Ubuntu 14.04 - Desempenho lento / alto uso de cpu ao usar 2 monitores

0

Eu quero usar um segundo monitor (estender o primeiro) (ambos: Monitor LED 60,5 cm (23,8 Zoll) BenQ GW2470H EEK B 1920 x 1080 Pixel Full HD 4 ms HDMI ™, LED VGA VA)…

Tenho uma placa de vídeo onboard chamada: Intel Corporation 82G33 / G31 Express.

Further I use … Ubuntu 14.04 LTS, 
Memory: 3.9 GiB, 
Processor: Intel® Xeon(R) CPU E3110 @ 3.00GHz × 2, 
Graphics: Intel® G33 x86/MMX/SSE2 (82G33/G31 Express Integrated Graphics Controller), 
OS type: 32-bit, 
Disk: 310.7 GB, 
Motherboard: MS-7407

Com o ArandR eu posso usar os monitores um ao lado do outro… mas ao aplicá-lo… o desempenho está sofrendo. Eu posso ver no 'System Monitor' que CPU1 & amp; CPU2 está em 60-90% sem fazer nada… normalmente é como 1-10%…

... conectei o Monitor 1 com VGA a VGA e o Monitor 2 com um adaptador DVI-D para HDMI…

Então eu decidi comprar ...

Adaptador de Vídeo de Vídeo I-TEC USB 3.0 DVI HDMI VGA FullHD + Monitor Externo 2048x1152p Gráficos

desde que supostamente tem suporte / driver do Ubuntu. Eu segui a instalação aqui link e ele passou.

... conectei o Monitor 1 com o I-TEC USB 3.0 & amp; Adaptador HDMI para HDMI para HDMI e Monitor 2 com um adaptador DVI-D para HDMI…

Mas ainda é o mesmo problema. Desempenho lento. Então eu descobri que não tenho usb 3.0 na minha placa-mãe ...

Então eu comprei um '2 Port USB 3.0 adaptador USB-A PCI - SATA NEC / Renesas' e o sistema reconhece 'uPD720202 USB 3.0 Host Controller '

... mas ainda desempenho lento.

O que mais posso fazer para que o segundo monitor funcione sem problemas?
