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: nvidia-bug-report from Acer Aspire VN7-793G with rotation problem · GitHub
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
