Q. How do I find out which graphics card installed in my Linux desktop system? I’m using Ubuntu Linux. I don’t want to open up the computer hardware to just see the make and model of the graphics card in a system.
A. You don’t have to open the hardware to see the make and model of the graphics card in a system. There is direct method provided by using lspcicommand.
This command will usually tell you the vendor and model of your card. Open xterminal or shell prompt and type the command:
$ lspci -v
$ lspci -v | less
00:01.0 PCI bridge: Broadcom BCM5785 [HT1000] PCI/PCI-X Bridge 00:02.0 Host bridge: Broadcom BCM5785 [HT1000] Legacy South Bridge 00:02.1 IDE interface: Broadcom BCM5785 [HT1000] IDE 00:02.2 ISA bridge: Broadcom BCM5785 [HT1000] LPC 00:03.0 USB Controller: Broadcom BCM5785 [HT1000] USB (rev 01) 00:03.1 USB Controller: Broadcom BCM5785 [HT1000] USB (rev 01) 00:03.2 USB Controller: Broadcom BCM5785 [HT1000] USB (rev 01) 00:05.0 VGA compatible controller: ATI Technologies Inc Rage XL (rev 27) 00:18.0 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] HyperTransport Technology Configuration 00:18.1 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Address Map 00:18.2 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] DRAM Controller 00:18.3 Host bridge: Advanced Micro Devices [AMD] K8 [Athlon64/Opteron] Miscellaneous Control 01:0d.0 PCI bridge: Broadcom BCM5785 [HT1000] PCI/PCI-X Bridge (rev b2) 01:0e.0 RAID bus controller: Broadcom BCM5785 [HT1000] SATA (Native SATA Mode) 02:03.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5704 Gigabit Ethernet (rev 10) 02:03.1 Ethernet controller: Broadcom Corporation NetXtreme BCM5704 Gigabit Ethernet (rev 10)
Look for video controller / vga keywords in above output listing.
It is a good idea to run update-pciids command to fetches the current version of the pci.ids file from the primary distribution site and installs it. You must run update-pciids command as root user:
$ sudo update-pciids
Hardware information GUI tool
Under Ubuntu Linux you can open hardware information GUI tool by clicking on:
System > Preferences > Hardware information
System > Preferences > Hardware information
Nothing ever need be a mystery on Linux as it has a large number of excellent utilities for discovering hardware and monitoring hardware health. Here are a handful of good tools for spotting possible hard drive failure, displaying hardware information and monitoring temperatures, fans, voltages, email, music players and more.
Hard Drive Health
You're probably familiar with the excellent smartmontools for monitoring hard drive health, and getting early warning of possible drive failure. Smartmontools runs tests and reads data on drives that have the Self-Monitoring, Analysis and Reporting Technology (S.M.A.R.T.) system built into them. It's been around seemingly forever, but did you know there is a graphical interface for it? SmartControl puts a nice interface on smartmontools and supports all of its functions.
You can run a short or long self-test with a button click, and GSmartControl is especially valuable for quickly and easily finding log files and reading SMART attributes data, reading test results, and seeing detailed data on your hard drives.
Monitoring and Alerting
It's not fun when your first warning of a failed CPU fan is a melted-down CPU. lm-sensors is still my top choice for monitoring temperatures, fans, and voltages:
$ sensors atk0110-acpi-0 Adapter: ACPI interface Vcore Voltage: +1.23 V (min = +0.85 V, max = +1.60 V) +3.3 Voltage: +3.31 V (min = +2.97 V, max = +3.63 V) +5 Voltage: +4.97 V (min = +4.50 V, max = +5.50 V) +12 Voltage: +12.15 V (min = +10.20 V, max = +13.80 V) CPU FAN Speed: 3183 RPM (min = 600 RPM) CPU Temperature: +44.0Â°C (high = +60.0Â°C, crit = +95.0Â°C) MB Temperature: +40.0Â°C (high = +45.0Â°C, crit = +75.0Â°C)
I wish for a nice graphical front-end and alerter to lm-sensors; GNOME and KDE release nice ones and then they disappear. Xsensors is simple, the xfce4-sensors-plugin looks great in XFCE, and the KDE4 System Monitor widget is all right, but it's not very configurable and does no alerting. psensor is a rather nice, and it can run as a server for remote monitoring. GKrellM is an old favorite cram-full of features, alerting, and configurability.
