在Fedora Linux上如何找出我的NVDIA显示卡的内存大小。
如何在Linux上找到我的VIDEO卡(VGA)内存大小？
您需要使用以下命令来查找Linux上的图形卡(VGA)内存：

• lspci命令是一个实用程序，用于显示有关系统中所有PCI总线以及与其连接的所有设备的信息。
• /var/log/Xorg.0.logXorg日志文件。
• lshw命令列出Linux上的CPU，CPU和其他硬件。
• glxinfo命令在给定的X显示器上查看有关Linux上GLX实现的信息。

lspci命令示例，用于查找Linux上的视频卡(GPU)内存RAM大小

打开终端，然后执行lspci命令以列出Linux上的PCI设备：

$ lspci

输出：

您需要在指定的域00：02.0 VGA中使用称为设备的字符串(以红色突出显示以显示内存信息)：

$ lspci -v -s 00:02.0

输出示例：

00:02.0 VGA compatible controller: Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device (rev 03) (prog-if 00 [VGA])
        Subsystem: Giga-byte Technology Unknown device 2562
        Flags: bus master, fast devsel, latency 0, IRQ 177
        Memory at d0000000 (32-bit, prefetchable) [size=128M]
        Memory at d8200000 (32-bit, non-prefetchable) [size=512K]
        Capabilities:

此列表显示了具有128 MB视频RAM的英特尔视频卡。
如果找不到指定域中的设备，请使用以下命令并查找显示卡名称和内存字段：

$ lspci -v | less

识别Linux上的板载Intel/AMD或Nvidia专用GPU

只需运行以下lshw命令。
它是提取有关Linux机器硬件配置的详细信息的小工具：

$ sudo lshw -C display

Linux使用命令行找出视频卡GPU内存RAM大小

另一种选择是运行以下命令：

$ glxinfo | more

可以如下使用egrep命令来过滤掉信息：

$ glxinfo | egrep -i 'device|memory'

要获取摘要，即简要信息，请运行：

$ glxinfo -B

Xorg日志文件以获取Linux上的GPU信息

打开命令行终端(选择应用程序>附件>终端)，然后执行：

$ grep -i --color memory /var/log/Xorg.0.log

输出示例：

(--) Aug 02 12:16:20 NVIDIA(0): Memory: 1048576 kBytes
(II) Aug 02 12:16:21 NVIDIA: Using 768.00 MB of virtual memory for indirect memory access.
(==) NVIDIA(0): Disabling shared memory pixmaps

以上输出表明我的Nvidia卡的RAM为1024MB。
