Two cursors on each tty console

[Jaakov]

Package: xorg
Version: 1:7.7+1ubuntu8

How to reproduce:
1) Make sure you have X and gpm running. Observe that under X you are having just one cursor displayed.
2) Press Ctrl+Alt+F1 to switch to tty1 console.
3) Observe that you have two cursors on the black screen: the square one is probably from gpm and responds to mouse movements, while the arrow one is as in X, is centered, and it does not move with the mouse. The screen foto is attached.

Expected: exactly one cursor under X, exactly one cursor on each console, both X and console cursors are operational.

Any help is appreciated.

Jaakov, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal as it will automatically gather and attach updated debug information to this report:

apport-collect -p xorg 1401842

Please ensure you have xdiagnose installed, and that you click the Yes button for attaching additional debugging information.

As well, given the information from the prior release is already available, testing a release prior to the development one would not be helpful.

Thank you for your understanding.

Dear Christopher:

Do the files available through the link contain a live edition I that I can start from a USB stick? If not, I will be unfortunately technically unable to test it.

Best,

Jaakov.

Dear developers:

Prior to some installations, more feedback I can give for now is that the problem also persists with
- gpm version 1.20.4-6.1
- xorg version 1:7.7+1ubuntu8.1
- two physical monitors attached through DVI
- the arrow, non-functional cursor is displayed on exactly one of them
- all the other , "usable" contents including the gpm rectangular cursor is duplicated as expected.

Best,

Jaakov

After checking today I found out that the daily image allows bootable USB sticks. The bug does not occur with
- xorg version 1:7.7+7ubuntu2
- gpm version 1.20.4-6.1
However, the test setups are different.
1) The resolution of the text mode on the console in both of the above scenarios was given by the grub line
GRUB_CMDLINE_LINUX="video=1366x768@60"
The resolution of the live version is different (default).
2) The latter of the above scenarios used two monitors, say, M1 and M2, and the console text was duplicated on both, with two cursors on M1 and one cursor on M2. In the live version, despite two monitors being physically attached, the console text is being displayed only on M2 (with one cursor).

After replacing

... quiet splash --
by
... video=1366x768@60

in the boot line of the live edition at grub start screen I obtained a configuration which is similar to the setup with two monitors. The bug does not occur: one cursor per conlsole copy. However, gpm had to be installed and run AFTER xorg started, while in the original two situtations gpm started with xorg during boot.
If the developpers are sure that the bug is no more in the new packages there due to better code, feel free to close the bug report. Otherwise, if I can do some more testing, please tell what and how to test.

Jaakov, given this is fixed in the latest release, would you need a backport to a release prior to Vivid, or may this be closed as Status Invalid?

Dear Christopher:

If you are sure about fixed, I would be grateful if this fix could get
into Trusty.

Thank you!

Jaakov.

[penalvch (penalvch)]

Jaakov, first, if you want a backport, you would need to follow all of the instructions in https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1401842/comments/2 , including advising if this is still fixed.

[Jaakov (jaakov-deactivatedaccount)]

Dear Christopher:

I see. I can do it only if a certain amount of privacy is ensured. Does apport-collect transmit/store also information like logins, hostname, IP, etc.?

Best,

Jaakov

I looked at what

apport-cli -f -p xorg --save xorg.apport

gives. I believe I could edit the result such that all the private data is replaced by placeholders (like John Doe, example.com, etc.) and post the file here. Would you be able to work from there onward?

[penalvch (penalvch)]

Jaakov, that would be fine.

[Jaakov (jaakov-deactivatedaccount)]

Here we go for the development version. If you need the data from a trusty version, please let me know.

[penalvch (penalvch)]

Jaakov, thank you for taking the time to report this bug and helping to make Ubuntu better. However, I am closing it because as per https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1401842/comments/6 the bug has been fixed in the latest development version of Ubuntu - Vivid Vervet.

This is a significant bug in Ubuntu. If you need a fix for the bug in previous versions of Ubuntu, please perform as much as possible of the SRU Procedure [1] to bring the need to a developer's attention.

[Jaakov (jaakov-deactivatedaccount)]

Thank you. However, I won't upload the tested fixed xorg package, since
the tested setup, as of 2015-05-06, has other user-interface bugs that
can affect me more than this two-cursors problem.

Namely, in the development version, the menu of the window manager
(lightdm?), which is usually found in the upper right corner, appears
thrice: once on the small monitor (upper right) and twice on the large
one (at about 70% land 100% length in the header). I expect it to appear
once or twice, however, depending on whether the screen contents is
extended or cloned. So suggesting the xorg-packages from that particular
date has a chance of making the situation worse for me. Once that other
problem is fixed, I can reconsider this decision.

By the way, what is the correct kernel-command-line argument for not
starting X at boot in trusty or vivid?

pfix=nox

doesn't work.

[Jaakov (jaakov-deactivatedaccount)]

BIOS update did not change the situation.

[penalvch (penalvch)]

Jaakov, please post the results of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

[Jaakov (jaakov-deactivatedaccount)]

Today I updated to the latest one that is available, which is:

# dmidecode -s bios-version && dmidecode -s bios-release-date
A14
09/24/2014

[Jaakov (j-k-v)]

As of today, this bug has not been observed in "wily" with the following versions of software and the same hardware.

gpm version: 1.20.4-6.1
xorg version: 1:7.7+7ubuntu4
BIOS: A15, 08/19/2015

Feel free to close the bug report.

Jaakov.
