Acer Aspire VN7-793G (GTX1060) corrupt display upon rotation

Hi,

On Acer Aspire VN7-793G with Nvidia GTX 1060, upon rotating the screen with xrandr the display becomes corrupted:


nvidia driver version 384.98

nvidia-bug-report output: https://gist.github.com/dsd/3b533ef2ca07f04b9bbff5205912ea7a

Please let us know how we can help further diagnose this issue

Does this work if you turn on prime sync? i.e. using kernel parameter
nvidia-drm.modeset=1
In case of Ubuntu, you might have to add a file in /etc/modprobe.d/ containing
options nvidia_XXX_drm modeset=1
with XXX being the major version of the installed nvidia driver.
After that, run
update-initramfs -u

This is also reproducible on Asus X705UQ (nvidia 940MX).

Turned on that parameter and checked with:

root@endless:~# cat /sys/module/nvidia_drm/parameters/modeset 
Y

Started X, set 90 degrees rotation, and the behaviour is still as above.

The display on these laptops is done via the Intel display controller.

I checked and this appears to be a bug in xf86-video-intel. Switching to the modesetting driver makes the problem go away.

Probably not an nvidia issue then - sorry for the noise
