Idea #7: Better support for docking stations

Written by JFreak the 28 Feb 08 at 14:17. Category: Others. Related project: Nothing/Others. Status: New
Rationale
When removing a laptop from a docking station the screen on the laptop stays black. A reboot is needed to get something back on the screen.
When plugging my laptop back into the docking station it does not use the screen from the docking station.
Furthermore it has difficulties handling that the laptop monitor is widescreen and the one connected to the docking station is 4:3

I would like to have automatic switching between configurations.
For example, I use dual head when docked, but when I restart undocked Ubuntu thinks the external monitor is still there.

this is a must have. It makes Ubuntu more accessible for companies. Thinkpads are the corporate laptops used by decision taking people that use docking stations. Ubuntu should offer better support for ejecting (screen, external drives, power, keyboard, mouse, etc...).

I agree, support for docking stations is a must for business use.

I posted something similar earlier about USB audio not working correctly either in docked/undocked configs. I was unable to ever get dual monitor (or even docked monitor) support to work because my laptop is a wide screen but my desktop monitor isn't. I blame most of that on the video card manufacturer's (ATI) shoddy support for Linux (although that is supposedly getting better).

There definitely needs to be some improvement in support for multiple configs, and "hot" changes between them. This may be a kernel or core Debian issue though, as opposed to something Ubuntu has much control over. It is imperative that it be fixed though for more acceptance in the corporate world. Laptops are rapidly gaining ground as desktop replacements for a mobile workforce. Unfortunately- they present a lot more problems for Linux because of proprietary hardware and multiple hardware configs. My laptop has to work in the office (at and away from my desk), at home (at my desk or on my couch) and on the road. Ubuntu does a fair job of dealing with these different configs, but could still be improved quite a bit. I often find myself rebooting every time I change. I guess I'm getting used to it, which I really shouldn't.

I could not agree more. I have had a series of Dell Latitudes, all with docking stations, and this has been a constant pain.

The docking station audio port *never* works. In addition, I have to run a script on boot to detect whether or not I'm on the dock (and therefore have an external monitor), which then copies the appropriate xorg.conf file. It *works*, but it's a kludge.

@Shosta, definitely true--having to restart when going on and off the dock is a major headache. Users in corporate environments are used to XP's superior support of this functionality.

i agree to.

when i dock my dell 820 laptop, display on external monitor works but display of the internal lcd is always activate too.

and as the laptop is closed, it's very very HOT.

i can turn off with xrandr in command line, but it can be great if we can desactivate it automaticaly when the laptop is docked.

Docking station support should be a high priority, but please aim for the long-term and build support for hot-plugging. A restart of the X server would be more tolerable than a restart of the whole system.
