如何找到我的显卡的内存
sudo lshw -C display 显示……
*-display description: VGA compatible controller product: Broadwell-U Integrated Graphics vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 09 width: 64 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:63 memory:c3000000-c3ffffff memory:d0000000-dfffffff ioport:7000(size=64) *-display description: 3D controller product: GF117M [GeForce 610M/710M/820M / GT 620M/625M/630M/720M] vendor: NVIDIA Corporation physical id: 0 bus info: pci@0000:09:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list configuration: driver=nouveau latency=0 resources: irq:65 memory:c4000000-c4ffffff memory:b0000000-bfffffff memory:c0000000-c1ffffff ioport:4000(size=128)
然后我试了一下
amruth@HP-Ci5:~$ lspci | grep VGA
返回
00:02.0 VGA compatible controller: Intel Corporation Broadwell-U Integrated Graphics (rev 09)
然后我试了一下
amruth@HP-Ci5:~$ lspci -v -s 00:02.0
返回
00:02.0 VGA compatible controller: Intel Corporation Broadwell-U Integrated Graphics (rev 09) (prog-if 00 [VGA controller]) Subsystem: Hewlett-Packard Company Device 2337 Flags: bus master, fast devsel, latency 0, IRQ 64 Memory at c3000000 (64-bit, non-prefetchable) [size=16M] Memory at d0000000 (64-bit, prefetchable) [size=256M] I/O ports at 7000 [size=64] Expansion ROM at [disabled] Capabilities: Kernel driver in use: i915
从中我可以得出结论，我的显卡只有256Mb。 这是我新推出的HP笔记本电脑[HP 15-r240TX笔记本电脑（第5代Ci5 / 8GB / 1TB /免费DOS / 2GB图形）（L8P42PA）]来自Flipcart。 所以我计划要求更换。 谢谢回复。
lspci | grep VGA
标记前面的数字。 然后做…
lspci -v -s {digits}
我的机器示例：
~$ lspci | grep VGA 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Whistler [Radeon HD 6630M/6650M/6750M/7670M/7690M]
和
$ lspci -vm -s 01:00.0 Device: 01:00.0 Class: VGA compatible controller Vendor: Advanced Micro Devices, Inc. [AMD/ATI] Device: Whistler [Radeon HD 6630M/6650M/6750M/7670M/7690M] SVendor: Acer Incorporated [ALI] SDevice: Radeon HD 6650M
将显示video卡的所有细节。 编辑：似乎并非所有显示卡的内存。 这种方法不仅适用于您的显卡：有线和无线网卡的详细信息，USB控制器也会显示（只需将命令更改为02：00.0,03：00.0。我的音频在01：00.1;只需检查1号数字命令）。
另一种方法：
lspci -v | grep VGA -A12 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Whistler [Radeon HD 6630M/6650M/6750M/7670M/7690M] (prog-if 00 [VGA controller]) Subsystem: Acer Incorporated [ALI] Radeon HD 6650M Flags: bus master, fast devsel, latency 0, IRQ 35 Memory at b0000000 (64-bit, prefetchable) [size=256M] Memory at c0300000 (64-bit, non-prefetchable) [size=128K] I/O ports at 3000 [size=256] Expansion ROM at c0340000 [disabled] [size=128K] Capabilities: Kernel driver in use: fglrx_pci
- 256MB
从官方回购或通过终端下载SystemInfo：
sudo apt-get install sysinfo
然后，从终端直接打开：
sysinfo
现在你可以看到所有你需要知道的:)
尝试使用以下命令：
lspci -vvnn | grep -Pzo "(?s)\[03.*?\sprefetchable\) \K\[size=(\d+)M\]"
喜欢grep for \[03因为video卡并不总是与[0300] VGA compatible controller一起列出。 它们可以是[0380] Display controller或[0302] 3D controller 。
我的系统的结果：
[0300]: Intel Corporation 3rd Gen Core processor Graphics Controller [8086:0166] (rev 09) (prog-if 00 [VGA controller]) Subsystem: Lenovo Device [17aa:21fb] Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx+ Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=fast >TAbort- SERR-
是：
[size=256M]