Conky takes the prize for most objects supported. In addition to the usual system monitors it monitors email, music players, instant messaging, logfiles, weather forecast, and pretty much anything you want. If there isn't a plugin to do what you want you can write one.
It helps to know what is on your system, and you're probably familiar with the
lscpicommand for getting detailed information on everything connected to the PCI bus. Here are a few options you may not know about:
lspciwith no options shows a hardware list with vendor names, chipsets, and device types.
lspci -kdisplays the kernel driver in use for each device, and available kernel modules, like this example for an Nvidia graphics card:
01:00.0 VGA compatible controller: nVidia Corporation G98 [GeForce 8400 GS] (rev a1) Subsystem: Micro-Star International Co., Ltd. Device 1162 Kernel driver in use: nvidia Kernel modules: nvidia_current, nouveau, nvidiafb
lspci -tdisplays a tree view that shows the relationships between your devices.
The vendor names, chipsets, subsystems, device classes-- all the information displayed by
lspcicomes from a giant database, the PCI ID Repository. You can update your local copy of this database,
/usr/share/misc/pci.ids, by running the
update-pciidscommand as root.
dmidecodeis a wonderful utility for getting information about everything on your motherboard without opening the case, or booting to the BIOS. If you run
dmidecodewith no options it spits out pages of data. You can select what you want to see by consulting the DMI types table in
man dmidecode. Here are some examples.
How much RAM does your motherboard support?
$ sudo dmidecode -t 16 # dmidecode 2.9 SMBIOS 2.5 present. Handle 0x0033, DMI type 16, 15 bytes Physical Memory Array Location: System Board Or Motherboard Use: System Memory Error Correction Type: None Maximum Capacity: 16 GB Error Information Handle: Not Provided Number Of Devices: 4
How much RAM is installed, and in which slots? This example has most of the output snipped:
$ sudo dmidecode -t 17 # dmidecode 2.9 SMBIOS 2.5 present. Handle 0x0035, DMI type 17, 27 bytes Memory Device Total Width: 64 bits Data Width: 64 bits Size: 2048 MB Form Factor: DIMM Set: None Locator: DIMM0 Bank Locator: BANK0 Type: DDR2 Type Detail: Synchronous Speed: 800 MHz (1.2 ns)
What are the onboard devices, such as video, networking, sound?
$ sudo dmidecode -t 10 # dmidecode 2.9 SMBIOS 2.5 present. Handle 0x002C, DMI type 10, 6 bytes On Board Device Information Type: Video Status: Enabled Description: ATI Handle 0x002D, DMI type 10, 6 bytes On Board Device Information Type: Ethernet Status: Enabled Description: To Be Filled By O.E.M.
And much, much more, which is all detailed in the man page.
lshwcommand also gives a detailed peek inside your PC, and you can invoke its graphical view with
lshw -X(left). It's a little weird to navigate, but everything is there.
I like the way
lshwpresents information. It includes details like filesystem types and sizes, bus information, and capabilities. It has a couple of nice extras: the
-sanitizeoption scrubs IP addresses, serial numbers, and other identifiers, and the
-classoption lets you choose categories such as volume and disk for block devices, memory, and display. Run
lshw -shortto see what the categories are. Here is an abbreviated example:
$ sudo lshw -short H/W path Device Class Description ===================================================== /0/33/2 memory 2GiB DIMM DDR2 Synchronous 800 MHz (1.2 ns /0/33/3 memory DIMM [empty] /0/100/a/0 eth0 network RTL8111/8168B PCI Express Gigabit Ethernet /0/100/11/0 /dev/sda disk 2TB SAMSUNG HD204UI /0/100/11/0/1 /dev/sda1 volume 1651GiB EXT4 volume /0/100/11/0/2 /dev/sda2 volume 211GiB EXT4 volume /0/100/11/1 /dev/sdb disk 640GB WDC WD6401AALS-0 /0/100/11/1/1 /dev/sdb1 volume 27GiB EXT4 volume /0/100/11/1/2 /dev/sdb2 volume 1907MiB Linux swap volume /0/100/11/0.0.0 /dev/cdrom2 disk iHAS424 B /1 wlan0 network Wireless interface
