Description Mark Alford 2006-06-28 00:16:04 UTC 
Thinkpad T23: middle mouse button stops working when I revive the computer after
a hibernate to disk.

This occurs in kernel-2.6.16-1.2108_FC4, kernel-2.6.16-1.2111_FC4, and
kernel-2.6.16-1.2115_FC4. It does NOT occur in kernel-2.6.13-1.1532_FC4.

It occurs even in text console mode (eg after typing CTRL+ALT+F1 to get a text
login screen) so I don't think it is an X problem.

If I do xev then the middle mouse button does not produce any event.

Update: if I boot with the selinux=0 kernel option, the problem goes away. Does
that mean it should be recharacterized as a SELinux bug?
Comment 2 Mark Alford 2006-08-01 19:02:38 UTC 
OK, it turns out that selinux=0 didn't really fix the problem. 

What seems to have fixed it is changing a BIOS setting. In the BIOS menu, Config
-> Keyboard/Mouse -> Trackpoint, change the setting from [AutoDisable] to
[Enabled]. The bizarre thing is that when I later changed the setting back to
[AutoDisable], the problem didn't come back.
