Description Tomas Pelka 2013-09-23 12:38:56 UTC

Description of problem:
the cursor is not displayed on USB attached multiseat device Plugable UD-160-M.
Cursor came back on successful login. 

Version-Release number of selected component (if applicable):
gdm-3.8.4-6.el7
gnome-shell-3.8.4-5.el7
xorg-x11-server-Xorg-1.14.2-10.el7

How reproducible:
100%

Steps to Reproduce:
1. boot rhel7 machine
2. attache Plugable UD-160-M
3.

Actual results:
no cursor on gdm

Expected results:
there should be a cursor

Additional info:
on the login screen it seems that cursor is just invisible, it doesn't meant it is messing

screen-saver works as expected, I mean cursor is displayed

Comment 2 Ray Strode [halfline] 2014-02-07 20:38:55 UTC

So:

1) gnome-shell (well mutter) is calling XDefineCursor at startup. 
2) gnome-settings-daemon is calling XFixesHideCursor() at startup and XFixesShowCursor() when the user moves the mouse plugged into the device
3) The cursor doesn't show up though.
4) If something calls XDefineCursor a second time (say hover over the password entry, or restart gnome-shell) then the cursor suddenly appears

It looks like an X server bug of some sort.  Since it only happens with pluggable devices, i wonder if it's some sort of hotplug race?

Moving to X server.

Does this build fix it?

Well it had better, because that change is included in RHEL7 now.
