CentOS查看顯卡及GPU相關信息

lspci  | grep -i vga

這樣就能夠顯示機器上的顯卡信息，好比

[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)



若是想看詳細的信息，好比 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])

能夠看到GT240的顯存是 256M



可是個人系統上實際上是裝了兩塊顯卡的，還有一塊顯示不出來，這個時候，對於nvidia顯卡的話能夠用nvidia-smi命令來查，查看GPU也是用這個命令

[root@localhost conf]# nvidia-smi

能夠看到，還有一塊顯卡是 GTX 570， 顯存是 1279M，也就是咱們用lspci看到的 01:00.0
