Lenovo X240 in Dock, bad resolution on logon and no mouse pointer

[Adam]

Laptop works perfectly when not docked.

If I boot when in the dock, the logon screen is highly corrupted. I can enter my username and password anyway and then it logs me in, I can see the screen on the external display, and everything works EXCEPT my mouse pointer is invisible! I can move the mouse around and if I get it in the right place (for example, I can get to a corner) and click it works, so the OS "knows" where the mouse pointer is but I just can't see it.

If I boot up and log in with the laptop undocked, and then place in the dock, everything works perfectly.

The display corruption issue was resolved by swapping in an HDMI cable for the VGA cable.

Upgraded the BIOS, seeing same exact symptoms as before.

Adam, did this problem not occur in a release prior to 15.10?

[Adam (ajacobs)]

Yes, that is correct. This problem presented immediately after I upgraded to 15.10 and never existed previously.

[penalvch (penalvch)]

Adam, if you boot into a kernel from a prior release where this was working, is this still reproducible?

[Adam (ajacobs)]

Yes, I just tested with kernel 3.19.0-33 and it is still reproducible.

[penalvch (penalvch)]

Adam, to see if this is already resolved, could you please test for this via http://cdimage.ubuntu.com/daily-live/current/ and advise to the results?

[Adam (ajacobs)]

Tried running that off of a USB drive (created using Startup Disk Creator on Wily) and only get "boot error."

[Adam (ajacobs)]

Burnt it to a DVD, got farther, but it still crashes.

[Adam (ajacobs)]

OK, I think there are actually two separate bugs here.

(1) The display corruption issue was resolved by swapping in an HDMI cable for the VGA cable. Still, this worked before so it's a regression, but not a really horrible one. I should have been using an HDMI cable anyway.

(2) The mouse pointer issue is resolved if I restart lightdm. There are several open bugs about that and discussions in various fora.

[penalvch (penalvch)]

Adam, thanks for the follow up.

Let this report focus on 1), and 2) can be pursued via separate report targeted to lightdm.

Despite this, when you boot up with the computer in the docking station, are there any crash files in /var/crash?
