问题描述
我刚刚在我的新笔记本电脑上安装了15.04，安装程序提示计算机名为carl-lenovo-g710。
笔记本电脑确实是联想G710，但安装人员是怎么知道的？
我尝试了sudo lshw | grep -i product，它产生了：
product: Intel(R) Pentium(R) CPU 3550M @ 2.30GHz
product: Xeon E3-1200 v3/4th Gen Core Processor DRAM Controller
product: 4th Gen Core Processor Integrated Graphics Controller
product: Xeon E3-1200 v3/4th Gen Core Processor HD Audio Controller
product: 8 Series/C220 Series Chipset Family USB xHCI
product: xHCI Host Controller
product: xHCI Host Controller
product: Flash Card Reader/Writer
product: Card Reader
product: Lenovo EasyCamera
product: 8 Series/C220 Series Chipset Family MEI Controller #1
product: 8 Series/C220 Series Chipset Family USB EHCI #2
product: EHCI Host Controller
product: 8 Series/C220 Series Chipset High Definition Audio Controller
product: 8 Series/C220 Series Chipset Family PCI Express Root Port #2
product: QCA9565 / AR9565 Wireless Network Adapter
product: 8 Series/C220 Series Chipset Family PCI Express Root Port #3
product: QCA8172 Fast Ethernet
product: 8 Series/C220 Series Chipset Family USB EHCI #1
product: EHCI Host Controller
product: HM86 Express LPC Controller
product: 8 Series/C220 Series Chipset Family 6-port SATA Controller 1 [AHCI mode]
product: 8 Series/C220 Series Chipset Family SMBus Controller
product: DVDRAM GTA0N
product: ST1000LM024 HN-M
然后我尝试了sudo lshw | grep -i 710，没有任何结果。
所以lshw不知道品牌和型号。那么这些信息存储在哪里？
最佳解决思路
Ubuntu安装程序称为ubiquity。无处不在2.3.18的变更记录提到
"Use dmidecode to get a more unique suffix for the hostname (LP: #628087)."
确切的python代码是：
def dmimodel():
model = ''
kwargs = {}
if os.geteuid() != 0:
# Silence annoying warnings during the test suite.
kwargs['stderr'] = open('/dev/null', 'w')
try:
proc = subprocess.Popen(
['dmidecode', '--quiet', '--string', 'system-manufacturer'],
stdout=subprocess.PIPE, universal_newlines=True, **kwargs)
manufacturer = proc.communicate()[0]
if not manufacturer:
return
manufacturer = manufacturer.lower()
if 'to be filled' in manufacturer:
# Don't bother with products in development.
return
if 'bochs' in manufacturer or 'vmware' in manufacturer:
model = 'virtual machine'
# VirtualBox sets an appropriate system-product-name.
else:
if 'lenovo' in manufacturer or 'ibm' in manufacturer:
key = 'system-version'
else:
key = 'system-product-name'
proc = subprocess.Popen(
['dmidecode', '--quiet', '--string', key],
stdout=subprocess.PIPE,
universal_newlines=True)
model = proc.communicate()[0]
if 'apple' in manufacturer:
# MacBook4,1 - strip the 4,1
model = re.sub('[^a-zA-Z\s]', '', model)
# Replace each gap of non-alphanumeric characters with a dash.
# Ensure the resulting string does not begin or end with a dash.
model = re.sub('[^a-zA-Z0-9]+', '-', model).rstrip('-').lstrip('-')
if model.lower() == 'not-available':
return
if model.lower() == "To be filled by O.E.M.".lower():
return
except Exception:
syslog.syslog(syslog.LOG_ERR, 'Unable to determine the model from DMI')
finally:
if 'stderr' in kwargs:
kwargs['stderr'].close()
return model
编辑：您可以通过以下方式下载代码来浏览自己的代码：
cd /tmp
apt-get source ubiquity
次佳解决思路
dmidecode显示有关系统的所有信息。看看使用命令：
sudo dmidecode | grep -A 9 "System Information"
