[Bug] Blank Screen when adding GPU (Error in default config, fixed)

[Shaneee]

Issue first created here, MauriceNino/dashdot#1273

Upon adding gpu to the DASHDOT_WIDGET_LIST the app only shows a blank page with no widgets. I found the issue. The problem is with DASHDOT_GPU_LABEL_LIST.

By default it shows brand, model, memory but note the spaces. When they are removed brand,model,memory the app works as expected...

-e 'DASHDOT_WIDGET_LIST'='os,cpu,storage,ram,network'
-e 'DASHDOT_OS_LABEL_LIST'='os,arch,up_since'
-e 'DASHDOT_CPU_LABEL_LIST'='brand,model,cores,threads,frequency'
-e 'DASHDOT_STORAGE_LABEL_LIST'='brand,size,type'
-e 'DASHDOT_RAM_LABEL_LIST'='brand,size,type,frequency'
-e 'DASHDOT_NETWORK_LABEL_LIST'='type,speed_up,speed_down,interface_speed'
-e 'DASHDOT_GPU_LABEL_LIST'='brand, model, memory'
