Description of problem:
I had a working X configuration with kernel 2.6.2-1.81 installed. I
performed an update via 'yum update' and installed the recommended
updates (kernel-2.6.2-1.85 being one of them). I rebooted using
2.6.2-1.85; when I typed 'startx' I was informed my mouse wasn't
present. I spend much of day searching google and the mailing lists
with not much help. So I rebooted using the 2.6.2-1.81 kernel and all
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Upgrade to kernel-2.6.2-1.85
Actual Results: X windows starts and then fails with the following
xf86OpenSerial: cannot open device /dev/psaux
No such file or directory.
Expected Results: X windows loads with cursor
I've reverted back to 2.6.2-1.81 with success.
/dev/psaux has been superceded by /dev/input/mice in 2.6
please change your XFree config
the rpm should do that automatically.
Ok. That's fine and I've updated my XF86config to use /dev/input/mice.
My question is why did all 2.6 kernels I've tried before 2.6.2-1.85
allow the use of /dev/psaux? Was it something you just caught, Arjan?
/dev/psaux is the old legacy interface. We need to catch and convert
all users of it, so disabling is the only way to do that ;)
In addition X might open /dev/psaux AND /dev/input/mice and get events
double that way. X normally deals with that but it can lead to weird
