synaptics driver is not loaded after upgrade to xen-4.4.1

[davidshen84]

Hi,

My system is Gentoo x64, boot by UEFI, and with KDE. My system is on my laptop. I just updated my system.

After the system has booted with xen. I noticed the screen halted at the start up splash screen for a long time before it shows the desktop. And I cannot use my touchpad, and kcm-touchpad says the 'synaptics' driver is not loaded. However my USB mouse is working.

Secondly, it seems my dom0 can only use one of my two cores.

Before the upgrade, my xen and KDE works very well, and I can create HVM. Right now, I have no clue how to troubleshoot this problem.


Thanks,
David
