The default info uses the device_performance() function which uses the cpu_mem_disk() function, which in turn uses the virtual_mem_usage() function. You could copy the cpu_mem_disk() function and remove the part which uses the virtual_mem_usage() function. I did it like this...
removal_vmem_test function
concatenate(
if(cpu_usage_available(), concatenate("cpu: ", cpu_usage(), "% "), ""),
if(mem_usage() > 0, concatenate("mem: ", round(mem_usage()), "% "), ""),
if(hdd_usage() > 0, concatenate("disk: ", round(hdd_usage()), "% "), "")
)
device_performance_no_vmem function
if(
string_size(removal_vmem_test()) > 0,
concatenate(removal_vmem_test(), "
"),
""
)
On the device's appearence window edit the entry in the label field and replace device_performance() with device_performance_no_vmem() (or whatever you devide to call the function) and that should do it.
