Mouse movement/clicks are limited on display

[auggie246]

I am currently setting up xrdp on a GCP VM with nvidia L4 GPU. I am using @jsorg71 nvenc branch for both xrdp and xorgxrdp

The following is my configuration while building

# for xrdp
XRDP_NVENC_CFLAGS="-I/usr/local/cuda-12.4/include -I$HOME/Video_Codec_SDK_12.2.72/Interface" XRDP_NVENC_LIBS="-lcuda -lnvidia-encode" ./configure --enable-vsock --enable-jpeg --enable-fuse --enable-pixman --enable-opus --enable-mp3lame --enable-x264 --enable-nvenc

# for xorgxrdp
./configure --with-simd --enable-lrandr

Mouse is limited to work in a very small region (green being the max point, black being where i was right clicking)

I have also tried changing to Virtual 1920 1080 to Virtual 4000 2000 but the usable area just shifted to the center with much of the sides unusable

UPDATE: Although I am using a GRID L4 GPU on GCP. The following section was not required. removing it allowed me to click anywhere

SubSection "Display"
    Virtual 1920 1080

That's great @auggie246 I'll give it a try. BTW, what driver version are you running?
