Release Notes

Do not use Wacom Display Settings touch key.

None.

Do not stretch a window more than 4096 pixels, horizontally or vertically.

Run pcoip-register-host again, or run pcoip-register-host using the IP address of the proxy server instead of the name.

When the system is rebooted, the older kernel modules from the initramfs are loaded again, which means the userspace libraries can't talk to the new driver.

To resolve the issue:

To resolve the issue after the driver is installed but before rebooting:

sudo dracut -fv

 To resolve the issue after the driver is installed and after rebooting:

sudo modprobe -r nvidia_drm nvidia_modeset nvidia sudo dracut -fv sudo reboot

If possible, upgrade to a newer operating system that comes with a newer kernel.

Configure the Wacom tablet to be USB bridged on the zero client.

On multi-monitor workstations the tablet is mapped to the entire desktop by default. If a tablet is mapped to a single display on a multi-monitor workstation, configure both the zero client tablet mapping setting and the host tablet mapping setting. Use the Zero client OSD User Setting > Tablet Mapping screen to map the tablet to a single display. Change the host tablet mapping setting by configuring the xsetwacom MapToOutput setting. The local and remote cursors will not be in sync if the zero client and host settings are not configured properly.

Enable the USB permissions on the Zero Client to bridge the Wacom device. More information can be found in the Zero Client firmware Administrators' Guide. 

Below is a script that will install a known working kernel version, ensure it is the default booted kernel and that updates will not change the default kernel or remove the working version. It should be run as root.

#!/bin/sh

KERNEL_VERSION=3.10.0-693.21.1.el7

# ensure the default is set to the saved entry
sed -i 's/GRUB_DEFAULT=.*/GRUB_DEFAULT=saved/' /etc/default/grub

# make sure installing a new kernel package does not change the saved entry
sed -i 's/UPDATEDEFAULT=.*/UPDATEDEFAULT=no/' /etc/sysconfig/kernel

# install kernel/kernel-devel for the latest known working kernel version
yum install -y kernel-${KERNEL_VERSION} kernel-devel-${KERNEL_VERSION}

# set the installonly attribute to keep so that installing new kernels does not remove our known working kernel
yumdb set installonly keep kernel-${KERNEL_VERSION}

# find the name of the kernel we just installed in the grub config
GRUB_KERNEL_NAME="$(awk -F\' /^menuentry/{print\$2} /etc/grub2.cfg | grep ${KERNEL_VERSION} | grep -vi rescue)"

# set the grub default
eval grub2-set-default \"${GRUB_KERNEL_NAME}\"

# regenerate the grub config
grub2-mkconfig -o /boot/grub2/grub.cfg

In order to use MapToOutput to map the Wacom tablet to a particular display, one must set the tablet mapping in the Zero Client OSD. From User Settings -> Tablet, use the stylus to select the corresponding display. Click OK to save the setting.

Add a HBAC service for the pcoip-session PAM service and any necessary HBAC rules to allow users to connect via PCoIP.

Manually set timezone on the host Virtual Machine.

1. Delete the contents of C:\ProgramData\Teradici\PCoIPAgent\licensing\5 in Windows, or /var/lib/pcoip-agent/licensing/5 (requires root permissions) in Linux

2. Restart the appropriate agent service (PCoIP Graphics Agent or PCoIP Standard Agent on Windows, or pcoip-agent on Linux)

3. If using Teradici Cloud Licensing (not using a local license server), re-register the host.

Unity is not supported with the PCoIP Linux Agent. Instead, use kubuntu-desktop.

Reduce the number of monitors, or change the vGPU profile to increase the frame buffer memory.

Switch the daemon to run in per-user mode, which is the default.

Manually delete the undesired taskbars.
