CentOS查看显卡及GPU相关信息

lspci  | grep -i vga

这样就可以显示机器上的显卡信息，比如

[root@localhost conf]# lspci | grep -i vga
01:00.0 VGA compatible controller: nVidia Corporation Device 1081 (rev a1)
02:00.0 VGA compatible controller: nVidia Corporation GT215 [GeForce GT 240] (rev a2)
08:05.0 VGA compatible controller: ASPEED Technology, Inc. ASPEED Graphics Family (rev 10)



如果想看详细的信息，比如 GeForce GT 240，即 02:00.0

[root@localhost conf]# lspci -v -s 02:00.0
02:00.0 VGA compatible controller: nVidia Corporation GT215 [GeForce GT 240] (rev a2) (prog-if 00 [VGA controller])

可以看到GT240的显存是 256M



但是我的系统上其实是装了两块显卡的，还有一块显示不出来，这个时候，对于nvidia显卡的话可以用nvidia-smi命令来查，查看GPU也是用这个命令

[root@localhost conf]# nvidia-smi

可以看到，还有一块显卡是 GTX 570， 显存是 1279M，也就是我们用lspci看到的 01:00.0
