O widget Conky parece ruim

Question

Estou tentando instalar o Malice-tab-conky, mas muitos erros ocorrem. Eu já consertei problemas com hddtemp, fonte e faltando $ endif. No momento isso funciona, mas é algo assim:

Ao executar o Conky, aqui está a saída do terminal:

conky: desktop window (240000a) is subwindow of root window (f5)
conky: window type - override
conky: drawing to created window (0x3600001)
conky: drawing to double buffer
conky: unknown variable '$pre_exec'

E por último, mas não menos importante, aqui está o código de .conkyrc :

conky.config = {

Eu tentei jogar com parâmetros diferentes, mas nada parece se referir ao tamanho do widget (apenas posicionamento). Como posso consertar isso?
