Bug ID: 361918
Summary: NVIDIA Driver with External Display on Left, Fails
Product: user-manager
Version: 5.5.5
Platform: Kubuntu Packages
URL: https://www.kubuntuforums.net/showthread.php?69777-NVI
DIA-Driver-with-External-Display-on-Left-Fails/page2
OS: Linux
Status: UNCONFIRMED
Severity: major
Priority: NOR
Component: kcontrol module
Assignee: afies...@kde.org
Reporter: sbc_hates_s...@yahoo.com.au
The URL is on the Kubuntu Forums where there is discussion and examples of this
problem. With an hdmi connection to the External Monitor, and when the System
Settings has External monitor on the Right, cursor movements between left and
right across the displays works correctly. However, if System Settings is used
to shift the external monitor to the Left of the primary display, and the
system rebooted, after the change the left monitor image shifts horizontally
with cursor movement. Also, System Settings shows no display information under
these conditions.
When dealing with these problems, I can recover by deleting
~/.local/share/kscreen.
My hardware is an ASUS R501VM-S3150, with a NVIDIA GT630M. The operating system
is Kubuntu 16.04 and the NVIDIA driver is the nvidia-364.15
Reproducible: Always
Steps to Reproduce:
1.Boot the system and open the NVIDIA X Server Settings and select NVIDIA.
Shut Down and connect an external monitot via hdmi and reboot. Open System
Settings > Display and Monitor and locate the external monitor on the left of
the primary display.
2. Shut Down and Re-Boot
3. Use the cursor to move between the left and right screens and note the
shifting image on the Left External display
Actual Results:
Image on the Left external display moves with cursor movement. LibreOffice
Presentation does not work correctly, ie the control panel for Slide Shows is
not presented. Also, Display Settings does not show any monitor.
Expected Results:
I expect to be able to move the cursor between screens without the background
changing.
I also expect a Slide Show from LibreOffice to work correctly with a control
screen visible.
I also expect the System Settings to show the displays.
I also expect glxgears to show manny more than 60fps.
