Introduction
If you have a laptop and your touchpad is not detected please follow the steps described here: DebuggingTouchpadDetection.
Problems with mouse detection typically fall into one off these categories:
- Your mouse doesn't work at all.
- Your mouse stops working after a while.
- Some mouse buttons or scrollwheels don't work (as expected).
How to file a bug report
Before filing a bug please check the list of known bugs at the end of this document.
Mouse related bugs should initially be filed via the command: ubuntu-bug xorg
If the bug turns out to be a kernel bug or a bug in another package, bug triagers can re-assign the bug.
General information
For all bug categories the following general information should be provided:
What brand and model is your mouse.
How is your mouse connected to your PC: serial, PS/2, USB, USB wireless, ...
What mechanism does your mouse use: ball mouse, optical, trackball, ...
How many physical buttons and scrollwheels does you mouse have?For a USB mouse enter the following command on a terminal/console:
lsusb -v > ~/lsusb-v
Open a terminal/console and enter the following commands (minimal information as described in KernelTeamBugPolicies):
uname -a > ~/uname-a cat /proc/version_signature > ~/version_signature sudo lspci -vvnn > ~/lspci-vvnn
Attach ~/lsusb-v, ~/uname-a, ~/version_signature and ~/lspci-vvnn to the bug report as seperate attachments.
In case your mouse doesn't work at all
Provide the general information.
- If you have a PS/2 mouse make sure it was connected before booting Ubuntu, if you have a USB mouse unplug it and replug it to see if it starts working.
Enter the following command in a terminal/console:
dmesg > ~/dmesg
Attach ~/dmesg and your /var/log/Xorg.0.log to the bug report in seperate attachments.
In case your mouse stops working after a while
- Test if your mouse works in a second computer, or test a second mouse in your computer. Several issues are related to the specific hardware/Bios configuration, try to disable ACPI.
Provide the general information.
Direct after logging in to GNOME, KDE or Xfce open a terminal and enter the following commands:
dmesg > ~/dmesg_boot cp /var/log/Xorg.0.log ~/Xorg.0.log
- Wait until your mouse stops working. If you have a USB mouse unplug it an replug it to see if it starts working again.
- Open a Virtual Terminal by pressing Ctrl-Alt-F1.
Enter the following commands:
LANG=C dmesg > ~/dmesg diff -ns ~/dmesg_boot ~/dmesg > ~/dmesg_diff cp /var/log/Xorg.0.log ~/Xorg.0.log_tmp diff -ns ~/Xorg.0.log ~/Xorg.0.log_tmp > ~/Xorg.0.log_diff
Attach ~/dmesg_boot, ~/dmesg_diff, ~/Xorg.0.log and ~/Xorg.0.log_diff to the bug report in separate attachments.
In case some mouse buttons or scrollwheels don't work (as expected)
Provide the general information.
Open a terminal and enter the following commands:
xmodmap -pp > ~/xmodmap-pp xev | grep -i button
Put the mouse cursor into the rectangle and push your mouse buttons. Mention in the bug report which button number is reported, e.g. left = 1, scrollwheel up = 4, horizontal scrollwheel left = 6, thumb button = 8, pinkie button = 9, ...Attach your /var/log/Xorg.0.log and ~/xmodmap-pp to the bug report in seperate attachments.
