With WSL2 when $DISPLAY is set, Theme and Icons takes minutes to complete

dotnetCarpenter commented 3 years ago

Description

With $DISPLAY unset, neofetch takes around 2 seconds on my machine.

With $DISPLAY set, neofetch always takes more than 6 minutes (did 3 test runs).

[X] Does this issue still occur in the master branch? (Required if issue)

My DISPLAY variable below which expands to 172.28.16.1:0 (the Windows host's IP address):

export DISPLAY="`sed -n 's/nameserver //p' /etc/resolv.conf`:0"

Neofetch version

Neofetch 7.1.0 - installed via sudo make install

Any reason why DISPLAY is set?

dotnetCarpenter commented 3 years ago

I need to run a python3 script that uses python3-tk. I found a Microsoft Tech article about installing VcXsrv Windows X Server and used that approach to get Baseline-JPEG-Decoder working.

There is a newer approach but unfortunately it is Windows 11 only. It's unclear if the newer approach sets DISPLAY.

Also notice that the speed-up in the first case where $DISPLAY is unset, is because neofetch simply does not query for Theme and Icons.

EDIT: It also fetches the GPU (which seems to be a false positive in this case). My actual GPUs are:

GPU 0 Intel(R) HD Graphics Family (HD Graphics 4400)
GPU 1 AMD Radeon HD 8600M Series (Radeon HD 8670M)

Hmmm just a observation that might be useful

After downgrading my GPU 1 driver (AMD), neofetch became super fast! On second thought - this is the Ubuntu package neofetch.

Note that GPU is now defined whereas it was not before. This version of neofetch is my Ubuntu 21.04 package, which might explain the speedup.
