xorg behaviour and not be driver specific? While looking through the bug database I also cam accross this one (#32922, wontfix). It does somewhat address theses two issues but only 1) got answered with a wontfix. Lastly, Windows does handle this really well. I just hope this can also be solved on the linux side instead of having to make ugly hack like this one: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/573312 I'm really willing to help-out, just let me know what can I do. Thnx in advance for the help! Regards.

Created attachment 71850 [details] Xorg log file
Interestingly, from the Xorg.0.log there are theses messages that suprised me: [ 8.755] (II) config/udev: Adding input device Lid Switch (/dev/input/event1) [ 8.755] (II) No input driver specified, ignoring this device. [ 8.755] (II) This device may have been added with another device file.
Both bugs are still wontfix, but not because we don't care here from the drm/i915 driver team, but because our driver can't fix this ....

The default is just that, and imo it's a sane one - the aim here is that we have the highest chance that the user can see the login screen: Which means enable as manu outputs as possible, but restrict the output size to the smallest one. Otherwise if e.g. the largest output doesn't work for some reason, the user won't see the login/desktop because he only sees a tiny part on the one, working screen. You're correct that this is X server behaviour shared by all drivers and for the above reason likely wontfix even there. If you want a different default, your desktop/login manager needs to restore that at every boot-up to your preferred setup. If your login manager/DE doesn't provide such a mechanism, you need to file a bug/feature wishlist there. Hope this explains why we close all such bugs as wontfix. Sole exception is if the default picker gets confused becuase the kernel detects an output which isn't really there (ghost output bugs). That's a kernel issue and needs to be fixed. But afaict this is not the case here.
Thnx for the reply. Just so I get this right: 1) based on previous Comment Info #3, I should still consider this bug as an ACPI problem even if a lid device was detected, right? 2) I must then presume that the associated device does not work as expected otherwhise the Intel Xorg driver would have make usage of it, known that the lid was closed and therefore turned-off the LVDS display and only be using the external one? Just confirming so I opened up a new bug entry at the appropriate place. Thnx and merry christmas ;-)

But if the ACPI lid stuff doesn't work correctly (you could check the sysfs files I think or in procfs through ssh whether it works). If that doesn't work you need to file an ACPI bug. For the desktop integration either write your own script or yell at the people doing your DE ;-)
